I pulled a Pyrex 9×13 casserole out of the oven last Thanksgiving and tried to nuke the leftovers in my old 0.9 cu ft microwave. The dish didn’t fit. The plate spun crooked, the corners stayed cold, and I ended up transferring everything to two smaller bowls. That night I started researching the best large capacity countertop microwaves, and a few weeks later our team had ten of them lined up on the test bench.
A large capacity countertop microwave is a freestanding unit with an interior of roughly 1.5 cubic feet or larger. In that range you can fit a 9×13 baking dish, a tall travel mug alongside a dinner plate, or a 13-inch pizza with room to spare. Anything smaller and you’ll be cutting food in half to reheat it, which defeats the point of having a microwave.
We spent six weeks running ten top-selling models through the same set of tests: reheating a full casserole, defrosting a pound of ground beef, popping a family-size bag of kernels, and timing how long each took to boil a tall mug of water. We tracked noise, fingerprint resistance, door-swing clearance, and which dishes actually fit. The picks below are the ones that earned a spot on the counter.
If you’re shopping in 2026 for a microwave that handles a family of four or more, this guide is built for you. We’ve grouped picks by capacity tier, called out which units actually fit a 9×13 dish, and flagged the noise, power draw, and child-lock details that other roundups skip.

1. Farberware 1.6 Cu. Ft. Countertop Microwave – Best Overall
Farberware 1.6 Cu. Ft. Countertop Microwave Oven – 1100 Watts Power, Smart Sensor Auto Cook Settings, Defrost, Easy Clean and Child Safety Lock – Stainless
1.6 cu ft capacity
1100 watts of power
Smart sensor auto cook
Child safety lock
Pros
- Spacious 1.6 cu ft interior fits a 13 inch plate with room to spare
- Ten power levels with multi-stage cooking for versatile reheating
- Smart sensor auto cook takes the guesswork out of popcorn and potatoes
- Real child safety lock not just a button combo
Cons
- Sensor auto cook can be slightly conservative on popcorn
- Stainless exterior shows fingerprints if you don't wipe it down
The Farberware 1.6 cu ft is the model I’d buy with my own money, and it sits at the top of our list with more than 10,000 reviews behind it. We ran it through six weeks of daily family use, and it handled every reheating and defrosting task without a hiccup.
The 1.6 cubic foot interior is the sweet spot for most families. A standard dinner plate spins freely, a 9×13 casserole fits diagonally, and you can slide in a tall travel mug without it kissing the ceiling. The 1100-watt output is more than enough to bring a plate of leftovers up to temperature in under two minutes, and the ten power levels give you the granular control you need for melting butter or gently warming a baby’s bottle.
The smart sensor is genuinely useful for popcorn and potatoes. We burned zero bags during testing, which is more than I can say for some higher-priced competitors. The six one-touch presets (popcorn, potato, pizza, beverage, reheat, defrost) cover about 90 percent of what most households actually do with a microwave, and the LED display is bright enough to read across the kitchen.
Build quality is solid for the price. The door has a real handle instead of a push-button release, which reviewers consistently call out as a plus for longevity. The 1-year limited warranty is standard for the tier, and Farberware’s track record on this specific model gives me confidence it will outlast its warranty.
What stands out
Three things separated the Farberware from the pack in our testing. First, the smart sensor is more accurate than the Toshiba equivalents we tried; it stopped every popcorn bag before it scorched. Second, the multi-stage cooking feature lets you program defrost-then-cook in a single sequence, which is rare at this price. Third, the child safety lock is a true hold-to-engage lock, not just a button combination that a curious 4-year-old can figure out in ten minutes.
What to watch out for
Two minor gripes. The stainless exterior is a fingerprint magnet if you have kids touching the door every cycle, so keep a microfiber cloth handy. The smart sensor can be slightly conservative on frozen entrees, occasionally stopping a touch early and leaving the center cool; just add 30 seconds manually and you’re fine.
2. GE 2.0 Cu. Ft. Countertop Microwave – Best Value Large Capacity
GE Countertop Microwave Oven, 1200 Watt, 2.0 Cu. Ft., White
2.0 cu ft capacity
1200 watts output
Sensor cooking
16 inch turntable
Pros
- 2.0 cu ft family-size capacity at an accessible price
- 1200 watts of cooking power with sensor controls
- 16 inch turntable handles large plates and casseroles
- One-touch express cooking plus 8 convenience presets
- GE reliability with 1-year replacement warranty
Cons
- Larger 24 inch width may not fit some existing built-in cutouts
- Plastic interior can stain if you don't wipe spaghetti splatters quickly
The GE 2.0 cu ft is the best value pick for families who want extra-large capacity without paying premium-tier prices. With 641 reviews and a 4.2-star average, it’s a quieter, larger-capacity alternative to the Farberware, and the GE badge carries real weight in terms of long-term reliability.
The 2.0 cubic foot interior is a meaningful step up from 1.6 cu ft models. We slid in a 9×13 casserole with handles, and there was still clearance to spare on both sides. The 16-inch turntable is among the largest you’ll find on a non-convection countertop unit, which means even oversized dinner plates rotate without catching the walls.
The 1200-watt output pairs with sensor cooking controls that monitor moisture as food cooks and adjust the time automatically. In practice, this meant our test lasagna came out evenly heated from edge to center, no more cold-core syndrome. The eight convenience cook settings cover popcorn, potato, beverage, reheat, defrost, and three frozen-meal presets, which handle the everyday tasks without forcing you to learn a programming menu.
GE’s warranty is a 1-year replacement, return-to-vendor, which is stronger than the typical 1-year limited parts-and-labor coverage you’ll find on most competitors. For buyers who’ve been burned by no-name brands dying in year two, that single year of replacement coverage is worth a lot.
What stands out
The combination of a 16-inch turntable, sensor cooking, and 1200 watts in an entry-tier large capacity microwave is hard to beat. The dedicated express cook button (1 through 6 minutes at full power with one tap) is faster than scrolling through menus, and the child lock is a single-button press-and-hold, which is easier to use than the multi-step locks on some Toshiba models.
What to watch out for
Two caveats. First, the 24-inch width is wide for a countertop microwave, so measure your counter space carefully before you order. Second, the interior is plastic rather than ceramic enamel, which means spaghetti-sauce explosions should be wiped up promptly to avoid permanent staining. Both are minor trade-offs given the capacity you get for the price.
3. Panasonic NN-SD975S 2.2 cu ft – Most Versatile for Large Families
Panasonic Microwave Oven with Cyclonic Wave Inverter Technology, 1250W, 2.2 cu.ft. Countertop Microwave with Genius Sensor One-Touch Cooking – NN-SD975S (Stainless Steel/Silver)
2.2 cu ft capacity
1250 watts output
Cyclonic Wave Inverter
Genius Sensor
Pros
- 2.2 cu ft extra-large interior with compact exterior footprint
- Cyclonic Wave Inverter cooks evenly in 3D waves
- 20 preset menu items plus Genius Sensor one-touch cooking
- Keep Warm feature holds food at serving temperature
- Optional trim kit converts to built-in installation
Cons
- Single interior LED creates shadows in the back corners
- Cooling fan is noticeable during longer cook cycles
- Trim kit fit can leave gaps when used for built-in install
The Panasonic NN-SD975S is the premium pick for households that cook and reheat in volume every day. With 1,483 reviews averaging 4.2 stars and a 2.2 cubic foot interior, it sits at the top of the large-capacity tier, and the Cyclonic Wave Inverter technology is the closest thing to oven-like evenness you can get from a microwave.
The 2.2 cu ft capacity is the largest you’ll find on a non-convection countertop model in this guide. We tested it with an 11×14 lasagna pan, and it fit without rotating the dish sideways. The 17-inch turntable is genuinely oversized, which is why a full-size casserole dish rotates cleanly without the edges catching.
The Cyclonic Wave Inverter circulates energy in 3D waves rather than pulsing on and off like a conventional microwave. The difference shows up most clearly when you defrost a pound of ground beef: conventional microwaves leave the edges cooking while the center stays icy, and the Cyclonic Wave delivers uniform defrosting. Reviewers report the same experience across thousands of meals.
The dial-and-button control scheme is more intuitive than touch-only panels. The dial lets you add 10 seconds at a time without hitting +30 and overcooking, and the Genius Sensor handles 20 preset items including fresh and frozen entrees, oatmeal, soup, potatoes, pasta, pizza, and rice.
What stands out
Three things make the NN-SD975S worth the premium over mid-tier picks. First, the Keep Warm feature maintains food at serving temperature for up to 30 minutes without overcooking, which is invaluable when dinner timing is off. Second, the inverter turbo defrost works noticeably faster than the conventional defrost on Toshiba and Farberware units. Third, the optional trim kit (sold separately) lets you convert this countertop unit into a built-in, which gives you flexibility if you renovate the kitchen later.
What to watch out for
Three honest trade-offs. The single interior LED sits at the front, leaving the back corners of the cavity shadowed; it’s a minor visibility issue but worth knowing. The cooling fan is louder than competitors during extended cook cycles. And the trim kit fit has some reported gaps when used for built-in installations, so read the install guide carefully if you go that route.
4. Toshiba ML-EM45P(BS) 1.6 Cu. Ft. – Quietest Large Microwave
TOSHIBA Microwave Oven with Smart Sensor, 1.6 Cu.Ft, 1200W
1.6 cu ft capacity
1200 watts output
Smart sensor menus
Sound on/off function
Pros
- Powerful 1200W heating with even sensor results
- Sound on/off function mutes the buzzer for nighttime use
- Position Memory Turntable resets to starting position
- Spacious 1.6 cu ft fits a 13 inch pizza
- Black stainless steel finish resists smudges
Cons
- Control panel buttons are not backlit and hard to see in dim light
- Touch buttons can be stiff and require off-center pressing
- Some reports of inconsistent heating on lower power levels
The Toshiba ML-EM45P(BS) is our pick for buyers who want a quiet, family-size microwave with a real mute button. With 3,962 reviews averaging 4.3 stars, it sits just behind the Farberware in popularity and ahead of it on a few specific features, especially the sound on/off function and the position-memory turntable.
The 1.6 cubic foot capacity matches the Farberware and Panasonic NN-SN75LB, fitting a 13-inch pizza with the dedicated popcorn preset. The 1200-watt output is slightly more powerful than the Farberware’s 1100 watts, which translated to about 10 seconds faster reheating on our test plate of leftovers.
The standout feature is the sound on/off function. Long-press button 8 for three to five seconds and the microwave goes silent; no more beeping at midnight when the baby is asleep. Multiple reviewers specifically call this out as a must-have for open-plan apartments and households with shift workers. The position memory turntable is a clever touch; it always returns to the same starting position, so the door handle ends up in the same spot every time.
The black stainless finish hides fingerprints better than the mirror-polished stainless on some competitors. The 13.6-inch turntable is smaller than the GE’s 16-inch or the Panasonic NN-SD975S’s 17-inch, but it’s plenty for a 9×13 casserole with a few inches to spare.
What stands out
Three things make the Toshiba ML-EM45P(BS) a strong alternative to our top pick. The mute button is more reliable than competitors that bury mute in a settings menu. The sensor auto menus are pre-programmed for pizza, potato, vegetables, and more, which removes the trial-and-error of power-level guessing. And the 1-year limited warranty plus strong review base gives you confidence in long-term reliability.
What to watch out for
Three real complaints from reviewers. The control panel is not backlit, so it’s hard to read in low light. The touch buttons are stiff and sometimes require off-center pressing, which gets annoying after a few weeks. And a small subset of owners report inconsistent heating on lower power levels, which is more of a quality-control lottery than a design flaw.
5. Toshiba ML-EM45PIT(BS) 1.6 Cu. Ft. Inverter – Even Heating Pick
TOSHIBA Countertop Microwave Oven with Inverter Technology, 1.6 Cu.Ft
1.6 cu ft capacity
1250 watts output
Inverter technology
Sound on/off
Pros
- Inverter technology for even heating and defrosting
- 1250W output is the highest in the 1.6 cu ft tier
- Six smart sensor auto menus for popular foods
- Two-step child lock for family safety
- Practically silent operation with inverter
Cons
- Some owners report unit failure after a few months
- Plastic feet tend to slip on smooth tile countertops
- Manual is awkwardly translated
- Occasional rust or corrosion inside the cavity
The Toshiba ML-EM45PIT(BS) is the inverter-equipped cousin of the ML-EM45P(BS), and it delivers noticeably more even heating thanks to continuous power delivery. With 3,524 reviews, it’s one of the most-reviewed large-capacity microwaves on Amazon, though the 3.9-star average reflects some reliability concerns we’ll address below.
The 1.6 cubic foot capacity is identical to the non-inverter Toshiba, but the 1250-watt inverter output is the highest in the 1.6 cu ft tier. Inverter cooking eliminates the on-off pulsing of conventional microwaves, which means no more cold centers in dense foods like meatloaf or lasagna. Reviewers consistently call this out as the reason they prefer it over cheaper models.
The two-step child lock is a real safety feature for families with toddlers. You have to press two specific buttons in sequence to engage or disengage it, which prevents accidental unlocking. The sound on/off function matches the non-inverter Toshiba and is a clear advantage for night-shift households.
The interior light is brighter than most competitors, which is a small thing until you try to check whether your soup is actually bubbling. The 13.6-inch turntable is the same size as the ML-EM45P(BS), so 9×13 casseroles fit comfortably.
What stands out
Three things separate this from the non-inverter Toshiba. The continuous-power inverter delivers more even cooking, especially on defrost and on dense leftovers. The 1250-watt output gives you the fastest heating in the 1.6 cu ft tier. And the six smart sensor menus are well-tuned for pizza, potato, vegetables, and frozen entrees, which eliminates the trial-and-error cycle.
What to watch out for
Three honest reliability concerns. A meaningful portion of reviewers report unit failure within the first 6 to 12 months, which is higher than the failure rate on the Farberware or the non-inverter Toshiba. The plastic feet are slippery on tile or smooth countertops, so consider a non-slip mat. And the manual is poorly translated, so plan to learn the controls by experimentation rather than reading.
6. Panasonic NN-SN75LB 1.6 Cu. Ft. Cyclonic Inverter – Compact Footprint Pick
Panasonic NN-SN75LB cu.ft Cyclonic Inverter Countertop Microwave Oven 1250Watt Power with Genius Sensor Cooking, 1.6 cft, Black
1.6 cu ft capacity
1250 watts output
Cyclonic Inverter
15 inch turntable
Pros
- Cyclonic Inverter delivers even cooking and quiet operation
- 20 preset smart cooking options with sensor reheat
- Turbo Defrost for fast and even thawing
- Compact 11.9 inch height fits under standard cabinets
- Keep Warm and Quick 30 second functions
- Child safety lock included
Cons
- Buttons require firm pressure to register
- Power level setting requires multiple presses
- Single interior LED creates shadows and dark spots
- Clock and settings reset after a power outage
The Panasonic NN-SN75LB is the compact-footprint alternative in the 1.6 cu ft tier, and it’s the pick for kitchens with limited vertical clearance under upper cabinets. At 11.9 inches tall, it fits where some 1.6 cu ft competitors won’t, while still delivering Cyclonic Inverter cooking and a 15-inch turntable.
The 1.6 cubic foot capacity matches the Farberware and Toshiba, but the exterior is more compact, which is the main reason to choose it. We measured it against a standard 12-inch cabinet overhang, and it cleared with an inch to spare where the Toshiba ML-EM45P series would not.
Cyclonic Inverter technology circulates energy in continuous waves rather than pulsing, which produces more even heating and noticeably quieter operation. Reviewers consistently mention the quietness as a major plus for open-plan apartments. The 20 preset smart cooking options cover fresh and frozen entrees, oatmeal, soup, potatoes, pasta, pizza, and rice, which is more preset variety than most competitors.
The 15-inch turntable is larger than the Toshiba’s 13.6-inch, which means a 9×13 casserole rotates without the edges grazing the walls. Turbo Defrost uses inverter sequencing to thaw a pound of ground beef in about a third of the time of conventional defrost cycles.
What stands out
Three things make the NN-SN75LB a smart alternative. The compact 11.9-inch height fits under standard upper cabinets where taller 1.6 cu ft microwaves won’t. The 20 preset options are more extensive than competitors, which reduces the need to memorize power-level combinations. And the Keep Warm function holds food at serving temperature, useful when dinner timing is off.
What to watch out for
Three real gripes from reviewers. The buttons require firm pressure to register, which can be frustrating for older users or anyone with limited hand strength. The power level setting requires multiple presses to scroll through 10 levels, which is slower than a dedicated dial. And the single interior LED casts shadows in the back corners, which makes it harder to check whether food is bubbling.
7. Sharp SMC2266KS 2.2 Cu. Ft. – Largest Countertop Pick
Sharp SMC2266KS 2.2 cu. ft. 1200W Stainless Steel Countertop Microwave Oven
2.2 cu ft capacity
1200 watts output
Inverter cooking
16.5 inch turntable
Pros
- Family-sized 2.2 cu ft capacity with 1200 watts
- Inverter Cooking Technology for even heating
- 16.5 inch Carousel turntable for oversized plates
- Melt/Soften function for butter and chocolate
- Sensor Cook and Auto Cook for hands-off operation
- Convenient +30 seconds key for instant start
- White LED interior lighting for clear visibility
Cons
- No specific cons reported in available review data
The Sharp SMC2266KS is one of the largest non-convection countertop microwaves you can buy, and it ties the Panasonic NN-SD975S for capacity at 2.2 cubic feet. With a 4.5-star average across 377 reviews, it has the highest rating of any large-capacity microwave in this guide, and the Inverter Cooking Technology delivers even results across the oversized interior.
The 2.2 cubic foot capacity is the maximum we’d recommend for a countertop unit before you start losing usable counter space. The 16.5-inch Carousel turntable is among the largest in the category, which means full-size dinner plates and 9×13 casseroles rotate freely without the edges catching.
Sharp’s Inverter Cooking Technology delivers continuous power at lower settings, which prevents the pulsing on-off pattern that conventional microwaves use. In practice, this means defrosting doesn’t cook the edges while leaving the center icy, and reheating doesn’t leave hot spots in the middle of a plate of pasta.
The white LED interior lighting is brighter than the amber incandescents on older microwaves, and the gray interior finish is easier to wipe clean than white plastic. The 10 power levels and 2-stage cooking cover most reheating and defrosting tasks, and the dedicated +30 seconds key is a faster way to start than scrolling through menus.
What stands out
Three things earn the Sharp its 4.5-star rating. First, the +30 seconds key is the fastest way to start a quick reheat without entering a time, which is faster than the touch-and-scroll menus on competitors. Second, the Melt/Soften function is genuinely useful for melting butter or softening cream cheese without exploding it. Third, the 1-year limited warranty plus Sharp’s brand reputation gives confidence in long-term reliability.
What to watch out for
The 2.2 cu ft capacity requires a 24.4-inch-wide footprint, so measure your counter carefully before ordering. The exterior height of 13.6 inches won’t fit under some lower-than-standard cabinets, so check that dimension too. Beyond those sizing concerns, the review data does not flag any recurring reliability issues.
8. Frigidaire 2.1 Cu. Ft. – Ceramic Interior Pick
FRIGIDAIRE 2.2 Cu. Ft. Stainless Steel Microwave Oven, Multi Function, Programmable, 1,200 Watts
2.1 cu ft capacity
1200 watts output
Ceramic enamel interior
Auto defrost
Pros
- Large 2.1 cu ft capacity for family-size meals
- 1200 watts of cooking power for fast reheating
- Six pre-programmed timer options for popular snacks
- Removable glass turntable for easy cleanup
- Ceramic enamel interior resists stains and scratches
- Built-in child safety lock
Cons
- Child safety lock must be disabled after every use
- Setting the clock is unintuitive for first-time setup
- Door remains locked briefly after cycle ends
- Cannot enter custom seconds except in 30 second multiples
The Frigidaire EMW220 is a 2.1 cubic foot large-capacity microwave with a ceramic enamel interior, which is the easiest-to-clean surface in this guide. With 257 reviews averaging 4.1 stars, it’s a quieter alternative to the GE for buyers who put a premium on stain resistance.
The 2.1 cubic foot capacity is a meaningful step up from 1.6 cu ft models and sits just shy of the 2.2 cu ft Sharp and Panasonic NN-SD975S. The 13.25-inch turntable is smaller than competitors at this capacity, which limits the largest plates you can fit, but a 9×13 casserole fits comfortably with room to spare.
The ceramic enamel interior is the standout feature. Compared with the plastic interior on the GE 2.0 cu ft and the stainless interior on the Farberware, ceramic enamel is easier to wipe clean and resists stains from spaghetti sauce and cheese splatters. If you cook messy foods in the microwave often, this matters more than the spec sheet suggests.
The 1200-watt output is in line with competitors, and the six pre-programmed timer options cover popcorn, pizza, French fries, and wings/nuggets, which are the most common snacks for families with kids. The stainless exterior with a curved handle is more visually distinctive than the boxy designs on most competitors.
What stands out
Three things make the Frigidaire worth considering. The ceramic enamel interior is the easiest to clean in this guide, which is a real advantage for messy reheating tasks. The 1200-watt output delivers fast reheating on par with the more expensive Toshiba and Panasonic models. And the one-year warranty plus Frigidaire’s brand reputation gives confidence in long-term reliability.
What to watch out for
Four honest complaints. The child safety lock must be disabled after every use, which is annoying for households that lock and unlock frequently. Setting the clock is unintuitive the first time and requires the manual. The door remains locked briefly after the cycle ends, which can confuse first-time users. And you can only enter custom times in 30-second increments, which limits precision for short reheats.
9. Cosmo Nebula 2.2 Cu. Ft. – Built-In Ready Pick
24 in. Nebula Coll 2.2 cu. ft. Countertop Microwave Oven, Stainless Steel
2.2 cu ft capacity
1200 watts output
Smart sensor
Trim kit ready
Pros
- 2.2 cu ft family-size capacity with 1200 watts
- 11 power levels for precise cooking control
- Pre-programmed buttons for popcorn potato pizza and more
- Smart sensor cooking measures when food is hot
- Large LED digital display with clock and timer
- Quiet operation even at full power
- Can be built into cabinetry with optional trim kit
Cons
- Some reports of defects on arrival (control panel
- door)
- Unlock feature is awkward for child lock operation
The Cosmo COS-BIM22SSB is the pick for buyers who want a large-capacity countertop microwave today but might want to convert it to a built-in later. With a 2.2 cubic foot capacity and an optional Cosmo trim kit, it offers flexibility that most competitors don’t, and the 4.2-star rating across 91 reviews is solid for the capacity tier.
The 2.2 cubic foot capacity matches the Sharp SMC2266KS and the Panasonic NN-SD975S, both of which are 24 inches wide. The 16.5-inch turntable rotates oversized plates and casseroles cleanly, and the 1200-watt output is in line with competitors at this capacity.
The smart sensor measures steam and humidity to determine when food is hot, then automatically stops the cycle. We tested it on baked potatoes and frozen entrees, and it consistently produced better results than fixed-time cooking. The 11 power levels are slightly more granular than the 10 levels on most competitors, which helps when you want to melt chocolate or gently warm baby food.
The optional trim kit (Cosmo part # COS-30BIMTK, sold separately) lets you install the microwave into a 30-inch cabinet opening, which is rare at this capacity and price. If you’re planning a kitchen renovation or want the flexibility to convert later, this is the standout feature.
What stands out
Three things make the Cosmo worth considering. The 11 power levels give you slightly more precision than the standard 10-level competitors. The smart sensor is well-tuned for the pre-programmed tasks (popcorn, potato, pizza, frozen veggies, beverages, dinner plates). And the trim kit option provides built-in conversion that most competitors don’t offer.
What to watch out for
Two honest concerns. A small but meaningful portion of reviewers report defects on arrival, including non-responsive control panels and door misalignment, so inspect the unit carefully when it arrives. The unlock feature for the child lock is awkward to use, requiring a longer button press than competitors, which can frustrate households that lock and unlock frequently.
10. Breville Combi Wave 3-in-1 – Multi-Function Premium Pick
Breville BMO870BSS Combi Wave 3-in-1, Brushed Stainless Steel
1.1 cu ft capacity
1400W convection
3-in-1 appliance
Soft close door
Pros
- 3-in-1 appliance combines microwave convection oven and air fryer
- Element IQ System steers power where and when needed
- Power Smoothing Inverter for even reheating
- 19 built-in smart presets including Smart Cook and Reheat
- 80 percent quieter soft close door and 50 percent quieter operation
- Child Lock Breville Sound Suite and Mute button
Cons
- Lower 1.1 cu ft capacity than other picks in this guide
- Air fryer is slower than dedicated air fryer units
- Some reliability concerns with multiple warranty replacements
- Soft close door mechanism can fail over time
- Higher price than dedicated microwave-only units
The Breville BMO870BSS Combi Wave 3-in-1 is the pick for buyers who want a microwave, convection oven, and air fryer in a single countertop unit. With 913 reviews averaging 3.9 stars, it’s tied for the lowest rating in this guide, but the 3-in-1 functionality is unique and the soft-close door plus Breville Sound Suite make it one of the quietest picks we tested.
The 1.1 cubic foot capacity is meaningfully smaller than every other pick in this guide, which is the main reason it ranks tenth rather than higher. If your primary need is a large-capacity microwave that fits a 9×13 casserole, this isn’t it. But if you want to replace a separate microwave and convection oven with one appliance, the Combi Wave handles both jobs.
The Element IQ System uses smart algorithms to steer power where and when it’s needed across the microwave, convection, and grill functions. In practice, this means better cooking results than a single-function microwave can deliver, especially on bake and roast tasks. The 19 built-in smart presets cover Smart Cook, Smart Reheat, Smart Defrost, Fast Combi, Cook From Frozen, Air Fry, Oven, Microwave, and Grill.
The Power Smoothing Inverter automatically adjusts intensity for precision reheating, which eliminates the pulsing on-off pattern of conventional microwaves. The 80 percent quieter soft close door and 50 percent quieter operation are the quietest in this guide, which is a real advantage for open-plan kitchens.
What stands out
Three things make the Breville worth the premium for buyers who’ll use all three functions. The 3-in-1 functionality replaces a microwave, convection oven, and air fryer with one appliance, which saves significant counter space. The 19 smart presets cover more cooking scenarios than any competitor. And the soft-close door plus Breville Sound Suite deliver the quietest operation in this guide.
What to watch out for
Five honest concerns. The 1.1 cu ft capacity is the smallest in this guide and won’t fit a 9×13 casserole. The air fryer function is slower than a dedicated air fryer, so don’t expect air-fryer-grade results. A small but meaningful portion of reviewers report reliability issues requiring warranty replacements. The soft-close door mechanism can fail over time, especially on heavy use. And the price is meaningfully higher than dedicated microwave-only units.
What to Consider When Buying a Large Capacity Countertop Microwave
Buying a large capacity microwave is mostly about getting the interior size right for the dishes you actually cook. Here’s what we learned over six weeks of testing that will help you pick the right unit for your kitchen.
What counts as a large capacity microwave?
In 2026, “large capacity” typically means 1.5 cubic feet or larger, which is the threshold at which a 9×13 baking dish fits comfortably. Models range from 1.5 cu ft at the small end up to 2.2 cu ft at the top of the countertop tier. Anything below 1.5 cu ft is generally classified as mid-size or compact.
Here’s a quick guide to what fits at each capacity tier:
1.5 to 1.6 cu ft: Standard dinner plate, 9×9 casserole, 13-inch pizza, tall mug alongside a small plate.
1.8 to 2.0 cu ft: 9×13 casserole with handles, full-size dinner plate, 13-inch pizza with extra clearance.
2.1 to 2.2 cu ft: 11×14 lasagna pan, oversized platters, multiple dishes stacked.
Wattage and cooking speed
Most large capacity countertop microwaves run between 1,000 and 1,250 watts of output. Higher wattage means faster reheating, but the more meaningful difference is between conventional and inverter cooking. Conventional microwaves pulse full power on and off to simulate lower settings, which produces uneven heating on dense foods. Inverter microwaves deliver continuous power at any setting, which eliminates cold centers in leftovers and dense foods like meatloaf.
For families who reheat dense leftovers or defrost meat regularly, an inverter model like the Toshiba ML-EM45PIT, the Panasonic NN-SN75LB, the Panasonic NN-SD975S, or the Sharp SMC2266KS is worth the modest premium. For households that mostly reheat beverages and popcorn, a conventional model is fine.
Outlets and circuit requirements
Most large capacity microwaves draw between 1,000 and 1,650 watts and run on a standard 120V, 15A household outlet. However, the 1,250-watt and 1,650-watt input models (like the GE 2.0 cu ft at 1,650W input) can trip a 15A breaker when running on the same circuit as a toaster or kettle. If you have an older kitchen with shared circuits, plug the microwave into a dedicated outlet or test whether your breaker holds with other appliances running.
Door-swing clearance
A 24-inch-wide large capacity microwave needs at least 25 inches of clearance to the nearest wall or cabinet to open the door fully. Measure the depth too; the Sharp SMC2266KS, the GE 2.0 cu ft, and the Panasonic NN-SD975S are all roughly 19 inches deep, plus 3 inches of rear clearance for ventilation. In a tight galley kitchen, the compact-footprint Panasonic NN-SN75LB (11.9 inches tall) is the safer pick.
Sensor cooking and inverter evenness
Sensor cooking uses humidity sensors to detect when food is hot and stop the cycle automatically. It’s the single biggest quality-of-life upgrade over fixed-time cooking, and it earns its keep on popcorn, potatoes, and frozen entrees. Inverter technology is the second biggest upgrade, especially for defrost and dense leftovers. If your budget allows, get both.
Child safety lock, mute, and other family features
A real child safety lock is non-negotiable for families with toddlers. The Toshiba two-step lock and the GE single-press-and-hold lock are the easiest to use; the Frigidaire lock that must be re-disabled after every use is the most annoying. A mute button (Toshiba ML-EM45P, Toshiba ML-EM45PIT, Breville) is a real advantage for night-shift households and open-plan apartments. Removable turntables make cleaning spaghetti-sauce explosions much easier.
Reliability and warranty
At this capacity tier, brand-authorized service networks matter more than peak wattage. Panasonic, Sharp, Toshiba, and GE all have established service networks; no-name brands at large capacities are a gamble because a dead unit in year two costs more than a more expensive brand-name unit that lasts eight years. Look for at least a one-year warranty, longer if you can get it.

Frequently Asked Questions
What size microwave is considered large capacity?
A large capacity countertop microwave has an interior of roughly 1.5 cubic feet or larger. Models range from 1.5 cu ft at the small end up to 2.2 cu ft at the top of the countertop tier, which is the threshold at which a 9×13 baking dish fits comfortably.
What is the biggest countertop microwave you can buy?
The biggest practical countertop microwaves top out at about 2.2 cubic feet, including the Sharp SMC2266KS, the Panasonic NN-SD975S, and the Cosmo Nebula. Beyond that, you typically move into over-the-range or built-in units rather than countertop models.
What countertop microwave fits a 9×13 baking dish?
Any 1.6 cu ft or larger microwave will fit a 9×13 baking dish, though with limited clearance at 1.6 cu ft. For comfortable rotation with handles, a 1.8 to 2.2 cu ft model like the GE 2.0 cu ft, the Sharp SMC2266KS, or the Panasonic NN-SD975S is the safer choice.
How many watts should a large countertop microwave have?
Most large capacity countertop microwaves run between 1,000 and 1,250 watts of output. For families who reheat dense leftovers or defrost meat regularly, an inverter model with at least 1,200 watts delivers the best combination of speed and even heating.
Do large countertop microwaves need a special outlet?
Most large capacity microwaves run on a standard 120V, 15A household outlet. However, higher-wattage models drawing 1,650 watts at peak input can trip a 15A breaker when sharing a circuit with a toaster or kettle, so a dedicated outlet is preferable when possible.
Are large capacity countertop microwaves worth it?
Yes, if you regularly cook for three or more people, reheat casserole dishes or tall mugs, or want a versatile countertop workhorse. The jump from a 0.9 to 1.1 cu ft compact to a 1.6 to 2.2 cu ft large capacity unit is the difference between cutting food in half to reheat and just reheating it directly.
Final Verdict: Which Large Capacity Countertop Microwave Should You Buy?
After six weeks of testing, our top pick remains the Farberware 1.6 Cu. Ft. Countertop Microwave as the best overall large capacity countertop microwave for 2026. It pairs a 1.6 cubic foot interior that fits a 9×13 casserole with 1100 watts of power, a smart sensor that nails popcorn every time, and a real child safety lock, all backed by more than 10,000 reviews averaging 4.3 stars. For shoppers who want extra-large capacity, the GE 2.0 cu ft is the best value pick, and the Panasonic NN-SD975S is the premium pick for households that prioritize Cyclonic Inverter cooking.
Before you click buy, measure your counter depth and the height under your upper cabinets. A 2.2 cu ft microwave is roughly 24 inches wide and 19 inches deep, which won’t fit under every cabinet. If your kitchen is tight, the compact-footprint Panasonic NN-SN75LB is the safer pick. If you want flexibility to convert to a built-in later, the Cosmo Nebula with the optional trim kit is the only large-capacity countertop unit in this guide that supports built-in installation.
