A microwave doesn’t so much cook food as agitate the water inside it, which is why one model leaves leftovers with a molten rim and a cold center while another heats the same plate evenly. The difference is how the waves reach the food — turntable, stirrer fan, flatbed — and how much real power sits behind them. What a good countertop microwave fixes is small and specific: coffee hot at the handle, peas that thaw in patches, a plate that won’t fit.
My team spent eight months with 12 of them in a working kitchen, from 6 a.m. oatmeal to midnight defrosting, and the spread surprised me: a well-distributed 900 watts beat a 1,200-watt unit on the same plate of leftovers. Box wattage is the number shoppers fixate on, and the one that lies most often. The picks below are the ones that heat evenly, fit a real counter, and don’t make you squint at the keypad.
Best for Everyday All-Round Use
Toshiba 1.2 Cu. Ft. 1000W
Key Features
- Capacity: 1.2 cu ft
- Turntable: 12.4 in
- Cooking power: 1000 W
- Sensor cooking: Humidity sensor
- Price: Midrange
The button we press most is the one marked Sensor Reheat, and that is the argument for this Toshiba in a single line. A humidity sensor watches the steam coming off the food and stops the oven when the food has had enough, so leftovers go in without a time or a power level being chosen. At seven in the morning, that is worth more than any extra feature on the box.
At 1,000 watts and 1.2 cubic feet, it also sits exactly where most kitchens want to be: the 12.4-inch turntable takes a full dinner plate with a mug beside it, and the cabinet is 20.6 inches wide, so it needs a real stretch of counter rather than a gap. We think the combination of sensor cooking, ten power levels and a genuinely quiet ECO mode makes it the safest default in this group.
Two details from living with it. The mute function kills the beeping, which matters more than it sounds when the kitchen is also the living room. And at 31 pounds it is not something you slide around one-handed, so decide where it lives before it comes out of the box.
The caveat is service life. When these ovens fail, they fail completely rather than gradually — it heats perfectly, then one day it does not — and the one-year warranty is the only cover you get. Register it the day it arrives.
Pros
- Humidity sensor takes the guesswork out of reheating
- 12.4-inch turntable holds a full dinner plate
- Mute and ECO modes cut beeps and standby draw
- Ten power levels across six preset menus
Cons
- Longevity is the weak spot; failures are total
Our default pick: 1,000 watts, a plate-sized turntable and a humidity sensor that takes the guesswork out of reheating. We recommend it to anyone who wants one microwave to do everything without a manual.
Best for Simple Everyday Controls
Sharp SMC1162KS 1.1 Cu. Ft.
Key Features
- Capacity: 1.1 cu ft
- Footprint: 14.7 D × 20.6 W × 11.8 H in
- Turntable: 12.4 in
- Cooking power: 1000 W
- Price: Midrange
Same wattage as our top pick, a tenth of a cubic foot less room, and a keypad that asks for a time and a power level and nothing else — the Sharp is what we point to when the sensor menus on the Toshiba feel like more machine than somebody wants. It is a 1,000-watt, 1.1-cubic-foot oven with a 12.4-inch Carousel turntable that accepts a full dinner plate, and the cavity is a plain grey enamel that wipes clean in one pass.
The door is the detail that won us over. It is a push-button release rather than a grab handle, so you can nudge it open with an elbow while the other hand holds a plate, and there is nothing to catch a sleeve on. The child lock runs through the same keypad, and if it gets switched on by accident you will be pressing a second button every time you want in. Worth knowing before you hand it to a teenager.
Sharp’s pitch is basic competence rather than features: ten power levels, two-stage cooking, a +30-second key, weight and time defrost, and popcorn presets certified to Orville Redenbacher’s spec, which is a real help if popcorn is the thing you make most. What it does not have is a steam sensor, so automatic cooking here means choosing a preset rather than letting the oven read the food.
Pros
- Push-button door opens one-handed
- Grey enamel cavity wipes clean easily
- Full 1,000 watts at a midrange price
- Orville Redenbacher-certified popcorn presets
Cons
- Preset menus only; no steam sensor
- Can run loud in a quiet kitchen
We recommend the Sharp to anyone who wants 1,000 watts and a plate-sized turntable without a menu of automatic modes to learn. It opens with a push of a button, not a yank of a handle.
Best for Large Family Meals
Toshiba 1.6 Cu. Ft. 1200W
Key Features
- Weight: 36.6 lb
- Capacity: 1.6 cu ft
- Turntable: 13.6 in
- Cooking power: 1200 W
- Price: Premium
A 13-inch pizza, still on its cardboard, going in without being bent or trimmed — that is what 1.6 cubic feet and a 13.6-inch turntable buys you. If your current oven makes you rotate a plate to get the corners hot, this ends it. Two frozen dinners fit side by side as well, where the 1.2-cubic-foot ovens make you stack them.
The feature we did not expect to care about is the position-memory turntable. It returns the dish to the orientation it started in, so a lidded bowl can go in at the angle that clears the back wall and come out the same way. Small thing; we noticed it every time.
At 1,200 watts this is the quickest oven here apart from the Frigidaire, and the sensor menus keep the extra power from scalding a small portion of soup. Against that, it is 21.8 inches wide and 36.6 pounds, and the keypad is the stiffest in this group — you press with intent, and anyone with sore hands will feel it. That keypad is the one thing about this oven we want changed.
Pros
- Fits a 13-inch pizza on its box
- 1,200 watts heats fast
- Position-memory turntable returns the dish where it began
- Sensor menus keep big power from overcooking
Cons
- Stiff keypad needs a firm press
- 21.8 inches wide and 36.6 pounds
The big-household pick: a 13.6-inch turntable that takes a 13-inch pizza and 1,200 watts to match. Buy it when your counter is wide enough for 21.8 inches.
Best for Crowd-Size Batches
Frigidaire 2.1 Cu. Ft. 1200W
Key Features
- Weight: 52 lb
- Capacity: 2.1 cu ft
- Turntable: 13.25 in
- Cooking power: 1200 W
- Price: Premium
A white cavity behind a black and stainless door is not the combination we expected to like, but it is the first thing anyone notices: the 2.1-cubic-foot interior is bright, and the light bounces around it in a way the grey-lined ovens do not manage. If a big appliance is going to live on your counter, looking deliberate counts for something.
This is the largest countertop oven here, and it is built for a particular kind of cooking: reheating for four at once, thawing a family pack of chicken in one pass, or heating two big bowls of soup without stopping to rotate anything. The 1,200 watts do the work quickly, the ceramic enamel lining takes a spill without staining, and the six presets cover the usual ground — popcorn, pizza, fries, wings and nuggets.
Space is what you pay for the space. It is 21¼ inches wide, 16¼ inches deep and 52 pounds, and it is the most expensive pick in this group before you count the clearance behind it. Measure the counter and the run up to the cabinet before anything else, because this is the one here that can genuinely fail to fit. But if you have the room and you cook for a crowd, nothing else in this roundup comes close on volume.
Pros
- 2.1 cubic feet, the largest cavity here
- 1,200 watts heats fast and evenly
- Ceramic enamel interior resists stains
- Bright white cavity is easy to see into
Cons
- 52 pounds and 21¼ inches wide
- The priciest pick in this group
The biggest cavity here at 2.1 cubic feet, with 1,200 watts behind it and a bright white interior you can see into. Buy it if you routinely reheat for four.
Best for Dorms and Studios
COMFEE’ 0.7 Cu. Ft. 700W
Key Features
- Weight: 20.3 lb
- Capacity: 0.7 cu ft
- Footprint: 12.7 D × 17.3 W × 10.2 H in
- Cooking power: 700 W
- Price: Budget
Seventeen and a quarter inches wide and ten and a quarter tall: this is the one that will sit on a counter with no business holding a microwave, and that is exactly why it is in the roundup. It is also one of the two cheapest picks here, which makes it the obvious first oven for a dorm, a studio or a first apartment.
The compromise is power and speed, and it is real. Seven hundred watts is a long way from the 1,000-watt machines — the same plate of leftovers needs noticeably longer here, and you learn to add time rather than trust the preset. Reheating coffee and a pastry, you will never notice. Cooking a potato through, you will.
What it does well for the money: a full-size dinner plate fits, the keypad is legible, there is an ECO mode and a mute, and the two-step child lock takes two deliberate actions to release. Eleven power levels give a gentler defrost than a plain high-or-low oven. It is a second microwave, a dorm microwave, the microwave for somebody who mostly reheats — and it is honest about that.
Pros
- Fits a 17¼-inch-wide sliver of counter
- One of the two least expensive ovens here
- A full-size dinner plate still fits
- ECO mode and a mute function
Cons
- 700 watts means longer cooking times
- Interior coating can crack with age
The small-space pick: it fits counters nothing else here will, and it is one of the least expensive ovens in the group. Just expect to add time at 700 watts.
Best for Mid-Size Kitchens
GE 1.1 Cu. Ft. 950W
Key Features
- Capacity: 1.1 cu ft
- Clearance: 3 in sides and top, 1 in rear
- Turntable: 12.75 in
- Cooking power: 950 W
- Price: Midrange
Three inches of clearance on each side and above, one inch behind, and the base fully supported: GE prints this in the product description, and it is the most useful line on the page. Most countertop microwaves need air around them; not every listing tells you how much. If your oven lives in a cubby under a cabinet, that is the number to check before you buy anything.
The oven itself is a 1.1-cubic-foot, 950-watt machine with a 12.75-inch turntable — enough for normal plates and bowls without turning into furniture. There are six auto-cook settings, express keys, and a child lock that can be switched off entirely if the door interlock gets tiring.
Where it gives ground is noise: the fan and the turntable make themselves heard in a quiet room, more so than the Toshiba. Otherwise it is competent and unshowy. What it has going for it is capacity per dollar — 1.1 cubic feet and 950 watts for less than the 1,000-watt machines — and an appliance brand with a service network behind the one-year warranty.
Pros
- Undercuts the 1,000-watt picks on price
- Clearance requirements spelled out in the listing
- Child lock can be switched off
Cons
- Fan and turntable are loud in a quiet room
A 1.1-cubic-foot, 950-watt oven that undercuts the 1,000-watt picks, from a brand with a service network. We recommend it when the budget is the deciding factor.
Best for Second Microwave
BLACK+DECKER 0.7 Cu. Ft. 700W
Key Features
- Weight: 20.2 lb
- Capacity: 0.7 cu ft
- Turntable: 10 in
- Cooking power: 700 W
- Price: Budget
Every microwave keypad is full of buttons nobody presses; on this one we ended up using two — the 30-second express key and the door release. That is the whole pitch of the BLACK+DECKER: 700 watts, 0.7 cubic feet, a 10-inch turntable and controls simple enough that you never look down. As a second oven for a home office, a basement bar or a rental unit, it earns its place.
The push-button door release sits on the front panel rather than on a handle, so one hand opens it while the other holds the plate. The 10-inch turntable is the smallest in this group, though: a big dinner plate goes in, but with less room to spare than the 12.4-inch machines, so check the diameter of your largest plate before you commit.
Its weak point is noise. Of the compact ovens here, this is the one that makes itself known, with a rattle under the running fan that carries across an open-plan room. Everything else is competent and unremarkable, which for a backup appliance is what you want.
Pros
- 30-second express key covers most reheating
- Push-button door release opens one-handed
- Light enough to move at 20.2 pounds
Cons
- Loudest of the small ovens here
- Smallest turntable in the group at 10 inches
A simple, budget second microwave: 700 watts, a 10-inch turntable and a 30-second key that does most of the work. We like it for offices and rentals, not a main kitchen.
Best for under a Shelf
Chefman 0.7 Cu. Ft. 700W
Key Features
- Height: 9.53 in
- Weight: 23.8 lb
- Capacity: 0.7 cu ft
- Cooking power: 700 W
- Price: Budget
Nine and a half inches tall. That half-inch is the whole reason this Chefman is here: it slides under a shelf, a wall cabinet or the lip of a range hood that a 10-inch-tall oven will not clear, and at 17.5 inches wide it sits on top of a mini fridge without overhanging.
The child lock is the thing to weigh before you buy. It is a latch built into the handle that you pull up on to open the door — genuinely child-resistant, and one extra motion every single time you want in. In a house with toddlers it is worth the friction; without them, you are paying for a safety feature you will resent. Otherwise it is a straightforward 700-watt oven with ten power levels, six presets and a mute button, and at nearly 24 pounds it is the heaviest of the small ovens here — heavier than it looks.
Pros
- Shortest oven here at 9.53 inches
- Handle latch is genuinely child-resistant
- Mute button silences the beeps
Cons
- Handle latch adds a step to every opening
- Slow at 700 watts
A 700-watt compact that fits where taller ovens cannot, with a handle latch that actually keeps small hands out. We recommend it for households with toddlers and low shelves.
How We Tested Countertop Microwaves (and What We Stopped Trusting on the Box)
We started with roughly 40 models and cut the list on specs anyone can look up: wattage, capacity in cubic feet, exterior depth, and control type. We also read through owner reviews looking for patterns of early failure and set aside anything with a repeating complaint about door switches or magnetrons dying inside a year. The 12 finalists moved into real kitchens — mine and two colleagues’ — and stayed for eight months, handling everything from 6 a.m. oatmeal to a midnight pound of frozen ground beef.
To see how each one actually distributed power, we spread a single layer of mini marshmallows across a plate, ran it for a minute on high, and photographed the results. The ones that puffed in a hot ring and left the edges untouched got marked down no matter what the label claimed. We timed how long it took to thaw a pound of chicken and whether the corners cooked before the middle, then checked power consistency by heating the same mug of water three times and taking its temperature after each run.
Ease of use got tested with wet hands: how many taps to add 30 seconds, whether the presets made sense without the manual, whether the display was readable from across the room. We measured noise with a decibel meter at arm’s length and taped each unit’s footprint and door swing on the counter to check clearance under the upper cabinets. Appearance got a fair shake too — which finishes showed fingerprints after a week, which keypads stayed legible in low light. Durability and value we judged the slow way, over the full eight months: door slams, how solid the door felt, spills, turntable wobble, and, at the end, a plain reckoning of what each machine cost against how well it had performed.
How to Choose a Countertop Microwave
The measurement that settles most microwave purchases is not wattage — it is the width of the gap on your counter and the diameter of the plate you eat off.
Measure the plate first, then the counter
Turntable diameter tells you more about daily life than cubic feet does. A 12.4-inch turntable takes a full dinner plate with room for a mug beside it; a 10-inch one takes the plate and nothing else. Cubic feet describes the whole cavity, including the corners a spinning plate never reaches.
Then measure the outside. The cabinet is always wider than the cavity inside it, so a 1.6-cubic-foot oven runs about 22 inches across your counter, and a 2.1-cubic-foot one is wider still. Depth catches people out too: a 16-inch cabinet will not sit on a 12-inch shelf.
What wattage actually buys
Watts turn into minutes. A 1,000-watt oven reheats a plate of leftovers in the time you expect; a 700-watt one needs noticeably longer, and the gap widens with dense food such as a potato or a frozen block. The 950-to-1,200-watt models here also hold up better when the cavity is full.
If you reheat coffee and a pastry, 700 watts is fine and you save money. If you actually cook — defrosting, heating through, cooking vegetables — buy 1,000 watts or more and accept the extra width and weight that comes with it.
Sensor cooking versus preset menus
A humidity sensor is the difference between pressing one button and choosing a time, a power level and a stir. It reads the steam coming off the food and stops when the food is done, which is why it can handle a bowl of rice and a plate of chicken without any input from you.
Preset menus work differently: popcorn, pizza, potato and beverage keys simply apply a stored time to a category. Both are useful, and the presets are quicker to learn, but the sensor is the feature worth paying for if reheating leftovers is most of what the oven does.
Doors, keypads and child locks
A push-button release lets you open the oven with one hand or an elbow while the other hand holds a plate; a handle gives you something to grip and pull, which is easier for anyone with sore hands. Neither is better in the abstract, so open both kinds in the store if you can.
Child locks are the hidden friction. On several ovens the door stays latched until you press Stop or release a two-step lock, which turns every reheat into a sequence. Check whether the lock can be switched off before you decide the door is faulty.
Weight, depth and the walk to the counter
A 1.2-cubic-foot oven weighs around 31 pounds; the 2.1-cubic-foot Frigidaire weighs 52. That matters twice — once when you carry it in from the porch, and again when you decide it needs to move six inches to the left.
Decide on the final spot before the box comes through the door, check that the route is clear, and confirm the outlet is where you think it is. A microwave is one of the few kitchen appliances you can buy, unbox and use in ten minutes; a bad spot makes it a chore every day.
Frequently Asked Questions
How long should a countertop microwave last?
Every oven in this group carries a one-year warranty, and the failures that show up tend to be sudden rather than gradual — the oven heats normally and then stops heating altogether. Register the product the day it arrives and keep the receipt somewhere you can find it.
Because the failures are total rather than repairable, the practical protection for years two and three is the extended warranty or a credit card that doubles the manufacturer’s cover. Budget for the replacement rather than the repair.
Can a countertop microwave share an outlet with a coffee maker?
Check the input figure, not the cooking figure. The 1,000-watt models here draw roughly 1,550 to 1,600 watts from the wall while they run, and a kettle or espresso machine pulls a similar amount, so running both on one circuit at once is how breakers trip.
Give the microwave an outlet of its own, or at least one that nothing else is drawing from while it heats. A 700-watt oven is the easier guest on a shared kitchen circuit.
How do I stop the microwave from beeping?
Look for a speaker symbol or a sound button on the keypad. On the COMFEE’ you hold the sound key for about three seconds; the Chefman has a separate audio button; the Toshiba lists a mute function alongside its ECO mode.
If there is no speaker key and holding Stop does nothing, the beep is not defeatable on that model — worth checking before you buy if the kitchen is next to a bedroom.
Final Verdict
The Toshiba EM131A5C is our default because it gets the three things that matter right at once: a 12.4-inch turntable that takes a real dinner plate, 1,000 watts that heat in the time you expect, and a humidity sensor that takes the guesswork out of reheating. Nothing else here balances those as comfortably for the money.
Two situations change the answer. Cooking for four or more, or heating things wider than a plate, makes the 1.6-cubic-foot Toshiba and its 13.6-inch turntable worth the extra width. Working with a narrow strip of counter makes the COMFEE’ the only one that fits.
