Microwaves are essential appliances used daily in most household kitchens. Today's models are built to do much more than just reheat last night's leftovers. Many microwaves feature cooking presets that can perform a variety of tasks with the touch of a button, like steam fresh vegetables, defrost chicken breasts, melt chocolate, soften butter, and bake potatoes. Some microwaves even have grilling and convection heating capabilities.
Microwaves designed for countertop use are ready to go right out of the box and, since they don't need any installation—they're also easy to move around if needed. They're generally compact enough that you can find a spot for them in the smallest of kitchens, even if it means keeping one stashed on a table or storage cart.
Here's our list of the best countertop microwaves.
Best Overall: Panasonic NN-SN966S Countertop/Built-In Microwave with Inverter Technology
Automatic sensors adjust cooking times and power
Can defrost anything without cooking it
Can be used on a countertop or as a built-in
Too big for compact kitchens
With 2.2 cubic feet of cooking space and 1250 watts of cooking power, this microwave has space to heat food for the family, and the power to get the job done quickly. The turntable is a whopping 16.5 inches in diameter, so it will hold several plates, large serving dishes, or a large casserole.
Proprietary technology heats food evenly while it also speeds up defrosting time, so you’ll have less waiting time, no matter what’s for dinner. The “genius sensor” adjusts the power and cooking time for different foods. The keep-warm feature will hold your food at serving temperature, while not overcooking it, and the delay start lets you prep food, put it in the oven, and start cooking at just the right time so it’s ready for dinner.
Our tester, who's owned a number of other microwaves, says that after zapping a range of foods—from Indian curry to grains to leftovers—she couldn't find any cool spots (areas that don't heat food as evenly as the rest).
There are 14 presets including essentials like popcorn, pizza, soup, oatmeal, pasta, and frozen foods, so everyone in the family can prepare foods without having to guess how long to cook. Ten power levels, along with options for sensor reheating and cooking, round out the functions that make this oven ideal for most households.
Capacity: 2.2 cubic feet | Turntable Diameter: 16.5 inches | Cooking Power: 1250 watts | Dimensions: 14 x 23.9 x 19.4 inches | Warranty: 1 year
"I was able to heat up two plates of leftovers at once so my kids didn’t have to fight over the first plate of piping hot pizza pockets." — Linnea Covington, Product Tester
Best Convection Cooking: Toshiba EC042A5C-SS 1.5 Cu. Ft. Convection Microwave Oven
Can microwave and convection-cook either separately or at the same time
Not as many food presets
Microwave ovens are great for steaming and reheating, but they’re not good at browning foods. This combination microwave and convection oven takes care of that problem. You can microwave or convection-cook the food separately, or you can use them in combination for super-fast cooking and perfect browning at the same time. Many reviewers highlighted this oven's convection performance, with one praising how well it crisped a range of foods, from potatoes to frozen pizzas.
This doesn’t have as many specific food presets, with just popcorn named, but it has buttons for auto bake, auto roast, sensor cook, sensor reheat, auto defrost, timed defrost, and for keeping food warm. You can also set up to three favorite combinations of time and power so your hot chocolate is always perfect and your butter melts just right.
Convection cooking can be set from 170 to 425 degrees and there are 10 microwave power levels using 1000 watts of power.
Capacity: 1.5 cubic feet | Turntable Diameter: 13.6 inches | Cooking Power: 1000 watts | Dimensions: 21.73 x 21.38 x 12.83 inches | Warranty: 1 year
Best Basic: Toshiba EM925A5A-BS 0.9 Cu. Ft. 900-Watt Countertop Microwave
Fits dinner plates
Round turntable might not fit rectangular dishes
This microwave has everything you need for basic tasks, plus a little more. It’s not the largest microwave you’ll find, but it’s not the smallest. It’s great for reheating dinner for one, or steaming frozen broccoli for a side dish. The inside capacity is 0.9 cubic feet, and it has a 10.6-inch diameter turntable that’s large enough for a dinner plate or rounded casserole dish.
This has 900 watts of cooking power, 10 power settings, and a digital control panel. The defrost setting lets you choose a defrosting time or you can enter a weight to let the oven do the thinking. Presets for popcorn, potato, pizza, frozen vegetables, and a dinner plate give you one-button cooking, so you don’t have to guess how long you’ll need to cook those items. If oven beeping annoys you, you can turn off the sound.
Capacity: 0.9 cubic feet | Turntable Diameter: 10.6 inches | Cooking Power: 900 watts | Dimensions: 19.1 x 16.1 x 11.5 inches | Warranty: 1 year
Best Commercial Quality: Panasonic 1000 Watt Commercial Microwave Oven with 10 Programmable Memory NE-1054F
Easy to use and clean
Quick and even heating
If your microwave is constantly working, particularly for reheating single dishes of foods for family members who operate on different schedules, a commercial microwave might be a great choice. This isn’t a huge machine at just 0.8 cubic feet of space, but it is built for quick cooking and long life despite heavy use.
This has 1000 watts of power that it uses efficiently, feeding the energy from the bottom so it travels less than typical microwaves that produce the energy at the top of the cooking chamber. This doesn’t have a turntable, so your cooking space isn’t limited by that disk area and you can fit larger casseroles or arrange more plates and bowls without them tipping or wobbling. Many customers were pleasantly surprised with how quickly and evenly this microwave heated their food despite the lack of turntable.
The keypad includes braille, with 10 buttons that are shortcuts for a variety of cooking times. You can also program multiple-stage cooking, with different times and power levels at each stage.
Since this is designed for commercial use, the design is more stark than friendly, but the stainless steel exterior would blend well with a modern kitchen’s décor.
Capacity: 0.8 cubic feet | Turntable Diameter: N/A | Cooking Power: 1000 watts | Dimensions: 20.125 x 16.5 x 12 inches | Warranty: 1 year
Best with Grill Function: Farberware Black FMO12AHTBSG 1.2 Cu. Ft 1100-Watt Microwave Oven with Grill Function
Microwave and grilling functions can be used separately or together
Some say it gets loud when heating
The grilling function on this microwave sets it apart from the rest of the pack, while its standard microwave functions are everything you’d expect from a quality microwave. It has 1.2 cubic feet of cooking space, 1100 watts of cooking power, a 12.4 inch turntable, and 10 levels of microwave power.
Cooking presets include popcorn, potato, frozen pizza, frozen vegetable, beverage, meat, and dinner plate. You can defrost by time or weight, set your own cooking time and temperature, and set multi-stage cooking to change the cooking power during the cooking time.
The grilling function can be used alone, or in combination with microwave cooking so you can cook quickly while also browning and crisping the food. Several customers raved about how well the grill function worked on a variety of foods, from toast to steaks. A grilling rack is included.
Capacity: 1.2 cubic feet | Turntable Diameter: 12.4 inches | Cooking Power: 1100 watts | Dimensions: 20.5 x 17.3 x 12.8 inches | Warranty: 1 year
Best Design: Nostalgia Retro 0.9 Cubic Foot 800-Watt Countertop Microwave Oven
Bright retro design
Has 12 presets
Easy to operate
Louder than some other microwaves
The retro design of this microwave is just funky enough to look modern at the same time. The vibrant red will add a pop of color while the oval window, digital clock, and round controls evoke an era when space travel was a fantasy. It's also available in aqua, black, and ivory. In a modern kitchen, it would add a note of whimsy. Indeed, several reviewers lauded how much the microwave spruced up their space.
It isn’t all about design, though. This offers 0.9 cubic feet of cooking space and 800 watts of cooking power, a dozen programmed cooking settings for favorites like popcorn, potatoes, pizza, vegetables, and more.
The chosen cooking settings appear on the clock, so the controls are simple, while the LED display makes it easy to read, even if it’s a late-night popcorn snack. This has a rotating glass turntable and should hold plates up to about 11 inches in diameter.
Capacity: 0.9 cubic feet | Turntable Diameter: 11 inches | Cooking Power: 800 watts | Dimensions: 21.65 x 17.9 x 13 inches | Warranty: 6 months
Best for Small Spaces: BLACK+DECKER EM720CB7 0.7 Cu. Ft. Digital Microwave Oven
Powerful for its size
Six Express Heat buttons
Custom memory function
Can’t fit full-size dinner plates
Tough to open door
At just under 1.5 feet wide, this compact model is ideal for smaller spaces. Whether you wish to reheat leftovers in a dorm, coffee at work, or for occasional use in a small apartment kitchen, this 0.7-cubic foot microwave has enough power to handle basic microwave tasks without taking up valuable space.
Instead of a handle, the door is operated with a push button which saves even more space. The glass turntable is round and can be removed to clean spills and splatters.
Our product tester found her 11-inch dinner plates didn't fit inside this microwave. She recommends using smaller, salad-sized plates. As for power, our tester was impressed with how this microwave compared to her more powerful, over-the-range microwave. She found most dishes were sufficiently reheated in the same amount of time despite the small size and lower wattage.
Capacity: 0.7 cubic feet | Turntable Diameter: 10 inches | Cooking Power: 700 watts | Dimensions: 17.3 x 10.2 x 13 inches | Warranty: 1 year
"It easily fits underneath our upper kitchen counters, and there was even room to place items on top of it, which could be handy in small kitchens where space is tight." - Camryn Rabideau, Product Tester
Best Budget: Hamilton Beach 0.9 Cu. Ft. Stainless Steel Microwave Oven
Express cook buttons
Variety of cook functions
Smaller than average
Some limits to one-touch cooking
Concerns about longevity
If you need a microwave for occasional use, there's no need to invest in a model loaded with bells and whistles. This affordable pick has all the standard features you need in a microwave and doesn't take up too much space.
It has express cook settings for 1-6-minute cook times that can be selected by pressing the corresponding digit on the keypad. The start button doubles as a 30 second express setting and power level can be adjusted for tempering chocolate or defrosting meat.
There are basic one-touch button presets for baked potato, popcorn, pizza, beverage, frozen dinner, and reheating. The keypad can also be locked to keep kids from playing with the settings.
Even though this microwave is on the smaller side compared to others on this list, our product tester found she could fit a standard dinner plate on the turntable. just as well as a larger, more expensive, and more powerful over-the-range model. Our tester also noted this model has toned down alerts and beeps much more quietly than other models.
Capacity: 0.9 cubic feet | Turntable Diameter: 10.5 inches | Cooking Power: 900 watts | Dimensions: 17.09 x 14.25 x 22.2 inches | Warranty: 1 year
"The Beverage preset button is particularly useful, as it allows you to choose between 4-, 8-, 12-, and 16-ounce options." - Camryn Rabideau, Product Tester
The Panasonic Microwave Oven NN-SN952S is our top pick thanks to its generous capacity large enough to feed a family. Its turntable can hold several plates and it has a "genius sensor" that auto-adjusts the power level and cooking time for different foods. If you'd like a microwave oven with convection heating capabilities, check out the Toshiba Convection Microwave Oven (view at Amazon). It can be used to microwave cook or convection cook separately or at the same time and is quiet in use.
What to Look for When Buying a Countertop Microwave
External and Internal Dimensions
Countertop microwaves are generally smaller than their built-in counterparts, but make sure you have the counter space for the appliance, or that it will fit in your microwave shelf if you have one.
Microwaves are measured in cubic feet. When measuring where you're storing your microwave, note that countertop microwaves' external dimensions vary, so be exact when you measure that space's width, height, and depth.
Are you cooking for one or for an entire family? Make sure to look at internal capacity. This can measure anywhere from 0.5 cubic feet (the average dinner plate) to 2 cubic feet (larger dish- and cookware) in countertop microwaves.
This refers to cooking power—meaning how quickly and evenly the microwave will cook your food. Most microwaves are typically 1000 watts, but cheaper ones might have less power.
Typically, appliances with 600 watts or less will cook your food more slowly and less evenly. Note, though, that if the microwave has additional functions, such as grilling or convection cooking, those functions might use a higher wattage than the microwave element.
Today's microwaves often offer countless features. Some common ones you might find are power levels, a sensor that adjusts power and cook time depending on the food, presets for specific foods like popcorn, auto-defrost, keep warm, and more. Some even have a child lock feature, or settings that allow you to turn off all sounds.
Can you put a countertop microwave in a cabinet?
Countertop microwaves are not designed to be kept in enclosed spaces, such as a cabinet. Doing so may block the air vents located on the sides, top, or back of a microwave which creates a safety and fire hazard. Blocking the vents may cause a microwave to overheat or malfunction.
If you have enough clearance so that the vents are 3 inches from cabinet walls, it can be done.
If you want to save counter space, your next best option is to look into having an over the range mounted microwave or drawer microwave added to your kitchen.
Can you mount a countertop microwave?
Countertop microwaves do not come with mounting hardware. They are designed to stand on a flat surface, like a countertop or an open shelf. If you're replacing an existing mounted microwave, you should be sure to carefully measure and find a model that fits the opening.
Does a countertop microwave need a dedicated circuit?
A dedicated circuit is an outlet that is used by only one appliance and is linked to its own circuit breaker in your whole house electrical box. Not all microwaves require a dedicated circuit. Built-in and mounted microwaves typically use dedicated circuits because they tend to be larger and have high power ratings. Countertop models tend to be smaller and use less power and can be used in a standard outlet. If you're concerned about safety, it's best to get your electrical setup checked by a certified electrician.
Do countertop microwaves need to be vented?
No. Countertop microwaves are designed to recirculate air through a filter and vent it back into the kitchen. This is why it's important to not block the vents on the sides or back of the microwave.
