Food and cookware taken out of a microwave oven are rarely much hotter than 100 °C (212 °F). Cookware used in a microwave oven is often much cooler than the food because the cookware is transparent to microwaves; the microwaves heat the food directly and the cookware is indirectly heated by the food. Food and cookware from a conventional oven, on the other hand, are the same temperature as the rest of the oven; a typical cooking temperature is 180 °C (356 °F). That means that conventional stoves and ovens can cause more serious burns.

This GE microwave oven with a 16-inch turntable proves you don't need to spend a bundle to get perfectly "baked" potatoes, steamed broccoli, or evenly heated mac 'n cheese. Thanks to a smooth control panel with lettering that contrasts well with the background, it's super easy to read the display and wipe it clean. If stainless steel isn't your style, this model also comes in black and white.

For our 2018 update, we ran a series of tests on 12 microwaves. First, we created our own version of a heat map by cutting a piece of parchment paper to fit the turntable of each model and completely covering it with a layer of plain mini marshmallows. Then we nuked it on high for 2 minutes until the marshmallows began to brown. By looking at the underside of each piece of parchment paper, we could see the pattern of browning and determine how evenly the microwaves generated heat (for more on how microwaves work, see above).

There are two types of microwave vent systems: recirculating and external. Recirculating vents simply pull the air up into the appliance, run it through a filter to remove impurities, then push it back out into your kitchen. This type of ventilation system is ductless and easier to install, but it doesn’t perform as efficiently as external ventilation. 


Toshiba makes microwaves in other sizes too: 1.2, 1.5, and 1.6 cubic foot, all of which have slightly different internal parts and control panels. However, after testing the 0.9 and 1.2 cubic foot models for this guide, we think the former is the best for most people because it’s simpler to use and takes up less space. You can’t fit a 9-by-13-inch casserole dish in the cavity of the 0.9-cubic-foot unit, but its 10.5-inch turntable is still wide enough to fit an 11-inch dinner plate or a 9-inch square casserole dish. At 900 watts, the 0.9-cubic-foot Toshiba also packs a lot of power for its size. It measures 19.1 by 16.1 by 11.5 inches, so it’s a nice midsize option that falls in between the two other microwaves we recommend. And while we realize the control panel looks straight out of the ’90s, the microwave is available in a stainless steel or black stainless steel exterior, so it will fit the aesthetic of most kitchens.

There are three main styles of microwaves, and they’re distinguished predominantly by where and how they’re installed. First, there are your standard countertop microwaves, which simply sit on the kitchen counter and are plugged into an electrical outlet. This style is often the least expensive and works best for anyone who lives in a rented home, as they can be moved easily. Countertop microwaves are also a good option if you don’t want to remodel your kitchen to accommodate a built-in style. 
Over-the-range microwaves give you the convenience of quick reheating without sacrificing counter space. This 1.9-cubic-foot model from Whirlpool is available in multiple colors and finishes, including fingerprint-resistant stainless steel. Featuring 1,000 watts of power, it's also equipped with a 300 CFM ventilation system to keep odors and smoke from your cooktop under control. Customers particularly love the inclusion of the three-speed fan. Reviewers found installation to be fairly straightforward, but some noted that the instructions for all the settings aren't very clear.
To find the best microwave, we tested 10 microwaves in our Kitchen Appliances and Technology Lab, checking how well they melted cheese, "baked" potatoes, reheated food, defrosted frozen food, popped popcorn, and cooked vegetables. We also looked at their ease of use — controls, opening the doors, view-ability inside, cooking alerts, and cleaning. For models with convection and/or grill capabilities, we tested their ability to roast chicken, bake cake, and broil steak, then noted the surface temperatures. Based on our extensive tests, we've rounded up our top-rated microwaves:
If you need a new oven range microwave, then it needs to have the right features for your oven setup. Not only does it need to fit in the same space, but it also needs to handle the same (if any) venting capabilities. Our GE pick is a great option because it can fit in many different types of kitchens, but you need to match features to your requirements.
Modern microwave ovens use either an analog dial-type timer or a digital control panel for operation. Control panels feature an LED, liquid crystal or vacuum fluorescent display, in the 90s brands such as Panasonic and GE began offering models with a scrolling-text display showing cooking instructions, numeric buttons for entering the cook time, a power level selection feature and other possible functions such as a defrost setting and pre-programmed settings for different food types, such as meat, fish, poultry, vegetables, frozen vegetables, frozen dinners, and popcorn.
The included turntable is easy to remove for cleaning, and the large programming screen allows you to specify power levels, cooking times, and menu options for shortcuts and more complex cooking tasks. If you aren’t a fan of all those automatic options, then there are an amazing 14 auto-cook options for menu buttons that can cook a specific kind of food. Even the start button stands out and is easy to use.

Since this model is particularly affordable, this is a good time to mention that prices can fluctuate based on inventory and other factors. We can’t necessarily guarantee that our listed prices are the rule of law. The good news here is that they may drop and save you even more money! But this Toshiba model still remains one of the most affordable picks we found of the bunch.
The lower temperature of cooking (the boiling point of water) is a significant safety benefit compared to baking in the oven or frying, because it eliminates the formation of tars and char, which are carcinogenic.[49] Microwave radiation also penetrates deeper than direct heat, so that the food is heated by its own internal water content. In contrast, direct heat can burn the surface while the inside is still cold. Pre-heating the food in a microwave oven before putting it into the grill or pan reduces the time needed to heat up the food and reduces the formation of carcinogenic char. Unlike frying and baking, microwaving does not produce acrylamide in potatoes,[50] however unlike deep-frying, it is of only limited effectiveness in reducing glycoalkaloid (i.e., solanine) levels.[51] Acrylamide has been found in other microwaved products like popcorn.
Consumer household microwaves usually come with a cooking power of 600 watts and up, with 1000 or 1200 watts on some models. The size of household microwaves can vary, but usually have an internal volume of around 20 liters (1,200 cu in; 0.71 cu ft), and external dimensions of approximately 45–60 cm (1 ft 6 in–2 ft 0 in) wide, 35–40 cm (1 ft 2 in–1 ft 4 in) deep and 25–35 cm (9.8 in–1 ft 1.8 in) tall.
The best size microwave for you will depend on how much space you have available and how much food you'll need to heat up at a time. If your space is limited or you're only heating food for one person, a 0.5 cubic-foot model may be a good choice. If you're furnishing a gourmet kitchen, you may want a 2.5 cubic-foot combination microwave-convection oven.

The Breville’s accuracy and customizability were unmatched in testing. Because microwave heat conducts from the outside in, you’ll usually get rubbery edges if you don’t lower power to allow the heat to seep in further. But with the Breville, if something starts boiling over, you can use its power level and time dials in the midst of cooking and let the heat penetrate.
Like the 0.9-cubic-foot model, this Toshiba has one-touch start buttons from 1 to 6 minutes, a plus-30-seconds button, and a child-lock function. This model also shares several other features with the smaller Toshiba, such as a memory function and a multistage cooking function—but, realistically, we don’t think most people will use these controls often.

Reviewers can’t contain their delight about this microwave’s Genius Sensor, which automatically adjusts the time and power based on the food type. “It feels very futuristic to press the Sensor Heat and let the microwave figure out on its own how long it should cook for. Most of the time, it’s dead-on, too, which is nice,” praises one commenter. “It’s pretty much impossible to overcook something,” writes another. Others note they “have had nothing boil over” and it “cooks super evenly. The days of half-molten-half-frozen food are gone.” Its modern exterior is another strong selling point. “The stainless steel looks very sleek and nice and will fit in with most kitchens,” one says.
If you want a smaller microwave that still offers plenty of power, then this 1.1-cubic-feet, 1000-watt option from Samsung is a great pick. Customers love the modern black color scheme and the brushed stainless steel handle. The design of the control panel is also unique because it combines digital controls with a metal dial. The ceramic enamel interior is designed to wipe clean easily and resist grease, oil, and scratches. Online reviewers appreciate the unique LED display and say that one of the microwave's highlights is Eco mode, which allows you to turn the digital display off to conserve energy. One downside is that the microwave can be quite loud, according to current owners.

Wattage is not only about size, but also about how powerful the microwave is. If your microwave has 1,000 watts of power or more, it’s going to be very effective at heating. If it has a lower wattage, you may need to temper your expectations: the best way to microwave a potato, for example, may vary based on wattage, especially if you’re making a big change from your old model to the new one.
Microwave ovens heat food without getting hot themselves. Taking a pot off a stove, unless it is an induction cooktop, leaves a potentially dangerous heating element or trivet that will stay hot for some time. Likewise, when taking a casserole out of a conventional oven, one's arms are exposed to the very hot walls of the oven. A microwave oven does not pose this problem.

Uneven heating in microwaved food can be partly due to the uneven distribution of microwave energy inside the oven, and partly due to the different rates of energy absorption in different parts of the food. The first problem is reduced by a stirrer, a type of fan that reflects microwave energy to different parts of the oven as it rotates, or by a turntable or carousel that turns the food; turntables, however, may still leave spots, such as the center of the oven, which receive uneven energy distribution. The location of dead spots and hot spots in a microwave can be mapped out by placing a damp piece of thermal paper in the oven. When the water saturated paper is subjected to the microwave radiation it becomes hot enough to cause the dye to be released which will provide a visual representation of the microwaves. If multiple layers of paper are constructed in the oven with a sufficient distance between them a three-dimensional map can be created. Many store receipts are printed on thermal paper which allows this to be easily done at home.[40]
A new microwave can provide extra options that you may not have not – including sensors for more accurate cooking times, inverter technology that creates more accurate power levels, and customized cooking menus for the food you love. If you do a lot of cooking, a modern microwave can also serve as an able assistance, with programmable defrosting, butter melting, and warm-up functions that make your cooking projects that much easier. One of these new models may also provide faster cooking times, child locks for great safety, and more consistent cooking/thawing for a variety of foods.

One touch buttons take care of all the work for you. We particularly like the buttons that combine sensors with a preprogrammed cooking time to automatically adjust based on the food you put inside the microwave. One touch buttons for common foods like popcorn, potatoes, hot dogs and more are also a plus – as are time-saving buttons for immediate reheating, melting, defrosting, and so on.
Microwaves come with a slew of cooking functions, but Franke told us, “There are so many features on microwave ovens and people just don’t use them. And I’ll admit that I use the minute-plus feature on mine more than anything else.” Though other cooking functions may not get used frequently, we still put them through their paces on the models we tested.

The Toshiba has an easy-to-use digital interface, with one key feature that helps it stand out from much of the competition: a mute button. Since this model doesn’t stop beeping when you open the door, we appreciated having the option to mute the beeping entirely. The Toshiba also has six preset cooking functions for popcorn, potatoes, pizza, frozen vegetables, beverages, and reheating a dinner plate. It has one-touch start controls from 1 to 6 minutes, and a plus-30-seconds button so you can quickly add extra time. Also, its lock function prevents kids from accidentally operating the machine (you simply hold the stop/cancel button for 3 seconds to lock or unlock the door). This model also has several other features that other microwaves we tested lacked, including a memory function (that saves up to three customized cooking times and power levels) and a multistage cooking function (that allows you to set two different cooking times and power levels to operate in succession), but we don’t think most people will use these often.

For years, there wasn't much innovation in microwave technology — that is, up until Amazon introduced its own AmazonBasics microwave that works with Alexa. Now, you can use your voice to command your appliance to heat foods and the built-in tech will know exactly how long and at what power level to use. It's also the most affordable microwave you can buy.
In 1947, Raytheon built the "Radarange", the first commercially available microwave oven.[13] It was almost 1.8 metres (5 ft 11 in) tall, weighed 340 kilograms (750 lb) and cost about US$5,000 ($56,000 in 2018 dollars) each. It consumed 3 kilowatts, about three times as much as today's microwave ovens, and was water-cooled. The name was the winning entry in an employee contest.[14] An early Radarange was installed (and remains) in the galley of the nuclear-powered passenger/cargo ship NS Savannah. An early commercial model introduced in 1954 consumed 1.6 kilowatts and sold for US$2,000 to US$3,000 ($19,000 to $28,000 in 2018 dollars). Raytheon licensed its technology to the Tappan Stove company of Mansfield, Ohio in 1952.[15] They tried to market a large 220 volt wall unit as a home microwave oven in 1955 for a price of US$1,295 ($12,000 in 2018 dollars), but it did not sell well.
