Different microwaves are designed for different locations. A countertop microwave sits on top of your kitchen counter. An under-cabinet microwave is mounted beneath your drawers-cabinet-organizers/4044_623679_1032619_1075864'>kitchen cabinets, keeping your counter space clear. An over-the-range microwave is mounted over a range or stove. Microwaves of this type often have built-in exhaust fans and lights.
Of course, once you buy your favorite microwave model, you need to start thinking about what to put inside it! Fortunately, we can help there, too. We’ve also got answers if you’re wondering if styrofoam is microwave safe – or are trying to find the best microwave popcorn for movie night (even low-calorie options). You can also keep up with latest microwave inventions out there, like Samsung’s healthy frying microwave!
The 1.2-cubic-foot Toshiba didn’t heat as evenly as the smaller Toshiba. Unlike the 0.9-cubic-foot version, this Toshiba uses a steam and temperature sensor to automatically determine cooking time. However, we didn’t find the sensor particularly accurate: The baked potato we cooked using it came out completely raw in the center. In our heat map test, the marshmallows near the center of the turntable came out very dark. That said, it heated more evenly across the surface of the turntable than most of the microwaves we tested. The popcorn we made wasn’t burned, though it did have twice as many unpopped kernels as the 0.9-cubic-foot model. We liked that this model beeps to prompt you to flip meat while defrosting, something the smaller one doesn’t do. Impressively, this Toshiba only slightly cooked the edges of ground beef on the defrost mode, unlike most of the models we tested, which fully cooked entire sections of meat.
Water and other homogeneous liquids can superheat[54][55] when heated in a microwave oven in a container with a smooth surface. That is, the liquid reaches a temperature slightly above its normal boiling point without bubbles of vapour forming inside the liquid. The boiling process can start explosively when the liquid is disturbed, such as when the user takes hold of the container to remove it from the oven or while adding solid ingredients such as powdered creamer or sugar. This can result in spontaneous boiling (nucleation) which may be violent enough to eject the boiling liquid from the container and cause severe scalding.[56]
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.
We wanted to find microwaves that could cook a variety of foods, including frozen meals, popcorn, and whole potatoes, quickly and evenly. Some models have functions that cook food using preprogrammed time and power level settings. Others use built-in sensors that automatically adjust the cooking time based on the amount of steam emanating from the food. But regardless of the technology used, none of the microwaves we tested were perfect. Some microwaves had a more accurate baked-potato setting, while others were better at defrosting ground beef. We’d recommend choosing a microwave that excels at cooking the food you plan to prepare most often.
Like most microwaves we tested, the Toshiba wasn’t great at defrosting meat. This model doesn’t beep to remind you to flip the meat halfway through heating, so if you forget, the results are pretty unappetizing. The ground beef we attempted to defrost in this Toshiba remained partially frozen in the center, while the edges were slightly cooked. For that reason, we don’t ever recommend using a microwave for defrosting meat unless you absolutely have to. It’s always best to thaw meat in the fridge or under cold running water. That said, we still think the defrost mode is great for quickly thawing frozen bread or bagels.
Microwave ovens are frequently used for reheating leftover food, and bacterial contamination may not be repressed if the safe temperature is not reached, resulting in foodborne illness, as with all inadequate reheating methods. While microwaves can destroy bacteria as well as conventional ovens, they do not cook as evenly, leading to an increased risk that parts of the food will not reach recommended temperatures.[72]
Not Measuring Before You Buy: We can not reiterate this enough: always measure and compare your space with the dimensions of the microwave you plan to buy beforehand. This is absolutely necessary if you have a cabinet or space specifically for a microwave, but it’s also important if you are buying a counter microwave. The best cheap microwave in the world isn’t going to you much good if it doesn’t fit in that corner when you’re short of kitchen space.

The Toshiba microwave is covered by a one-year warranty, and the claims process is better than what most manufacturers offer. Typically they require you to ship the unit to and from a service center at your own cost, which likely costs as much as or more than the microwave itself. If anything should go wrong with the microwave under warranty, Toshiba will not repair the unit. Instead, they’ll issue you a refund check, which, according to the representative we spoke to, can take anywhere from four to eight weeks. Just know that you’ll need to provide your original receipt, the cut power cord from your unit, and the model number label in order to receive the refund. Contact Toshiba’s customer support center for more information.
Frequently used microwaves need to be cleaned at least once per week, because any food remnants stuck to the walls can get overheated and cause damage to the microwave itself. A simple trick (courtesy of Wirecutter deputy editor Christine Cyr Clisset) is to nuke a bowl of water for a few minutes on high: The steam will loosen most gunk, and you can wipe it out with just a plain paper towel or a sponge. For cleaning the outside of a microwave, Good Housekeeping recommends spraying cleaner onto a towel and not on the actual surface, where it can get into the perforations and damage the internal elements.

That is, the liquid reaches a temperature slightly above its normal boiling point without bubbles of vapour forming inside the liquid. The boiling process can start explosively when the liquid is disturbed, such as when the user takes hold of the container to remove it from the oven or while adding solid ingredients such as powdered creamer or sugar. This can result in spontaneous boiling (nucleation) which may be violent enough to eject the boiling liquid from the container and cause severe scalding.[56]
Over the range microwaves are a different sort of beast – they typically have extra features like air flow fans underneath their base (used to clear smoke off stoves, which can add to the cost) and tend to be larger than other options. With 300 CFM of air flow and two speed fan controls, this GE model can handle over the range tasks as necessary. That spacious 1.6 cubic ft countertop microwave is also great for larger dishes.
Spinach retains nearly all its folate when cooked in a microwave; in comparison, it loses about 77% when boiled, leaching out nutrients. Bacon cooked by microwave has significantly lower levels of carcinogenic nitrosamines than conventionally cooked bacon.[44] Steamed vegetables tend to maintain more nutrients when microwaved than when cooked on a stovetop.[44] Microwave blanching is 3–4 times more effective than boiled water blanching in the retaining of the water-soluble vitamins folic acid, thiamin and riboflavin, with the exception of ascorbic acid, of which 28.8% is lost (vs. 16% with boiled water blanching).[47]
If you’re looking for a traditional microwave that won’t disappoint, this is our recommendation. It’s standard in visual design, and its 1.1 cubic feet internal capacity strikes a nice balance between conserving space and still fitting a reasonable amount of food. It won’t be the centerpiece of your kitchen; rather, it will simply blend in and do its job reliably well.
Microwaves generated in microwave ovens cease to exist once the electrical power is turned off. They do not remain in the food when the power is turned off, any more than light from an electric lamp remains in the walls and furnishings of a room when the lamp is turned off. They do not make the food or the oven radioactive. Compared to conventional cooking, the nutritional content of some foods may be altered differently, but generally in a positive way by preserving more micronutrients - see above. There is no indication of detrimental health issues associated with microwaved food.[66]

It still offers excellent capabilities like nine different menu buttons for specific foods, but the design makes things easy without the need to learn any new controls. The model also sports an interior, Teflon-like finish called EasyClean, which is designed to allow you to wipe down spills easily (although if you are wondering how to clean a microwave that’s truly dirty, we’ve got some more detailed information for you). The model also comes in both standard and black stainless steel, although the black stainless version is a little more expensive, so you may lose out on the excellent cost savings that come with this Kenmore if you go for that option instead. It has 10 power settings.
This 0.7-cubic-foot Hamilton Beach model performs well enough to earn plenty of rave reviews, despite its budget-friendly price. Reviewers love how well it works and the full set of features it offers, in addition to its small footprint. The microwave features six preset settings to quickly cook popcorn, pizza, frozen veggies, and more. Its 700 watts of power is enough to cook frozen dinners and heat beverages but can take longer compared to more robust microwaves. The microwave can fit a 10.5-inch dinner plate, but some customers felt that the small interior was limiting. A few also complained that the light in the microwave stopped working after a few months.
The microwave frequencies used in microwave ovens are chosen based on regulatory and cost constraints. The first is that they should be in one of the industrial, scientific, and medical (ISM) frequency bands set aside for unlicensed purposes. For household purposes, 2.45 GHz has the advantage over 915 MHz in that 915 MHz is only an ISM band in some countries (ITU Region 2) while 2.45 GHz is available worldwide.[citation needed] Three additional ISM bands exist in the microwave frequencies, but are not used for microwave cooking. Two of them are centered on 5.8 GHz and 24.125 GHz, but are not used for microwave cooking because of the very high cost of power generation at these frequencies.[citation needed] The third, centered on 433.92 MHz, is a narrow band that would require expensive equipment to generate sufficient power without creating interference outside the band, and is only available in some countries.[citation needed]
The Toshiba EM131A5C-BS is best for anyone seeking out a slightly bigger, more powerful 1,100-watt microwave. It looks similar to our main pick, the Toshiba EM925A5A-BS, but offers a few more express controls for specific tasks like cooking bacon, defrosting frozen muffins, and making oatmeal. It also has a Soften/Melt button for butter, chocolate, cheese, and marshmallows. However, we found these additional controls less intuitive to operate than what our other pick offers, and we don’t think they’ll get used often. This Toshiba also boasts a cooking sensor that’s supposed to automatically determine when your pizza or potato is hot enough, but it didn’t perform any better than the 0.9-cubic-foot Toshiba, which lacks this feature. The 1.2-cubic-foot Toshiba has a larger 12-inch turntable, so it will fit most dinner plates and a 9-inch square casserole dish. Like our main pick, this model is available in a stainless steel or black stainless steel exterior.

You’ve probably heard of a convection oven, but did you know that there are convection microwaves, too? These specialty appliances use the same technology as their oven counterparts: A fan blows and circulates hot air into the microwave, helping to cook food faster and more evenly. Convection microwaves can also brown or crisp food, similar to a traditional oven. 
Countertop microwaves are some of the most popular models, and there are many options to choose from. They are quick and easy to install—just plug them in—and you can move them around as needed, making them a top choice for renters. The main downside of countertop microwaves is that they take up valuable counter space, which can be frustrating if you have a small kitchen. 

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.
The most shocking revelation in all of our research was the fact that among the hundreds of microwaves for sale today, many have completely identical hardware. Like, exactly the same—except for slightly different keypads and brand-name badges. This is because most of the microwaves in the world are produced by only a handful of manufacturers. But we also learned that even if the housing looks exactly the same, the way the models are programmed can still make a big difference in performance between seemingly identical microwaves.
Aside from the 10 power levels that this microwave offers, the most impressive feature of the Breville Quick Touch is the Sensor IQ function that automatically adjusts the cooking time for your food — meaning your microwave automatically measures the humidity that's being released from the food you’re reheating or heating, and calculates the cook time.
^ "Efficient" here meaning more energy is deposited, not necessarily that the temperature rises more, because the latter also is a function of the specific heat capacity, which is often less than water for most substances. For a practical example, milk heats slightly faster than water in a microwave oven, but only because milk solids have less heat capacity than the water they replace.[citation needed]
Microwave ovens come in a variety of styles to fit all your home decor needs. It doesn’t matter if we are talking about otr microwaves or countertop microwaves. Some are black stainless steel, others are shiny stainless steel finish for the modern kitchen. If you have retro decor, there is also a retro microwave for you. Many people prefer a stainless steel exterior. It is easy to find the right model that blends right into your kitchen and matches your, espresso machines, food processors, coffee makers, air fryers and other appliances. Many of today’s models can even work with other smart home devices if your home is a smart home.
When you add in the competent wattage and the internal space, which is large enough for the bigger plates in your home, it’s tough to see what this Panasonic model doesn’t do right. This 2.2 cu ft microwave is a winner. Even the design is pleasantly modern and easy to clean in case of grease or stains. This microwave really does impress on every level…but it’s not an over the range model, which may limit your options.

Updates writer Eleanor Ford has used a secondhand Toshiba EM925A5A-BS for about seven months now. Even with the previous life of this microwave, our pick has lived up to its reputation. “It’s never failed to do what I expect a microwave to do, heats evenly, doesn't scorch, and is significantly more quiet than any other microwave I’ve used (including my parents’),” Eleanor said. They also noted that the small size allows the microwave to sit on a shelf rather than take up valuable counter space. Eleanor also said that the only notable downside is that they find it difficult to locate the kitchen timer button.
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.

Another misconception is that microwave ovens cook food "from the inside out", meaning from the center of the entire mass of food outwards. This idea arises from heating behavior seen if an absorbent layer of water lies beneath a less absorbent drier layer at the surface of a food; in this case, the deposition of heat energy inside a food can exceed that on its surface. This can also occur if the inner layer has a lower heat capacity than the outer layer causing it to reach a higher temperature, or even if the inner layer is more thermally conductive than the outer layer making it feel hotter despite having a lower temperature. In most cases, however, with uniformly structured or reasonably homogenous food item, microwaves are absorbed in the outer layers of the item at a similar level to that of the inner layers. Depending on water content, the depth of initial heat deposition may be several centimetres or more with microwave ovens, in contrast to broiling/grilling (infrared) or convection heating—methods which deposit heat thinly at the food surface. Penetration depth of microwaves is dependent on food composition and the frequency, with lower microwave frequencies (longer wavelengths) penetrating further.[citation needed]
