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.
Here at the Strategist, we like to think of ourselves as crazy (in the good way) about the stuff we buy, but as much as we’d like to, we can’t try everything. Which is why we have People’s Choice, in which we find the best-reviewed products and single out the most convincing ones. (You can learn more about our rating system and how we pick each item here.)
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 GE JES1656SRSS used to be our main pick, but has been discontinued. Its replacement, the new GE JES1657SMSS, did well in our tests overall. However, we found that at 1.6 cubic foot, it’s too big for most things you’re ever likely to cook or reheat in a microwave. That said, this model would be a good option for anyone wanting a unit large enough to fit a 9-by-13-inch casserole dish. Like most microwaves we tested, it didn’t defrost meat well, and it lacks a control to silence the beeping.
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.

Next, we tried defrosting a 1-pound portion of frozen ground beef in each microwave, using the automatic defrost setting on the models that had this feature. Some units gave prompts to flip the meat, which we did. When the time was up, we broke apart each block of meat with a fork to see if it was completely defrosted. None of the microwaves were particularly great at this task. Every model at least slightly cooked the edges of the ground beef we attempted to defrost. (Best practice is to slowly thaw meat in the fridge, or relatively quickly under cold running water.)
Though some reviewers found the dial control on this Panasonic microwave “odd” at first, many others think it’s more convenient and easier to use than a keypad. “If you haven’t used a microwave with a simple dial to control the time, try one, you’ll never go back,” raves one reviewer. “The controls are super simple (because of the dial!).” And dozens of reviewers agree that this microwave does its job exceptionally. “This is the best microwave I have owned,” a satisfied customer says. “It feels like this microwave is more responsive to my food and not just zapping it. The lighting on the inside makes it a little harder to see the contents inside, but really, except to assure that something is spilling over the side of the container, it isn’t necessary to see through the door. It has many, many presets for both frozen, reheat, milk, coffee, almost everything that put into a microwave.”
Power settings are commonly implemented, not by actually varying the effect, but by repeatedly turning the power off and on. The highest setting thus represents continuous power. Defrost might represent power for two seconds followed by no power for five seconds. An audible warning such as a bell or a beeper is usually present to indicate that cooking has completed.
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.
A great microwave oven can cook food and heat food. Think: Not just popcorn and leftovers, but steamed veggies, like spaghetti squash, “baked” potatoes, and crispy bacon that’ll rival the cooking results you get from your range — not to mention it’ll do it two to five times faster. Plus, once you learn how to poach eggs in the microwave, you might also finally stop trying to learn how to the old-fashioned way.

Any form of cooking will destroy some nutrients in food, but the key variables are how much water is used in the cooking, how long the food is cooked, and at what temperature.[44] Nutrients are primarily lost by leaching into cooking water, which tends to make microwave cooking healthier, given the shorter cooking times it requires.[45] Like other heating methods, microwaving converts vitamin B12 from an active to inactive form; the amount of conversion depends on the temperature reached, as well as the cooking time. Boiled food reaches a maximum of 100 °C (212 °F) (the boiling point of water), whereas microwaved food can get locally hotter than this, leading to faster breakdown of vitamin B12. The higher rate of loss is partially offset by the shorter cooking times required.[46]
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.

A microwave oven heats food by passing microwave radiation through it. Microwaves are a form of non-ionizing electromagnetic radiation with a frequency in the so-called Microwave Region (300 MHz to 300 GHz). Microwave ovens use frequencies in one of the ISM (industrial, scientific, medical) bands, which are otherwise used for communication amongst devices that don't need a license to operate, so they do not interfere with other vital radio services.

In the 1960s,[specify] Litton bought Studebaker's Franklin Manufacturing assets, which had been manufacturing magnetrons and building and selling microwave ovens similar to the Radarange. Litton then developed a new configuration of the microwave: the short, wide shape that is now common. The magnetron feed was also unique. This resulted in an oven that could survive a no-load condition: an empty microwave oven where there is nothing to absorb the microwaves. The new oven was shown at a trade show in Chicago,[citation needed] and helped begin a rapid growth of the market for home microwave ovens. Sales volume of 40,000 units for the U.S. industry in 1970 grew to one million by 1975. Market penetration was faster in Japan, due to a re-engineered magnetron allowing for less expensive units. Several other companies joined in the market, and for a time most systems were built by defense contractors, who were most familiar with the magnetron. Litton was particularly well known in the restaurant business.
