The Breville also makes it simple to customize based on the size, weight, and nature of the food you’re cooking. There’s even a reheat option for pizza. Alternatively, you can leave it up to the Breville’s sensor to detect moisture and temperature and accurately reheat. When we tried this in our testing of beverages and with our own lunches, it was surprisingly accurate.

For convenience in the kitchen, nothing beats the microwave, which allows you to cook and reheat food from the inside out. After more than 100 hours of research and testing, we think that the Toshiba EM925A5A-BS is the best microwave for most kitchen counters. It’s easy to operate, has a number of express cooking options that heat food quickly and evenly, and even has a mute button so you can cook in silence.
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.)
If you’re worried about standing too close to your microwave and absorbing radiation, don’t be. The level of radiation in microwave ovens is very low, and must comply with strict regulations put in place by the FDA. You can read a detailed explanation in this article from The New York Times (parent company of Wirecutter). And no, for the most part, the radiation in microwaves won’t destroy the nutrients in your food.

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.”
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).

The development of the cavity magnetron made possible the production of electromagnetic waves of a small enough wavelength (microwaves). American engineer Percy Spencer is generally credited with inventing the modern microwave oven after World War II from radar technology developed during the war. Named the "Radarange", it was first sold in 1946. Raytheon later licensed its patents for a home-use microwave oven that was first introduced by Tappan in 1955, but these units were still too large and expensive for general home use. Sharp Corporation introduced the first microwave oven with a turntable between 1964 and 1966. The countertop microwave oven was first introduced in 1967 by the Amana Corporation. After Sharp introduced low-cost microwave ovens affordable for residential use in the late 1970s, their use spread into commercial and residential kitchens around the world. In addition to their use in cooking food, microwave ovens are used for heating in many industrial processes.
