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.
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.
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.
For most people, microwaves are a must-have kitchen appliance for meal prep. Whether you want to popcorn or a warm bowl of soup, a microwave will get the job done in mere minutes. Plus, there's nothing to preheat, which helps you conserve energy in your home. Their convenience and ease of use are what make microwaves a staple for most modern households.
In our heat map test, the Toshiba produced the most even heating pattern of all the microwaves we tested, perfectly browning the layer of marshmallows from edge to edge. It expertly cooked a baked potato in about 6 minutes, which was average for the microwaves we tried. It also reheated beverages well and perfectly cooked frozen macaroni and cheese. And it made tasty popcorn, with only 5 grams of kernels left unpopped, which was on a par with most of the models we tested. This model allows you to defrost by time or weight, but like most of the microwaves we tested, it didn’t defrost meat well.
A microwave oven (commonly referred to as a microwave) is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. This induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating. Microwave ovens heat foods quickly and efficiently because excitation is fairly uniform in the outer 25–38 mm (1–1.5 inches) of a homogeneous, high water content food item.
