Air-fryers are having a moment now, which is unsurprising given their promise of crispy fries without vats of oil. This one by Big Boss is currently 32 percent off, or $68. It cooks your food—even frozen, unthawed food—using three techniques: a halogen lamp, convection, and infrared. This fryer can hold 16 quarts of food and has two trays for making two foods at the same time. Unlike other oil-less fryers, the Big Boss comes with icons on top to make sure you're cooking various foods at the correct temperature.
