An air fryer is a type of small convection oven designed to simulate deep frying without submerging the food in oil. An air fryer works by circulating hot air at high speeds, producing a crispy brown layer on the food being cooked.

While the taste of air fried food is not identical to traditionally deep fried foods, it is generally considered a "close enough" healthier alternative to deep frying. A key difference in flavor comes from oil penetrating the food in traditional deep frying, which adds flavor, while air fried foods are merely covered in a wet batter before cooking.
