An air fryer works like a mini convection oven. A heating element heats the cooking compartment while the fan circulates hot air, surrounding the food on all sides with even heat. If you think about it, the method of cooking in an air fryer is very similar to a deep fryer; an even heat source cooks the food from all sides but allows you to cook without immersing your food in oil. Almost any food you can think of can be cooked in an air fryer. Meats, vegetables, frozen foods, and just about anything else you can think of. You can even put bread in your air fryer to make toast or sandwiches. The bread comes out crusty and not soggy so it makes an excellent grilled cheese sandwich. Because you are cooking with hot air your food might dry out a little so keep that in mind when cooking.
