Air fryer

An air fryer is a small convection oven. It does the same thing as deep frying but without putting the food in oil.
It is a kind of convection oven (or fan-assisted oven or fan oven). This is an oven which has fans to circulate air around food. This spreads the heat evenly.
Air fryers cook food that would otherwise be cooked in oil. The air fryer's cooking chamber radiates heat from a heating element near the food, and a fan circulates hot air.
The machine does coat the food in a thin layer of hot oil. It does this at 200 °C (392 °F).
