An air fryer is a frying machine that uses heat to fry food, instead of oil and fat. The air fryer works in a similar way to a convection oven and is used to fry, roast and grill foods.
Air fryers are used to make a variety of dishes, including fried chicken wings, French fries and grilled cheese sandwiches. Many fried dishes are made by simply drizzling or coating ingredients in oil and placing them in the air fryer.
Serious Eats recommends making French fries by soaking uncooked fries in water, drying them, cooking them at a lower level, and then browning them on a higher heat.
