Not all Air Fryers are created equal. Air Fryers work by circulating hot air around the food. The internal shape of the Air Fryer and how the air flows, as well as how hot the air is all contribute to how long it takes to cook a food. This is why you should check often and only use temperatures as a guide until you know how your particular Air Fryer cooks. Many of the cooking times on this site were tested using a Philips XL Air Fryer.
