Heat is circulated throughout the cooking chamber of an air fryer using a heating element and a fan located at the top of the appliance (either a basket or a grated rack depending on the style.) Although air fryers crisp food similarly to deep fryers, they only use a little amount of cooking oil (1 to 2 teaspoons). In fact, several naturally high-fat meals, including chicken or salmon, can be prepared without using any oil.
However, since liquid batter cannot be cooked in an air fryer, it is preferable to stick with dry components like breadcrumbs or spice. Once your meal has finished cooking for half the suggested time, shake or rotate it for the best crispness.
