Aluminium foil & stainless steel are safe in an air fryer, but these materials aren’t

Air fryers use circulating hot air, unlike microwaves, for cooking food. Certain materials like plastic and Styrofoam should never go inside the appliance. Oven-safe glass, ceramic, and stainless steel are generally safe for air fryer use. Aluminium foil and parchment paper can be used but require food to hold them down. Proper material selection ensures efficient cooking and prevents safety hazards.
