Frozen Corn on the Cob in an Air Fryer

Doneness

Kernels are bright deep yellow with a few flecks of golden-brown char from the convection; cob is hot all the way through when pierced; kernels pop crisply when a fingernail catches one (no chewy raw-frozen texture remains).

Technique

Add cobs straight from the freezer, no thaw, no wrap. Arrange parallel in a single layer with at least ½ inch between each so the convection air can rotate around all sides. Flip at 7 minutes — convection alone does not brown the underside of a horizontally-placed cob, so the flip is non-negotiable. Butter and season the moment they come out.

Oil & seasoning

None during the cook — the frost on the kernels would spit if oiled. Brush with melted butter the moment the cobs come out (butter sticks to hot surface kernels in a way it never does to a cold cob).

Watch out for

• !Do not wrap in foil. Foil traps steam and turns the cob into a boiled cob — defeats the entire point of using the air fryer over boiling water. Naked-on-the-rack is the method.
• !Do not thaw. Thawed frozen corn is waterlogged and the kernels slough off the cob during cooking. Frozen-to-basket keeps the kernels attached.
• !Half-cobs (4-5 inches) cook in the times above. Whole cobs (8-9 inches) need 2 extra minutes and must be confirmed to fit your basket diagonally before starting — some basket fryers cannot accommodate a whole cob.
• !Salt only at the end, after the butter. Pre-salting a frozen cob does nothing useful — the salt slides off the surface ice into the drip tray.
