Do not crowd the air fryer basket. You should be able to comfortably fit 4 ears of corn in a regular sized air fryer basket. Work in batches if you are doubling the recipe.
For convenience, you can purchase fresh corn on the cob that has already been husked and had the silks removed.
Whether you cut the corn cobs in half or leave them whole is up to you. It does not change the cook time.
You can use frozen corn instead of fresh if desired. There's no need to thaw the corn cobs first, simply pop them in the air fryer basket, add a bit of oil (optional), and cook at 380F for 13-15 minutes.
