They are best served within an hour of air frying, but can be refrigerated in an airtight container or baggy and popped back in the air fryer for just a few minutes to warm through. Try brushing with some warm butter after reheating and they will taste like you just made them! You can also store them in an airtight container on the counter for 1-2 days, but if they are exposed to air, they will start to harden.
