If you aren't careful, it's very easy to end up with dry chicken breasts. Time your cooking time carefully, so that when you are done roasting chicken breast in the air fryer, the rest of the meal is ready. You don't want to leave them in the air fryer while the rest of the meal is finishing. They will continue to cook and become dry if you do. Remove them from the air fryer and place them on a warm platter. Cover the platter with foil to help keep them warm.
