Reheating nuggets from Chick-fil-A does not take a long time at all.Prepare the food in the air fryer by setting it to AIR FRY at 420 degrees for four minutes.The high temperature and short cooking time combine to produce an exterior that is crisp and hot on the inside.There is NO need to preheat; the given cooking time accounts for both the stage where the oven is heated up and the countdown to the end of the cooking period of 4 minutes.
