You can use an air fryer for frozen pies. The frozen products in the air fryer do not need to be thawed, so the frozen pies can be cooked directly in the air fryer. The air fryer uses air to replace the hot oil in the original frying pan, and uses convection heating similar to the sun's hot air to form a rapidly circulating heat flow in the closed pot, so that the food is cooked. At the same time, the hot air also blew away the moisture on the surface of the food, so that the ingredients can achieve the effect of approximate frying without rolling oil.
