Not a good time to preheat the air fryer
#1. Thick raw food
Cook very thick or dense/frozen meats like roasts, large chicken breasts, or anything raw that needs cooking. If you preheat, you’ll cook the outside too quickly and get too crispy before it’s fully cooked in the middle.
This is not good when you are cooking raw, solid, or frozen food. The frozen meat in the middle will remain whole. They will not be cooked. Too hot, or too fast means raw food won’t be fully cooked. They will be the exception if you are grilling rare or medium steaks.
#2. Food doesn’t want to be crispy
Preheating will only make cooked foods hotter and crisper on the outside. In case you grill thinly sliced or chopped vegetables, they may burn on the outside before the inside is tender. So if you preheat, just reduce the cooking time a bit.
#3. Cakes, bread, or similar products
Preheating will make the outside too crispy and the inside will be mushy and raw. The crust will be hard, while the dough inside will be rough. If you make smaller-sized pastries, the inside may cook faster when the air fryer is preheated.
