Butter both sides of all the sandwich slices. Add the cheese between the bread and place in the air fryer basket.
Cook in the air fryer at 375 F for 3 to 4 minutes. If preferred, flip over and air fry on the BROIL level for 1 minutes to toast the other side. Repeat to cook all of the sandwiches. If you have a larger air fryer, you might be able to cook more than 2 or more at once.
Enjoy Air Fryer Grilled Cheese as a snack, lunch or dinner.
