Step 1

First, combine the room temperature butter, grated Parmesan, and Italian seasoning in a bowl. Then, spread the butter mixture over one side of each piece of bread, from edge to edge.

Step 2

Place the sliced cheese between the two pieces of bread, buttered sides facing out.

Step 3

Preheat the air fryer (if yours does not have a preheat setting, let it run for about four minutes at 400ºF).

Step 4

Finally, place the sandwich in the air fryer basket. Cook at 350ºF for five minutes, then flip and cook for 5 minutes on the other side, or until golden brown and crispy and the cheese is melted through. Slice and serve.
