Take each slice and spread one side with butter (or mayonnaise if you like). This helps it get crispy and golden.
02 -
Start by putting one slice of bread, butter side facing the air fryer basket. Think of this as the sandwich's bottom.
03 -
Lay 2 slices of cheese over the bread in the basket, then top it with a second slice of bread, buttered side up.
04 -
For lightweight or thin bread, stick a toothpick in the middle to stop the top slice from moving around in the air fryer.
05 -
Set your air fryer to 370°F and cook for 4 minutes. No need to preheat most air fryers for this step.
06 -
Carefully flip the sandwich over with a spatula and cook for another 4 minutes at the same temperature. Check for the toasty golden color you like.
07 -
If you're making a second sandwich, repeat the process. Take out toothpicks if used, let the sandwich cool slightly, then slice and enjoy that gooey cheese!
