Step 1

On the air fryer, select the air fry mode, set to 360 degrees and preheat until the appliance signals it’s ready.

Step 2

On one side of each slice of bread, apply a thin layer of your preferred sandwich spread, if using. Pile the cheese and filling, if using, on one of the slices of bread and cover with the other slice, spread side down. Apply a thin layer of the mayo, oil or butter on the outside of the top and bottom of the sandwich.

Step 3

Transfer the sandwich to the air fryer basket and air fry for 8 minutes, or until both sides of the sandwich are crisp and golden, flipping halfway through.

Step 4

Let the sandwich rest for 1 to 2 minutes – the cheese will be very hot and melty – before slicing and serving.
