Place one slice of bread, butter-side down, in the air fryer basket. Top with 2 slices of cheese, then add another slice of bread with the buttered side facing up. Repeat to make the second sandwich.
Air fry at 370°F for 4 minutes.
Flip the sandwiches and cook at 370°F for 4 more minutes, until the bread is golden brown and the cheese is melted.
Remove the sandwiches from the air fryer, cut them in half, and serve warm.
