Air Fryer Grilled Cheese is an air-fried sandwich made with lots of cheese between slices of brioche bread.
Preheat an air fryer to 350°F and line the basket with parchment paper.
Spread a tablespoon of mayonnaise on one side of each slice of bread.
Place two slices of bread, mayonnaise side down, into the lined basket of the air fryer.
Top each slice with a cup of shredded cheese and another slice of bread, mayonnaise side up.
Air fry for 5 minutes. Flip the sandwiches over, and cook for an additional 3 minutes. Remove from air fryer and serve immediately.
