This air fryer grilled cheese delivers perfectly golden, crispy results with gooey melted cheese in minutes. It's the ultimate comfort food upgrade you need to try.
In a small bowl, mix the softened butter with the garlic powder and onion powder until well combined.
Spread the garlic butter evenly on one side of each slice of sourdough bread. Place 2 slices butter side down on a cutting board.
Layer 2 slices of sharp cheddar and 1 slice of gruyere on each of the bread slices that are butter side down. Top each with the remaining bread slices, butter side facing up.
Preheat the air fryer to 370°F for 2 minutes.
Place the sandwiches in the air fryer basket. If they do not fit side by side, cook them one at a time. Air fry for 4 minutes until the bottom is golden and crispy.
Carefully flip each sandwich over using a spatula. Air fry for another 3 to 4 minutes until the second side is golden brown and the cheese is completely melted.
Remove from the air fryer, let cool for 1 minute, then slice in half diagonally. Serve immediately while the cheese is hot and stretchy.
