In a small mixing bowl, combine the softened unsalted butter, minced garlic, chopped parsley, salt, black pepper, and red pepper flakes (if you desire a bit of spice). Mix thoroughly until all the ingredients are well incorporated into a smooth garlic butter spread.
On a clean and even surface, lay out each tortilla flat. Using a spatula or the back of a spoon, spread a generous layer of the garlic butter mixture over one side of each tortilla, ensuring even coverage from edge to edge.
Evenly sprinkle the shredded mozzarella cheese and cheddar cheese over the buttered sides of the tortillas, distributing the cheese generously for that perfect melty experience.
Carefully fold each tortilla in half, with the cheese side facing inwards, forming a half-moon shape that encapsulates the cheesy goodness.
Preheat your air fryer to a temperature of 350°F (175°C) for approximately 3 minutes to ensure even cooking.
Once preheated, arrange the folded tortillas in the air fryer basket in a single layer. If your air fryer has limited space, you may need to cook in batches to avoid overcrowding.
Air fry the tortillas for 6-8 minutes. Be sure to flip each one halfway through the cooking time to achieve that glorious golden-brown crust. The cheese should be melted and bubbly, creating an irresistible aroma.
After air frying, carefully remove the cheesy garlic bread from the air fryer and allow them to cool for about a minute. Then slice each half-moon into wedges for easy serving.
Notes
Serve warm with marinara sauce or sour cream for dipping.
