Begin by setting your air fryer to 360°F (180°C) as per the manufacturer's instructions. In a mixing bowl, combine the chicken with chili powder, cumin, and cayenne pepper for a flavorful kick.
Lay a tortilla flat on a clean surface and sprinkle approximately 2 tablespoons of shredded cheese on one half of it. Add 2 tablespoons of the seasoned chicken mixture on top, followed by another 2 tablespoons of cheese.
Fold the tortilla over to create a half-moon shape and secure the edges with toothpicks. Lightly mist both sides of the quesadilla with olive oil spray to ensure a golden finish.
Carefully place the quesadillas in the air fryer basket in a single layer and cook until the tortillas are crispy and the cheese is melted, about 4 minutes per side. You may need to prepare them in batches. Serve them warm alongside your favorite dips or toppings.
For optimal melting, choose cheeses like Monterey Jack, Cheddar, or Pepper Jack. Consider using queso asadero for added creaminess. For the best results, buy cheese in bulk and grate it yourself, as pre-grated cheese often contains anti-caking agents that hinder smooth melting.
