Whisk together the sour cream, lime juice, chili powder, garlic powder, salt, and black pepper in a small bowl.
Spray the cooking rack in the air fryer with cooking spray. Spread the chili lime sauce on one tortilla and place it sauce-side up in the air fryer.
Arrange the chicken and cheese on top of the sauce, cover it with the second tortilla, and spray the top with cooking spray.
Secure the quesadilla with 2 or 3 toothpicks by threading them through the edges of the two tortillas.
Air fry for 8 minutes, flipping halfway through.
Remove and let it cool before slicing into fourths and serving with guacamole and pico de gallo.
Notes
Use cooking spray or olive oil: A light brush or spray of oil on the outside of your tortillas will give you that golden, crispy exterior without the greasiness.
Flip it: Halfway through cooking, give your quesadilla a gentle flip. This helps to ensure that both sides get evenly crispy and golden.
Rest: Give your quesadillas a minute or two to cool down before cutting into them. This little break lets the cheese set slightly, making it easier to slice without all the gooey goodness escaping.
Every air fryer is different: If your quesadilla hasn't crisped up after the 8-minute mark, cook it for a few more minutes.
