Lay out the tortillas and top each tortilla with half of the chicken, cheese, red onion, and jalapenos.
Fold in half to close and brush the outside of the tortillas with olive oil.
Gently place in the air fryer basket or on the air fryer trays and top with a metal trivet*.
Cook 4 minutes, open the air fryer and remove the trivet. Flip the quesadillas over and cook an additional 4-6 minutes or until browned and crisp.
Cool 2 minutes before cutting into wedges.
Notes
If you don't have a trivet, secure the tops of the tortillas with toothpicks. Check them after 1 minute as they will sometimes open from the air circulating. Once the cheese has started to melt, they will stay closed.
