If needed by your air fryer, preheat the air fryer to 350°F.
Cut each round tortilla into triangles or into shapes using a cookie cutter.
Place a single layer of tortillas in the air fryer basket. Spray with cooking spray and sprinkle with salt.
Cook for 3-4 minutes.
Turn chips over and continue cooking for an additional 3-4 minutes. Each air fryer is different so watch your chips and adjust the cooking time as needed.
Continue cooking in batches until all tortillas are done.
