Preheat the air fryer to 350 degrees F for 3 minutes.
Spray the basket or racks with oil, place the frozen ravioli in a single layer, and spray them with oil. Cook for 3-4 minutes, then flip and continue cooking another 3 minutes.
Notes
Spray oil is optional -- It helps get a great crispy browned exterior, but the ravioli is good without it as well.
