Season the turkey steaks with salt and pepper. Place them into the air fryer basket without overlapping as much as possible.
Spray the turkey steaks with cooking oil (or brush with olive oil).
Cook on 390° F for for 8-11 minutes, flipping over halfway through. Cook time will vary depending on the thickness of the turkey. The internal temperature should reach 165° at its thickest point.
All air fryers have different wattage and may cook at different rates. You may need to adjust the time or temp for the best results.
