Combine the salt, pepper, chili powder, garlic powder, onion, powder, cayenne powder, and cumin in a small bowl. Stir the seasonings to thoroughly mix them together.
Rinse the turkey legs under cold water. Then, dry each turkey leg and rub the seasoning mixture over the entire leg.
Lightly spray the turkey legs with cooking oil, making sure to coat the entire leg on all sides. Place the legs in the air fryer basket. Depending on the size of your air fryer, they may need to be cooked in batches.
Place the basket in the air fryer and set it to cook at 380 degrees Fahrenheit for 15 minutes. Turn the legs over halfway though cooking time. *Note: Cooking times can vary from size and style of air fryer. The turkey legs are done when the internal temperature reaches 165 degrees Fahrenheit when checked with a meat thermometer.
Remove from air fryer basket, serve and enjoy!
