Place the chicken in a large bowl and cover with buttermilk. Make sure all the pieces are submerged in the buttermilk. Allow the chicken to marinate for at least 30 minutes, but the longer the better. (You can make your own buttermilk by combining 1.5 cup milk of choice with 2 tbsp Lemon Juice or Vinegar. Let it sit for 10 minutes to curdle, then use.)
In a small bowl (or large Ziploc bag), mix together the flour, cornstarch, and seasonings.
Using tongs, coat each chicken wing in the flour mixture and transfer to a plate or wire rack.
Preheat the air fryer to 380°F (165°C) for 5 minutes.
Lightly spray the air fryer basket with oil. Place the chicken in a single layer into the air fryer basket. Do not overcrowd the air fryer basket or place chicken on top of each other.
Cook at 380°F for 10 minutes. Open the basket and spray any parts of the chicken showing flour with cooking oil spray. Flip the chicken and cook for another 10-12 minutes, until no longer pink and an instant thermometer reads 165°F.
Serve and Enjoy! OR top with Chimichurri sauce
