Marinate the Chicken: In a mixing bowl, combine buttermilk, garlic powder, salt, pepper, and smoked paprika. Add the chicken and let it marinate for at least 10 minutes (or up to 24 hours for best results).
Prepare the Breading: In a separate shallow dish, whisk together flour, cornstarch, salt, pepper, garlic powder, onion powder, and smoked paprika.
Coat the Chicken: Remove each piece of chicken from the buttermilk mixture, allowing any excess liquid to drip off. Quickly dredge the chicken in the breading mixture, ensuring it’s fully coated on all sides.
Preheat the Air Fryer: Preheat your air fryer to 350°F (180°C) for about 3-5 minutes.
Air Fry the Chicken: Spray the air fryer basket with olive oil spray. Arrange the chicken in a single layer in the basket, making sure there’s enough space for air circulation. Spray the chicken with a light coat of olive oil. Air fry at 350°F for 15 minutes, flip the chicken, and spray with more oil. Continue cooking for another 5 minutes, or until the chicken reaches an internal temperature of 165°F.
Serve: Let the chicken rest for a couple of minutes before serving. Enjoy your crispy, juicy Air Fryer Copycat KFC Fried Chicken!
