Prepare Coating: In another bowl, mix the flour with your chosen spices. A standard mix could include 1 teaspoon each of paprika, garlic powder, onion powder, salt, and ½ teaspoon of black pepper, but feel free to adjust to your taste.

Coat the Chicken: Remove the chicken from the buttermilk, shaking off excess. Dredge each piece in the seasoned flour mixture, coating it thoroughly.

Preheat Air Fryer: Preheat your air fryer to 390°F (200°C). This may take about 3-5 minutes depending on your model.

Arrange Chicken in Air Fryer: Spray the air fryer basket with cooking spray to prevent sticking. Place the coated chicken pieces in the basket in a single layer, leaving some space between each piece for even cooking. Spray the top of the chicken lightly with cooking spray.

Cook: Air fry the chicken for about 10 minutes. Then, flip the pieces over, spray the other side lightly with cooking spray, and cook for another 10-15 minutes, or until the chicken is golden brown and cooked through. The exact time may vary depending on the size of your chicken pieces and the model of your air fryer.

Check for Doneness: The chicken is done when it reaches an internal temperature of 165°F (74°C) when checked with a meat thermometer.

Serve: Let the chicken rest for a few minutes before serving. This helps to lock in the juices, making it more tender and flavorful.
