Creating Crispy Buttermilk Air Fryer Chicken is easy when you follow these simple steps:

1. Marinate Chicken: In a large bowl, combine the buttermilk, garlic powder, onion powder, smoked paprika, cayenne pepper, salt, and black pepper. Add the chicken thighs, ensuring they are fully submerged. Cover and refrigerate for at least 30 minutes, or up to overnight for maximum flavor.

2. Prepare Coating: In another bowl, place the flour. You can add additional spices to the flour for extra flavor if desired.

3. Preheat Air Fryer: Preheat your air fryer to 380°F (193°C) for about 5 minutes.

4. Coat Chicken: Remove the chicken from the buttermilk marinade, allowing excess to drip off. Dredge each piece in the flour, ensuring an even coating. Shake off any excess flour.

5. Spray Chicken: Lightly spray the coated chicken with cooking spray or olive oil to help achieve a golden color.

6. Arrange in Air Fryer: Place the chicken thighs in the air fryer basket in a single layer, making sure they are not overcrowded. You may need to cook in batches.

7. Cook: Air fry the chicken at 380°F (193°C) for 25-30 minutes, flipping halfway through. The chicken is done when the internal temperature reaches 165°F (74°C) and the coating is crispy and golden brown.

8. Rest: Once cooked, remove the chicken from the air fryer and let it rest for about 10 minutes to allow the juices to redistribute.

9. Serve: Enjoy your crispy buttermilk chicken as is or with your favorite dipping sauces.
