1. Preheat the air fryer: Set your air fryer to 400°F (200°C) and let it preheat for about 5 minutes. This ensures even cooking.

2. Prepare the chicken: Pat the chicken breasts or thighs dry with paper towels. This helps the coating stick better.

3. Coat the chicken: In a mixing bowl, combine the Shake and Bake mix with optional seasonings like paprika, garlic powder, and Parmesan cheese. Place each piece of chicken in the bowl and press the mix onto the chicken until fully coated.

4. Arrange in the air fryer: Lightly spray the air fryer basket with cooking spray. Place the coated chicken pieces in a single layer in the basket. Avoid overcrowding for even cooking.

5. Air fry the chicken: Cook the chicken at 400°F (200°C) for 10 minutes. Flip the chicken halfway through to ensure even crispiness on both sides. Continue cooking for another 8-10 minutes until the chicken is golden brown and crispy.

6. Check for doneness: Use a meat thermometer to ensure the chicken reaches an internal temperature of 165°F (74°C). This guarantees the chicken is cooked through.

7. Crispy chicken tips: For extra crispiness, lightly spray the chicken with cooking spray before air frying.
