Making Crispy Chicken Tenders in the Air Fryer is straightforward. Just follow these simple steps:

1. Marinate the Chicken: In a bowl, add the chicken tenderloins and pour the buttermilk over them. Cover and let them marinate in the refrigerator for at least 30 minutes for maximum tenderness.

2. Prepare the Coating: In another bowl, mix together the flour, garlic powder, onion powder, paprika, salt, black pepper, and cayenne pepper (if using).

3. Coat the Chicken: Remove the marinated chicken from the fridge. One piece at a time, dredge the tenderloins in the flour mixture until they are completely coated. Shake off excess flour.

4. Preheat the Air Fryer: Set your air fryer to 400°F (200°C) and allow it to preheat for about 5 minutes.

5. Arrange the Tenders: Lightly spray the air fryer basket with cooking spray, then place the coated chicken tenders in the basket in a single layer, ensuring they don’t overlap.

6. Spray with Oil: Lightly spray the tops of the chicken tenders with cooking spray to promote browning and crispness.

7. Cook: Air fry the tenders for 10-15 minutes, flipping them halfway through, until they are golden brown and cooked through. The internal temperature should reach 165°F (75°C).

8. Check for Doneness: Use a meat thermometer to ensure each tender is cooked to perfection. Adjust cooking time as needed based on the thickness of your chicken.

9. Serve Immediately: Once cooked, remove the chicken tenders from the air fryer. Allow them to cool slightly before serving.
