Soak the chicken strips in the buttermilk along with the salt and freshly ground pepper for 30 minutes to 1 hour.
In a shallow container, whisk together the panko, garlic powder, white pepper, onion powder, and salt.
Take a strip of chicken out of the buttermilk, shake gently, then coat in panko, pressing to ensure all sides are covered. Place in the fry basket of the air fryer, being careful not to crowd. Continue to coat all of the chicken.
Lightly spray the chicken with cooking oil. Cook at 400°F for 5 minutes, then flip and continue to cook for another five minutes, or until cooked through and crispy, up to 10 minutes more. Enjoy hot!
