Using a food processor to make a zesty lemon pepper seasoning takes this air fryer chicken breast recipe to another level. Combine lemon zest, black pepper, garlic powder, onion powder, salt, and paprika in the food processor. Process until you have a fine seasoning. Rub the seasoning all over the chicken breast and let it marinate for at least 30 minutes. Then, place the chicken breast in the air fryer and cook until it's tender and golden. The result is a tangy and peppery chicken breast with a crispy exterior.
