Using a food processor to make a Mediterranean marinade adds a burst of flavor to air fryer chicken breast. Combine olive oil, lemon juice, garlic, oregano, thyme, rosemary, salt, and pepper in the food processor. Process until you have a smooth marinade. Coat the chicken breast with the marinade and let it marinate for at least 1 hour. Then, place the chicken breast in the air fryer and cook until it's tender and golden. The result is a juicy and flavorful chicken breast with a Mediterranean twist.
