No, you don't need to bread your chicken breasts first. The secret is to use my marinade. This helps keep the breasts juicy and flavorful and helps to prevent them from drying out. This method makes it perfect for anyone that is trying to follow a low carb diet. My marinade is so simple to make. Make sure that the breasts are covered by the marinade completely. You can flip them partway through if you need to. The oil will help them turn out crispy with no breading required.
