Preheat oven to 350°. Spray or lightly grease a 9 x 13 inch pan. A pan with a rack will keep the chicken breading from getting soggy.
Pound chicken breasts to uniform thickness approx. 1/2 to 3/4 inch thick.
In a small flat dish, combine the olive oil or butter with the garlic. In a separate dish, mix the bread crumbs, Parmesan cheese, and basil.
Sprinkle each side of the chicken breast with garlic pepper or salt and pepper. Dip each chicken breast in the oil mixture, then in the bread crumb mixture. Arrange the coated chicken breasts in the prepared baking dish, and top with any remaining bread crumb mixture.
Bake 30-35 minutes in preheated oven. Turn chicken over half way through cooking. Cook until chicken is no longer pink and the juices are clear or until an internal temperature of 165°.
