In a large bowl, mix olive oil, garlic, soy sauce, pepper, rosemary and thyme.
Mix in chicken breasts so they become covered with sauce mixture. Cover and set in refrigerator for 2 hours.
Preheat oven to 425-degrees. Arrange chicken in a 9x13 baking pan, and cover with remaining sauce from bowl. Bake chicken for 20 minutes. Remove from oven and let rest for 2 minutes.
