Prepare all of the ingredient. Preheat oven to 375deg.
In a small bowl, combine butter, orange zest, lemon zest, rosemary, sage and half of garlic.
Place chicken on rack in baking dish. Stuff orange halves, lemon halves and remaining garlic into cavity.
Gently separate the skin from the flesh, without removing it. Then push a layer of butter under the skin, evenly over the bird. Place any excess butter mixture into the cavity.
Sprinkle salt and pepper evenly over bird. Then loosely cover with aluminum foil. Place in oven for 75 minutes.
Halfway through cook time, remove foil and baste the bird with drippings as needed for the remainder of cook time. Chicken should be cooked to 165 deg internal temperature. Be sure to let chicken sit for at least 5 minutes before carving.
