Easy Roasted Chicken Preheat oven to 375°. Cut a whole fryer chicken down bottom side, so it will lay flat in pan, and place in roasting pan. Season with salt & pepper. Pour 1 - 1 1/2 cups of dry vermouth (don't use sweet... dry has 2 carbs per 8 oz... sweet has about 30-some) over top. Peel one head of garlic (approx. 15 cloves), and pile on top of chicken. Slice 3 stalks of celery, and one small yellow onion into chunks, pile on top of garlic and chicken. Cover roasting pan, bake for 1 1/2 - 2 hours. Chicken will be tender and flavorful!
