Preheat oven to 450F
Take the turkey out of the bag, wash it, and pat it dry. Remove the giblet bag from the head cavity and the neck from the body cavity.
Place the turkey in the roasting pan, breast side up. Make sure it is very dry. Add carrots, celery sticks, cut tomatoes, a quartered onion, and baby potatoes in the pan. Add salt and pepper to the bird and vegetables.
Melt a stick of butter and brush the turkey liberally with the melted butter
Pour two cups of chicken broth into the pan, place turkey in the oven, and reduce temperature to 350F. Bake for 13 mins per pound. Every hour, take the turkey out of the oven, baste with broth and brush it with butter. If the turkey is browning faster than it cooks, cover with aluminum foil and keep baking until the internal temperature between the thigh and the breast reaches at least 165F.
