Rinse the turkey inside and out, and pat dry with paper towels.
Place the turkey in a large roasting pan.
Rub the turkey with melted butter, salt, and pepper.
Stuff the cavity with lemon, onion, garlic, rosemary, and thyme.
Pour chicken broth into the bottom of the roasting pan.
Roast the turkey for about 2 hours, basting occasionally with the pan juices.
