Slow Cooked Ham Recipe
Cover the bottom of a roasting pan with aluminum foil. Bake ham at 250° for 1 hour. Reduce the heat to 175° and roast another 12-15 hours. This is great because you can put in the oven overnight and it will be ready the next day for the noon meal. The cooking time can go for longer if needed to fit your schedule since it is at such a low temperature.
