how long to cook a half ham
Ham labeled Cook Before Eating. Preheat the oven to 325Â°F. Place the ham on a rack in a shallow roasting pan. For a whole 10- to 15-pound ham, allow 18 to 20 minutes per pound; for a half--5 to 7 pounds--about 20 minutes per pound; or for a shank or butt portion weighing 3 to 4 pounds, about 35 minutes to the pound. In all cases, cook uncovered until the internal temperature reaches 160Â°F.
