Typically this is about 18 minutes per pound but Iâll sometimes pull mine out about 20 minutes before that since it will stay warm in the tinfoil (and even room temperature ham is MUCH better than dry)!

Ingredients for Baked Ham with Brown Sugar Glaze; Tin Foil; Roasting pan; How to: 1. Heat oven to 325Â°F. 2. Place ham, fat side up, on a rack in a shallow roasting pan. 3. Cover loosely with foil and roast ham as directed until the thermometer reads 135Â°F. 4. About 20 minutes before ham is done, remove from oven. Cut uniform diamond shapes on fat surface of ham.
