Preheat oven to 325°F (165°C). Remove ham from refrigerator and all packaging materials. Place ham face down directly into baking dish or roasting pan. Cover tightly with lid or foil and heat for approximately 20 minutes per lb. or until product center reaches 160°F.
If you intend to glaze your ham, remove ham from the oven ½ hour before end of heating time. Prepare your favorite ham glaze and apply evenly over the surface of the warm ham. Heat glazed ham uncovered for 25 to 30 minutes.
Heating times may vary.
