A 10 lb ham: the smallest whole ham
10 lb starts the USDA chart for whole bone-in hams, which reheat at 15 to 18 minutes a pound: 2 h 30 min to 3 h. That is fewer minutes a pound than a half ham (18 to 24).
A cook-before-eating whole ham of 10 lb takes 3 h to 3 h 20 min and must reach 145°F. For dinner at 6 pm a fully cooked one goes in at 3:00 pm, a cook-before-eating one at 2:40 pm.
Fully cooked hams from a USDA-inspected plant are safe cold, so reheating is optional; leftover or repackaged ham goes to 165°F. Work out your own ham with the ham size calculator, or read how long to cook a ham and how much ham for 20 people.
