A 9 lb spiral ham
9 lb is the top of the USDA spiral-cut chart: 1 h 30 min to 2 h 42 min at 325°F. A spiral ham is fully cooked, so the aim is 140°F, or 165°F if it was repackaged outside the plant, not a long bake.
Add any glaze only for the last part of the time, since sugar burns. At the high USDA serving a 9 lb bone-in ham feeds 18 people, and 27 at the low serving when it shares the table with other dishes.
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.
