- Ham to buy
- Per person
- Reheating time
Fully cooked hams only need reheating. Check the label.
Bone-in ham needs more per person because of the bone. Allow about 0.75 lb per person bone-in and 0.5 lb boneless. Twelve guests need a 9 lb bone-in ham, which reheats at 325°F (165°C) in about 2 hours 15 minutes. Add half again for leftovers.
