Ham for 10 people by serving size
The USDA allows 1/3 to 1/2 lb of bone-in ham a person, or 1/4 to 1/3 lb of boneless, because the bone is weight you buy but do not eat. Pounds are rounded up.
| Serving | Bone-in ham | Boneless ham |
|---|---|---|
| Low end: with several other dishes | 4 lb (1/3 lb each) | 3 lb (1/4 lb each) |
| High end: ham is the main dish | 5 lb (1/2 lb each) | 4 lb (1/3 lb each) |
| Generous: with leftovers | 8 lb | 5 lb |
Adding children
Children count as half a portion at the high USDA serving.
| Guests | Bone-in | Boneless |
|---|---|---|
| 10 adults | 5 lb | 4 lb |
| 10 adults and 2 children | 6 lb | 4 lb |
| 10 adults and 4 children | 6 lb | 4 lb |
| 10 adults and 6 children | 7 lb | 5 lb |
Reheating a ham for 10
Fully cooked hams at 325°F to 140°F. The USDA timetable lists each kind for a range of weights; for 10 guests the plan is a 5 lb half bone-in ham.
| Kind of ham | For 10 | USDA chart weights | Time at 325°F |
|---|---|---|---|
| Cooked, whole, bone-in | 5 lb | 10 to 14 lb (outside: check the label) | 1 h 15 min to 1 h 30 min |
| Cooked, half, bone-in | 5 lb | 5 to 7 lb | 1 h 30 min to 2 h |
| Cooked, spiral-cut (whole or half) | 5 lb | 7 to 9 lb (outside: check the label) | 50 min to 1 h 30 min |
| Cooked, boneless (vacuum packed) | 4 lb | 6 to 12 lb (outside: check the label) | 40 min to 1 h |
Ten guests: a half ham is the right size
The high USDA serving gives 5 lb of bone-in ham for ten, which is a half ham: the chart covers 5 to 7 lb. It reheats in 1 h 30 min to 2 h at 325°F, so for dinner at 6 pm it goes in at 4:00 pm.
If four children join, counted as half a portion each, the ham goes up to 6 lb. Glaze only for the last part of the bake, since sugar burns over a long time in the oven.
