Ham Cooking Times Reference Chart (USDA)
All oven times at 325°F. Always verify internal temperature — time is an estimate. Pre-cooked hams are already safe to eat cold; you are just reheating them.
| Ham Type & Weight | Oven (325°F) Time | Air Fryer (325°F) | Target Temp | Glaze Timing |
|---|---|---|---|---|
| Pre-cooked bone-in (5–7 lbs) | 1.5–2 hours | 75–90 min (max 8 lbs) | 140°F | Last 30 min |
| Pre-cooked bone-in (7–10 lbs) | 2–2.5 hours | Oven recommended | 140°F | Last 30 min |
| Pre-cooked bone-in (10–15 lbs) | 2.5–3.5 hours | Oven only | 140°F | Last 45 min |
| Spiral-cut ham (5–8 lbs) | 1–1.5 hours | 60–80 min (covered) | 140°F | Last 20 min |
| Fresh (raw) ham (5–8 lbs) | 2.5–3 hours | Not recommended | 145°F | Last 30 min |
| Fresh (raw) ham (8–12 lbs) | 3–4 hours | Oven only | 145°F | Last 45 min |
Frequently Asked Questions
How long to cook a ham per pound?+
Pre-cooked ham: 15–18 min/lb at 325°F to reheat to 140°F. Spiral-cut: 10–15 min/lb. Fresh (raw) ham: 25–30 min/lb to reach 145°F. Always use a thermometer — these are estimates.
What temperature should ham be cooked to?+
Fresh (raw) ham: 145°F + 3 min rest. Pre-cooked ham (reheating): 140°F. Spiral-cut pre-cooked: 140°F. Pre-cooked ham can be served cold directly from the package — reheating is optional but adds flavor from glazing.
When should I apply glaze to ham?+
Apply glaze in the last 30–45 minutes of cooking, in 2–3 layers every 10–15 minutes. Glazing too early burns the sugars before the ham is ready. For spiral-cut ham, separate the slices slightly before glazing so it gets between the layers.
How long to cook a 10-pound ham?+
A 10-lb pre-cooked ham at 325°F takes about 2.5–3 hours to reach 140°F. A 10-lb fresh ham takes about 4–4.5 hours to reach 145°F. Cover with foil for the first two-thirds of cooking to retain moisture, then uncover and glaze.
Should I cover ham with foil while cooking?+
Yes — cover the ham with foil for the first two-thirds of the cooking time to retain moisture and prevent the outside from drying out. Remove the foil for the final 30–45 minutes to allow glazing and browning.
Cook times are based on USDA Food Safety guidelines. Ham type matters significantly: a pre-cooked ham is already safe to eat cold — you are only reheating it. A fresh (raw) ham requires full cooking to 145°F, like a pork roast. Always use a meat thermometer. Times listed assume ham starts at refrigerator temperature (fully thawed).
