For fully cooked ham: preheat oven to 325°F (160°C)
For partially cooked or raw ham: preheat oven to 325°F (160°C)
Remove packaging and any plastic wrap
If ham has a glaze packet, set it aside
Place ham cut-side down in a roasting pan
Add a small amount of water or broth to the bottom of the pan (optional)
Cover loosely with foil for even heating
Calculate time (fully cooked): heat about 10–14 minutes per pound until warmed through
Calculate time (partially cooked): heat about 15–18 minutes per pound until heated through
Calculate time (raw): roast about 20–25 minutes per pound until done
Check temperature with a meat thermometer
Target temperature (fully cooked): 140°F (60°C) in the thickest part
Target temperature (partially cooked): 145°F (63°C) in the thickest part
Target temperature (raw): 160°F (71°C) in the thickest part
For best results, apply glaze during the last 20–30 minutes of cooking
Remove foil during the last 10–15 minutes to help glaze set (optional)
Rest ham 10–20 minutes before slicing
