For a spiral ham , bake it at 325°F for about 12 to 15 minutes per pound if it’s pre-cooked, which is the most common kind. A good target is to warm it until the center reaches 140°F and then let it rest briefly before slicing.

Quick guide

  • Fully cooked spiral ham: 12 to 15 minutes per pound at 325°F.
  • Internal temperature: remove at about 135°F to 140°F, then rest.
  • Covered with foil: helps keep it moist.

Example

  • 8 lb ham: about 1 hour 40 minutes to 2 hours.
  • 10 lb ham: about 2 hours to 2 hours 30 minutes.
