Bake a ham at 325 degrees F for the most common oven method. For a fully cooked ham , heat until the internal temperature reaches 140 degrees F ; for a ham that must be cooked before eating, cook to 145 degrees F and let it rest 3 minutes.

Quick Scoop

  • Oven temp: 325 degrees F.
  • Fully cooked ham: reheat to 140 degrees F.
  • Cook-before-eating ham: heat to 145 degrees F , then rest 3 minutes.
  • Use a meat thermometer in the thickest part, avoiding bone.

Handy tip

If you’re glazing the ham, add the glaze near the end so it doesn’t burn, and start checking temperature a bit early because ovens vary.
