For a spiral ham, bake it at 325°F and heat it until the internal temperature reaches 140°F. Since it’s usually already fully cooked, you’re really reheating it, not cooking it from raw.

Quick Scoop

  • Oven temp: 325°F.
  • Target internal temp: 140°F.
  • Timing: about 10 to 15 minutes per pound.
  • Tip: cover with foil so it stays moist; remove it a bit early if you want to rest it before serving.

Simple method

  1. Preheat the oven to 325°F.
  1. Place the ham cut-side down in a roasting pan.
  1. Cover tightly with foil.
  1. Heat until the center reaches 140°F.
