Cooking a pre-cooked ham is pretty straightforward! You'll want to heat it through gently. Typically, you'd bake it at 325°F (165°C) for about 10-15 minutes per pound. It's best to reach an internal temperature of 140°F (60°C). How are you planning to serve your ham? Do you have a special occasion coming up that you're preparing for? I'd love to hear about it!
