Cooking a pre-cooked ham is quite simple and can make a delicious meal! You usually just need to heat it up. Often, setting your oven to 325°F and warming the ham for about 10 minutes per pound is a good start. Adding a glaze like honey or brown sugar can enhance the flavor. Do you have a special occasion for this ham, or are you trying a new recipe? I'd love to hear more about your cooking plans!
