Most hams at the grocery store are already cooked, or smoked, so you just have to heat them up. One of my favorite ways to heat a ham is to roast it in the oven.
This flavorful ham is perfect for special occasions, particularly a holiday meal. I often make it for Christmas dinner or Easter Sunday dinner and serve it with Cheesy Air Fryer Scalloped Potatoes and Slow Cooker Red Cabbage.
If you have a smoker, another great way to heat a ham is by using this Double Smoked Ham Recipe.

For more detailed instructions with measurements, jump to the recipe card.
- Ham. I used a bone-in pre-cooked ham that was about 9.5 pounds. This recipe will work with any kind of ham, including whole ham, boneless ham, country ham, spiral-sliced ham, half ham, or fresh ham.
- Pineapple chunks. You can also use crushed pineapple, pineapple slices, or fresh pineapple.
- Dijon mustard. You can also use yellow mustard.
How To Heat A Fully Cooked Ham
- Step 1. Remove the ham from the refrigerator about an hour before baking so it can come up to room temperature.
- Step 2: Preheat the oven to 325 degrees F.
- Step 3: Remove the packaging from the ham, along with the plastic circle that covers the bone.
- Step 4: If your ham is not spiral-cut, score the entire surface of the ham with a sharp knife, which helps the glaze sink into the meat. Cut long cuts from the top of the ham down to the bottom. Then, make a second set of perpendicular cuts to form a diamond pattern all over the outside, about ½-inch deep and 1-½-inches apart.
- Step 5: Place the ham cut side down in a large roasting pan or sturdy baking dish. Add 1 cup of cold water to the bottom of the pan. Cover with a lid or with aluminum foil to prevent the ham from drying out.
- Step 6: Put the ham in the oven and bake for one hour at 325 degrees F.
Prepare The Pineapple Glaze
- Step 7. Add the entire can of pineapple tidbits, including the juice, to a medium saucepan, along with brown sugar, orange juice, Dijon mustard, cinnamon, and ground cloves. Stir well to combine. Bring to a boil, then reduce to low heat and simmer for 30 minutes, until the glaze has thickened.
- Step 8. After the ham has been in the oven for one hour, remove the lid and pour a few spoonfuls of glaze over the top of the ham. Add all of the pineapple chunks to the roaster beside the ham. Reserve the remaining glaze for later.
- Step 9. Cover again and bake for another hour. Pour the remaining glaze over the ham and cover it again. Bake in the oven for one more hour, or until the internal temperature in the thickest part of the ham reaches 140 degrees F with a meat thermometer.
- Step 10. Remove the ham from the oven and let it rest, tented in foil, for 15 minutes. Slice and serve with your favorite side dishes. Enjoy!
Top Tip
Most hams sold in the grocery store are city hams (pre-cooked). However, if you are cooking a fresh ham, it is always sold uncooked, and it needs to be cooked until the internal temperature reaches 145 degrees F.
Serving Suggestions
Serve this baked ham with Green Bean Casserole, Twice-Baked Mashed Potatoes, and Ruth’s Chris Sweet Potato Casserole.

Top Tips
- Ensure you cover the ham with a lid or aluminum foil for most of the baking time; this will keep moisture locked in and give you juicier meat.
- Use an internal thermometer for accuracy. You want to make sure that your ham reaches an internal temperature of 140 degrees Fahrenheit.

How To Heat A Fully Cooked Ham FAQs
A pre-cooked ham needs to be heated to an internal temperature of 140 degrees F. A fresh ham (uncooked) needs to be heated to an internal temperature of 145 degrees F.
For a pre-cooked ham, you need to heat it to an internal temperature of 140 degrees F. This will take approximately 18 to 20 minutes per pound. My ham was almost 10 pounds, and it took 3 hours to heat. The size of the ham will determine the length of the cooking time; a smaller ham will cook much quicker than a larger one.
If you figure about ½ pound per person with a bone-in ham and ⅓ pound per person if it is a boneless ham, you will have enough to feed everyone and have some leftovers if you are lucky.
Leftover ham should be stored in an airtight container or wrapped tightly in plastic wrap. It can be stored in the refrigerator for 3-4 days, or in the freezer for up to two months.
Yes! To heat your ham in the slow cooker, place ham in the slow cooker with 1 cup of water, and heat on low for 4-5 hours. Then remove the lid and pour the glaze over top of the ham. Cover and cook on low for 30-60 minutes, until the internal temperature reaches 140 degrees F.
What to do with leftover ham?
Use leftover ham in a Western Oven-Baked Omelet Casserole, Instant Pot Ham and Potato Soup, Instant Pot Scalloped Potatoes and Ham, or Split Pea Soup With Leftover Ham.
I also like making homemade breakfast sandwiches with a ham slice and fried eggs on my Fluffy Air Buns or No Knead Sourdough Bread.
