Cooking a fully cooked ham is simpler than most people think. You just need the right ham recipe, oven temperature, and a little patience. This guide shows you how to reheat and glaze fully cooked ham so it stays moist and flavorful.
Cooking a fully cooked ham might sound intimidating, but it really isn’t. Whether you’re preparing a holiday dinner or a weeknight meal, reheating a pre-cooked ham the right way makes all the difference. A good ham recipe takes the guesswork out of the process and gives you a beautiful, juicy centerpiece every time.
The key to a great fully cooked ham is gentle reheating. You don’t want to cook it further — you just want to warm it through. This means low and slow is your best friend. In this guide, we walk you through every step, from choosing your ham to pulling it out of the oven perfectly done.
Key Takeaways
- Oven Method is Best: Reheat your fully cooked ham at 325°F for even heating and a beautiful finish.
- Glaze Early: Apply your ham glaze in the last 15-20 minutes to prevent burning.
- Use a Meat Thermometer: Always check that your ham internal temperature reaches 140°F for food safety.
- Don’t Overcook: Fully cooked ham only needs reheating, not cooking from raw. Overcooking dries it out fast.
- Rest Before Slicing: Let the ham rest 10-15 minutes after cooking for juicier slices.
- Store Properly: Keep leftover reheated ham in the fridge for up to 5 days.

What Is a Fully Cooked Ham?
A fully cooked ham has already been cured, smoked, or baked before it reaches your kitchen. You’ll often see labels that say “cooked,” “ready to eat,” or “fully cooked.” These hams are safe to eat cold right out of the package. But most people prefer to warm them up and add a sweet ham glaze for a festive touch.
Types of Fully Cooked Ham
Not all hams are the same. Here are the most common types you’ll find at the store:
- Spiral Ham: Pre-sliced and easy to serve. A spiral ham is one of the most popular choices for holidays.
- Whole Ham: A full bone-in or boneless ham. Great for large gatherings.
- Half Ham: A smaller portion perfect for intimate dinners.
- Ham Steak: Thick slices that cook fast. Perfect for a quick ham dinner.
- Brown Sugar Ham: A style coated with a sweet brown sugar mixture before cooking.
Each type works well for reheating. The method stays mostly the same, but timing varies based on size and whether the ham is bone-in or boneless.
How to Cook Fully Cooked Ham in the Oven
The oven is the most popular way to reheat a fully cooked ham. It gives you even heat and a lovely caramelized top when you add a glaze. Follow these steps for the best results.
Step-by-Step Oven Method
- Preheat your oven to 325°F. This low temperature warms the ham gently without drying it out.
- Remove the ham from its packaging and place it cut-side down in a baking dish or roasting pan.
- Cover the ham tightly with aluminum foil. This traps moisture and keeps the meat juicy.
- Heat for 10-15 minutes per pound. A 10-pound ham will take roughly 1.5 to 2.5 hours.
- Remove the foil during the last 20 minutes to let the exterior caramelize.
- Check the internal temperature. Your ham internal temperature should reach 140°F when measured at the thickest point.
- Let the ham rest for 10-15 minutes before slicing.
This method works beautifully for both bone-in and boneless hams. The bone actually helps keep the meat moist during reheating. If you’re using a ceramic baking dish, that’s perfectly fine too — just make sure it’s oven-safe.

Oven Temperature and Timing Chart
Here’s a quick reference for cooking ham in oven times:
- 5-7 lbs: 1 to 1.5 hours covered, then 15-20 minutes uncovered
- 8-10 lbs: 1.5 to 2 hours covered, then 20 minutes uncovered
- 10-15 lbs: 2 to 3 hours covered, then 20-30 minutes uncovered
- 15+ lbs: 3+ hours covered, then 30 minutes uncovered
Always use a meat thermometer. Visual cues can be misleading, and you want to make sure your reheated ham reaches a safe temperature throughout.
Stovetop and Slow Cooker Methods
Not everyone has an oven, or maybe you want to try a different approach. Good news — you can reheat a fully cooked ham on the stovetop or in a slow cooker too.
Stovetop Method
The stovetop method works best for ham steaks and smaller portions. Place the ham in a deep skillet or pot with a lid. Add a splash of broth, apple juice, or water to keep it moist. Cover and heat on low for about 10-15 minutes per pound. Turn the ham occasionally for even warming.
This method is fast and efficient. It’s perfect for weeknight meals when you need a ham dinner on the table quickly. Just be careful not to let the liquid boil — you want a gentle simmer.
Slow Cooker Method
If you prefer set-it-and-forget-it cooking, a slow cooker works well for a whole fully cooked ham. Place the ham in the cooker, add about one cup of liquid (broth, juice, or water), and cook on low for 4-6 hours or on high for 2-3 hours.
If you don’t own a slow cooker, you can achieve similar results using your oven. Learn how to slow cook without a slow cooker using your Dutch oven or oven for the same tender results.
The slow cooker method keeps the ham incredibly moist. It’s a hands-off approach that frees up your oven for side dishes like casseroles or roasted vegetables.
Making the Perfect Ham Glaze
A great ham glaze turns a simple reheated ham into a showstopper. The glaze adds sweetness, shine, and flavor that everyone loves. Here are some classic options.
Classic Brown Sugar Glaze
This is the most popular glaze for a reason. It’s simple, sweet, and caramelizes beautifully.
- 1 cup brown sugar
- 1/4 cup honey
- 2 tablespoons Dijon mustard
- 1 tablespoon apple cider vinegar
- 1 teaspoon cloves (optional)
Mix all ingredients in a bowl until smooth. Brush the glaze over the ham during the last 20-30 minutes of cooking. The heat will melt the sugar and create a sticky, delicious crust.
Pineapple and Cherry Glaze
This tropical-style glaze pairs well with spiral ham. Use crushed pineapple, cherry preserves, and a splash of bourbon for a sweet and tangy finish.
Honey Mustard Glaze
For a tangier option, mix equal parts honey and Dijon mustard. Add a pinch of black pepper and a dash of apple cider vinegar. This glaze works great on brown sugar ham too.
When to Apply the Glaze
The most important rule about glazing is timing. Apply your ham glaze during the last 15-20 minutes of cooking. If you put it on too early, the sugar will burn and turn bitter. You want a golden, caramelized coating — not a blackened mess.
For even coating, apply the glaze in thin layers. Two to three coats give you the best results. Baste the ham with the glaze each time you apply it.
Serving and Storing Cooked Ham
Once your fully cooked ham is done, it’s time to serve it up. Let it rest for 10-15 minutes before slicing. This resting period allows the juices to redistribute, making every slice tender and moist.
How to Slice a Ham
For a spiral ham, the slices are already done for you — just pull them apart gently. For a whole ham, cut along the bone to create even slices about 1/4 inch thick. A sharp knife makes this much easier. If you need help with knife skills, our guide on how to sharpen Japanese knives can help you get a clean edge.
Storing Leftover Ham
Leftover reheated ham keeps well in the refrigerator. Wrap it tightly in plastic wrap or foil and store it for up to 5 days. You can also freeze ham for up to 3 months. Just make sure to wrap it in freezer-safe packaging to prevent freezer burn.
Here are some quick serving ideas for leftover ham:
- Ham and cheese sandwiches
- Ham and egg breakfast skillets
- Ham soups and stews
- Ham fried rice
- Ham and pineapple pizza
Don’t toss those leftovers! Fully cooked ham reheats beautifully and adds protein and flavor to all kinds of dishes throughout the week.
Common Mistakes to Avoid
Even experienced cooks make mistakes when reheating ham. Here are the most common ones and how to avoid them.
- Cooking at too high a temperature. High heat dries out ham fast. Stick to 325°F for even, gentle reheating.
- Leaving the foil on the entire time. The ham needs uncovered time at the end to develop a nice glaze and color.
- Over-glazing too early. Sugar burns quickly. Always apply glaze in the final 15-20 minutes.
- Skipping the thermometer. Guessing the temperature leads to undercooked or overcooked ham. A quick read with a meat thermometer saves the day.
- Forgetting to rest the ham. Cutting into hot ham immediately releases all the juices. Patience pays off with juicier slices.
- Not adding liquid. Ham without any moisture in the pan dries out. Add broth, juice, or water to the bottom of your pan.
Expert Tips for Perfect Ham Every Time
Here are some pro tips that make a real difference in your fully cooked ham results:
Score the ham before glazing. Use a sharp knife to make shallow diamond cuts across the surface. This gives the glaze more surface area to cling to and creates a beautiful presentation.
Add whole cloves to the ham. Stud the exterior with whole cloves for a classic flavor boost. The cloves infuse the ham with warm, aromatic notes during cooking.
Use the pan drippings. After cooking, save the liquid in the bottom of the pan. Mix it with a little cornstarch to create a simple pan sauce that pairs wonderfully with the ham.
Let the ham come to room temperature before cooking. Take it out of the fridge 30 minutes before reheating. This helps the ham warm more evenly and reduces cooking time slightly.
For a crispy exterior, remove the foil and brush on a second layer of glaze during the last 10 minutes. Crank the oven up to 400°F for just those final minutes to get a beautiful caramelized crust.

Why Cook Fully Cooked Ham at Home?
You might wonder why bother reheating a ham that’s already cooked. The answer is simple — flavor and presentation. A fully cooked ham straight from the package is fine to eat, but warming it up and adding a homemade glaze transforms it into something special.
When you cook fully cooked ham at home, you control the ingredients. You decide how sweet or savory the glaze is. You choose whether to add cloves, pineapple, or bourbon. This level of customization is impossible with a store-bought, pre-glazed ham.
Plus, the aroma of a ham baking in the oven fills the entire house. It creates a warm, welcoming atmosphere that makes any meal feel like a celebration. Whether it’s Thanksgiving, Easter, a Sunday dinner, or just a Tuesday night treat, a perfectly reheated ham always impresses.
The process is forgiving too. Ham is a resilient cut of meat. Even if you slightly overcook it, it still tastes better than most deli options. That makes it a great choice for beginner cooks who want to impress without stress.
