You want to know how to cook fully cooked ham in the oven for a beautiful glazed finish. It’s a simple process that makes a fantastic centerpiece for any meal, and getting that perfect sweet and savory crust is easier than you might think.
A fully cooked ham is a convenient choice. It just needs to be warmed through and finished with a glaze. This guide will walk you through every step, from choosing your ham to carving it perfectly.
How To Cook Fully Cooked Ham In The Oven – For Glazed Finish
This method ensures your ham is heated evenly and gets a sticky, caramelized glaze. The key is gentle reheating and applying the glaze at the right time.
What You’ll Need
Gathering your tools and ingredients first makes everything go smoothly.
- A fully cooked, bone-in or boneless ham (size depends on your guests)
- A roasting pan with a rack
- Aluminum foil
- A sharp knife for scoring
- A pastry brush for the glaze
- A reliable meat thermometer
- Ingredients for your chosen glaze (like brown sugar, honey, mustard, or spices)
Choosing the Right Ham
Not all hams are exactly the same. Here’s what to look for at the store.
- Fully Cooked vs. “Heat and Serve”: Most hams sold today are fully cooked. Check the label to be sure. “Heat and Serve” means it’s fully cooked and just needs reheating.
- Bone-In vs. Boneless: A bone-in ham often has more flavor and tends to be juicier. A boneless ham is easier to carve and usually serves more people per pound.
- Spiral-Cut: These are pre-sliced for easy serving. They’re great for convenience, but the glaze can run into the cuts. You’ll need to cover it more carefully to prevent drying out.
Step-by-Step Cooking Instructions
Follow these steps for a perfectly heated and glazed ham every single time.
Step 1: Preheat and Prepare the Oven
Preheat your oven to 325°F (165°C). This lower temperature prevents the ham from drying out while it heats through. Place the oven rack in the lower third of the oven.
Step 2: Prepare the Ham
Remove the ham from its packaging. If it has a plastic cap or netting, take it off. Place the ham, flat side down, on a rack in your roasting pan. If your ham has a lot of fat, you can trim some, leaving about a 1/4-inch layer.
Scoring the fat is the next step. Use a sharp knife to cut a diagonal pattern across the top surface, about 1/4-inch deep. This creates a diamond pattern that helps the glaze adhere and makes the ham look beautiful.
Step 3: Add Moisture and Cover
Pour about 1 to 2 cups of liquid into the bottom of the roasting pan. This creates steam and keeps the ham moist. You can use water, apple juice, pineapple juice, or even cola. Cover the ham tightly with aluminum foil.
Step 4: Calculate the Heating Time
For a fully cooked ham, you just need to heat it to an internal temperature of 140°F (60°C). A general rule is about 10-15 minutes per pound. Always use a meat thermometer to be certain.
Place the foil-covered ham in the preheated oven. Let it heat for most of the calculated time, usually until it reaches about 130°F internally.
Step 5: Prepare Your Glaze
While the ham heats, make your glaze. A simple classic glaze is a combination of:
- 1 cup brown sugar
- 1/4 cup honey or maple syrup
- 2 tablespoons Dijon mustard
- 1 tablespoon apple cider vinegar
Mix these in a saucepan over medium heat until warm and combined. You can also add cloves, pineapple juice, or orange marmalade for different flavors.
Step 6: Apply the Glaze
When the ham’s internal temperature is about 130°F, remove it from the oven. Carefully take off the aluminum foil. Increase the oven temperature to 400°F (205°C).
Use your pastry brush to apply a thick, even layer of glaze all over the scored surface of the ham. Some glaze will drip off, that’s fine.
Step 7: Finish and Caramelize
Return the ham to the hotter oven, uncovered. Bake for another 15-20 minutes, or until the glaze is bubbly and caramelized. You might want to baste it with pan juices once during this time.
Watch it closely to prevent burning. The internal temperature should now reach 140°F. Once it does, take it out of the oven.
Step 8: Rest and Carve
This is a crucial step. Let the ham rest on a cutting board for 15-20 minutes before carving. This allows the juices to redistribute, making every slice moist.
For a bone-in ham, carve perpendicular to the bone. For spiral-cut, just follow the pre-sliced lines. Serve it warm.
Common Glaze Variations
Don’t be afraid to try different glaze flavors. Here are a few popular ideas.
- Brown Sugar & Pineapple: Use pineapple juice in the pan and add crushed pineapple to your glaze mixture.
- Maple & Mustard: Replace the honey with pure maple syrup and use a whole grain mustard.
- Orange & Ginger: Use orange marmalade as the base and add a tablespoon of fresh grated ginger.
- Cola Glaze: Simmer cola with brown sugar until it reduces to a syrupy consistency. It adds a unique depth of flavor.
Troubleshooting Tips
If something doesn’t go as planned, here are some quick fixes.
- Ham is Dry: It was likely overheated. Next time, use a thermometer and don’t exceed 140°F. Adding liquid to the pan and covering tightly is essential.
- Glaze is Burning: Your oven temperature during the glazing phase might be too high. Try 375°F instead of 400°F, or move the ham to a lower rack.
- Glaze Isn’t Sticky: Make sure your glaze has enough sugar and is applied thickly. Letting it cook in the hot oven for the full time is key for caramelization.
- Spiral-Cut Ham Drying Out: Because the slices are exposed, cover it very tightly with foil during the initial heating. You can also tent foil over it during the final glazing if the edges start to look dry.
Storing and Using Leftovers
Ham leftovers are a gift. Store sliced ham in an airtight container in the refrigerator for up to 4 days.
You can use it in so many ways: diced in omelets or scrambled eggs, sliced for sandwiches, chopped in soups or baked pasta dishes, and even on homemade pizza. The bone from a bone-in ham is perfect for making a flavorful soup broth.
Frequently Asked Questions
How long do you heat a fully cooked ham?
Heat it at 325°F for about 10-15 minutes per pound, until the internal temperature reaches 140°F. Always use a meat thermometer for accuracy, as oven temperatures can vary.
What is the best glaze for a pre cooked ham?
A classic brown sugar, honey, and mustard glaze is always a winner. It balances sweet and savory perfectly. But feel free to experiment with maple, fruit juices, or spices like cloves.
Should you cover ham when baking?
Yes, cover it tightly with aluminum foil for most of the heating time. This keeps it moist. Only remove the foil for the last 15-20 minutes when you apply the glaze to let it caramelize.
Can you cook a fully cooked ham without a rack?
You can, but a rack is prefered. It allows heat to circulate evenly. If you don’t have one, create a “rack” with coiled aluminum foil or a layer of sliced onions or carrots in the bottom of the pan to lift the ham slightly.
Do you add water to the pan for ham?
Adding about 1-2 cups of liquid (water, juice, or broth) to the bottom of the pan is a good idea. It creates steam in the oven, which helps prevent the ham from drying out during the long heating time.
How do you keep a spiral ham from drying out in the oven?
Cover it very tightly with foil, making sure the edges are sealed. You can also place the ham cut-side down in the pan to reduce moisture loss. Some people even wrap the whole ham in foil before placing it in the pan.
Final Thoughts
Cooking a fully cooked ham with a glaze is a reliable way to prepare a impressive meal. The process is straightforward: heat it gently, apply a sweet glaze, and let it caramelize. Remember to use a thermometer, don’t skip the resting time, and have fun with the glaze flavors.
With this guide, you can confidently serve a beautiful, flavorful ham that will be the highlight of your table. It’s a classic dish that always feels special, yet is simple enough for any home cook to master.
