Slow-cooking a bone-in spiral ham in a low oven allows the natural sugars to caramelize without drying out the meat. If you’ve been wondering how to cook a bone in spiral ham properly, you are in the right place. This guide will walk you through every step, from thawing to glazing, so you get a juicy, flavorful ham every time.
A bone-in spiral ham is already fully cooked, so your job is mainly to reheat it gently and add flavor. The key is to avoid high heat, which can make the meat tough and dry. Instead, we will use a low temperature and a simple glaze to lock in moisture and create a beautiful finish.
Let’s get started with the basics. You will need a roasting pan, a meat thermometer, and some aluminum foil. The ham itself should be at room temperature before it goes into the oven, so take it out of the fridge about 30 minutes ahead.
Preparing Your Bone In Spiral Ham
Before you even turn on the oven, there are a few steps to follow. First, remove the ham from its packaging. Discard any plastic coverings or absorbent pads. Rinse the ham briefly under cold water to remove any excess salt or brine, then pat it dry with paper towels.
Place the ham cut-side down in your roasting pan. This position helps keep the meat moist as the fat cap renders and bastes the slices. If your ham came with a glaze packet, you can set it aside or discard it—homemade glaze is usually better.
Cover the ham tightly with aluminum foil. This traps steam and prevents the outer layers from drying out during the initial heating phase. You will remove the foil later to apply the glaze and caramelize the surface.
Thawing A Frozen Spiral Ham
If your ham is frozen, plan ahead. Thaw it in the refrigerator for 24 hours per 5 pounds of meat. Never thaw a ham on the counter, as this can promote bacterial growth. A fully thawed ham will reheat evenly and safely.
For a 10-pound ham, that means about two days in the fridge. If you are short on time, you can submerge the sealed ham in cold water, changing the water every 30 minutes. This method takes about 30 minutes per pound.
How To Cook A Bone In Spiral Ham
Now we get to the main event. Set your oven to 325°F (163°C). While the oven preheats, place the foil-covered ham in the roasting pan. Insert a meat thermometer into the thickest part of the ham, avoiding the bone.
Cook the ham for about 10 to 14 minutes per pound. For a 10-pound ham, that is roughly 1 hour and 40 minutes to 2 hours and 20 minutes. The internal temperature should reach 140°F (60°C) when done.
About 20 minutes before the ham is finished, remove it from the oven. Increase the oven temperature to 400°F (204°C). Carefully take off the foil and brush your glaze all over the surface of the ham. Make sure to get the glaze between the slices.
Return the ham to the oven, uncovered, for 15 to 20 minutes. The glaze will bubble and caramelize, creating a sticky, golden crust. Keep an eye on it to prevent burning.
Making A Simple Glaze
A good glaze balances sweet and savory. Here is a basic recipe that works with most spiral hams:
- 1/2 cup brown sugar, packed
- 1/4 cup honey or maple syrup
- 2 tablespoons Dijon mustard
- 1 tablespoon apple cider vinegar
- 1/2 teaspoon ground cloves or cinnamon
Mix all ingredients in a small bowl. If the mixture is too thick, add a splash of orange juice or water. Brush it generously over the ham before the final roasting stage.
You can also experiment with other flavors. Try adding pineapple juice, bourbon, or a pinch of cayenne for heat. The key is to apply the glaze when the ham is almost done, so the sugars don’t burn.
Resting And Carving The Ham
Once the ham reaches 140°F, remove it from the oven. Let it rest for 15 to 20 minutes before carving. Resting allows the juices to redistribute, making each slice tender and moist.
To carve, place the ham on a cutting board. Use a sharp knife to cut along the spiral cuts, separating the slices. The bone will be in the center, so work around it. Serve the slices on a warm platter.
If you have leftovers, store them in an airtight container in the fridge for up to five days. You can also freeze slices for up to two months.
Common Mistakes To Avoid
Even experienced cooks can make errors with spiral ham. Here are the most common pitfalls and how to avoid them:
- Overcooking: Ham is already cooked, so you only need to reheat it. High heat or long cooking times dry it out.
- Skipping the foil: Without foil, the ham loses moisture and becomes tough. Always cover it for most of the cooking time.
- Not using a thermometer: Guessing the temperature is risky. A meat thermometer ensures accuracy.
- Applying glaze too early: Glaze burns easily. Add it only in the last 20 minutes of cooking.
Another mistake is forgetting to let the ham rest. Cutting into it immediately causes juices to run out, leaving dry meat. Patience pays off here.
Adjusting Cooking Time For Different Sizes
Not all spiral hams are the same size. Use these guidelines to adjust your cooking time:
- 5 to 7 pounds: Cook for about 1 hour to 1 hour 30 minutes at 325°F, then glaze and finish.
- 8 to 10 pounds: Cook for 1 hour 30 minutes to 2 hours, then glaze.
- 11 to 14 pounds: Cook for 2 hours to 2 hours 30 minutes, then glaze.
Always rely on the internal temperature, not just the clock. The ham is ready when it hits 140°F in the thickest part.
Serving Suggestions And Side Dishes
A bone-in spiral ham pairs well with many sides. Consider these classic options:
- Scalloped potatoes or mashed potatoes
- Roasted vegetables like carrots, green beans, or Brussels sprouts
- Fresh salad with a tangy vinaigrette
- Dinner rolls or cornbread
For a sweet contrast, serve the ham with a fruit chutney or cranberry sauce. The saltiness of the ham balances the sweetness of the fruit.
Leftover ham can be used in soups, sandwiches, or omelets. Dice it up and add to mac and cheese for a quick meal.
Storing And Reheating Leftovers
Proper storage keeps your ham safe and tasty. Wrap leftover slices tightly in plastic wrap or aluminum foil, then place them in a resealable bag. Refrigerate for up to five days.
To reheat, place slices in a skillet with a splash of water or broth. Cover and warm over low heat for a few minutes. You can also microwave them, but this can dry them out.
For larger portions, reheat in a 300°F oven, covered with foil, until warmed through. Add a little liquid to the pan to create steam.
Frequently Asked Questions
Can I cook a bone-in spiral ham without a glaze?
Yes, you can. The ham will still be moist and flavorful, but it will lack the caramelized crust. If you skip the glaze, consider brushing it with butter or honey for extra moisture.
How do I know when the ham is done?
Use a meat thermometer. Insert it into the thickest part of the ham, away from the bone. The internal temperature should be 140°F for fully cooked ham.
Should I score the ham before cooking?
Spiral hams are already sliced, so scoring is not necessary. If you have a non-spiral ham, scoring helps the glaze penetrate, but for spiral cuts, it is redundant.
Can I cook the ham in a slow cooker?
Yes, but it is not ideal for spiral hams. The slices may fall apart. If you use a slow cooker, keep the ham whole and cook on low for 4 to 6 hours, then glaze under the broiler.
What if my ham is too salty?
Soak the ham in cold water for 30 minutes before cooking. This draws out some of the salt. Pat it dry before placing it in the oven.
Now you have all the information you need to cook a perfect bone-in spiral ham. Follow these steps, and you will serve a beautiful, juicy ham that impresses everyone at the table. Enjoy the process and the delicious results.
