A 10 pound ham often comes pre-cooked, so reheating it gently prevents dryness. Knowing how to cook a 10 pound ham properly ensures a moist, flavorful centerpiece for your holiday meal or Sunday dinner. This guide walks you through every step, from choosing the right ham to carving it perfectly.
You do not need to be a professional chef to get this right. A few simple techniques and a reliable meat thermometer are all you need. Let us get started.
Choosing The Right Ham For Your Needs
Before you even think about the oven, you need to pick the right ham. Not all hams are created equal. The type you buy affects the cooking time and method.
Bone-In Vs. Boneless Ham
Bone-in hams often have more flavor. The bone helps conduct heat and keeps the meat moist. A bone-in 10 pound ham will serve about 10 to 12 people. Boneless hams are easier to slice but can dry out faster if you are not careful. They serve roughly 15 to 20 people because there is no bone weight.
Spiral-Sliced Vs. Whole Ham
Spiral-sliced hams are pre-cut, making serving very easy. However, they can dry out quicker because the exposed surfaces lose moisture. Whole hams require you to slice them yourself, but they retain moisture better during reheating.
City Ham Vs. Country Ham
Most hams you find in the grocery store are city hams. They are wet-cured and fully cooked. Country hams are dry-cured, saltier, and often require soaking before cooking. For this article, we focus on the common city ham.
How To Cook A 10 Pound Ham
This section covers the standard oven method. It is the most reliable way to reheat a pre-cooked ham without drying it out. Follow these steps closely.
Step 1: Prepare The Ham
Take the ham out of the refrigerator about 1 to 2 hours before cooking. This allows it to come to room temperature slightly. Do not leave it out for more than 2 hours. Remove all packaging materials. Rinse the ham under cool water and pat it dry with paper towels.
If your ham has a plastic disk or cap over the bone, remove that too. Some hams come with a glaze packet. Set that aside for later.
Step 2: Score The Ham (Optional But Recommended)
Scoring the ham helps the glaze penetrate and creates a nice presentation. Use a sharp knife to cut shallow diagonal lines across the fat cap. Make the cuts about 1/4 inch deep. Then cut diagonal lines in the opposite direction to create a diamond pattern.
Step 3: Place The Ham In A Roasting Pan
Use a roasting pan with a rack. The rack keeps the ham off the bottom of the pan. This prevents it from sitting in its own juices and becoming soggy on the bottom. Place the ham fat-side up on the rack. Add about 1 cup of water, apple juice, or chicken broth to the bottom of the pan. This creates steam and keeps the ham moist.
Step 4: Cover And Bake
Cover the roasting pan tightly with aluminum foil. This traps steam and prevents the ham from drying out. Preheat your oven to 325°F (163°C). Place the covered ham in the oven.
For a fully cooked ham, the general rule is to reheat for about 15 to 18 minutes per pound. For a 10 pound ham, that means roughly 2.5 to 3 hours. However, always rely on a meat thermometer, not just time.
Step 5: Apply The Glaze (Last 30 Minutes)
About 30 minutes before the ham is done, remove it from the oven. Increase the oven temperature to 400°F (204°C). Carefully remove the foil. Score the fat if you have not already. Brush the glaze generously over the entire surface.
Return the ham to the oven uncovered. Bake for another 20 to 30 minutes, basting once or twice with the pan juices. The glaze should become sticky and caramelized.
Step 6: Check Internal Temperature
This is the most critical step. Insert an instant-read meat thermometer into the thickest part of the ham, avoiding the bone. The USDA recommends a minimum internal temperature of 140°F (60°C) for reheating pre-cooked ham. If you are using a glaze with sugar, be careful not to burn it. The sugar can scorch quickly.
Step 7: Rest And Carve
Once the ham reaches 140°F, remove it from the oven. Let it rest for 15 to 20 minutes. Resting allows the juices to redistribute. Cover it loosely with foil during this time. After resting, transfer the ham to a cutting board. Carve against the grain for the most tender slices.
Alternative Cooking Methods
The oven is not your only option. Here are two other reliable ways to cook a 10 pound ham.
Slow Cooker Method
This method works best for boneless hams. Cut the ham to fit your slow cooker if needed. Place the ham in the slow cooker. Add 1/2 cup of liquid like pineapple juice or cola. Cover and cook on low for 4 to 6 hours, or on high for 2 to 3 hours. Apply the glaze during the last 30 minutes on high. The ham will be very tender.
Instant Pot Or Pressure Cooker Method
This is the fastest method. Cut the ham to fit inside your Instant Pot. Add 1 cup of water or broth. Place the ham on the trivet. Lock the lid and cook on high pressure for about 10 to 15 minutes per pound. For a 10 pound ham, that is roughly 15 to 20 minutes total. Use a natural pressure release for 10 minutes, then quick release. Finish under the broiler with glaze for 3 to 5 minutes.
Making The Perfect Glaze
A good glaze adds flavor and a beautiful shine. You can use store-bought glaze packets, but homemade is easy and better.
Simple Brown Sugar Glaze
- 1 cup packed brown sugar
- 1/4 cup honey or maple syrup
- 2 tablespoons Dijon mustard
- 1 tablespoon apple cider vinegar
- 1/4 teaspoon ground cloves
Mix all ingredients in a small bowl. Brush onto the ham during the last 30 minutes of cooking.
Pineapple And Cherry Glaze
- 1 cup pineapple juice
- 1/2 cup brown sugar
- 1/4 cup cherry preserves
- 1 tablespoon cornstarch mixed with 2 tablespoons water
Simmer the juice, sugar, and preserves in a saucepan. Whisk in the cornstarch slurry. Cook until thickened. Brush onto the ham.
Common Mistakes To Avoid
Even experienced cooks make errors with ham. Here are the most common ones and how to avoid them.
- Overcooking: A pre-cooked ham only needs reheating. Overcooking makes it dry and tough. Use a thermometer.
- Skipping the rest: Cutting into a hot ham immediately causes juices to run out. Always rest it.
- Not scoring the fat: Without scoring, the glaze slides off. Scoring gives the glaze a place to stick.
- Using too high heat: High heat dries out the exterior before the interior is warm. Stick to 325°F.
- Forgetting the liquid: The liquid in the pan creates steam. Without it, the ham dries out faster.
Storing And Reheating Leftovers
Leftover ham is a gift. You can use it for sandwiches, soups, and casseroles. Store it properly to keep it fresh.
Refrigerating Leftover Ham
Remove the meat from the bone. Wrap it tightly in plastic wrap or aluminum foil. Place it in an airtight container. It will keep in the refrigerator for 3 to 5 days.
Freezing Leftover Ham
Ham freezes well. Slice or cube the meat. Place it in freezer-safe bags or containers. Remove as much air as possible. It will keep for 2 to 3 months. Thaw in the refrigerator overnight before using.
Reheating Leftover Ham
To reheat slices, place them in a skillet with a splash of water or broth. Cover and warm over low heat. You can also microwave slices for 30 seconds. For larger portions, wrap in foil and reheat in a 300°F oven for 10 to 15 minutes.
Frequently Asked Questions
Do I Need To Cook A 10 Pound Ham If It Says “Fully Cooked”?
No, you only need to reheat it to 140°F. Cooking it further will dry it out. The goal is gentle warming.
How Long Does It Take To Cook A 10 Pound Ham At 325°F?
For a fully cooked ham, plan for about 15 to 18 minutes per pound. That is roughly 2.5 to 3 hours total. Always check the internal temperature.
Can I Cook A 10 Pound Ham Without A Glaze?
Yes, you can. The ham will still be good. However, a glaze adds sweetness and helps keep the surface moist. If you skip it, baste the ham with pan juices every 30 minutes.
What Is The Best Liquid To Put In The Bottom Of The Pan?
Water works fine. Apple juice, pineapple juice, or chicken broth add more flavor. Avoid sugary sodas as they can burn and create a mess.
Should I Cover A Ham While Baking?
Yes, cover it with foil for most of the cooking time. Uncover it only for the last 30 minutes when you apply the glaze. This keeps the ham moist.
