A spiral ham in the slow cooker stays succulent and requires little hands-on attention. If you have been wondering how to cook a spiral ham in the slow cooker, you have come to the right place. This method keeps the meat moist and the glaze caramelized without drying out the slices.
You do not need to be a chef to pull this off. The slow cooker does all the heavy lifting, leaving you free to prepare sides or set the table. Let us walk through every step, from choosing the ham to serving it perfectly.
Why Use A Slow Cooker For Spiral Ham
Oven baking can dry out a pre-sliced ham. The slow cooker traps steam and heat, keeping each slice tender. You also free up oven space for other dishes, which is a huge win during holidays or big dinners.
The low, steady temperature prevents the ham from overcooking. Plus, the glaze gets a chance to soak into the cuts without burning. It is a set-it-and-forget-it approach that delivers consistent results.
What You Will Need
Before you start, gather these items:
- One spiral-cut ham (bone-in or boneless, 6–10 pounds)
- A slow cooker large enough to hold the ham (6–7 quarts works best)
- Brown sugar, honey, or maple syrup for the glaze
- Dijon mustard or whole-grain mustard
- Optional: pineapple juice, apple cider vinegar, or orange juice
- Aluminum foil (to shape a tent if needed)
- Meat thermometer
Most spiral hams come pre-cooked, so you are really just reheating and glazing. Check the label to be sure. If it says “cook before eating,” follow the same steps but ensure it reaches 145°F internally.
How To Cook A Spiral Ham In The Slow Cooker
This is the main section where you get the exact process. Follow these steps closely for the best outcome.
Step 1: Prepare The Ham
Take the ham out of the fridge about 30 minutes before cooking. This lets it come closer to room temperature, which helps it heat evenly. Remove any plastic packaging, netting, or plastic cap. Do not remove the natural skin or fat cap—it protects the meat.
Pat the ham dry with paper towels. If there is a small plastic disk covering the bone, take that off too. Place the ham flat-side down in the slow cooker. If it does not fit, you can trim a bit of the bottom or cut it in half, but that is rare with a standard 6-quart cooker.
Step 2: Make The Glaze
In a small bowl, mix together:
- 1/2 cup brown sugar (packed)
- 1/4 cup honey or maple syrup
- 2 tablespoons Dijon mustard
- 1 tablespoon apple cider vinegar
Stir until smooth. You can add a splash of pineapple juice or orange juice for extra flavor. Taste it—if you want it sweeter, add more sugar. If you want tang, add more mustard or vinegar.
Step 3: Apply The Glaze
Brush about half of the glaze over the entire ham, making sure it gets into the spiral cuts. Use a silicone brush or a spoon to work it in. Reserve the other half for later.
If you want a sticky, caramelized finish, do not pour all the glaze at once. Layering it halfway through cooking gives a better result.
Step 4: Add Liquid To The Slow Cooker
Pour about 1/2 cup of water, apple juice, or chicken broth into the bottom of the slow cooker. Do not submerge the ham—just add enough to create steam. The ham will release its own juices as it cooks, so you do not need much liquid.
Cover the slow cooker with the lid. If the lid does not fit snugly because the ham is tall, make a foil tent and place it over the top before closing the lid. This traps heat without pressing down on the ham.
Step 5: Cook On Low
Set the slow cooker to low heat. Cooking time depends on the size of the ham:
- 6–8 pounds: 4 to 5 hours
- 8–10 pounds: 5 to 6 hours
- 10+ pounds: 6 to 7 hours
Do not cook on high—it can make the outer slices dry while the center stays cold. Low and slow is the key. Check the internal temperature with a meat thermometer after 4 hours. It should reach 140°F for a fully cooked ham, or 145°F if it is raw.
Step 6: Glaze Again Halfway
About halfway through cooking, open the lid and brush the remaining glaze over the ham. This adds a second layer of flavor and helps build a sticky coating. Work quickly so the cooker does not lose too much heat.
If you see that the liquid level is low, add another 1/4 cup of water or juice. The ham should not sit in deep liquid, but there should be enough to keep the bottom moist.
Step 7: Rest And Serve
Once the ham reaches the right temperature, turn off the slow cooker. Let the ham rest in the cooker with the lid off for about 10–15 minutes. This allows the juices to redistribute and makes slicing easier.
Carefully lift the ham out using tongs or two large forks. Place it on a cutting board. The spiral cuts mean you can simply pull the slices apart with a fork. Arrange them on a platter and spoon some of the cooking liquid over the top for extra moisture.
If you want a more caramelized finish, you can broil the ham for 3–5 minutes after it comes out of the slow cooker. Place the slices on a baking sheet, brush with glaze, and broil until bubbly. Watch closely so it does not burn.
Tips For The Best Slow Cooker Spiral Ham
Do Not Overcook
Spiral ham is already cooked, so you are just reheating it. Overcooking makes the meat stringy and dry. Stick to the time ranges above and use a thermometer to be sure.
Use A Liner For Easy Cleanup
Slow cooker liners are a lifesaver. They prevent the sticky glaze from burning onto the ceramic insert. Just lift the liner out after cooking and throw it away. No scrubbing required.
Keep The Fat Cap On
The fat cap adds flavor and moisture. If you trim it off, the ham will dry out faster. Leave it on during cooking and remove it before serving if you prefer lean meat.
Add Aromatics
For extra depth, place a few sprigs of rosemary, thyme, or bay leaves in the slow cooker before adding the ham. You can also toss in a cinnamon stick or star anise for a warm, spiced note.
What To Serve With Spiral Ham
This ham pairs well with classic sides. Consider these options:
- Mashed potatoes or sweet potato casserole
- Green beans almondine or roasted asparagus
- Dinner rolls or cornbread
- Coleslaw or a simple garden salad
- Scalloped potatoes or macaroni and cheese
The leftover ham bone is perfect for making soup. Save it along with the cooking liquid to make a rich broth for split pea or bean soup.
Storing And Reheating Leftovers
Leftover ham keeps well in the fridge for up to 5 days. Store it in an airtight container or wrap it tightly in foil. To reheat, place slices in a skillet with a splash of water or broth and warm over medium heat. You can also microwave them in 30-second bursts, but the texture may suffer.
For longer storage, freeze the ham in portions. Wrap each portion in plastic wrap, then foil, and place in a freezer bag. It will stay good for up to 3 months. Thaw in the fridge overnight before reheating.
Frequently Asked Questions
Can I Cook A Frozen Spiral Ham In The Slow Cooker?
It is not recommended. Thaw the ham completely in the fridge first, which can take 24–48 hours depending on size. Cooking from frozen leads to uneven heating and may keep the center too cold for too long.
Do I Need To Add Water To The Slow Cooker?
Yes, a small amount of liquid is needed to create steam. About 1/2 cup of water, juice, or broth is enough. The ham will release its own juices, so you do not need to cover it completely.
Can I Use A Glaze Packet That Comes With The Ham?
You can, but homemade glaze usually tastes better and lets you control the sweetness. If you use the packet, mix it with a little water or juice before applying.
How Do I Prevent The Ham From Drying Out?
Cook on low heat, keep the fat cap on, and do not overcook. Basting with glaze halfway through also helps lock in moisture. Using a meat thermometer ensures you stop at the right temperature.
Can I Cook The Ham On High Instead Of Low?
Technically yes, but the results are less consistent. High heat can dry out the outer slices and make the glaze burn. Low heat is safer and gives you a more tender ham.
Final Thoughts
Learning how to cook a spiral ham in the slow cooker saves time and delivers a juicy, flavorful centerpiece. The method is forgiving, so even if you forget to glaze it halfway, the ham will still taste great. Just remember to use low heat, add a little liquid, and check the temperature before serving.
This dish works for Easter, Christmas, Thanksgiving, or any Sunday dinner. Pair it with your favorite sides, and you have a meal that looks impressive without hours of work. Give it a try, and you will see why the slow cooker is the best tool for spiral ham.
If you have any leftover glaze, drizzle it over the slices before serving. The extra sweetness and tang will make everyone ask for seconds. Enjoy your perfectly cooked ham.
