Made with a fully cooked ham, cola, brown sugar, Dijon mustard, and a few simple seasonings, this easy recipe creates a sweet, savory glaze that coats every slice.
The slow cooker does most of the work, allowing the ham to warm slowly while absorbing the rich flavors of the cola and brown sugar mixture. The result is juicy, tender ham with a glossy glaze and a wonderful balance of sweetness and savory flavor. Best of all, this recipe requires very little preparation, making it an excellent choice when you want an impressive meal without spending hours in the kitchen.
Why You’ll Love This Slow Cooker Ham
There are many reasons to make this cola brown sugar ham part of your regular dinner rotation. First, it is incredibly easy to prepare. Simply place the ham in the slow cooker, mix the glaze ingredients, pour the mixture over the meat, and let everything cook until heated through and flavorful.
The combination of cola and brown sugar creates a rich, caramel-like flavor that pairs beautifully with the natural saltiness of ham. Dijon mustard adds a gentle tang, while a little garlic and black pepper provide extra depth.
Another advantage is that the slow cooker keeps the ham moist. Unlike oven cooking, which can sometimes dry out the outer layers, slow cooking in a covered pot helps retain moisture throughout the cooking process.
This recipe is also perfect for entertaining because it frees up your oven for side dishes such as roasted vegetables, casseroles, dinner rolls, and baked potatoes.
Ingredients You’ll Need
This recipe uses simple ingredients that are easy to find at most grocery stores.
- 1 fully cooked bone-in ham, approximately 6–8 pounds
- 1 can (12 ounces) regular cola
- 1 cup packed brown sugar
- 1/4 cup honey
- 2 tablespoons Dijon mustard
- 1 tablespoon apple cider vinegar
- 1 teaspoon garlic powder
- 1/2 teaspoon ground black pepper
- 1/2 teaspoon onion powder
- 1/4 teaspoon ground cloves, optional
- 1 tablespoon cornstarch, optional for thickening the glaze
- 1 tablespoon cold water, if using cornstarch
Choose a ham that fits comfortably inside your slow cooker. A bone-in ham provides excellent flavor, but a boneless fully cooked ham can also be used. If necessary, trim a small amount from the ham or choose a smaller cut so the lid closes properly.
Regular cola is recommended because it provides sweetness and caramel notes. Diet cola can be used, but the glaze may have a slightly different flavor and consistency.
How to Make Slow Cooker Cola Brown Sugar Ham
Step 1: Prepare the Ham
Remove the ham from its packaging and discard any plastic or other wrapping. If the ham comes with a plastic bone guard, remove it before cooking.
Pat the outside dry with paper towels. If the ham has a thick layer of skin, remove excess skin while leaving a thin layer of fat to help protect the meat and add flavor.
If you are using a spiral-cut ham, handle it gently to prevent the slices from separating too much during cooking. For an unsliced ham, you can lightly score the surface fat in a diamond pattern. This allows the glaze to cling to the exterior and gives the finished ham an attractive appearance.
Place the ham inside the slow cooker with the cut side facing down whenever possible. This position helps retain moisture during cooking.
Step 2: Make the Cola Brown Sugar Glaze
In a medium mixing bowl, combine the cola, brown sugar, honey, Dijon mustard, apple cider vinegar, garlic powder, black pepper, onion powder, and ground cloves if desired.
Whisk everything together until the brown sugar begins to dissolve and the ingredients are evenly combined.
The mixture should be sweet, slightly tangy, and aromatic. The mustard and vinegar help balance the sweetness, while the garlic and onion powders add savory flavor.
If you prefer a sweeter glaze, add another tablespoon or two of brown sugar. For a more tangy flavor, increase the apple cider vinegar slightly.
Step 3: Pour the Glaze Over the Ham
Pour the cola mixture evenly over the ham, allowing some of the liquid to collect around the bottom of the slow cooker.
Use a spoon to spread some of the brown sugar mixture over the top and sides of the meat.
If you are using a large ham, do not worry if the glaze does not completely cover it. The covered slow cooker traps steam, and the liquid will help keep the ham moist as it warms.
Place the lid securely on the slow cooker.
Step 4: Cook the Ham Slowly
Cook the ham on LOW for approximately 4–6 hours, depending on its size, shape, starting temperature, and the manufacturer’s instructions. Smaller hams may heat more quickly, while larger cuts may require additional time.
Because the ham is already fully cooked, the goal is to reheat it gently without drying it out.
Avoid lifting the lid repeatedly, as this releases heat and can extend the cooking time.
For food safety, check the internal temperature with a meat thermometer in the thickest part of the ham, avoiding the bone. USDA guidance recommends reheating fully cooked ham packaged at a USDA-inspected plant to 140°F, while other fully cooked ham products may require reheating to 165°F. Follow the package instructions for your particular ham.
If your ham is labeled fresh or uncooked, this recipe’s reheating instructions do not apply; it must be cooked according to safe temperature guidance for raw pork.
Step 5: Baste the Ham
About halfway through the cooking time, carefully spoon some of the warm cola glaze over the exposed surface of the ham.
This step helps distribute the flavor and keeps the exterior moist. If you are using spiral-cut ham, gently spoon the liquid over the slices without pulling them apart.
You can repeat the process once or twice during cooking if desired, but keep the lid closed between bastings.
As the brown sugar dissolves into the cola, the liquid becomes darker and more flavorful, creating a delicious base for the finishing glaze.
Step 6: Thicken the Glaze
Once the ham has reached the appropriate internal temperature, carefully transfer it to a serving platter and loosely cover it with foil.
Pour the cooking liquid into a small saucepan. If it contains excess fat, skim some from the surface.
Bring the liquid to a gentle simmer over medium heat. Let it reduce for approximately 8–12 minutes, stirring occasionally, until it becomes darker and more concentrated.
For a thicker glaze, mix 1 tablespoon of cornstarch with 1 tablespoon of cold water in a small bowl. Whisk this slurry into the simmering liquid and cook for another 1–2 minutes, stirring constantly, until the glaze thickens.
Be careful not to reduce the glaze too much because the brown sugar can become overly thick or burn.
Step 7: Glaze and Serve
Brush or spoon the warm cola brown sugar glaze over the ham.
If you want to serve the ham in slices, cut it into even portions and arrange them on a platter. Spoon additional glaze over the slices just before serving.
For a beautiful presentation, garnish with fresh parsley, orange slices, or a few sprigs of rosemary.
Serve the ham while warm, with extra glaze on the side so everyone can add as much as they like.
Tips for the Best Cola Brown Sugar Ham
Choose the Right Ham
A fully cooked bone-in ham is an excellent option because it retains moisture and offers plenty of flavor. However, make sure it fits inside your slow cooker with the lid completely closed.
If your ham is too large, select a smaller cut rather than forcing the lid shut.
Use Regular Cola
Regular cola provides the sugar needed to create a rich, caramel-like glaze. Its flavor complements the brown sugar and balances the salty taste of the ham.
You can experiment with other cola brands, but avoid using flavored varieties unless you specifically want those additional flavors.
Avoid Overcooking
Since most hams used for this recipe are already cooked, excessive heating can make the meat dry or stringy.
Check the temperature before the end of the estimated cooking time, particularly if you are using a smaller ham or a spiral-cut variety.
Make the Glaze Extra Flavorful
For a deeper flavor, add a small amount of ground cloves, cinnamon, or smoked paprika. Orange zest can also provide a bright citrus note that pairs wonderfully with the sweetness of the glaze.
Start with small quantities so the spices do not overpower the natural flavor of the ham.
Finish the Glaze Separately
The liquid in the slow cooker may be thin after cooking. Reducing it in a saucepan concentrates the flavors and creates a more attractive glaze.
This simple finishing step makes the ham look glossy and helps the sauce cling to every slice.
What to Serve with Cola Brown Sugar Ham
This sweet and savory ham pairs well with a wide variety of side dishes.
- Mashed potatoes: Creamy mashed potatoes are perfect for soaking up the rich glaze.
- Roasted green beans: Their fresh, slightly crisp texture balances the sweetness of the ham.
- Macaroni and cheese: A creamy, cheesy casserole makes the meal comforting and satisfying.
- Dinner rolls: Soft rolls are ideal for serving alongside the ham or making sandwiches with leftovers.
- Roasted carrots: Their natural sweetness complements the brown sugar glaze.
- Scalloped potatoes: Thinly sliced potatoes baked in a creamy sauce make an excellent holiday side.
- Fresh salad: A crisp green salad with a tangy dressing adds freshness to the plate.
For a holiday meal, consider serving the ham with mashed potatoes, roasted carrots, green beans, and warm dinner rolls.
Variations to Try
Pineapple Cola Brown Sugar Ham
Add several pineapple rings around the ham before cooking. You can also add a few tablespoons of pineapple juice to the glaze. The fruit provides a sweet, tropical flavor that pairs beautifully with the cola.
Spicy Brown Sugar Ham
For a little heat, add 1/4 teaspoon of cayenne pepper or a teaspoon of hot sauce to the glaze. The gentle spice balances the sweetness without overpowering the meat.
Maple Cola Ham
Replace the honey with pure maple syrup for a deeper, woodsy sweetness. Maple syrup works especially well with bone-in ham and warm spices.
Orange Brown Sugar Ham
Add the zest of one orange and 2 tablespoons of fresh orange juice to the cola mixture. The citrus flavor brightens the glaze and makes the dish especially suitable for festive dinners.
Garlic Herb Cola Ham
For a slightly more savory version, add extra garlic powder, a little dried thyme, and a pinch of rosemary. Reduce the brown sugar slightly if you prefer a less sweet glaze.
How to Store Leftovers
Allow leftover ham to cool slightly, then refrigerate it promptly in shallow, airtight containers. Do not leave cooked ham at room temperature for more than two hours, or one hour when the temperature is above 90°F.
Refrigerate leftovers at 40°F or below and use them within 3–4 days. Store the glaze separately or spoon a little over the sliced ham to help prevent it from drying out.
To freeze, wrap individual portions tightly or place them in freezer-safe containers. Label each container with the date and use the ham within approximately 2–3 months for the best quality.
Thaw frozen ham in the refrigerator before reheating. Warm leftovers to an internal temperature of 165°F, adding a little reserved glaze or water to maintain moisture.
Frequently Asked Questions
Can I use a boneless ham?
Yes. A boneless fully cooked ham works well and is often easier to slice. Because boneless hams vary in size and shape, check the temperature early to avoid overheating.
Can I cook this ham on HIGH?
LOW is generally preferable because gentle heating helps maintain moisture. If you must use HIGH, follow the ham manufacturer’s instructions and monitor the internal temperature carefully. The cooking time will vary according to the size of the ham and the appliance.
Do I need to add water?
No additional water is usually necessary. The cola provides liquid for the glaze, and the ham releases some moisture as it warms.
Can I prepare the glaze ahead of time?
Yes. Mix the glaze ingredients up to two days in advance and refrigerate them in a covered container. Stir well before using.
Can I make the ham without honey?
Absolutely. Replace the honey with an equal amount of brown sugar or maple syrup. The final flavor will be slightly different, but the recipe will still be delicious.
How do I know when the ham is ready?
Use a meat thermometer to check the thickest portion without touching the bone. Follow the package’s reheating directions and the appropriate safe internal temperature for your specific ham.
