There is something about a glazed ham that feels celebratory. It is the centerpiece of Easter brunch, the star of Christmas dinner, and the guest of honor at countless family gatherings. But traditional ham recipes can be intimidating—scoring the fat, studding with cloves, basting every hour, worrying about drying it out. This 3-Ingredient Slow Cooker Brown Sugar Ham takes all of that stress off the table.
The secret is as simple as it gets: a frozen fully cooked ham goes straight into the slow cooker. A sticky, sweet-tangy paste of brown sugar and Dijon mustard is pressed all over the surface. Then you cover it, turn it on, and walk away. Hours later, you return to a ham that is perfectly heated through, beautifully glazed, and surrounded by a rich, savory-sweet jus that tastes like it took hours of careful attention.
This recipe is almost laughably easy, but the results are anything but. The brown sugar caramelizes into a glossy, sticky coating. The Dijon mustard cuts through the sweetness with sharp, tangy brightness. The ham bastes in its own juices, emerging tender, moist, and deeply flavorful. Serve it for a holiday dinner, a Sunday supper, or any time you want to serve something special without any fuss.

3-Ingredient Slow Cooker Brown Sugar Ham
Prep Time: 5 minutes | Cook Time: 6-8 hours on LOW | Resting Time: 15 minutes | Total Time: Approximately 6.5-8.5 hours
Yield: 8-10 servings
Ingredients
-
1 frozen boneless fully cooked ham, about 3-4 pounds
-
1 cup packed light or dark brown sugar
-
2 tablespoons Dijon mustard
Instructions
1. Place the Ham in the Slow Cooker:
Place the completely frozen boneless ham into the bottom of a large slow cooker, flat side down if it has one. It should rest snugly in the insert. Do not add water or broth.
2. Make the Glaze:
In a small bowl, stir together the brown sugar and Dijon mustard until it forms a thick, sandy paste.
3. Coat the Ham:
Sprinkle and press the brown sugar-mustard mixture all over the top and sides of the frozen ham, letting any excess fall around the base of the ham in the slow cooker.
4. Cook:
Cover the slow cooker with the lid and set to LOW. Cook for 6 to 8 hours, or until the ham is heated through to an internal temperature of at least 140°F (60°C) in the center. The ham will thaw first, then slowly baste in its own juices and the melted brown sugar glaze.
5. Rest the Ham:
Once heated through, carefully transfer the ham to a cutting board. Tent loosely with foil and let rest for 10 to 15 minutes so the juices redistribute.
6. Make the Glaze (Optional):
While the ham rests, skim excess fat from the surface of the cooking juices in the slow cooker. If you would like a thicker glaze, ladle some of the liquid into a small saucepan and simmer over medium heat for 5 to 10 minutes until slightly reduced.
7. Slice and Serve:
Slice the ham across the grain into ¼- to ½-inch slices. Serve warm with spoonfuls of the brown sugar-mustard juices or reduced glaze drizzled over the top.
Recipe Notes & Pro Tips
Frozen Ham is Key: Starting with a frozen ham is intentional. As it thaws and cooks slowly, the ham releases juices gradually, creating a flavorful cooking liquid that bastes the meat continuously. A thawed ham may become dry or overcooked in the same time frame.
Do Not Add Liquid: The ham will release plenty of its own juices as it thaws and cooks. Adding water, broth, or any other liquid will dilute the glaze and result in a thinner, less flavorful jus.
Fully Cooked Ham Only: This recipe is designed for fully cooked hams (sometimes labeled “city ham”). The slow cooker simply reheats and glazes the ham. Do not use a raw or “cook before eating” ham, as it requires different handling and higher internal temperatures.
Boneless vs. Bone-In: Boneless ham is easier to slice and fits more easily into most slow cookers. Bone-in ham works as well but may require a larger slow cooker. Ensure the lid can close securely. Bone-in ham may also need slightly longer cooking time.
Internal Temperature: Fully cooked ham needs to reach an internal temperature of 140°F (60°C) to be safely served. Use an instant-read thermometer inserted into the thickest part of the ham, avoiding the center if boneless.
Glaze Consistency: The brown sugar and mustard will melt into the ham drippings, creating a thin, flavorful jus. For a thicker, stickier glaze that clings to the ham, reduce the liquid in a saucepan as directed. You can also brush this reduced glaze over the ham before serving for a more polished look.
Spiral Ham: A frozen spiral-cut ham works beautifully in this recipe. The glaze seeps between the slices, coating every surface. Handle carefully when transferring to prevent the slices from falling apart.
Variations
Honey Mustard Ham: Substitute the brown sugar with 1 cup of honey. Reduce the Dijon mustard to 1 tablespoon. The glaze will be thinner but intensely flavorful.
Maple Brown Sugar Ham: Substitute ½ cup of the brown sugar with ½ cup of pure maple syrup. The maple adds a deeper, more complex sweetness.
Spiced Ham: Add ½ teaspoon of ground cinnamon, ¼ teaspoon of ground cloves, and ¼ teaspoon of ground nutmeg to the brown sugar mixture. These warm spices are classic holiday accompaniments to ham.
Pineapple Brown Sugar Ham: Add 1 cup of pineapple juice to the slow cooker along with the ham. The acidity of the pineapple adds brightness and helps tenderize the meat. For extra flavor, arrange pineapple rings over the ham before cooking.
Coca-Cola Ham: Pour ½ cup of cola (not diet) over the ham before cooking. The sugar in the soda caramelizes and adds depth, while the acidity helps tenderize. This is a classic Southern technique.
Spicy Brown Sugar Ham: Use spicy brown mustard or whole grain mustard in place of Dijon. Add ½ teaspoon of cayenne pepper or red pepper flakes to the glaze for gentle heat.
Serving Suggestions
This ham is a complete centerpiece, but it shines alongside classic sides:
-
Mashed potatoes or sweet potatoes
-
Scalloped potatoes or au gratin potatoes
-
Roasted green beans or Brussels sprouts
-
Creamed spinach or collard greens
-
Macaroni and cheese
-
Dinner rolls or cornbread
-
Cranberry sauce or apple chutney
Leftover ham makes incredible sandwiches on soft rolls with Swiss cheese and a smear of honey mustard. It is also perfect chopped into omelets, quiches, or pasta salads.
Storage & Reheating
Store leftover ham in an airtight container in the refrigerator for up to 5 days. Leftover glaze can be stored separately.
To reheat sliced ham, place in a covered baking dish with a few tablespoons of water or leftover glaze. Warm in a 300°F oven for 10-15 minutes, or microwave individual slices in 30-second bursts.
Ham freezes beautifully for up to 2 months. Slice before freezing for easy portioning. Thaw overnight in the refrigerator before reheating.
Why This Recipe Works
The slow cooker is the ideal vessel for reheating and glazing a fully cooked ham because it provides gentle, even heat without the risk of drying out. Starting with a frozen ham allows it to thaw gradually, releasing juices that combine with the brown sugar and mustard to create a flavorful cooking liquid. The long, low cooking time allows the sugar to caramelize slowly, developing deep, complex sweetness without burning.
The combination of brown sugar and Dijon mustard is a classic for good reason. The brown sugar provides rich, molasses-like sweetness and creates that sticky, glossy glaze. The Dijon mustard adds sharp, tangy brightness that cuts through the richness of the ham and balances the sweetness. Together, they create a flavor profile that is sweet, tangy, savory, and deeply satisfying.
This recipe is proof that you do not need a complicated technique or a long list of ingredients to create something truly special. With three ingredients and a slow cooker, you can produce a holiday-worthy ham that will have everyone asking for the recipe. It is simple, it is brilliant, and it will earn a permanent place in your celebration menu.
