Holiday cooking can get chaotic fast when everything is competing for oven space, and this crockpot holiday glazed ham solves that problem beautifully by freeing up your oven entirely for sides, casseroles, or dessert. The slow cooker does all the work here, gently warming the ham through while a sweet, sticky glaze caramelizes right on top, resulting in tender, melt-in-your-mouth slices every time.
Using a slow cooker for ham isn’t just a space-saving trick — it genuinely produces a wonderfully moist result, since the gentle, even heat keeps the ham from drying out the way it sometimes can in a hot oven, especially if it’s left in even a few minutes too long. The glaze, built from a classic combination of brown sugar, honey, and a bit of mustard, builds into a sticky, caramelized coating as it cooks alongside the ham.
This is a genuinely low-stress way to serve a beautiful holiday main dish, whether it’s for a smaller gathering or as a backup protein alongside a big turkey spread. Once it’s in the slow cooker, it mostly takes care of itself, leaving you free to focus on everything else on the holiday table.

Ingredient Notes
A pre-cooked, bone-in spiral-cut ham is the easiest option for this recipe, since it’s already fully cooked and just needs to be warmed through and glazed, and the spiral cuts help the glaze reach every layer of meat. Choose a ham that will fit in your slow cooker with the lid closing properly, which may mean selecting a smaller ham than you’d use for oven roasting.
For the glaze, a combination of brown sugar, honey, Dijon mustard, and a splash of apple cider vinegar creates that classic sweet-and-tangy holiday ham flavor. A bit of ground cloves or cinnamon can be added for a warmer, more traditional holiday spice note if you’d like.
Since the ham is already fully cooked, the goal in the slow cooker is really just to warm it through gently while the glaze caramelizes, rather than actually cooking raw meat, which means there’s more flexibility in timing than with a raw protein. Basting the ham periodically with the glaze as it cooks helps build a deeper, more caramelized coating by the time it’s ready to serve.

Step-by-Step Instructions
- Prepare the slow cooker. Place the spiral-cut ham cut-side down in the slow cooker, adding a small amount of water or apple juice to the bottom to help keep the environment moist as it warms. Tip: cut-side down helps the ham retain more moisture as it heats, rather than drying out along the exposed cut edges.
- Make the glaze. Whisk together the brown sugar, honey, Dijon mustard, apple cider vinegar, and any warm spices you’re using in a small bowl until well combined.
- Apply the first layer of glaze. Brush about a third of the glaze mixture over the ham, working it into the spiral cuts as best you can.
- Cook low and slow. Cover and cook on LOW for 4–5 hours, or until the ham is heated through to an internal temperature of at least 140°F, basting with more of the glaze every hour or so. Tip: since the ham is already fully cooked, the goal here is gentle reheating and glaze caramelization, not cooking raw meat, so there’s some flexibility in exact timing depending on the size of your ham.
- Apply the final glaze layer. About 30 minutes before serving, brush the remaining glaze over the ham, letting it continue to warm and caramelize slightly. Tip: reserving some glaze for this final step gives you a glossy, freshly-glazed appearance right before serving.
- Rest and serve. Let the ham rest for about 10 minutes before slicing, then serve with any extra glaze from the bottom of the slow cooker spooned over the top.

Storage & Reheating
Leftover ham keeps well in an airtight container in the fridge for up to 5 days, making it a great option for sandwiches, soups, or casseroles throughout the week after a holiday gathering. Reheat gently in a low oven (around 275°F) covered with foil, or in the microwave in short bursts, to avoid drying it out further.
This ham freezes very well for up to 2–3 months, making it easy to save leftovers for later use. Slice or portion it before freezing so you can thaw only what you need for future meals.
Budget Note
The cost of this recipe varies significantly depending on the size and quality of ham purchased, but ham is often one of the more affordable holiday centerpiece options compared to other large cuts of meat, especially when purchased on sale around major holidays. Making your own glaze from pantry staples rather than buying a pre-made glaze packet also helps keep costs down.
Variations to Try
Pineapple glazed version: Add pineapple juice to the glaze mixture and arrange pineapple rings and maraschino cherries over the ham before cooking for a classic, retro-style presentation.
Maple bourbon version: Swap some of the honey for maple syrup and add a splash of bourbon to the glaze for a deeper, more complex holiday flavor.
Spicy glazed version: Add a pinch of cayenne pepper or a few dashes of hot sauce to the glaze for a sweet-and-spicy twist on the classic combination.
Meal-prep friendly: Slice and portion leftover ham into containers for quick lunches, sandwiches, or additions to soups and casseroles throughout the following week.
Frequently Asked Questions
Do I need to use a spiral-cut ham specifically? A spiral-cut ham makes it easiest for the glaze to reach throughout the meat and for slicing at serving time, but a regular bone-in ham can also be used, just baste extra thoroughly since the glaze won’t penetrate as deeply into the cuts.
How do I know when the ham is done? Since most hams are pre-cooked, you’re really just warming it through to a safe serving temperature of at least 140°F, which you can check with a meat thermometer inserted into the thickest part of the ham.
Can I make the glaze ahead of time? Yes — the glaze can be mixed a few days ahead and stored in the fridge, making it one less thing to prepare on a busy holiday cooking day.
What size ham fits in a slow cooker? This depends on your specific slow cooker size, but generally a ham in the 5–7 pound range fits well in a standard 6-quart slow cooker; always check that the lid closes properly before starting.
Is this recipe spicy? No, this is a classic sweet holiday ham as written — a pinch of cayenne or a few dashes of hot sauce in the glaze is an easy way to add some heat if you’d like a twist on the traditional flavor.
