This slow cooker 4-ingredient brown sugar ham is the kind of set-it-and-forget-it main dish that makes holidays and Sunday dinners feel special without making you feel chained to the kitchen. You literally pack brown sugar all over a spiral-sliced ham, tuck in just two more simple ingredients, and let the slow cooker do the work. By dinnertime, you’ve got tender, sweet-and-savory slices that everyone reaches for first, plus plenty of juices for spooning over the top. It’s a very Midwestern, potluck-friendly kind of recipe—no fuss, no fancy steps, just dependable comfort food that always gets recipe requests.
Serve this brown sugar ham with classic comfort sides: mashed or scalloped potatoes, green beans, roasted carrots, or a simple tossed salad. Warm dinner rolls or biscuits are perfect for catching the extra glaze. For a family-style spread, I like to add a fruit salad or applesauce for a little sweetness on the plate. Leftovers are wonderful in ham and cheese sliders, omelets, or stirred into a pot of bean soup the next day.
Slow Cooker Brown Sugar Spiral Ham
Servings: 10-12

Ingredients
1 fully cooked spiral-sliced ham, 8–10 pounds
2 cups packed light or dark brown sugar, divided
1/2 cup pineapple juice or apple juice
2 tablespoons Dijon mustard or yellow mustard
Directions
Set your slow cooker on the counter and make sure the insert is dry and in place. Unwrap the spiral ham, discarding any plastic disk on the bone and any glaze packet that came with it.
Pour the pineapple or apple juice into the bottom of the slow cooker. This gives the ham moisture and helps create flavorful cooking juices.
In a small bowl, stir together 1 1/2 cups of the brown sugar and the Dijon or yellow mustard until it forms a thick, sandy paste.
Place the spiral ham cut-side down into the slow cooker. If it’s a tight fit, you can trim a small piece from the bottom or side so the lid will close fully.
Using clean, dry hands, pack the brown sugar–mustard mixture all over the top and sides of the ham, pressing it gently into the spiral slices so it sticks. Sprinkle the remaining 1/2 cup brown sugar over any bare spots and on top for extra caramelization.
Cover the slow cooker with the lid, making sure it fits snugly. Cook on LOW for 4–6 hours, or until the ham is heated through and very tender. Baste the ham with the cooking juices once or twice during the last hour if you’re nearby, but it will still turn out well if you need to leave it alone.
Once heated through, carefully lift the ham out of the slow cooker and transfer it to a cutting board or serving platter. Let it rest for about 10 minutes so the slices hold together better.
Stir the juices in the bottom of the slow cooker. If you’d like them a bit thicker, you can simmer them in a small saucepan on the stove for a few minutes until slightly reduced. Spoon the warm juices over the ham before serving, and offer extra at the table.
Variations & Tips
For a milder flavor, use yellow mustard instead of Dijon, or cut the mustard in half for kids who are sensitive to tangy flavors. If your family loves a stronger sweetness, add 1–2 tablespoons of maple syrup or honey to the brown sugar mixture. For a hint of warm spice, sprinkle in 1/2 teaspoon ground cinnamon or a pinch of ground cloves with the brown sugar. You can swap apple cider for the juice in the bottom of the slow cooker for a cozy fall flavor. If your ham is smaller (around 5–6 pounds), reduce the cook time to about 3–4 hours on LOW and keep an eye on it so it doesn’t dry out. For crispier edges, you can place the cooked ham under the broiler on a foil-lined pan for 3–5 minutes, basting with some of the juices, just until the sugar on top bubbles. Leftovers freeze well in small portions for quick weeknight dinners, grilled cheese with ham, or to stir into casseroles and soups.
