Put diced cooked ham in the slow cooker with 3 other secret ingredients to get a meal so fantastic your potluck buddies will be begging for more.

This 4-ingredient slow cooker potluck ham is my go-to when I’ve promised to bring a main dish but know I’ll be racing in from work with about five minutes to spare. It starts with a big pile of diced cooked ham in the bottom of the slow cooker and gets transformed with just three other “secret” pantry ingredients into something sweet, savory, and totally addictive. Think of it as a cross between glazed ham and a hearty ham main dish—perfect for potlucks, game days, or those nights when you just want the slow cooker to do the work while you handle everything else on your to-do list.

Serve this slow cooker potluck ham straight from the crock on warm with a big spoon for self-serve ease. It’s fantastic over fluffy white or brown rice, buttered egg noodles, or mashed potatoes to soak up the sweet-savory glaze. For a potluck, I like to set it out with soft dinner rolls or slider buns so people can make little ham sandwiches. Round out the meal with simple sides like a green salad, coleslaw, roasted veggies, or a veggie tray. Leftovers are great stirred into scrambled eggs, omelets, or mac and cheese for an easy next-day meal.

Servings: 6-8

4 cups diced cooked ham (about 1 1/2 pounds), fat trimmed if needed

Place the diced cooked ham in an even layer in the bottom of a 4- to 6-quart slow cooker. It should look like a big pile of ham cubes covering the base of the crock.

In a medium bowl, stir together the pineapple tidbits with a few spoonfuls of their juice, the brown sugar, and the Dijon mustard until the sugar is mostly dissolved and everything is well combined.

Pour the pineapple-mustard mixture evenly over the diced ham in the slow cooker, trying to cover as much of the ham as possible. Use a spoon to gently stir just once or twice so the sauce can work its way between the ham pieces without packing them down too much.

Cover the slow cooker with the lid and cook on LOW for 3 to 4 hours, or on HIGH for 1 1/2 to 2 hours, until the ham is heated through and the sauce is bubbly and slightly thickened. Give it a gentle stir once about halfway through if you’re nearby, but it’s not mandatory.

Once hot, taste the sauce and adjust if needed: add a pinch of salt if your ham is on the mild side, or a spoonful of extra mustard if you want more tang. Switch the slow cooker to WARM for serving at a potluck so it stays hot and safe while people help themselves.

Serve the ham and plenty of the sweet-savory sauce over rice, potatoes, or in rolls. Stir occasionally if it sits on WARM for more than an hour so the sauce stays evenly distributed and the edges don’t dry out.

For a little smoky heat, add 1/4 teaspoon crushed red pepper flakes or a few dashes of hot sauce to the pineapple mixture before pouring it over the ham. If you prefer a more classic holiday-glazed flavor, swap the Dijon for honey mustard and add 1/2 teaspoon ground cinnamon. You can also use maple syrup in place of half the brown sugar for a deeper, cozy sweetness. If your ham is very salty, rinse the diced pieces briefly under cool water and pat dry before adding to the slow cooker, and consider using pineapple tidbits packed in juice (not heavy syrup) to keep the dish from becoming too sweet. For a thicker, stickier glaze, remove the lid for the last 20–30 minutes of cooking on HIGH and let some liquid evaporate, stirring occasionally. Food safety tips: Always start with fully cooked ham that has been refrigerated properly and is within its use-by date. Keep the ham refrigerated until you’re ready to cook, and do not leave it at room temperature for more than 2 hours total (including potluck serving time). When serving at a gathering, keep the slow cooker on WARM so the ham stays at a safe temperature (above 140°F/60°C). Refrigerate leftovers within 2 hours in shallow containers and reheat to at least 165°F before eating.
