Crockpot Cola Ham

 Crockpot Cola Ham

This is the ultimate set-it-and-forget-it centerpiece—a tender, juicy ham with a sticky-sweet glaze that tastes like you spent all day tending it. The crockpot does the heavy lifting, freeing up your oven and your time.

Yield: 10–14 servings | Prep Time: 15 minutes | Cook Time: 4–6 hours on low or 2–3 hours on high

Why This Recipe Works

The combination of cola and ham might sound unusual, but it’s a classic for good reason. Cola’s high sugar content caramelizes during slow cooking, creating a rich, lacquered glaze, while its phosphoric acid gently tenderizes the meat. The result is a deeply savory-sweet ham that’s more moist and flavorful than oven-roasted versions—and requires almost no hands-on work.

Ingredient Notes

Ham: A 6–8 lb fully cooked spiral-cut ham is ideal. The pre-cut slices allow the glaze to penetrate deep into the meat. Bone-in adds flavor; boneless is easier to carve.

Cola: One 12 oz can of regular cola (full sugar) is best. The sugar is essential for a thick, glossy glaze. Diet cola will not caramelize properly.

Brown Sugar: ¾ cup. Dark brown sugar adds deeper, molasses-like notes; light brown sugar gives a cleaner sweetness.

Honey: ¼ cup adds silkiness and floral sweetness. Maple syrup is a good substitute.

Dijon Mustard: 2 tablespoons. Its sharp tang balances the sweetness and adds savory depth.

Ground Cloves: 1 teaspoon (optional but recommended). A classic pairing with ham that adds warm, aromatic spice.

Ingredients

1 fully cooked spiral-cut ham (6–8 lbs)

1 can (12 oz) regular cola (about 1½ cups)

¾ cup brown sugar (light or dark)

¼ cup honey

2 tablespoons Dijon mustard

1 teaspoon ground cloves (optional)

Instructions

1. Prepare the Crockpot

Lightly coat the inside of a 6-quart or larger slow cooker with cooking spray to prevent the sugary glaze from sticking. Remove any plastic or paper covering from the cut face of the ham.

2. Position the Ham

Place the ham flat-side down in the crockpot. If it's too tall for the lid to close, trim a small section from one end or position it at a slight angle. A small gap in the lid is acceptable, but a fully closed lid yields more consistent results.

3. Mix the Glaze

In a medium bowl, combine the brown sugar, honey, Dijon mustard, and ground cloves (if using). Stir until well blended (the sugar won't fully dissolve yet).

4. Assemble

Pour the cola into the crockpot around the sides of the ham (not directly over the top). Then spoon the brown sugar mixture evenly over the ham, using a spatula to spread it and encourage it to seep between the spiral-cut slices.

5. Slow Cook

Cover and cook on LOW for 4–6 hours or on HIGH for 2–3 hours. The ham is fully cooked; you're reheating it to an internal temperature of 140°F (60°C) . If you're home, baste once or twice by spooning the juices from the bottom over the top to build up the glaze.

6. (Optional but Excellent) Reduce the Glaze

Carefully transfer the ham to a serving platter. Pour the remaining liquid from the crockpot into a small saucepan. Simmer over medium-high heat for 5–10 minutes, stirring occasionally, until thickened to a syrupy glaze. Spoon or brush this over the ham before serving.

7. Rest, Slice, and Serve

Let the ham rest for 5–10 minutes before carving. For a spiral ham, slices will come away easily; run a knife along the bone to release them. Arrange on a platter with extra glaze drizzled on top.

Tips for Best Results

Spiral-cut is key: It allows the glaze to flavor every slice, not just the outside.

Don't drown it: About 2 cups of liquid (the cola) is enough to create steam. Too much will dilute the glaze.

Always reduce the liquid: The leftover juices are thin. Reducing them transforms them into a rich, sticky sauce that's worth the extra few minutes.

Use a meat thermometer: Target 140°F (60°C) at the thickest part, away from the bone.

Let it rest: This allows juices to redistribute, preventing dry slices.

Frequently Asked Questions

Does the ham need to be cooked first?

No. This recipe is designed for store-bought, fully cooked hams. Check the label for "fully cooked" or "heat and serve."

Can I use a boneless ham?

Yes. Boneless ham works perfectly and is easier to carve. The results are nearly identical.

What if my ham doesn't fit?

Try angling it or trimming a small piece from the end. For very large hams (10+ lbs), an 8-quart slow cooker or oven method may be better.

Can I make this in the oven?

Yes. Place ham in a roasting pan, pour cola mixture over it, cover tightly with foil, and bake at 325°F (165°C) for about 15–18 minutes per pound. Uncover for the last 30 minutes, basting every 10 minutes to build the glaze.

How far ahead can I make this?

Cook the ham completely, cool, and refrigerate for up to 2 days. Reheat slices gently in a covered dish at 300°F with a little reserved glaze.

What should I do with leftovers?

Use in sandwiches, breakfast scrambles, split pea soup, creamy pasta, or casseroles. The glaze adds great flavor to any dish.

Variations

Pineapple Ham: Arrange pineapple rings over the ham and add 1 cup pineapple juice to the cola.

Maple Cola Ham: Replace honey with pure maple syrup and slightly reduce the brown sugar.

Spiced Holiday Ham: Add a cinnamon stick, 2–3 whole cloves, and a star anise to the crockpot liquid.

Honey Mustard Glaze Ham: Double the Dijon mustard, increase honey to ⅓ cup, and reduce brown sugar to ½ cup.

Low-Carb Version: Use sugar-free cola and a brown sugar substitute (like Swerve Brown). The glaze will be slightly thinner.

What to Serve With It

The sweet, caramelized glaze pairs beautifully with:

Creamy mashed potatoes – a neutral, buttery base.

Roasted sweet potatoes or sweet potato casserole.

Green beans – sautéed with garlic or as a classic casserole.

Dinner rolls – essential for sopping up extra glaze.

Cranberry sauce – for a sweet-tart contrast.

A simple vinaigrette-dressed salad – to cut through the richness.

Storage

Refrigerator: Cool completely, then store in an airtight container with some glaze spooned over the slices. Keeps for up to 4 days.

Freezer: Wrap individual portions tightly in plastic wrap and foil. Freeze for up to 2 months. Thaw overnight in the refrigerator.

Reheating: Warm gently in a covered skillet over low heat, in a 300°F oven covered with foil, or in the microwave with a splash of water to prevent drying.
