There are holiday hams that require hours of basting, complex glaze recipes, and constant attention. And then there’s this Slow Cooker 3-Ingredient Cola Ham — the kind of ham that practically makes itself. A fully cooked ham, brown sugar, and cola — that’s all it takes to create a sweet, sticky, caramelized masterpiece that will be the star of your Easter, Christmas, or Sunday dinner table.
The cola does double duty: it adds sweetness and complexity, and its acidity helps tenderize the meat. The brown sugar creates a gorgeous, sticky, candy-like glaze. And the slow cooker does all the work, keeping the ham moist and juicy while the flavors meld.
This is the ultimate set-it-and-forget-it holiday ham. No oven space required (freeing up room for other dishes), no basting, no fuss. Serve it with your favorite sides, and watch it disappear.

Ingredient Notes
What kind of ham? A fully cooked bone-in or boneless ham works perfectly. Bone-in ham has more flavor; boneless is easier to slice. Do not use sliced ham — it will fall apart. Spiral-cut hams work, but they may be more delicate.
Why not diet cola? Diet sodas contain artificial sweeteners that don’t caramelize properly and can leave a strange aftertaste when cooked down. Use regular cola — Coca-Cola, Pepsi, or any store brand.
What kind of brown sugar? Light brown sugar provides a mild, caramel-like sweetness. Dark brown sugar has more molasses and a deeper, richer flavor. Both work beautifully.
Do I need to add any other seasonings? The cola and brown sugar create a perfect sweet glaze. Some people like to add a pinch of cloves or cinnamon, but it’s not necessary.
Do I need to score the ham? Scoring the ham (cutting a diamond pattern into the fat) helps the glaze penetrate and creates a beautiful presentation. It’s optional but recommended.
Do I need to grease the slow cooker? No. The ham releases enough juices to prevent sticking.
What size slow cooker? A 6- to 7-quart slow cooker works best for a 4–6 pound ham.
Step-by-Step Instructions
Step 1: Prep the Ham
Pat the 4 to 6 pound fully cooked ham dry with paper towels. If desired, score the fat in a diamond pattern with a sharp knife (about ¼ inch deep).
Place the ham cut-side down in the bowl of a large slow cooker. If it doesn’t quite fit, trim a small piece off the end so the lid can close fully.
Step 2: Add the Brown Sugar
Sprinkle 1 cup of packed brown sugar all over the top and sides of the ham, pressing it lightly so it sticks and forms a loose coating.
Step 3: Add the Cola
Slowly pour 2 cups of cola around the ham into the bottom of the slow cooker, trying not to wash too much of the sugar off the top. The liquid should come at least 1 to 2 inches up the sides of the ham.
Step 4: Cover and Cook
Cover the slow cooker with the lid. Cook on:
-
LOW for 6 to 8 hours, or
-
HIGH for 3 to 4 hours
The ham is ready when it is heated through and very tender. The meat should pull apart easily with a fork and the liquid will look dark, syrupy, and bubbly around the edges.
Step 5: Rest the Ham
Once cooked, carefully transfer the ham to a cutting board, tent it loosely with foil, and let it rest for about 10 minutes. Meanwhile, skim off any excess fat from the surface of the cooking juices in the slow cooker.
Step 6: Glaze the Ham (Optional but Recommended)
Spoon some of the dark cola-brown sugar juices over the ham while it rests to create an extra sticky glaze.
Step 7: Slice and Serve
Slice the ham and serve warm, spooning additional juices from the slow cooker over the top of each portion.
Step 8: Leftovers
Store leftovers in an airtight container in the fridge for up to 4 days, with some of the cooking liquid to keep the meat juicy.
Variations & Tips
Make It with Dr Pepper
Substitute 2 cups of Dr Pepper for the cola. Dr Pepper adds a slightly spicier, more complex sweetness.
Make It with Root Beer
Substitute 2 cups of root beer for the cola. Root beer adds a sweet, vanilla-like note.
Add Cloves
Press 10–15 whole cloves into the scored ham before cooking. Cloves add a classic holiday flavor.
Add Cinnamon
Add 2 cinnamon sticks to the slow cooker. Cinnamon adds warmth and depth.
Add Orange Juice
Add ½ cup of orange juice along with the cola. Orange and ham are a classic pairing.
Make It Spicy
Add ½ teaspoon of red pepper flakes or 1 teaspoon of hot sauce to the cola for a sweet-heat glaze.

Frequently Asked Questions (FAQs)
Do I need to use a fully cooked ham?
Yes. This recipe is designed for a fully cooked ham. If you use a raw ham, it will need to cook much longer and may not be safe.
Can I use a spiral-cut ham?
Yes. Spiral-cut hams work beautifully. Be gentle when transferring so the slices don’t fall apart. The glaze will seep between the slices, adding even more flavor.
Why do I need to trim the ham to fit?
If the ham is too tall for your slow cooker, the lid won’t close properly, and the heat will escape. Trimming a small piece off the end ensures a tight seal.
Why is my glaze too thin?
The ham releases juices as it cooks, which can thin the glaze. To thicken: remove the lid during the last hour of cooking to allow the liquid to reduce, or transfer the liquid to a saucepan and simmer on the stovetop for 10–15 minutes.
Why is my glaze too thick?
Stir in a splash of cola or water, a tablespoon at a time, until it reaches your desired consistency.
What should I serve with this ham?
-
Mashed potatoes – The classic choice
-
Scalloped potatoes – Rich and creamy
-
Green bean casserole – A holiday favorite

-
Deviled eggs – Classic Easter side
Can I double this recipe?
Use a 7- to 8-quart slow cooker for a larger ham (up to 8 pounds). Double the brown sugar and cola proportionally. Cooking time remains the same.

Why This Recipe Works
This three-ingredient recipe is a perfect example of slow cooker magic. Here’s why it works so well:
A fully cooked ham is already tender and flavorful. The slow cooker gently reheats it while allowing the glaze to penetrate.
Brown sugar creates a sweet, caramelized crust. As it cooks, it melts into the cola, creating a thick, sticky glaze.
Cola adds sweetness and complexity (vanilla, cinnamon, citrus notes). The acidity also helps tenderize the meat and balances the sweetness.
The slow cooker provides gentle, even heat that keeps the ham moist. The covered environment traps steam, which prevents drying out.
The result is a ham that’s sweet, sticky, tender, and deeply satisfying — with almost no effort at all.

The slow cooker does all the work. The brown sugar and cola transform into a gorgeous caramelized glaze. The ham stays moist and juicy. And the whole thing comes together with almost no effort.
