Having come across the concept of cooking gammon in cola numerous times, I finally decided to try it for myself. Everyone loved it and it has become a family favourite. I'm excited to share this easy-to-make recipe with you, and I hope it becomes a hit in your household too!
The process is incredibly simple. Just pop the gammon in the slow cooker (or crockpot), sprinkle it with cinnamon, and pour over the cola. Let it work its magic for a few hours. To add an extra layer of flavour, I like to finish it off with a delightful sticky honey and mustard glaze, roasting it in the oven for a final 30 minutes to achieve that irresistibly crispy top layer of fat.
It's special enough to serve as a Christmas or holiday centrepiece, yet simple enough to make the whole year round. Delicious served hot with these garlic & rosemary hasselback potatoes and Brussels sprouts with bacon or as cold cuts as part of a Boxing Day buffet spread with leftover air fryer pigs in blankets.
Read on to find out how to cook this tasty gammon, including how to adjust the cooking times according to the size of the gammon joint and what to do if the gammon doesn't fit in the slow cooker!

🥘 Ingredients You Will Need
✋ Double check all packaging for allergens ✋
- Gammon Joint - I have tested this recipe using a 2.1kg unsmoked gammon joint. You can use either an unsmoked or smoked joint, the choice is yours. Smoked joints tend to have a stronger flavour and may require a bit of preparation to remove any excess salt. See the section below titled " should I soak gammon before cooking " for more info.
- Coke - A full-fat version of any brand of cola is best to use. I have seen reports about recipes using diet versions not turning out great, due to the artificial chemicals in them like aspartame when heated. I haven't personally tested with a diet version, but the full-fat version works great so stick with that!
- Vegetables - Onion and carrot are added to the slow cooker to use as a trivet to sit the gammon on and also to enhance the flavour of the gammon.
- Cinnamon - Used to add some festive spice to the ham.
- Glaze Ingredients - I have gone traditional here and used runny honey, wholegrain mustard and dark brown sugar mixed to create a sweet and sticky glaze.

🤔 Should I Use Smoked Or Un-Smoked Gammon?
There is no right answer to this, it's all down to your personal taste preferences.
I would decide by how you like your bacon, if you prefer smoked bacon go for a smoked gammon joint and vice versa.
Unsmoked gammon is a lot milder in flavour than smoked which has a delicious smoky flavour but can also be a lot saltier.
🤔 Should I Soak Gammon Before Cooking?
If you have brought a smoked joint and want to take some of the saltiness away, you may want to soak the gammon before cooking it.
Place the raw joint in a large saucepan full of water and soak it overnight in the fridge. Pat it dry with kitchen towel, before placing it in the slow cooker.
You can also boil it for 30 minutes prior to placing it in the slow cooker, remembering to pat dry with kitchen towel afterwards to remove any leftover salt on the surface.
✏️ How to Make - Step-By-Step Instructions
⬇️ Here you will find an overview of how to make the recipe. For full information on ingredients and quantities please see the recipe card at the bottom of the page ⬇️
Step 1: Start by chopping the carrot and onion into large chunks, don't worry about removing the skin, then place them in the bottom of the slow cooker and add the gammon joint on top.
Step 2: Pour enough cola to almost submerge the gammon and sprinkle in the cinnamon. It doesn't matter if you don't use the full 2 litres of cola, just use as much as you need to cover the joint.
Step 3: Cook on low for 4-6 hours or high for 6-8 hours. (depending on your slow cooker) The meat is cooked once it reaches an internal temperature of 145˚F - so use a meat thermometer to check.
Step 4: Once the meat is cooked, remove the gammon from the slow cooker and place it in a roasting tin. ( You can discard the cola juices left in the slow cooker)
Step 5: Remove any string & most of the fat from the top of the joint with a knife. Score the remaining fat with a sharp knife. I like to make a criss-cross pattern but some people like to just score lines,
Step 6: Mix together the glaze ingredients in a small bowl and using a pastry brush, baste the top and sides of the joint with half of the mixture.
Step 7: Roast the ham in a preheated oven for 15 minutes, then pour over the remaining glaze and roast for a further 15 minutes until the fat is nice and crispy.
Delicious served hot or cold.
⭐ Help! My Gammon Won't Fit In The Slow Cooker!
A 2kg gammon joint should fit nicely in a 3.5L slow cooker, but if you are buying a larger joint and find it won't fit in the slow cooker you can easily boil the gammon on a low heat on the hob instead.
I tested this recipe on the hob using a 2kg joint and it took around 2 hours for the gammon to cook, once boiled, simmering on a really low heat in a large saucepan with the lid on. Finish it off in the oven as per the recipe once it is cooked.
🤔 How Long Per Kg Does Gammon Take To Cook In The Slow Cooker?
A 2.1 Kg joint took around 4.5 hours on the high setting to reach the safe internal temperature of 63˚C / 145˚F in my slow cooker.
I really recommend using a meat thermometer to check when meat is cooked. You can pick up them cheaply on Amazon and it will become your new best friend in the kitchen, trust me!
Timings can fluctuate depending on the weight of your gammon and the make and model of your slow cooker, however, you can use the below timings as a rough guide.
- 1kg: 2-4 hours on high / 5-7 on low
- 2kg: 4-6 hours on high / 6-8 on low
- 3kg: 5-7 hours on high / 7-8 on low
💡 Tips & Tricks
- ✔️ Use A Meat Thermometer: I know I've mentioned it before but, everyone needs one of these in their kitchen! The pork is cooked when it reaches an internal temperature of 63˚C / 145˚ F.
- ✔️ Use As Much Coke As You Need: Depending on the size of your joint, you may need more or less of the 2L stated in the recipe. If you run out of coke, top it up with water.
- ✔️ Score the fat:Use a sharp knife to score the fat diagonally in a criss-cross pattern. This allows the glaze to penetrate deeper and crisp up the fat.
- ✔️ Carving Tip: If you know you won't use all the gammon at once, consider carving some slices and leaving the rest whole. Sliced gammon tends to dry out faster than a whole joint.
