Christmas Ham: Slow Cooker Recipe
Who has oven space during the Christmas period? Between the roast potatoes, stuffing, and endless baked treats, the oven is already doing overtime. That's where this slow cooker ham swoops in to save the day!
Not only is it the best way to free up that precious oven real estate, but it's also an easy recipe that's lighter on the wallet than a traditional silverside beef roast or whole turkey-perfect if you're on a tight budget this festive season.

While it's a natural fit for the time of the year when you're hosting and entertaining, don't let Christmas have all the fun. This real crowd pleaser is equally perfect for a Sunday Roast or any gathering with family and friends. Why wait for the holidays to enjoy a show-stopping ham?
Ingredients and Substitutes
- gammon joint: we typically cook unsmoked gammon joints. If you are using smoked gammon, you may want to remove some of the salt content by soaking the gammon in cold water for a few hours before cooking.
- vegetables: carrot and onion, both peeled and roughly chopped.
- spices: we used black peppercorns, a cinnamon stick, cloves and coriander seeds, but you can experiment with star anise, allspice berries and many other spices.
- apple cider: not overly sweet.
- apple juice.
- honey: or maple syrup, but honey works better with mustard.
- dark brown sugar: or light brown sugar.
- Dijon mustard: or wholegrain mustard, or English mustard.

Step-By-Step Method
1. Place the carrot, onion wedges, cinnamon stick, cloves, coriander seeds and black peppercorns on the bottom of the slow cooker.

2. Place the gammon joint on top. Pour the cider and apple juice over. Cover with the lid and cook on high for 4-5 hours, or on low setting for 6-8 hours.


3. When the gammon is finished cooking, preheat the oven to 220°C (200°C Fan). Line a small roasting tin with foil.
4. In a small bowl, mix the honey, dark brown sugar and mustard.
5. Take the cooked gammon out of the slow cooker and remove any string or netting. Cut the rind (if your joint has it) leaving a thin layer of fat on top. Score the fat in a criss-cross pattern (diamond pattern) using a sharp knife.
6. Smear the honey mustard glaze on top of the ham and roast in the oven for 30 minutes, until dark and sticky.



7. Brush some more glaze that gathered at the bottom of the tray on top of the gammon just before serving.

What To Serve Slow Cooker Gammon With?
Pairing your brown sugar gammon with the perfect side dishes takes your meal to the next level. For a hearty base, you can't go wrong with roast potatoes or baby hasselback potatoes-both are great options that soak up the sticky glaze beautifully.
Vegetable sides like honey roasted carrots and parsnips or roasted Brussels sprouts with balsamic reduction add vibrant flavours and balance to your roast dinner spread. If you're a sourdough baker, you must try it with Sourdough Cauliflower Cheese!
For an extra festive touch, a dollop of cranberry and grapefruit sauce brings just the right amount of tangy sweetness. A feast fit for any occasion!

Recipe FAQs
Using a meat thermometer is the best way to ensure your gammon is perfectly cooked. Insert it into the centre of the meat, avoiding the bone if your joint has one, and check for an internal temperature of 71°C (160°F). It's always a good idea to double-check before moving on to the glaze step.
Not completely! As long as there's enough liquid to cover about half of the gammon joint, the slow cooking process will ensure even cooking. The steam and heat inside the slow cooker work wonders without needing to submerge the meat entirely.
Yes, but it's rare if you stick to the suggested cooking time. Overcooking can make the meat dry, so aim for the lower end of the cooking range and test with a fork-if it flakes apart easily, it's done!
Absolutely! While apple juice is a classic choice, you can experiment with different things in your slow cooker. We tried it with regular Coca Cola, Diet Coke, Cherry Coke (try our Slow Cooker Gammon in Cola), pineapple juice and Dr Pepper. So don't be afraid to get creative next time!
