Recipe by Print

This Slow Cooker Gammon in Cola recipe is another that should be on your "must try in the Slow Cooker" list. Don't be alarmed by the supposed wackiness, Gammon cooked in Cola really works!

Serves 8
Difficulty Easy
Prep Time 30 minutes
Cooking Time about 8 hours on low


  • 2kg unsmoked gammon joint
  • 2 litres full-fat Coke
  • 1 onion, sliced
  • 1 carrot, roughly chopped
  • 1 stick celery, chopped
  • 1 bay leaf
  • Good crack of pepper
  • Cloves (optional)
  • 150ml honey
  • 2 tbsp English mustard (wholegrain will work well too)
  • Salt and pepper to season


  1. Put the onion, carrots and celery into the slow cooker, and rest the gammon on top. Pour in the cola, and drop in the bay leaf and add a good crack of pepper to the cola. Ensure that the cola totally submerges the gammon. Cook on low for 8 hours.
  2. Now the gammon is cooked it's officially known as "ham" (although Americans call gammon "ham" even when uncooked!). Use two forks to lift the ham from the slow cooker to a roasting dish then heat your oven to 170°C; this is the perfect time to let the ham cool slightly so that you're able to work with it. You can discard the remaining contents of the slow cooker.
  3. Remove the layer of skin, then using your favourite sharp knife score a lattice into the thin layer of fat left on the ham. If you're feeling fancy, stab a clove into each of the diamonds in your lattice.
  4. Mix together the honey and mustard in a bowl with a crack of salt and pepper, then pour over the ham. Roast the ham for 20 minutes, basting half way through. Turn up the head towards the end if you think it needs it - you want the outside of the ham to be a gorgeous golden charred colour!

    I want to bring this to Christmas dinner. Can it be reheated and if so, how best to do so?

    Should the coke be heated before putting in the slowcooker?

    I made this recipe and the whole family loved it. I didn't bother with all the fancy stuff just simply coke and pepper. Then glazed with honey and mustard. Was a big hit in my house and just fell apart. ;) converted a few people to the idea of cola ham!!!

    Apologies for my ignorance. What is a 'crack' of salt and pepper? Thanks Mike

    Nice recipe. The novices (me, for instance) might like to know the temperature for roasting. Kind regards.
