If there’s one thing I make every single Christmas, it’s my slow cooker gammon in ginger beer.

A naturally gluten free recipe, this is the easiest meat for a roast ever – simply chuck it in the slow cooker and forget about it.

As an additional step, you can also make a simple marmalade glaze for that extra step – making the perfect slow cooker gammon for Christmas.

So if you’re looking for simple Christmas dinner recipes which everyone will love, look no further.

I especially love making this slow cooker gammon for Boxing Day, or as a side to a Christmas turkey.

The leftovers are perfect for cold cuts over the ‘in between’ period, in sandwiches or chopped up and made into my gluten free chicken and ham pie.

How to do slow cooker gammon

I absolutely love slow cooker recipes – I cook them a lot in day-to-day life, and yet I hardly ever post any on here.

But honestly, cooking things in a slow cooker (I have a Crockpot like this one) makes life SO easy.

It’s really easy to cook gammon in a slow cooker, you just need to cover it with enough liquid so that it’s submerged and then cook!

You can either cook this gammon for 3 hours on high or six hours on low – depending how far ahead in the day you want to make it.

For example, if you wanted to eat this slow cooker gammon in the evening, you could just chuck it on low in the morning and leave it.

Slow cookers make meat really tender and juicy, so it means you’re pretty much guaranteed to have juicy, succulent joints every time.

I cook my slow cooker gammon in ginger beer but you can cook it in pretty much any liquid.

Slow cooker ham in cola works amazingly, as does slow cooking ham in apple juice or cider, or even alcoholic ginger beer like Crabbies.

My marmalade glaze for gammon

The pièce de résistance of this slow cooker gammon comes with the marmalade glaze.

Slow cooking the ham leaves it juicy and tender, but adding the glaze gives it a sweet and sticky finish.

The glaze is made from mixing together some of the cooking liquid with marmalade and brown sugar.

In the oven this then seeps into the meat, glazing the fat which goes crispy and delicious.

When the meat is done in the slow cooker, simply trim off any of the rind and then criss-cross the fat with a knife.

I like to baste the ham with the extra glaze half way through cooking as this helps to keep it moist in the oven and full of flavour.

How to serve my slow cooker gammon

This slow cooker gammon is so versatile, you can either have it as the star of the show or serve it up alongside beef or turkey.

It’s so easy because it’ll just cook away in the Crockpot while you prepare everything else.

I love this ham served up with my super crispy roast potatoes and an extra large helping of my gluten free cauliflower cheese.

This ham goes with pretty much any vegetable, and I like to drizzle over the extra glaze as a sauce when serving.

You could also dish these slices of gammon up with a gluten free gravy if you prefer.

I also love keeping leftovers of this slow cooker gammon to serve in a juicy ham sandwich, or as cold cuts with cheese and gluten free crackers.

And to be completely honest, I usually keep a tub in the fridge and just picks of it out when I’m feeling peckish!

My slow cooker gammon recipe

This slow cooker gammon recipe is the best recipe for Christmas dinner, Boxing Day – or just any day you want something delicious!

The marmalade takes it up a level but even without it, it’s just delicious, and so simple cooked in a slow cooker or Crockpot.

This recipe serves four people – if you make it with a larger joint make sure to increase the cooking time and check it’s thoroughly cooked through.

Slow Cooker Gammon in Ginger Beer

Prep Time: 5 minutes
Cook Time: 3 hours 15 minutes
Total Time: 3 hours 20 minutes

This gluten free slow cooker ham in ginger beer is the perfect Christmas Day or Boxing Day treat. Perfect eaten from the slow cooker or make my easy marmalade glaze for an extra special treat, finished off in the oven!


  • 1kg unsmoked gammon joint
  • 750ml ginger beer

For the glaze:

  • 2 tbsp marmalade
  • 60ml cooking liquid from the gammon
  • 1 tbsp dark brown sugar


  1. Unwrap any plastic from the gammon joint and place in the slow cooker. Pour over the ginger beer and top up with water if needed, so that the ham is just covered. Cook on high for 3 hours or low for 6 hours. The ham can be eaten at this stage, or read on if you want to glaze it.

If glazing the ham:

  1. When the ham is cooked, preheat the oven to 200'C / Fan 180'C / Gas Mark 6. Line a baking tin with foil and set to one side.
  2. Spoon out 60ml of the cooking liquid from the ham into a small saucepan. Add the marmalade and the dark brown sugar to the pan, stir and bring to the boil. Simmer for 3-4 minutes.
  3. Remove the ham from the slow cooker. If there is any rind, trim this off and then score the fat underneath. Place the ham in the foil lined tray - If the tray is too big, use bits of foil to prop the ham up so that the fat is on the top.
  4. Pour the glaze over the top of the ham, then place in the oven for 15 minutes. Half way through you can baste the ham with the glaze before finishing the cooking off.
  5. Remove from the oven and leave to sit for 10-15 minutes before slicing up and serving. I like to drizzle the extra glaze from the pan over the top of the slices before serving up for extra flavour.


This ham can be made ahead of time and frozen in slices - it will also keep in the fridge for 3-5 days after cooking.

This also works really well with an alcoholic ginger beer like Crabbies, or alternatively you can use Coca-Cola or cider.
