We’re BIG fans of a Sunday roast dinner in our family. As soon as the colder weather starts drawing in we love nothing more than knowing we’ve got dinner simmering away in the slow cooker while heading out for a family walk. This slow cooker gammon joint, with a balsamic and orange glaze, is always a hit with my family.

This is a gammon joint that you can prepare in the morning, get it in the slow cooker and then you don’t have to do much until it’s ready for serving. This is such a simple way to enjoy a family dinner without being tied up in the kitchen all day.

I personally like to use a 750g gammon joint for this slow cooked gammon recipe. This is a great size for feeding a family, and having a little leftover for gammon, air fryer chips and eggs, a nice tasty omelette or even a pea and ham soup.

While you’re here be sure to check out my slow cooker tips which is packed full of ideas to help you get the most from your slow cooker. I’ve got a ton of easy slow cooker recipes too that are perfect if you want to make more easy family meals.

You can leave this to cool slightly, and slice into slices, or you can tear it apart for this slow cooked pulled gammon meat/slow cooker ham, which is similar to slow cooker pulled pork, that is perfect for roast dinners, sandwiches and will last for several meals easily. Perfect for cooking up in December when you have more visitors.

Slow cooker gammon joint with balsamic & orange glaze

Ingredients for slow cooker gammon joint:

1/3 cup of brown sugar (70g approx)

1/3 cup of balsamic vinegar (70ml approx)

1/3 cup of pure orange juice (70ml approx)

A gammon joint. I use 750g for this recipe, smoked usually, but you can use unsmoked also if you want to have it a little less salty.

You could use a pre-made glaze, such as this balsamic glaze.

Method for how to cook gammon joint with balsamic & orange glaze or glazed ham:

Combine the brown sugar, balsamic vinegar & pure orange juice together.

Mix well.

I like to whisk it and then add this to the slow cooker pot.

Place the gammon joint into the slow cooker. Make sure to remove the plastic from the outside first.

As I bought a smoked joint I boiled it for 5 minutes first on the hob, just to attempt to remove a little of the salt from my gammon joint. You can skip this step if you want to.

Move it around to cover it fully in the glaze.

Slow cook on high for 4 hours, or low for 8 hours. Times may vary based on your slow cooker but this is a rough guide.

Turn every 1 hour on high or even 2 hours on low if you can.

Remove the joint. Shred the meat.

Boil the leftover glaze in a saucepan, until it thickens up a little.

Spread this over the gammon or even just use it as a dipping sauce.

This is also great served with a brown sugar bbq sauce if you fancy something a little different!

Cooking a 750g gammon joint in a slow cooker:

As you’ve seen above I have used a 750g gammon joint in my slow cooker. You can cook this on high for 4 hours, or low for 8 hours. Check it is cooked completely before serving of course!

I tend to leave mine to rest in a roasting pan before I serve it, just so you can get some actual slices. If you don’t want to wait then just shred it up as it still tastes absolutely delicious!

What colour should gammon be when cooked?

You want the gammon to be a dark pink colour and have an internal cooking temperature of at least 71C (160F approx).

How much water do you need for this recipe?

None at all!

If you want to avoid the gammon sticking to the bottom of the slow cooker a little then you can use a splash of stock, but I don’t bother these days.

You could use stock and then save that for making a ham and pea soup.

Turn it regularly to avoid it sticking and that should be sufficient.

Cooking a slow cooker gammon recipe:

You can use stock, water, or just about any liquid that you like to cook your slow cooker gammon. Slow cooker gammon cola is quite popular, where you just cook a gammon joint in a can of diet coke.

I’ve cooked my gammon in apple juice, and multiple other things too over the years including cola, cider and even Dr Pepper. Adding a couple of bay leaves can be a nice addition to the pot too. A drizzle of honey and wholegrain mustard1 tbsp works great too.

How to cook a smoked gammon joint:

Personally I like to boil a smoked gammon joint for a little while before I put it in the slow cooker, as otherwise I find it to be too salty. This is a great way to help start the cooking time before transferring to the slow cooker.

Can you cook a slow cooker gammon joint from frozen?

I would firmly NOT recommend this in the slow cooker. It can take quite a while for meat to heat up in the slow cooker and you could get sick!

Defrost in the fridge for 24 hours before cooking in your slow cooker or buy a fresh joint where possible to avoid the wait time!

What is the safe internal temperature for a slow cooker gammon joint?

For me personally I always make sure that the gammon is at least 71C (160F) before serving. Often I cook this in advance and serve it as a cold platter meat, and so I want to be double sure that the temperature was safe before cooling and slicing up!

Can you make this gammon joint overnight in the slow cooker?

Yes, definitely! Check if your slow cooker needs preheating on high beforehand but then leave it on low overnight, for at least 8 hours.

You could stretch this to 10 – 12 hours with no issues.

What is the 750g gammon joint slow cooker time?

Slow cook for a minimum of 4 hours on the high setting or 8 hours on the low setting.

ALL of the slow cooker recipes on this website have been cooked using a Ninja Foodi OL750UK, or a previous Ninja multi-cooker model, but you can use ANY slow cooker, as timings should be very similar.

Can you overcook this gammon?

Slow cooker gammon is hard to overcook, thanks to the low temperature and gentle cooking.

Should you leave gammon to rest after cooking?

I like to leave this to rest for 15 minutes before I carve it. If you don’t mind it being more shredded then you can go ahead and carve it right away.

Letting it rest gives the joint time to relax before carving, which makes for even slices.

What to serve with a slow cooker gammon joint:

I have a ton of delicious recipes here. If you’re going for a classic roast dinner then try my sage and onion stuffing, beef gravy, air fryer frozen yorkshire puddings, air fryer roast potatoes or rosemary and garlic roast potatoes, air fryer carrots and parsnips or air fryer tenderstem broccoli.

What I love about making this in the slow cooker is that it leaves the oven free for cooking the rest of the roast dinner trimmings.

Air fryer mac and cheese or air fryer cauliflower cheese works very well with this. As does a nice batch of air fryer frozen french fries and a couple of fried eggs.

My slow cooker gammon joint, with the stunning balsamic and orange glaze, is a delicious meat that will work great as the basis of a stunning family meal. It has a great flavour that makes it perfect as a traditional Sunday roast but also it has a modern twist.

I love to use some of this gammon for sandwiches, for salads or even just for ham and eggs.

This dish is packed full of flavour, but it is also so simple to prepare. It takes just a few ingredients, my trusty slow cooker and then the gift of time to wait for an ordinary gammon joint to become a stunning gourmet creation.

The gammon joint is succulent, tender and has a lovely sweet yet tangy sauce. The orange gives a nice zesty punch of flavour and it is always a hit in my house.

I love how versatile this gammon is. Ideal for a platter when you’re hosting guests and a great cold meat for Christmas time too. A Christmas ham is a great way to bulk out plates when you’ve got lots of people to feed.

Good food doesn’t need to be complicated, as this recipe shows. It’s full of flavour, has a luscious glaze and is super simple to prepare too.

What a lovely and easy recipe! I had a 1.2kg unsmoked gammon so doubled the quantities of sugar, balsamic and orange juice. Also added a bit of extra time to the cooking. Ended up with quite a bit of liquid, but it boiled down nicely to pour over shredded ham. Will definatey do this recipe again.
