If you’re updating your go-to centrepiece, this baked ham with brown sugar and mustard glaze is the one to keep. It’s minimal effort, glossy, sweet-and-tangy, and gives you that “wow” look without needing a full-day kitchen marathon, plus it’s just as good cold the next day (hello, unbeatable sandwiches).
“This ham is amazing! I left the skin on because we love the crispiness of the rind and I also added crushed garlic to the sauce. My new favourite ham recipe. Looking forward to making sandwiches from it. Thank you Nikki”

Nicky’s Notes

I know those huge joints of ham with the bone in look impressive, but 5 kilos of ham can be a little too much – unless you’re having a big party or you’re happy to eat ham butties for the next 6 months.
This recipe uses a regular gammon joint (about 1.4kg/3 pounds) that you can buy from most supermarkets at a reasonable price (ours was £11). For us, that was enough for dinner, sandwiches for the next couple of days and an extra portion to put away for another meal (such as fried rice, or ham and cheddar croquettes).

Difference between gammon and ham
Gammon is basically ham before it has been cooked. Gammon (which is a cut of meat from the hind leg of a pig) is cured – usually in brine or using a dry salt method (similar to bacon). This curing process preserves the gammon and develops the pink texture. The gammon then needs to be cooked before being eaten. Once cooked, it will be ham. You can slice it and serve it as you would with ready-sliced ham from the deli counter.
This gammon/ham differentiation can be a little confusing as, in the UK at least, a popular pub dish is gammon and chips. No, we don’t serve up raw gammon with our chips. It’s simply a thick slice that has been taken off the gammon joint before being cooked. Then it’s fried or grilled. This is known a gammon steak (but I guess really it’s a ‘ham’ steak).
Smoked or un-smoked:
Personally I prefer smoked, as it has a greater depth of flavour, but go with what you prefer.

🧑🍳 Abbreviated Recipe
***Full recipe with detailed steps in the recipe card below***
Place the gammon joint in a large pan, cover with water and add the quartered onion, peppercorns and bay leaves, then bring to the boil and simmer for 20 minutes per pound (a 1.4kg/3lb joint takes about 1 hour).
Lift out and rest on a board for a few minutes, then carefully remove the skin with a sharp knife, leaving as much fat behind as you can.
Score the fat, then brush all over with a glaze of brown sugar, Dijon mustard, wholegrain mustard and spiced rum.
Bake at 190C/375F for 20 minutes, basting with more glaze halfway through cooking.

Best Ham Glaze
Personally I love a brown sugar and mustard glaze, but you could replace the sugar with honey if you prefer. You could also:
- Add orange zest
- Add minced ginger
- Give it an Asian twist by making a glaze from brown sugar, garlic, soy sauce, chilli sauce and ginger
- Give it an Italian twist by making a glaze from oregano, thyme, rosemary, lemon zest, garlic and olive oil
Delicious eaten hot, sliced into thick slabs as part of a main mean, or served cold, sliced thinly for sandwiches etc.

Slow Cooker method
You can do the boiling stage in a slow cooker if you prefer. Simply add the gammon to the slow cooker, cover with just-boiled water, the quartered onion, peppercorns and bay leaves. Then cook on High for 4-5 hours or Low for 6-7 hours. Then drain, glaze and bake in the oven as per the regular recipe.
How long will home cooked baked ham last?
Quickly cool, cover and refrigerate leftover ham. It should keep for 3 days.
You can also freeze chunks/cubes of ham. Defrost them in the refrigerator overnight, then add other recipes – cooking the meat until piping hot throughout. See some ideas for this below.

Leftover baked ham is great in :
