Delia Smith Roast Glazed Gammon Ham is a classic centrepiece that delivers tender, juicy slices wrapped in a glossy, sticky glaze. The meat stays succulent inside while the outer layer turns beautifully caramelised and lightly crisp. It is a straightforward recipe that rewards patience more than skill, making it ideal for confident beginners. Allow around 2 hours 30 minutes to 3 hours in total, depending on the size of your gammon.
Ingredients
For the Gammon
- 1.8 to 2.2kg unsmoked gammon joint
- 1 onion, halved
- 1 carrot, roughly chopped
- 1 bay leaf
- 6 black peppercorns
For the Glaze
- 2 tbsp Dijon or English mustard
- 2 tbsp soft dark brown sugar
- 1 tbsp clear honey
- 1 tbsp orange juice or pineapple juice

How to Make Delia Smith Roast Glazed Gammon Ham
- Prepare the oven: Preheat the oven to 200°C or 180°C fan. Place a shelf in the centre of the oven so the gammon cooks evenly and the glaze caramelises without burning.
- Simmer the gammon: Place the gammon joint in a large saucepan and cover with cold water. Add the onion, carrot, bay leaf and peppercorns. Bring to the boil, then reduce to a gentle simmer. Cook for 20 minutes per 500g, plus an extra 20 minutes. Skim off any foam that rises to the surface.
- Prepare for roasting: Remove the gammon from the pan and place it on a board. Allow it to cool slightly. Carefully cut away the skin, leaving a thin layer of fat. Score the fat in a diamond pattern, taking care not to cut into the meat.
- Mix the glaze: In a small bowl, combine the mustard, brown sugar, honey and orange juice. Stir until smooth and spreadable.
- Glaze and roast: Place the gammon in a roasting tin lined with foil. Spoon and brush the glaze evenly over the scored fat. Roast in the preheated oven for 20 to 30 minutes, basting once halfway through, until the top is deep golden and sticky.
- Rest and carve: Remove from the oven and let the gammon rest for 15 to 20 minutes before carving. This keeps the slices moist and easier to cut.
Tips for the Best Roast Glazed Gammon
How do I stop the glaze from burning?
If the top begins to darken too quickly, loosely cover the gammon with foil for the remaining cooking time. Keep an eye on it during the final 10 minutes.
Should I soak the gammon first?
If your gammon is heavily salted, soak it in cold water for a few hours or overnight, changing the water once. Many modern joints are mild enough to cook without soaking.
How do I know when the gammon is cooked?
The meat should feel firm and the internal temperature should reach 70°C. After roasting, the glaze should look glossy and caramelised.
Can I add cloves?
Yes, you can press whole cloves into the scored fat before glazing for a traditional finish and gentle spice.
Serving Suggestions
- Serve warm with roast potatoes and seasonal vegetables.

FAQs
Do I need to boil gammon before roasting?
Yes, simmering first keeps the meat tender and removes excess salt before glazing and roasting.
Can I cook gammon without glaze?
You can roast it plain, but the glaze adds flavour and helps create a caramelised finish.
What is the difference between ham and gammon?
Gammon is sold raw and must be cooked. Ham is cured and cooked, ready to eat.
Can I prepare this in advance?
Yes, cook and glaze the gammon a day ahead, then cool and refrigerate. Reheat gently or serve cold.
