    • Gluten Free
    • Preparation time: 20 minutes
    • Cooking time: 2 hours 10 minutes
    • Total time: 2 hours 30 minutes

    Serves: 8

    Ingredients

    1.5kg maris piper potatoes, cut into about 0.4cm-thick slices
    ½ celeriac, peeled and cut into about 0.4cm-thick slices
    1 large onion, sliced
    4 garlic cloves, crushed
    3 rosemary sprigs, leaves stripped
    6 juniper berries
    1 tbsp capers
    100g Lurpak Slightly Salted Butter, softened
    1 lemon, zest
    2-2.5kg leg of lamb, trimmed of excess sinew
    450g pack lamb gravy, heated

    Method

    1. Preheat the oven to 220°C, gas mark 7. Season and toss the potatoes, celeriac and onion over the base of a large roasting tin; pour over 100ml water. Use a pestle and mortar to crush the garlic, rosemary, juniper and capers to a rough paste; stir in the butter with the lemon zest and plenty of black pepper.

    2. Pierce the lamb all over with a sharp knife and rub with the butter mixture. Sit the lamb on top of the potatoes, season with sea salt and roast for 20 minutes. Reduce the heat to 180°C, gas mark 4, and cook for 1 hour 20 minutes, rotating the lamb halfway. Lift the lamb off the potatoes and rest on a board loosely covered with foil.

    3. Increase the heat to 200°C, gas mark 6. Tip the tin and baste the potatoes with any juices; return to the oven for 30 minutes while the lamb rests. Before serving, pour off and discard any excess fat from the potatoes. Serve with the sliced lamb, gravy and steamed greens, if liked. 

     

    Cook’s tip
    You can vary the aromatics in the butter crust. Try sage or thyme instead of rosemary, anchovies instead of capers or fennel seeds instead of juniper berries
