Ingredients

  • 1.8 kg (4 lb) leg of Welsh lamb, bone-in
  • 4 garlic cloves, slivered
  • 3 tbsp fresh rosemary, chopped
  • 3 tbsp olive oil
  • 6 leeks, halved lengthways
  • 200 g (7 oz) laverbread
  • 2 tbsp butter
  • 1 tbsp lemon juice
  • 250 ml (1 cup) lamb or vegetable stock
  • Salt and pepper, to taste

Method

  1. Preheat the oven to 220°C (425°F).
  2. Make small incisions all over the lamb and insert the garlic slivers.
  3. Rub the lamb with olive oil, rosemary, salt and pepper, and place in a roasting tray.
  4. Roast for 20 minutes at the high temperature, then reduce the oven to 180°C (350°F) and continue roasting for a further 1 hour to 1 hour 15 minutes, until a meat thermometer reads about 60°C (140°F) for medium, adjusting to preference.
  5. Add the halved leeks to the roasting tray for the final 30 minutes of cooking, turning once, until tender and lightly caramelised.
  6. Meanwhile, make the laverbread sauce: melt the butter in a small saucepan, stir in the laverbread, lemon juice and stock, and simmer gently for 8-10 minutes until warmed through and slightly thickened.
  7. Rest the lamb for 15-20 minutes before carving.
  8. Serve the sliced lamb with the roasted leeks and warm laverbread sauce spooned over.

Introduction: This celebratory roast brings together three of Wales's most iconic ingredients — lamb, leeks and laverbread — into a single centerpiece dish, traditionally prepared for St.

Cultural Background: This celebratory roast brings together three of Wales's most iconic ingredients — lamb, leeks and laverbread — into a single centerpiece dish, traditionally prepared for St. David's Day (March 1st) celebrations and other significant Welsh family gatherings.

Tips: Resting the lamb properly after roasting is essential for a tender, juicy result — don't skip this step. Use a meat thermometer for the most reliable doneness check. The laverbread sauce should be gently warmed, not boiled hard, to preserve its delicate flavour.

Variations: Add roasted root vegetables to the tray for a fuller festive spread. Serve with a red wine and rosemary gravy alongside the laverbread sauce. Add a Welsh cheese course to follow, in keeping with St. David's Day tradition. Not applicable in its traditional form; the dish is centred on a whole leg of lamb.

Storage: Refrigerate leftover lamb and leeks in an airtight container for up to 3 days; the sauce is best made fresh.

Reheating: Reheat lamb slices gently, covered, in a low oven at 150°C (300°F) to avoid drying out; make a fresh batch of sauce if needed.
