Ingredients Equipment Method Notes

Ingredients
  

  • 1.5 kg lamb shoulder or leg preferably with a good fat cap
  • 4 cloves garlic crushed or chopped
  • 2 tbsp fresh rosemary chopped
  • 1 tsp lemon zest about half a lemon
  • 3 tbsp olive oil
  • to taste sea salt coarse
  • to taste black pepper freshly cracked
  • 1/4 cup red wine or broth for roasting pan

Equipment

  • Roasting pan
  • Meat thermometer
  • Kitchen twine
  • Sharp chef’s knife
  • Basting brush
  • Aluminum foil

Method
 

  1. Preheat your oven to 180°C (350°F). Take the lamb out of the fridge and let it sit at room temperature for about 30 minutes to ensure even cooking.
  2. Combine crushed garlic, chopped rosemary, lemon zest, salt, pepper, and olive oil to create a fragrant herb paste. Rub this mixture all over the lamb, pressing it into any crevices for maximum flavor.
  3. Tie the lamb with kitchen twine at 1-inch intervals to promote even cooking and a neat presentation. Place it in a roasting pan, fat side up, and pour a splash of red wine or broth into the pan to keep the meat moist.
  4. Insert a meat thermometer into the thickest part of the lamb. Roast in the oven, cooking for about 20 minutes per 500g, until the internal temperature reaches 60-63°C (140-145°F) for medium-rare. Baste with pan juices occasionally to develop a flavorful crust.
  5. Once the lamb reaches the desired temperature and has a deep, golden-brown crust, remove it from the oven. Cover loosely with aluminum foil and let it rest for at least 15 minutes to allow the juices to redistribute, resulting in tender, juicy slices.
  6. Uncover the lamb and carefully carve against the grain with a sharp knife. Serve slices topped with pan juices or a simple gravy, accompanied by roasted vegetables or winter greens for a hearty holiday meal.

Notes

For an even more flavorful crust, you can increase the oven temperature to 220°C (430°F) for the last 10 minutes of roasting, watching carefully to prevent burning.
