Ingredients

Scale

For the Lamb

  • 1 bone-in lamb shoulder (about 45 lbs / 22.5 kg)
  • 2 tablespoons olive oil
  • 6 garlic cloves, crushed
  • 2 tablespoons fresh rosemary leaves (or 1 tablespoon dried)
  • 1 tablespoon salt
  • 1 teaspoon black pepper
  • 1 lemon, halved
  • 1 cup water or low-sodium chicken stock

Optional Sauce or Vegetables

  • 1 tablespoon cornstarch (to thicken pan juices)
  • 1 cup mushrooms (optional)
  • 2 carrots, cut into chunks
  • 1 onion, quartered

Instructions

  1. Preheat and Prepare: Preheat oven to 450°F (230°C). Line a roasting pan with foil and place a rack on top. Pat the lamb shoulder dry with paper towels and score shallow cuts into the fat.
  2. Make the Garlic-Rosemary Rub: Combine olive oil, garlic, rosemary, salt, and pepper in a small bowl. Rub generously over the lamb, pressing into the cuts. Place lamb on the rack, squeeze lemon juice over it, and add lemon halves to the pan.
  3. Start with a Hot Blast: Roast uncovered for 20 minutes to brown and seal in juices.
  4. Slow Roast: Reduce oven temperature to 325°F (160°C). Add 1 cup water or stock to the pan and cover tightly with foil. Roast for 3 hours, basting occasionally.
  5. Crisp the Skin: Remove foil and roast uncovered for another 30–45 minutes until the surface is golden and crispy.
  6. Rest and Serve: Transfer to a platter and rest for 20 minutes before carving. Use pan juices to make gravy or drizzle over the lamb for extra flavor.

Notes

  • Pat the lamb completely dry before seasoning for the best crust.
  • Use fresh rosemary for the most aromatic flavor.
  • Slow roasting is key — it breaks down the collagen for a tender result.
  • Rest before carving to lock in moisture and juiciness.
  • Save the drippings for roasting vegetables or making gravy.
  • Storage: Refrigerate up to 3 days or freeze for 2 months.
