Prep time: 15 mins | Cook time: 5 hrs 15 mins | Total time: 5 hours 30 minutes | Servings: 8

| Calories: 896kcals


  • 2 kg bone-in leg of lamb
  • 1 tablespoon kosher salt
  • 2 teaspoon black pepper
  • 2 tablespoons olive oil
  • 12 cloves of garlic
  • 1 onion, quartered
  • 2 large carrots, sliced into rounds
  • 2 rosemary sprigs
  • 3 cups beef stock, low sodium
  • 2 cups water

For the gravy

  • 4 tbsp cornstarch
  • 1 cup water
  • 1 teaspoon salt
  • 1/2 teaspoon pepper


  1. Preheat the oven to 335 ℉. Add the onion, garlic, and rosemary to a metal roasting pan. Place the lamb in the roasting pan with the meaty part right side up.
  2. Sprinkle the lamb with a generous coating of salt and pepper and massage it into the lamb. Flip the lamb and arrange it so that the meaty part of the leg sits on a bed of onions and garlic. Apply more salt and pepper and massage it into the meat. Pour the oil over the lamb and rub it in.
  3. Pour the beef stock and water around the lamb. The liquid will not cover the lamb. Cover the roasting pan with foil to allow some of the broth to steam out.
  4. Place the lamb into the oven and roast for 4 1/2 hours. Remove the meat from the oven and use a fork to test the tenderness of the meat. If the meat easily falls apart the meat is ready. If it is not easily released when pricked with a fork the roasted leg of lamb needs a few more minutes. Place the lamb back into the oven uncovered for 45 minutes until it develops a rich brown colour.
  5. Remove the lamb and generously baste it with the pan drippings. Place the lamb onto a serving dish and tint the platter with foil to keep it warm while making the gravy.
  6. To make the gravy, skim off the layer of fat floating on the surface of the broth. Add 1/2 cup of water to the drippings. Place the roasting pan on the stove over medium-high heat.
  7. Place the cornstarch into a small bowl and whisk in the remaining 1/2 cup of water. Pour the slurry into the liquid stirring constantly. Let the gravy cook for 4-5 minutes until the gravy thickens up. Strain the gravy and pour it into a gravy boat.
  8. Serve the gravy alongside the lamb and your favorite side.
