Ingredients

Instructions

  1. Step 1: Preheat oven to 325°F. Rub 1 tbsp lemon myrtle powder, 1 tsp salt, and 1/2 tsp black pepper evenly over 4 lamb shanks. Heat 3 tbsp olive oil in a large ovenproof pot over medium-high heat.
  2. Step 2: Sear the lamb shanks in the hot oil for 4-5 minutes per side until deeply browned. Remove and set aside.
  3. Step 3: In the same pot, add 5 smashed garlic cloves, 1 large quartered red onion, 3 chopped carrots, and 2 chopped parsnips. Sauté for 5 minutes until vegetables start to soften and become fragrant.
  4. Step 4: Stir in 2 tbsp tomato paste and cook for 2 minutes, then pour in 2 cups beef broth and add 2 sprigs fresh rosemary. Return lamb shanks to the pot, cover tightly, and transfer to the oven.
  5. Step 5: Slow-cook for 2.5 to 3 hours, basting occasionally, until lamb is tender and falling off the bone. Remove rosemary sprigs before serving with roasted vegetables and pan juices.
