Ingredients

Instructions

  1. Step 1: Preheat oven to 325°F. Heat 3 tbsp olive oil in a heavy ovenproof pot over medium-high heat. Brown 4 lamb shanks on all sides for about 8 minutes until deeply golden, then transfer to a plate.
  2. Step 2: Add 1 large diced onion, 2 sliced carrots, and 2 sliced celery stalks to the pot; sauté for 5-6 minutes until softened. Stir in 4 minced garlic cloves, 2 tbsp tomato paste, 2 tsp dried crushed lemon myrtle leaves, and 1 tsp crushed pepperberries; cook for 2 minutes until fragrant.
  3. Step 3: Pour in 1 cup red wine and scrape up browned bits, then add 3 cups beef broth, 1.5 tsp salt, and 1 tsp freshly ground black pepper. Return lamb shanks to the pot, cover, and braise in the oven for 2.5 to 3 hours until meat is tender and falling off the bone.
  4. Step 4: Meanwhile, boil 2 lbs peeled, quartered potatoes in salted water until tender, about 20 minutes. Drain and mash with 4 tbsp butter and 1/2 cup milk until smooth and creamy.
  5. Step 5: Serve the lamb shanks over mashed potatoes, spooning the rich lemon myrtle-infused braising sauce on top.
