Ingredients

Instructions

  1. Step 1: Preheat oven to 325°F. Pat dry 4 lamb shanks and season with salt and black pepper. Heat 3 tbsp olive oil in a large ovenproof pot over medium-high heat and brown lamb shanks on all sides, about 4 minutes per side, then remove and set aside.
  2. Step 2: In the same pot, add 1 large sliced yellow onion, 3 diced carrots, and 2 diced celery stalks. Sauté over medium heat for 6 minutes until softened. Add 4 minced garlic cloves and 2 tbsp tomato paste, cooking for 2 minutes until fragrant.
  3. Step 3: Pour in 1 cup red wine to deglaze the pot, scraping up any browned bits from the bottom. Let the wine reduce by half, about 5 minutes.
  4. Step 4: Return lamb shanks to the pot and add 3 cups beef stock, 2 tsp ground dried wattleseed, and 3 fresh thyme sprigs. Bring to a simmer, cover with a lid, and transfer to the oven. Braise for 2.5 to 3 hours until lamb is tender and falling off the bone.
  5. Step 5: While lamb cooks, boil 2 lbs peeled and quartered potatoes in salted water until tender, about 20 minutes. Drain and mash with 4 tbsp butter and 1/2 cup milk until creamy. Season with salt and pepper.
  6. Step 6: Remove lamb and vegetables from the pot. Strain the cooking liquid into a saucepan and simmer over medium heat until sauce thickens and coats the back of a spoon, about 10 minutes. Adjust seasoning.
  7. Step 7: Serve lamb shanks over mashed potatoes with wattleseed gravy spooned generously on top.
