Ingredients

Instructions

  1. Step 1: Preheat oven to 325°F. Season 4 lamb shanks evenly with 1 tbsp salt and 1 tsp black pepper, then dredge each in 1/4 cup flour, shaking off excess.
  2. Step 2: Heat 2 tbsp olive oil in a large heavy ovenproof pot over medium-high heat. Add lamb shanks and brown on all sides for 8-10 minutes until a deep golden crust forms, then remove and set aside.
  3. Step 3: Reduce heat to medium, add 2 tbsp butter, then sauté 1 large diced onion, 4 minced garlic cloves, 3 chopped carrots, and 2 chopped parsnips for 6-7 minutes until softened and fragrant.
  4. Step 4: Stir in 2 tbsp tomato paste and cook for 2 minutes to deepen flavor.
  5. Step 5: Pour in 1 cup red wine to deglaze the pot, scraping up browned bits, and simmer for 3 minutes until wine reduces slightly.
  6. Step 6: Return lamb shanks to the pot; add 3 cups beef broth and 3 fresh rosemary sprigs. Bring to a simmer.
  7. Step 7: Cover pot with a lid and transfer to the oven, braising for 2.5 to 3 hours until lamb is fork-tender and falling off the bone.
  8. Step 8: Remove lamb and vegetables to a serving dish; skim fat from the cooking liquid and reduce sauce on stovetop over medium heat for 10 minutes until slightly thickened.
  9. Step 9: Serve lamb shanks topped with the rich sauce and braised root vegetables.
