Ingredients

Instructions

  1. Step 1: Preheat oven to 325°F. Pat dry 4 lamb shanks (about 1.5 lbs total) and season with 1 1/2 tsp salt and 1 tsp black pepper. Heat 3 tbsp olive oil in a large oven-safe pot over medium-high heat.
  2. Step 2: Brown the lamb shanks on all sides for 6-8 minutes until deeply golden, then remove and set aside.
  3. Step 3: Lower heat to medium and add 1 large diced onion, 2 chopped carrots, 2 chopped celery stalks, and 4 minced garlic cloves. Sauté for 5-6 minutes until softened and fragrant.
  4. Step 4: Pour in 1 cup dry red wine to deglaze the pot, scraping up browned bits, and simmer for 3 minutes until reduced by half.
  5. Step 5: Add 2 cups beef broth, 3 fresh rosemary sprigs, and 1/4 cup chopped dried bush tomatoes, then return lamb shanks to the pot. Cover with a lid.
  6. Step 6: Transfer the pot to the oven and slow-cook for 2 1/2 to 3 hours until the lamb is very tender and falling off the bone.
  7. Step 7: Remove rosemary sprigs before serving. Serve lamb shanks with the rich sauce and vegetables spooned over mashed potatoes or roasted root vegetables.
