Instructions

  1. Step 1: Preheat oven to 325°F. Heat 3 tbsp olive oil in a large heavy ovenproof pot over medium-high heat. Season 4 lamb shanks with 1 1/2 tsp salt and 1 tsp black pepper, then sear each for 4-5 minutes until browned on all sides. Remove and set aside.
  2. Step 2: Add 1 large diced yellow onion, 2 sliced carrots, 2 sliced celery stalks, and 4 minced garlic cloves to the pot. Sauté for 6-7 minutes until softened and fragrant.
  3. Step 3: Stir in 2 tbsp tomato paste and cook for 1 minute, then add 1/4 cup lemon aspen juice and 3 cups beef broth, scraping the browned bits from the bottom.
  4. Step 4: Return the lamb shanks to the pot along with 3 sprigs fresh rosemary. Cover and transfer to the oven to braise for 2 1/2 to 3 hours until the meat is tender and falling off the bone.
  5. Step 5: Remove lamb shanks and keep warm. Simmer the sauce on the stovetop for 10 minutes to reduce and thicken before serving over the lamb.
