Instructions

  1. Step 1: Preheat oven to 325°F. Rub 2 lbs bone-in lamb shoulder with 3 tbsp olive oil, 1 tsp salt, and 1/2 tsp black pepper.
  2. Step 2: Heat a large Dutch oven over medium-high heat. Brown the lamb on all sides for 5-6 minutes until deep golden. Remove and set aside.
  3. Step 3: Add 1 diced medium onion and 5 minced garlic cloves to the pot, sauté for 4-5 minutes until softened and fragrant.
  4. Step 4: Stir in 14 oz canned crushed tomatoes, 1 tsp dried oregano, 1 tsp dried thyme, and 1 tbsp chopped fresh rosemary. Pour in 1 cup red wine and bring to a simmer.
  5. Step 5: Return the lamb to the pot, cover with a lid, and place in the oven. Cook for 3 hours until lamb is fork-tender and sauce has thickened.
  6. Step 6: Remove lamb and let rest for 10 minutes before slicing. Serve with the tomato-herb ragout spooned over the top.
