Ingredients

Instructions

  1. Step 1: Preheat oven to 300°F. Heat 2 tablespoons olive oil in a large ovenproof pot over medium-high heat. Season 3 pounds bone-in lamb shoulder with 1 1/2 teaspoons salt and 1 teaspoon black pepper, then sear lamb in the hot oil for 4-5 minutes per side until deeply browned.
  2. Step 2: Remove lamb and set aside. In the same pot, add 1 large diced onion and 4 minced garlic cloves, sauté over medium heat for 5 minutes until softened and fragrant.
  3. Step 3: Stir in 14 ounces canned diced tomatoes, 2 tablespoons chopped dried bush tomatoes, 1 teaspoon ground pepperberry, 1 cup beef broth, and 2 sprigs fresh rosemary.
  4. Step 4: Return lamb shoulder to the pot, cover with a tight-fitting lid, and place in the preheated oven. Slow cook for 3 to 3 1/2 hours until lamb is fork-tender and sauce has thickened.
  5. Step 5: Remove rosemary sprigs before serving. Spoon bush tomato and pepperberry sauce over the lamb and serve with roasted vegetables or mashed potatoes.
