Instructions

  1. Step 1: Toss 2 lbs cubed boneless lamb shoulder with 1/4 cup all-purpose flour, 1 1/2 tsp salt, and 1 tsp black pepper to coat evenly.
  2. Step 2: Heat 2 tbsp olive oil in a large skillet over medium-high heat. Brown the lamb cubes in batches for 3-4 minutes per side until nicely seared. Transfer browned lamb to slow cooker.
  3. Step 3: In the same skillet, sauté 1 large diced yellow onion and 3 minced garlic cloves for 3 minutes until softened and fragrant. Add 2 tbsp tomato paste and cook for 1 minute, then pour in 1 cup red wine, scraping browned bits from the pan.
  4. Step 4: Pour the onion and wine mixture into the slow cooker with lamb. Add 4 cups beef broth, 3 cups chopped carrots, 2 cups chopped parsnips, and 2 tbsp chopped fresh rosemary.
  5. Step 5: Cover and cook on low for 8 hours or high for 4 hours until lamb is tender and vegetables are cooked through. Stir gently before serving.
