Instructions

1. Step 1: Heat 1 tbsp olive oil in a large Dutch oven over medium-high heat. Season 1.5 lbs lamb shoulder cubes with salt and pepper, then sear in batches until browned on all sides, about 4-5 minutes per batch; transfer to a plate.
2. Step 2: Add remaining 1 tbsp olive oil to the pot. Sauté 1 large chopped onion until softened, about 3 minutes, then add 3 minced garlic cloves and cook for 1 minute until fragrant.
3. Step 3: Return browned lamb to the pot, then add 4 medium carrots (peeled and cut into 1-inch chunks), 3 medium parsnips (peeled and cut into 1-inch chunks), and 2 medium potatoes (peeled and cut into 1-inch chunks). Pour in 4 cups beef broth and 1 cup red wine, then add 2 sprigs thyme, 1 bay leaf, and 1 tsp dried rosemary. Bring to a simmer.
4. Step 4: Cover the pot, reduce heat to low, and simmer for 2.5 hours until lamb is tender.
5. Step 5: Remove bay leaf and thyme sprigs. If stew is too thin, mix 2 tbsp all-purpose flour with 2 tbsp cold water to form a slurry, then stir into stew and cook for 5 minutes until thickened.
