Instructions

  1. Step 1: Preheat oven to 325°F. Rub 3 lbs bone-in lamb shoulder all over with 2 tbsp ground wattleseed, 4 minced garlic cloves, 2 tbsp chopped fresh rosemary, 2 tsp salt, and 1 tsp black pepper.
  2. Step 2: Heat 2 tbsp olive oil in a large oven-safe pot over medium-high heat. Sear the lamb shoulder on all sides until deeply browned, about 4 minutes per side.
  3. Step 3: Remove lamb and add 1 1/2 cups beef broth to deglaze the pot, scraping up browned bits, then return lamb to the pot. Cover with a lid and place in the oven to slow cook for 3 hours until tender.
  4. Step 4: While lamb cooks, toss 4 chopped carrots, 3 parsnips, and 1 quartered red onion with 1 tbsp olive oil and a pinch of salt and pepper. Spread on a baking sheet and roast in the oven for the last 45 minutes of lamb cooking until caramelized and tender.
  5. Step 5: Remove lamb and vegetables from oven. Let lamb rest for 10 minutes before slicing and serving alongside the roasted root vegetables.
