Instructions

  1. Step 1: Heat 2 tbsp olive oil in a large skillet over medium-high heat. Add 2 lbs lamb shoulder cubes and brown on all sides, about 5-7 minutes, then transfer the lamb to the slow cooker.
  2. Step 2: In the same skillet, add 1 large diced yellow onion, 4 cloves minced garlic, 3 medium chopped carrots, and 2 medium chopped parsnips. Sauté for 4-5 minutes until fragrant and starting to soften.
  3. Step 3: Transfer the vegetables to the slow cooker along with 2 tbsp harissa paste, 3 cups beef broth, 1 tsp ground cumin, 1 tsp ground coriander, 1 1/2 tsp salt, and 1/2 tsp black pepper. Stir gently to combine.
  4. Step 4: Cover and cook on low for 7-8 hours or on high for 4-5 hours until the lamb is fork-tender and the vegetables are soft.
  5. Step 5: Before serving, stir in 1/4 cup chopped fresh parsley for a bright herbal finish.
