Ingredients

Instructions

  1. Step 1: Pat 2 lbs chicken thighs dry with paper towels and season with 1 tsp sea salt and 1/2 tsp black pepper. Cut 4 medium carrots and 2 medium parsnips into 1-inch chunks, and thinly slice 1 large onion.
  2. Step 2: Place carrots, parsnips, and onion in the slow cooker. Toss with 2 tbsp olive oil, 3 minced garlic cloves, 3 sprigs rosemary, and 2 sprigs thyme.
  3. Step 3: Arrange chicken thighs on top of vegetables, pressing gently to adhere herbs. Secure slow cooker lid and cook on low for 6 hours until chicken reaches 165°F internally and vegetables are fork-tender.
  4. Step 4: Carefully remove chicken and vegetables to a platter. Discard herb stems from sauce in the slow cooker, then transfer the liquid to a small saucepan.
  5. Step 5: Simmer sauce over medium heat for 5 minutes until slightly thickened, then spoon over chicken and vegetables before serving.
