Ingredients

Instructions

  1. Step 1: Place 3 lbs bone-in, skin-on chicken thighs in the slow cooker, then add 2 medium carrots (peeled and sliced into 1/2-inch coins), 2 medium parsnips (peeled and sliced into 1/2-inch coins), and 1 large onion (cut into 1/2-inch chunks).
  2. Step 2: Add 3 garlic cloves (minced) and pour over 1/4 cup fresh lemon juice, 2 tbsp dried thyme, 1 tbsp dried rosemary, 1/2 cup chicken broth, 2 tbsp olive oil, and salt and black pepper to taste.
  3. Step 3: Stir gently to coat all ingredients, then cover and cook on low for 6 hours until the chicken is tender and easily flakes with a fork.
  4. Step 4: Remove the chicken thighs and set aside. Skim any excess fat from the cooking liquid, then strain the vegetables and sauce through a fine-mesh sieve to separate the solids; reserve the liquid.
  5. Step 5: Return the chicken to the slow cooker with the vegetables and 1/2 cup of the reserved liquid, and let it rest for 10 minutes before serving.
