  1. Step 1: Pat the 2 lbs chicken thighs dry with paper towels, then season evenly with 1 tsp sea salt and 1/2 tsp black pepper.

  4. Step 4: Cook on low for 6 hours or on high for 3 hours until the chicken is cooked through and vegetables are tender.
  5. Step 5: Remove the chicken thighs and let rest for 5 minutes. Serve with the vegetables and sauce from the slow cooker.
