Step 6: Slow Cook Until the Chicken Is Tender - Cover the slow cooker and cook on LOW for 5 to 6 hours or on HIGH for 3 to 4 hours. The chicken should be completely cooked through and tender. If you check with a
meat thermometer, the chicken should reach 165°F. I usually choose LOW when my schedule allows because I love being able to get dinner started and forget about it for most of the afternoon.
