Place chicken thighs in crockpot. You can fill up the bottom, but do not stack the thighs on top of one another. Cook in the slow cooker for 6-8 hours on low or 3-4 hours on high. Once they are done cooking in the crockpot take out each piece of chicken and shake off any excess liquid. Place the chicken on a rimmed baking sheet lined with foil. Make sure that you don't have a lot of the liquid left on the chicken. Broil the chicken on high for 5 to 10 minutes turning halfway to get each side crispy. Take out of the oven and enjoy!
