Start by prepping your ingredients. Peel and chop the carrots, potatoes, onion, and celery. Coarsely chop the tomatoes or cherry tomatoes. Set them aside for easy access.
In your Crock-Pot, layer the chopped vegetables at the bottom. Begin with the carrots, followed by the potatoes, tomatoes, onion, and celery.
Place the boneless and skinless chicken thighs (or breast filets) on top of the vegetables. This method allows the chicken to soak up all the delicious flavors as it cooks.
Sprinkle the torn bay leaves, salt, and pepper over the chicken. Pour the fat-free chicken broth into the pot, ensuring that all the ingredients are submerged.
Cover your Crock-Pot with the lid and set it to cook on low for 6-8 hours or high for 4 hours. The longer it cooks, the more tender the chicken will become.
About 30 minutes before serving, mix the cornstarch with a little water to create a slurry. Stir this mixture into the stew to thicken the broth, and allow it to cook for the remaining time.
Once the cooking time is up, remove the bay leaves and shred the chicken if desired. Ladle the stew into bowls and enjoy the hearty goodness!
