Add the chopped onion, celery, carrots, potatoes, bay leaves, fresh thyme and fresh rosemary to the slow cooker.
Place the chicken breasts on top of the vegetables. Season generously with salt and pepper, add the minced garlic.
Pour the chicken broth over the chicken and vegetables, ensuring everything is well submerged.
Cover and cook on low for 7-8 hours or high for 3-4 hours.
About 30 minutes before the cooking time is up, remove the chicken from the slow cooker. Allow it to cool slightly, then chop into bite-sized pieces.
Discard the bay leaves, thyme sprigs, and rosemary sprig from the slow cooker.
Return the chopped chicken to the slow cooker.
In a small bowl, mix together the cornstarch and water to create a slurry. Stir this into the slow cooker.
Continue cooking the stew on high for another 30 minutes, or until the stew has thickened to your liking.
Ladle the stew into bowls, garnish with fresh parsley, and serve warm. Enjoy!
