Place the chicken breasts in the bottom of the crockpot.
Add the chicken broth, chopped carrots, celery, and onion over the chicken.
Sprinkle in the garlic powder, dried thyme, salt, and black pepper. Stir gently to combine.
Add the cream of chicken soup on top but do not stir it in.
Cover and cook on low for 6-8 hours or on high for 3-4 hours, until the chicken is cooked through and tender.
About 30 minutes before serving, remove the chicken and shred it with two forks. Return the shredded chicken to the crockpot.
Open the biscuit dough and cut each biscuit into quarters. Stir them into the crockpot, making sure they are coated with the broth.
Cover and cook for an additional 30 minutes on high until the dumplings are cooked through.
Serve hot, garnished with fresh parsley if desired.
For extra flavor, you can sauté the onions, carrots, and celery in a pan for a few minutes before adding them to the crockpot.
You can also substitute the chicken with turkey or add in your favorite vegetables.
Feel free to adjust the thickness of the broth; if you prefer it thicker, you can add a cornstarch slurry in the last hour of cooking.
