Add chicken to a slow cooker and season with pepper, onion powder, garlic powder, and parsley flakes.
Add onion, celery, carrots, cream of chicken soup, cream of celery soup, and chicken broth.
Cook on high for 4 hours or low for 6 hours. Once chicken is cooked shred or cube it up and add it back to the crockpot. Add the package of gnocchi.
Turn the crockpot to high and let cook for about 30 minutes. I like to taste it once it's cooked and add a little bit of seasoning salt if needed at the end. Once gnocchi is tender serve!
