Add chicken, carrots, onion, celery, garlic, Italian seasoning and chicken stock to the slow cooker. Cover and cook on high for 4 hours or low for 6 hours.
About 30 minutes before you're ready to serve, remove chicken breasts and shred. Return chicken to pot and stir in gnocchi and heavy cream. Allow to cook another 20 - 30 minutes.
Immediately before serving, stir in spinach and parmesan cheese. Alternately, you can add the spinach and cheese to individual bowls and ladle the soup over top. Add salt and pepper to taste.
