In central PA, pot pie is made with noodles not a crust. Pot pie noodles are small thin squares. Its more of a soup. Not your typical chicken pot pie.
I posted a picture of what a pot pie noodle looks like.
In a large stock pot add chicken. Cover with water. Add bouillon granules. The amount you add will depend on the amount of water you add. The water should look yellow. Cook until chicken is done. Remove chicken from pot. Save the stock you just made.
Remove chicken from the bone. Discard bones. Add chicken, pot pie noodles, potatoes, corn, and onion to stock. Simmer for 1 hour.
