In a large sauce pan or stock pot, combine chicken stock, chicken, carrots and seasoning. Bring to a boil, cover, reduce heat and simmer for 20-30 minutes, until chicken is fully cooked. Remove chicken with a slotted spoon and set aside to cool.
Add cut noodles to pot. Return to a boil and let boil until noodles are desired tenderness, about 7-10 minutes, depending on the thickness of the noodles. The broth will thicken as the noodles cook until it is a gravy consistency.
Shred or dice cooled chicken and return to pot. Stir to combine and continue cooking until heated through. Serve immediately, or refrigerate and warm on the stove before serving.
