Get broth together into large pot
Chop onion, carrots, and celery. Sauté them in butter and with the mushrooms until they begin to get soft.
Shred cooked chicken into the veggies. If chicken is not cooked, it can be cooked separately and then added. Allow flavors to mix for a few minutes.
Add the veggies/chicken to the broth. Add salt and pepper to taste and the other herbs. Allow this to cook covered on medium for about 30 minutes.
Make pasta separately, strain but KEEP the water. Add pasta to the broth and veggies/chicken. Allow this to cook covered for about 30 minutes. If the after 30 minutes the water has cooked down more than liked (the pasta is sticking out of the soup), then pour some of the pasta water into the pot. Stir, taste the broth, and salt and pepper more if needed.
The soup is ready at this point but can cook longer if needed. Take off stove and let sit for a few minutes. Serve and enjoy.
“Pinch broth” (when you don’t have stock): We often make and can our own broth, but sometimes I’m out and don’t want to run to the store. This quick substitute works surprisingly well, and you can see the picture below of an example.
Adding Pasta Water to the Soup: I usually end up adding another quart and then season it a bit... this is optional it really depends on your preference of broth to chunks.
