Can I make this soup ahead of time?
Yes. Prepare the soup through step 10, then cool and refrigerate for up to 3 days. Add the noodle soup mix and simmer just before serving to keep noodles tender.
Why add a whole potato and then mash it?
The whole potato simmers with the vegetables and broth, then mashing it returns the starch to the liquid, naturally thickening the soup without cream or flour.
Can I use fresh chicken instead of rotisserie?
Yes, but poach or roast 2 whole chicken breasts separately, then shred. Add at step 9. Rotisserie chicken saves time and adds flavor from the seasoning.
What does the Parmesan rind do?
It infuses umami depth into the broth as it simmers. Remove before serving or let it soften and break into small pieces to stay in the soup.
How long does it simmer before adding noodles?
Simmer for 30-40 minutes until all vegetables are tender, then add the noodle soup mix at the very end so the noodles cook properly without getting mushy.
