• Freshly grated Parmesan cheese or Parmesan crisps (see Note)
To prepare broth: Place the chicken, leek, 2 ribs celery, 3 carrots, 1 bunch chopped parsley, 6 branches thyme, bay leaf and peppercorns into a deep pot and cover with water by 1 inch. Set the pot over high heat and bring to a boil, then reduce the temperature and simmer the liquid until the chicken is very tender, about 75 to 90 minutes. Turn off the heat.
Remove the chicken to a carving board and allow it to cool. Set the pot with the broth over medium-low heat and simmer until the broth is reduced a little to enrich the flavor, about 15 minutes. Add 1 teaspoon salt, or to taste. Strain the broth through a sieve into another pot and discard the herbs and vegetables. Remove and discard the skin from the chicken and cut the meat from the bone and into chunks. (At this point you can store the broth and the chicken separately in the refrigerator or freezer.)
To prepare soup: Add the 4 carrots, 1 rib celery and 1 tablespoon thyme to the broth and set over medium heat. Simmer until vegetables are tender crisp, about 3 minutes. Add the diced chicken, noodles and 1/4 cup parsley and season to taste with salt and pepper. Garnish with Parmesan cheese or Parmesan crisps.
