Recipe Notes
  • When I am ready to serve the soup, try putting a little parsley on top along with vegan sour cream from Daiya products which I love.
  • Before you pour the broth into the mushroom mixture taste for seasoning. It’s best to add season at this time.
  • The broth should have a light coat on the spoon for thickness.
  • I prefer a creamy broth. If it's not thick enough sprinkle cornstarch to thicken.
  • Replace the 1 cup of water with heavy cream, if you would like a heavier creamy soup.
