Recipe Notes
- Soup can cook for as long as 12 hours on low.
- Can use 8 cups vegetable stock in place of Chicken and Beef broth.
- I like to cook the onions during the day, then add the broth and cook through the night.
- Soup can be cooled and refrigerated for 3-4 days. Reheat when ready to serve.
- This recipe can serve up to 8 depending on the size of bowls and amounts used per serving.
