French Onion Soup with Swiss-Topped Toast

In my opinion, the key to a delicious French onion soup is a dark, savory broth, which you get from beef broth. If you want a vegetarian version, it can be hard to do with vegetable broth. To achieve the earthy tones I'm looking for, I've used a few nontraditional ingredients for this soup. I think it is a winner. —Paul DeBenedictis, Reading, Massachusetts
