French Onion Soup with Swiss-Topped Toast Recipe

French Onion Soup with Swiss-Topped Toast Recipe

In my opinion, the key to a delicious French Onion Soup is a dark, savory broth, which you get from beef broth. But, if you want a vegetarian version this is rather hard to do with vegetable broth. To achieve the earthy tones I'm looking for, I've used a few nontraditional ingredients to this soup. I think it is a winner.—Paul DeBenedictis, Reading, Massachusetts
TOTAL TIME: Prep: 30 min. Cook: 1 hour 20 minutes YIELD:6 servings


  • 3 pounds yellow onions
  • 1 pound sweet onions, thinly sliced
  • 2 tablespoons butter
  • 1 tablespoon olive oil
  • 1 teaspoon dried thyme
  • 1 teaspoon brown sugar
  • 1 teaspoon balsamic vinegar
  • 1 tablespoon all-purpose flour
  • 1 can (14-1/2 ounces) vegetable broth
  • 1 can (12 ounces) beer or 12 ounces vegetable broth
  • 1/4 cup white wine or additional vegetable broth
  • 2 tablespoons reduced-sodium soy sauce

  • 1/2 teaspoon coarsely ground pepper
  • 1/4 teaspoon salt
  • 1/8 teaspoon cayenne pepper
  • 6 slices French bread (1 inch thick)
