French Onion Soup with Cheese Toasts


The whole family will enjoy this intensely flavorful soup.


  • ½ cup unsalted butter

  • 3 tablespoons all-purpose flour

  • 2 large white onions, chopped into small pieces

  • 4 cups homemade or low-sodium canned chicken stock

  • 4 cups homemade or low-sodium canned beef stock

  • 1 teaspoon salt

  • ¼ teaspoon freshly ground pepper

  • 18 thin slices French baguette

  • 2 cups shredded Swiss cheese (½ pound)


  1. In a large, heavy-bottom saucepan, melt the butter over medium heat. Add flour and chopped onions; saute, stirring occasionally, until onions are soft and translucent, about 15 minutes.

  2. Pour chicken and beef stocks into the saucepan, and stir to combine. Bring mixture to a boil. Reduce heat to low, and simmer 15 minutes. Add salt and pepper.

  3. Heat broiler. Ladle soup into six 16-ounce ovenproof bowls, and float 3 slices of bread on top of each. Sprinkle the cheese over bread slices in each bowl, dividing evenly. Place bowls on a rimmed baking sheet, and broil until cheese is melted and bubbling, about 2 minutes. Let soup cool slightly before serving.

Cook's Notes

If you don't have oven-proof bowls, you can toast the cheese-topped bread slices on a baking sheet under the broiler before adding to the soup.
