This French onion soup recipe is a classic restaurant dish that’s so easy to prepare at home.  The secret is in caramelizing the onions to bring out their natural sweetness.  Start out with Vidalia onions for the sweetest flavor and don’t rush the cooking process to be sure you get every bit of savory, sweet flavor.  Beef broth adds an underlying richness while white wine brings a bright acidity to the soup.  Serve in oven-safe crocks and pop under the broiler just until the cheese is perfectly melted.  Perfection!

Ingredients

cost per recipe: $4.72

  • 1 tablespoon vegetable oil
  • 2 1/2 large onion, cut in half and thinly sliced (about 2 1/2 cups)
  • 1/4 teaspoon sugar
  • 2 tablespoons all-purpose flour
  • 3 1/2 cups Swanson® Beef Broth or 50% Less Sodium Beef Broth
  • 1/4 cup dry white wine or vermouth
  • 4 slices French bread, toasted
  • 1/2 cup shredded Swiss cheese

Instructions

  • Tips

    • Time-Saving Tip: Use a food processor with slicing attachment to slice the onions for ease in preparation.
    • Ingredient Note: For even more flavor, try rubbing the French bread with a garlic clove and topping it with the cheese before toasting.
  • Step 1

    Heat the oil in a 4-quart saucepot over medium heat. Add the onions. Reduce the heat to low. Cover and cook for 15 minutes. Uncover the saucepot.

  • Step 2

    Increase the heat to medium. Add the sugar and cook for 15 minutes or until the onions are golden. Stir the flour in the saucepot and cook and stir for 1 minute. Stir in the broth and wine and heat to a boil. Reduce the heat to low and cook for 10 minutes.

  • Step 3

    Divide the soup among 4 bowls. Top each with a bread slice and cheese.

    I cant stand the taste of alcohol cooked or drank uncooked so I used the beef broth instead defin carmelized onions n used a homemade crouton w Italian or u can use French bread then on top ur favorite cheese all over and under broiler for a few moments til dripping melted cheese is all over. Provolone is great parmesan or a form of swiss gruyere cheese my favorite on this but expensive provolone is a gr8 sub. All r fabulous on top something w a little extra flavor to cut just onions n broth. Doesnt get mundane that way. Delicious.

    I mixed it up a bit to make it better. When adding the Sherry, I added 1 1/2 cup Coganc/Hennessy and let them simmer with the onions for 5 minutes. Then added 2 cups dry white wine and let them simmer together for 15 minutes before adding the Beef Broth. If you can find Veal Broth, substitute half beef for veal. These combinations make the unique flavor. I PROMISE!!! :)
