Equipment

  • Large pot or Dutch oven
  • Wooden spoon
  • Cheese grater
  • Oven-safe soup bowls (for broiling)
  • Baking sheet (for toasting bread)

Ingredients
  

  • 4 tablespoons unsalted butter
  • 6 large yellow onions thinly sliced
  • 2 cloves of garlic minced
  • 1 teaspoon sugar
  • 2 tablespoons all-purpose flour
  • 1/2 cup dry white wine
  • 6 cups beef broth low sodium preferred
  • 1 bay leaf
  • 1/2 teaspoon dried thyme
  • Salt and freshly ground black pepper to taste
  • 1 baguette sliced and toasted
  • 1 1/2 cups grated Gruyère cheese Swiss or Parmesan can also be used

Instructions
 

Caramelize the Onions:

  • In a large pot or Dutch oven, melt the butter over medium heat.
  • Add the sliced onions and cook, stirring occasionally, until they are soft and caramelized, about 30-40 minutes.
  • Stir in the garlic and sugar, and cook for another 5 minutes.

Make the Soup Base:

  • Sprinkle the flour over the onions and stir to coat. Cook for about 2 minutes.
  • Slowly add the white wine, scraping up any browned bits from the bottom of the pot.
  • Add the beef broth, bay leaf, and thyme. Bring to a simmer.
  • Season with salt and pepper. Reduce heat and simmer for about 30 minutes.

Prepare the Bread and Cheese:

  • Preheat your oven's broiler.
  • Place the toasted baguette slices on a baking sheet and sprinkle generously with grated cheese.
  • Broil until the cheese is melted and bubbly, about 3-5 minutes.

Assemble and Serve:

  • Ladle the hot soup into bowls.
  • Top each bowl with a slice or two of the cheesy bread.
  • Serve immediately and enjoy!

Tips:

  • For a vegetarian version, substitute beef broth with a rich vegetable broth.
  • To enhance the flavor, consider adding a splash of sherry or brandy to the soup before serving.
  • If you don't have oven-safe soup bowls, you can toast the bread with cheese separately and add it on top of the soup when serving.

Notes

  • For a vegetarian version, use a rich vegetable broth instead of beef broth.
  • Adding a splash of sherry or brandy enhances the flavor.
  • If you don't have oven-safe soup bowls, toast the bread with cheese separately and add it to the soup when serving.
  • Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat on the stove over medium heat.
