  • (1 tablespoon) all-purpose flour

  • (1) bay leaf
  • (4 slices) of baguette
  • (1 cup) grated Gruyère cheese
  • (1/4 cups) chopped fresh parsley

Instructions

  1. 1

    Slice the 4 large onions thinly.

  2. 2

    In a large pot, melt 1/4 cup unsalted butter over medium heat.

  3. 3

    Add the sliced onions to the pot, along with 1 teaspoon sugar, 1 teaspoon salt, and 1/2 teaspoon black pepper. Cook, stirring occasionally, for about 30 minutes until the onions are caramelized and golden brown.

  4. 4

    Sprinkle 1 tablespoon all-purpose flour over the onions and stir for 2 minutes to cook the flour.

  5. 5

    Pour in 8 cups beef broth and 1/2 cup dry white wine, stirring to combine.

  6. 6

    Add 1 teaspoon thyme and 1 bay leaf to the pot. Bring the soup to a boil, then reduce the heat and let it simmer for 30 minutes.

  7. 7

    While the soup simmers, preheat your oven to 400°F (200 °C).

  8. 8

    Place 4 slices of baguette on a baking sheet and toast in the oven for about 5-7 minutes until golden.

  9. 9

    Once the soup is done simmering, remove the bay leaf and ladle the soup into oven-safe bowls. Top each bowl with a slice of toasted baguette and 1/4 cup grated Gruyère cheese.

  10. 10

    Place the bowls on a baking sheet and broil in the oven for 3-5 minutes until the cheese is bubbly and golden brown.
