Ingredients
  

4 large yellow onions, thinly sliced

4 tablespoons unsalted butter

1 tablespoon olive oil

1 teaspoon sugar

1 teaspoon salt

1/2 teaspoon black pepper

2 garlic cloves, minced

1 tablespoon all-purpose flour

8 cups beef stock (preferably homemade or low sodium)

1 cup dry white wine (like Sauvignon Blanc)

1 tablespoon fresh thyme leaves (or 1 teaspoon dried thyme)

1 bay leaf

1 French baguette, sliced into 1-inch thick rounds

2 cups grated Gruyère cheese

Fresh parsley, chopped (for garnish)

Instructions
 

Cook the Onions: In a large heavy-bottomed pot, melt the butter and olive oil over medium heat. Add the sliced onions, sugar, salt, and pepper, stirring to combine. Cook for about 30-40 minutes, stirring occasionally, until the onions become deeply caramelized and golden brown.

    Add Garlic and Flour: Once the onions are caramelized, stir in the minced garlic and cook for an additional minute until fragrant. Sprinkle the flour over the onions and stir well to coat; cook for 2 more minutes to eliminate the raw flour taste.

      Deglaze the Pot: Pour in the white wine, scraping the bottom of the pot to release any stuck bits. Allow the wine to simmer for about 5 minutes until slightly reduced.

        Add Broth and Herbs: Pour in the beef stock, adding the fresh thyme and bay leaf. Bring the soup to a simmer, reduce the heat to low, and let it simmer gently for 25-30 minutes to develop the flavors. Remove the bay leaf before serving.

          Prepare the Baguette: While the soup is simmering, preheat your oven to 400°F (200°C). Arrange the baguette slices on a baking sheet and toast them in the oven for about 5-7 minutes, or until golden and crisp.

            Assemble the Soup: Ladle the hot soup into oven-safe bowls. Place the toasted baguette slices on top of the soup, then generously sprinkle the grated Gruyère cheese over the bread.

              Broil: Place the bowls on a baking sheet and put them in the oven under the broiler for 3-5 minutes, or until the cheese is bubbly and golden brown. Keep a close eye to prevent burning!

                Serve: Carefully remove the bowls from the oven, garnish with freshly chopped parsley, and enjoy while hot. Pair with a side salad for a complete meal.
