Method

Preparation

  1. 1

    Slice the Onions

    Peel and slice the yellow onions into thin, even slices.

  2. 2

    Prep the Bread

    Slice the baguette into 1-inch thick slices and set aside.

Cooking

  1. 3

    Sauté the Onions

    In a large pot, melt the unsalted butter and olive oil over medium heat. Add the sliced onions and cook, stirring frequently until caramelized, about 30-40 minutes.

  2. 4

    Add Liquid Ingredients

    Once the onions are caramelized, add the dry white wine to deglaze the pot, scraping up any bits from the bottom. Cook for another 5 minutes.

  3. 5

    Simmer the Soup

    Add the beef broth, bay leaves, thyme, salt, and black pepper to the pot. Bring to a boil, then reduce heat and let it simmer for 30 minutes.

Final Touches

  1. 6

    Prepare the Topping

    Preheat your oven to 350°F (175°C). Place the baguette slices on a baking sheet and sprinkle with Gruyère and Parmesan cheese.

  2. 7

    Toast the Bread

    Bake the bread in the oven for about 10-15 minutes or until the cheese is melted and bubbly.

  3. 8

    Serve the Soup

    Remove the bay leaves from the soup. Ladle the hot onion soup into bowls, top each bowl with a slice of the cheesy baguette, and serve immediately.
