Soup Base

Method

Soup Preparation

  1. 1

    Sauté the Onions

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

  2. 2

    Add Garlic

    Stir in the minced garlic and cook for an additional 2-3 minutes until fragrant.

  3. 3

    Deglaze with Wine

    Pour in the dry white wine to deglaze the pot, scraping up any browned bits from the bottom. Let it simmer for about 5 minutes until slightly reduced.

  4. 4

    Add Broth and Seasonings

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

Serving Preparation

  1. 5

    Prepare the Baguette

    While the soup is simmering, preheat your oven to 350°F (175°C). Slice the baguette and arrange the slices on a baking sheet. Toast in the oven for about 10 minutes until lightly browned.

  2. 6

    Add Cheese

    Once the soup is ready, remove the bay leaf. Ladle the soup into oven-safe bowls, top with toasted baguette slices, and sprinkle with Gruyère and Parmesan cheese.

  3. 7

    Broil

    Place the bowls under the broiler for about 3-5 minutes until the cheese is bubbly and golden brown. Watch closely to avoid burning.

  4. 8

    Serve

    Carefully remove the bowls from the oven and let them cool for a minute. Serve hot and enjoy your French onion soup!
