Ingredients

4 large yellow onions, thinly sliced
4 cups beef stock (or vegetable stock)
1 cup dry white wine
2 tablespoons unsalted butter
2 tablespoons olive oil
1 tablespoon sugar (optional)
2 cloves garlic, minced
1 bay leaf
1 teaspoon fresh thyme (or ½ teaspoon dried thyme)
Salt and black pepper, to taste
1 French baguette, sliced
2 cups grated Gruyère cheese
1 cup grated Parmesan cheese
Chopped fresh parsley, for garnish

Step-by-Step Instructions

Follow these simple steps to create your delicious Gratin de Soupe à l'Oignon à l'Ancienne:

Prep Onions: In a large, heavy-bottomed pot, heat butter and olive oil over medium heat. Add the sliced onions and stir to coat them evenly.
Caramelize Onions: Cook the onions, stirring occasionally, until they become soft and caramelized, about 25-30 minutes. If desired, add sugar to enhance the sweetness.
Add Garlic: Stir in the minced garlic and cook for an additional 1-2 minutes until fragrant.
Pour in Wine: Add the dry white wine and increase the heat to high. Scrape any bits from the bottom and let the wine reduce by half, about 5 minutes.
Add Stock and Herbs: Pour in the beef or vegetable stock, bay leaf, thyme, salt, and pepper. Bring to a boil, then reduce the heat and let simmer for 25 minutes.
Prepare Bread: While the soup is simmering, preheat your oven to 350°F (175°C). Arrange the baguette slices on a baking sheet and toast them in the oven until crispy, about 10 minutes.
Combine Cheeses: In a bowl, mix the grated Gruyère and Parmesan cheeses together.
Assemble Gratin: Remove bay leaf from the soup. Ladle the soup into oven-safe bowls, topping each with a piece of toasted baguette and a generous amount of the cheese mixture.
Broil: Place the bowls on a baking sheet and broil in the oven for 3-5 minutes or until the cheese is bubbly and golden.
Garnish: Carefully remove the hot bowls and sprinkle with chopped parsley before serving.

Wine Pairing: A crisp white wine complements the savory notes, while a rich red wine adds depth to the meal.

Additional Tips
