Whether you’re a seasoned chef or a home cook looking to elevate your repertoire, this step-by-step guide will help you master the art of French Onion Soup.
Ingredients
- 6 large yellow onions, thinly sliced
- 3 tablespoons unsalted butter
- 2 tablespoons olive oil
- 1 teaspoon sugar
- 4 cloves garlic, minced
- 1/2 cup dry white wine or sherry
- 8 cups beef or vegetable stock
- 2 bay leaves
- 4 sprigs of fresh thyme (or 1 teaspoon dried thyme)
- 1 teaspoon salt (adjust to taste)
- 1/2 teaspoon black pepper
- 1 baguette, sliced into rounds
- 1 ½ cups grated Gruyère cheese (or a mix of Gruyère and Parmesan)
Preparation
Step 1: Caramelize the onions
In a large pot or Dutch oven, heat butter and olive oil over medium heat. Add the sliced onions and stir to coat. Sprinkle with sugar to enhance caramelization. Cook, stirring occasionally, for 25–30 minutes, until the onions are deeply golden and tender.
Step 2: Add garlic and deglaze
Stir in the minced garlic and cook for 1–2 minutes until fragrant. Pour in the white wine or sherry, scraping up any browned bits from the bottom of the pot. Simmer for 3–5 minutes until the liquid reduces slightly.
Step 3: Add stock and seasonings
Pour in the beef or vegetable stock and add bay leaves and thyme. Season with salt and black pepper. Bring the soup to a boil, then reduce the heat to low and let it simmer uncovered for 30–40 minutes to allow the flavors to meld.
Step 4: Prepare the bread topping
While the soup simmers, preheat the oven to 375°F (190°C). Arrange baguette slices on a baking sheet and toast for 5 minutes on each side until golden. Remove from the oven and set aside.
Step 5: Assemble and broil
Ladle the soup into oven-safe bowls. Place a toasted baguette slice on top of each bowl and sprinkle generously with grated Gruyère cheese. Place the bowls under the broiler for 2–3 minutes, or until the cheese is melted and bubbly.
Variation
Vegetarian French Onion Soup: Use vegetable stock instead of beef stock for a vegetarian-friendly version. Creamy Onion Soup: Add a splash of heavy cream to the broth for a richer texture. Wine-Free Option: Replace white wine with apple cider or omit it entirely for a non-alcoholic version.
Cooking Notes
Use sweet onions or yellow onions for the best caramelization. For a stronger cheese flavor, mix Gruyère with a bit of sharp cheddar. The soup can be made ahead of time and reheated just before serving.
Serving Suggestions
Serve French Onion Soup as a standalone dish with a side salad for a complete meal. Pair it with a glass of dry white wine or a light red like Pinot Noir. Add a sprinkle of fresh thyme or parsley for a touch of freshness before serving.
Tips
Thinly slicing the onions ensures even cooking and proper caramelization. Stir the onions frequently while caramelizing to prevent burning. For an extra crunchy bread topping, double-toast the baguette slices before assembling the soup.
