Follow this recipe to create a restaurant-quality French Onion Soup right in your own kitchen.
Ingredients:
- 4 large yellow onions, thinly sliced: The star of the dish, these onions become sweet and deeply flavorful when caramelized.
- 3 tablespoons unsalted butter: Helps to caramelize the onions, giving them a rich, buttery flavor.
- 1 tablespoon olive oil: Adds a slight fruity note and prevents the butter from burning during the caramelization process.
- 1 teaspoon sugar: Enhances the natural sweetness of the onions and aids in the caramelization process.
- 8 cups beef broth: Provides a savory, robust base for the soup.
- 1/2 cup dry white wine: Adds depth and acidity, balancing the sweetness of the onions.
- 1 bay leaf: Infuses the soup with a subtle, earthy flavor.
- 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme): Brings a hint of herbal freshness to the broth.
- Salt and pepper to taste: Essential for seasoning and enhancing the flavors.
- 1 baguette, sliced into 1-inch pieces: The bread forms the base for the cheesy topping, soaking up the broth.
- 2 cups shredded Gruyère cheese: A nutty, melty cheese that crowns the soup with a golden, bubbly layer of goodness.
Instructions:
1. Caramelize the Onions:
- In a large, heavy-bottomed pot or Dutch oven, melt the 3 tablespoons of unsalted butter with 1 tablespoon of olive oil over medium heat. Once the butter has melted, add the thinly sliced onions.
- Sprinkle the onions with 1 teaspoon of sugar and a pinch of salt to draw out their moisture and enhance their sweetness. Cook the onions, stirring occasionally, for about 25-30 minutes. The onions should gradually soften, turn golden brown, and develop a rich caramel color. If the onions are browning too quickly, reduce the heat to prevent burning.
2. Deglaze the Pot:
- Once the onions are deeply caramelized, pour in the 1/2 cup of dry white wine. Stir well, scraping up any browned bits from the bottom of the pot. Let the wine simmer for a few minutes until it has mostly evaporated, leaving behind its flavor.
3. Add the Broth and Herbs:
- Pour in the 8 cups of beef broth, stirring to combine it with the onions. Add the bay leaf and the thyme (either fresh or dried) to the pot. Season with salt and pepper to taste.
- Bring the soup to a boil, then reduce the heat to low. Cover the pot and let the soup simmer gently for about 30 minutes, allowing the flavors to meld together. Taste and adjust the seasoning with more salt and pepper if needed.
4. 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 10 minutes, or until they are golden brown and crispy. This will prevent them from becoming too soggy when placed in the soup.
5. Assemble the Soup:
- Once the soup is ready, remove the bay leaf and discard it. Ladle the hot soup into oven-safe bowls or crocks. Place a toasted baguette slice on top of each bowl of soup, and generously sprinkle the shredded Gruyère cheese over the bread.
6. Broil the Cheese:
- Place the bowls on a baking sheet and put them under the broiler in your oven. Broil for 2-4 minutes, or until the cheese is melted, bubbly, and golden brown. Keep a close eye on the bowls to prevent the cheese from burning.
7. Serve:
- Carefully remove the bowls from the oven (they will be hot!). Allow them to cool slightly before serving. The cheese should form a beautiful, gooey layer on top, with the bread soaking up the rich broth underneath.
Tips and Variations:
- Cheese Alternatives: While Gruyère is the traditional choice, you can also use other cheeses like Emmental, Comté, or even a sharp cheddar for a different flavor profile.
- Vegetarian Option: To make a vegetarian version of this soup, simply replace the beef broth with a high-quality vegetable broth.
- Thicker Soup: If you prefer a thicker consistency, you can add a tablespoon of flour to the caramelized onions before adding the broth. Cook the flour for a minute or two to eliminate the raw taste, then proceed with the recipe.
