Ingredients

  • – 2 large yellow onions, quartered and thinly sliced (300g)
  • – 2 red onions, quartered and thinly sliced (300g)
  • – 4 leeks, root ends and dark-green tops lopped off, leeks sliced 1/4-inch thin, and washed (400g)
  • – 1 tablespoon (15g) unsalted butter
  • – 1 tablespoon (15 ml) olive oil
  • – 2 tablespoons (15g) unbleached all-purpose flour
  • – 8 cups (1.9 L) vegetable or chicken stock
  • – 1 tablespoon (15 ml) Worcestershire sauce, [Editor’s Note: or a splash of fortified juice]
  • – 1 teaspoon (5 ml) salt
  • – 1/2 teaspoon (3 ml) freshly ground black pepper
  • – 1 day-old baguette
  • – 1/2 cup grated Parmigiano-Reggiano cheese (50g)
  • – 1/2 cup grated Gruyère cheese (or substitute Comté, Emmentaler, mozzarella, young Manchego, or another melting cheese), plus more as needed (50g)


Instructions

  1. In a large pot on medium-high heat, cook the yellow onions, red onions, and leeks with the butter and olive oil, stirring occasionally to prevent sticking and burning, until they start to soften and reduce in volume, around 5 to 10 minutes.
  2. Lower the heat to medium or medium-low, and continue cooking the onions for roughly an hour until they turn a caramel color and become almost mushy. Make sure they don’t burn by adjusting the heat or adding a splash of water if needed.
  3. Dust the caramelized onions with flour, stirring continuously to avoid lumps, and cook for an additional 5 minutes to remove the raw flour taste.
  4. Add the stock to the onions, raise the heat to bring it to a boil, then lower to a simmer for 30 minutes. Mix in the Worcestershire sauce, salt, and pepper, and adjust the flavors as needed.
  5. Set your oven to 350°F (175°C). Cut the baguette into thick slices, coat both sides with olive oil, arrange them on a baking sheet, and bake until the bread becomes dry and the edges turn golden. Prepare the broiler.
  6. Before serving, mix in the Parmigiano-Reggiano, ensuring to add it at the end to prevent it from sinking and burning. Serve the hot soup in heatproof bowls, placing a baked bread slice in each. Sprinkle Gruyère over the bread slices and broil until the cheese is bubbly and golden.

Notes

  • Consider caramelizing the onions ahead of time and refrigerating them until needed.
  • Experiment with various types of melting cheese for a unique soup flavor.
  • For a vegetarian twist, use vegetable stock in place of chicken stock.

Creating French Onion Soup with Melted Cheese

Fundamentals

French Onion Soup with Melted Cheese is a beloved classic, known for its deep flavors and comforting textures. At its core, this dish is about the harmony between caramelized onions and gooey, melted cheese. The combination creates a rich, savory experience that many have cherished for generations.

The key to this soup’s success lies in the quality of its ingredients. Yellow onions, red onions, and leeks form the aromatic base, while a blend of Parmigiano-Reggiano and Gruyère cheese crowns the dish. These elements come together to create a soup that’s as satisfying as it is flavorful.

Preparation/setup

Begin by preparing your onions and leeks. Thinly slice the yellow and red onions, along with the leeks, ensuring they’re clean and free of grit. This preparation step sets the stage for the caramelization process, which is crucial for developing the soup’s depth of flavor.

In a large pot, heat a tablespoon of unsalted butter and olive oil over medium-high heat. Add the sliced onions and leeks, stirring occasionally to prevent sticking. This initial cooking phase should take about 5 to 10 minutes, allowing the ingredients to soften and release their natural sweetness.

Mastering the Art of Onion Caramelization

Technique

Caramelizing onions is an art form that requires patience. After the initial softening, lower the heat to medium or medium-low. Continue cooking the onions for about an hour, stirring occasionally. This slow process transforms the onions into a caramel-colored, almost mushy texture, unlocking a depth of flavor that’s essential for French Onion Soup with Melted Cheese.

To prevent burning, adjust the heat as needed or add a splash of water. This careful attention ensures your onions develop a rich, sweet flavor without any bitterness.

French Onion Soup with Melted Cheese

Tips/tricks

For evenly caramelized onions, use a wide pot to allow for maximum surface area. This helps the onions cook evenly and prevents overcrowding, which can lead to steaming instead of caramelizing. Additionally, stirring frequently and monitoring the heat closely are key to preventing burning.

Once the onions reach the desired caramelization, dust them with unbleached all-purpose flour. Stir continuously to avoid lumps, and cook for an additional five minutes to remove any raw flour taste before moving on to the next step.

Enhancing Flavor and Texture

Perfecting results

After the flour has cooked, add 8 cups of vegetable or chicken stock to the pot. Increase the heat to bring the mixture to a boil, then reduce it to a simmer for about 30 minutes. This allows the flavors to meld, resulting in a soup that’s both rich and comforting.

For additional depth, stir in a tablespoon of Worcestershire sauce, salt, and freshly ground black pepper. Adjust these seasonings to taste, ensuring the soup is balanced and flavorful.

Troubleshooting/variations

If your soup lacks depth, consider simmering it for a bit longer to intensify the flavors. For those who prefer a sweeter note, a splash of fortified juice can be a delightful addition. Remember, the key is to achieve a harmonious blend of sweet and savory.

Serving and Storing Your Masterpiece

Serving/presentation

Set your oven to 350°F (175°C) and prepare a day-old baguette by slicing it thickly. Coat both sides with olive oil and bake until the bread is dry and golden at the edges. This bread will serve as a delicious base for your soup, absorbing the flavors and adding a delightful crunch.

Before serving, mix Parmigiano-Reggiano into the hot soup. This cheese adds a nutty richness that elevates the dish. Serve the soup in heatproof bowls, each topped with a slice of baked bread. Sprinkle Gruyère cheese generously over the bread, then broil until the cheese is bubbly and golden.
