With its rich, savory broth, caramelized onions, and a perfect topping of melted cheese and crusty bread, French Onion Soup brings together simple ingredients to create a dish that is greater than the sum of its parts.

This dish has its roots in 18th-century France, though its popularity in the U.S. has grown over the years, especially as a winter staple. Whether you’re looking for a meal that will satisfy your hunger after a cold day outside, or simply craving a dish that oozes comfort and warmth, French Onion Soup checks all the boxes.

The History Behind French Onion Soup

The origins of French Onion Soup are somewhat murky, but the dish has been a part of French cuisine for centuries. Historians believe that French Onion Soup began as a humble peasant dish, created from the simple ingredients that were often readily available to the lower classes—onions, bread, and cheese. In fact, onions were so affordable and abundant that they became the backbone of this rustic dish.

The soup became more refined and popular over time, particularly after the 18th century. One famous story suggests that the soup gained prominence when King Louis-Philippe of France visited the home of famous chef, Antonin Carême, and enjoyed a version of French Onion Soup that was made with high-quality ingredients. The dish’s popularity only grew from there, evolving into the rich, complex recipe we know today, complete with the signature melted cheese topping.

Ingredients You’ll Need for French Onion Soup

The beauty of French Onion Soup lies in its simplicity. However, creating the perfect bowl requires some time and patience to allow the ingredients to develop their full, deep flavor. Here are the basic ingredients you’ll need:

• Onions: The star of the show. You’ll need about 4 large yellow onions, sliced thinly. The caramelization of the onions is key to the flavor profile of the soup. As the onions cook down, they transform from sharp and pungent to sweet and golden brown, imparting a deep flavor that serves as the soup’s foundation.
• Butter and Olive Oil: A combination of butter and olive oil is used to cook the onions. Butter adds richness and flavor, while olive oil helps to prevent the butter from burning during the slow cooking process.
• Beef Broth: Traditionally, French Onion Soup is made with beef broth, which adds a hearty, savory base to the soup. Some versions use a mix of beef and chicken broth, but beef broth offers the richest flavor.
• White Wine: A dry white wine is typically added to deglaze the pot after the onions have caramelized. This adds an additional layer of depth to the flavor and enhances the richness of the broth.
• Thyme and Bay Leaves: These herbs are essential for flavoring the broth. Fresh thyme is often preferred, but dried thyme can also be used. Bay leaves add a subtle, aromatic flavor.
• Cheese: The quintessential topping of French Onion Soup is melted cheese. Traditionally, Gruyère cheese is used for its nutty flavor and excellent melting properties. Some recipes may use a combination of Gruyère and Swiss cheese or even add Parmesan for extra depth.
• French Bread: A hearty, crusty French baguette or similar type of bread is sliced and toasted to form a thick, crispy topping for the soup. The bread soaks up the flavorful broth while maintaining its texture under the gooey melted cheese.

The Steps to Make French Onion Soup

1. Caramelize the Onions: Start by heating butter and olive oil in a large pot over medium heat. Add the sliced onions and cook them slowly, stirring occasionally. This process can take anywhere from 30 minutes to an hour, depending on the heat level. The goal is to slowly draw out the sugars in the onions, turning them golden brown and soft. Be patient, as this step is essential to develop the deep, rich flavor that defines French Onion Soup.
2. Deglaze with Wine: Once the onions have caramelized, pour in the white wine and scrape the browned bits off the bottom of the pot. This adds extra flavor to the broth and helps lift all of the savory goodness stuck to the pan.
3. Add the Broth and Herbs: Pour in the beef broth, and add the thyme and bay leaves. Bring the soup to a simmer and cook for another 30 minutes to allow the flavors to meld together. Season with salt and pepper to taste.
4. Prepare the Bread and Cheese: While the soup simmers, prepare the bread. Slice the French baguette into thick slices and toast them in the oven until golden and crispy. Once the bread is ready, grate the Gruyère cheese (about 1-2 cups) for the topping.
5. Assemble the Soup: Once the soup has finished simmering, ladle it into oven-safe bowls. Place a slice of toasted bread on top of each bowl and generously sprinkle the grated Gruyère cheese over the bread. Place the bowls under the broiler for a few minutes until the cheese is bubbly and golden brown.
6. Serve and Enjoy: Once the cheese has melted and browned, your French Onion Soup is ready to be served. Be sure to allow the soup to cool slightly before digging in, as the cheese will be extremely hot. Enjoy the deep, savory broth, the sweet caramelized onions, and the gooey, cheesy topping.

Tips for the Perfect French Onion Soup

• Don’t Rush the Caramelization: The longer you cook the onions, the more flavorful the soup will be. Resist the urge to turn up the heat to speed up the caramelization process. Low and slow is key to achieving the perfect depth of flavor.
• Use High-Quality Broth: Since the broth is the base of the soup, using a high-quality beef broth (or homemade if possible) will elevate the overall flavor. Opt for a broth that is rich and full-bodied.
• Experiment with Cheese: While Gruyère is the traditional choice, you can experiment with different cheeses to add your personal touch. Swiss, Comté, and even fontina can work well as alternatives.
• Serving Options: French Onion Soup is often served as a main dish, but it can also be served as a starter to a larger meal. Pair it with a green salad and a glass of red wine for a complete, satisfying meal.
