French Onion Soup Chef John Recipe

His method involves slow caramelization of the onions to bring out their natural sweetness, followed by simmering them in a deeply flavorful broth.

The key to success lies in patience; caramelizing onions to that perfect golden-brown color can take time, but the result is worth every minute.

Ingredients Needed

Here’s what you’ll need for Chef John’s French Onion Soup:

• Yellow onions (5-6 medium-sized): The star of the show. They are sweet and mellow when caramelized, giving the soup its signature flavor.
• Butter (3 tablespoons): For sautéing the onions and creating a luscious base.
• Olive oil (2 tablespoons): Adds a hint of richness to the soup.
• Beef broth (6 cups): This is where much of the flavor comes from. Chef John uses a quality beef broth for that deep, savory taste. You can also use a mix of beef and chicken broth for a lighter version.
• Dry white wine (1 cup): Wine adds acidity and depth to the soup, balancing out the sweetness of the onions.
• Thyme (3-4 sprigs or 1 tsp dried): A classic herb in French onion soup, contributing an earthy flavor.
• Bay leaves (2): Adds a subtle aroma to the broth.
• Sugar (1 teaspoon): A little sugar helps speed up the caramelization process and enhances the sweetness of the onions.
• Salt and pepper (to taste): Essential for bringing out all the flavors.
• French baguette (1 loaf, sliced into 1-inch thick slices): These slices are toasted and placed on top of the soup for a crispy, delicious topping.
• Gruyère cheese (1 ½ cups, shredded): The cheese of choice for French Onion Soup. It melts beautifully and adds a nutty flavor. Some people also add a mix of Gruyère and Swiss cheese.

Cooking Instructions

1. Caramelizing The Onions

   • Start by slicing the onions thinly. You can use a mandolin for even slices, but be careful, as they’re sharp!
   • In a large pot or Dutch oven, heat the butter and olive oil over medium heat. Once melted, add the onions.
   • Sprinkle a pinch of salt and sugar over the onions. The salt helps release moisture, and the sugar accelerates the caramelization process.
   • Stir the onions occasionally. This part requires patience-cook the onions for about 45 minutes, or until they turn a deep golden-brown. This slow process brings out the sweetness of the onions, which is key to the flavor of the soup.

2. Deglaze With Wine

   • Once your onions are beautifully caramelized, pour in the white wine, scraping the bottom of the pot to release any caramelized bits stuck to the surface. Let the wine cook down until it’s almost completely evaporated.

3. Add Broth And Herbs

   • Pour in the beef broth and add the thyme and bay leaves. Bring the soup to a simmer, and let it cook for 30-40 minutes. This allows the flavors to meld together.

4. Final Seasoning

   • Taste the soup and adjust the seasoning with salt and pepper if needed. You want the broth to have a balanced, savory flavor with a touch of sweetness from the caramelized onions.

5. Prepare The Toasted Bread

   • While the soup is simmering, preheat your oven to 350°F (175°C). Place the baguette slices on a baking sheet and toast them in the oven for 10-15 minutes until they’re golden and crispy.

6. Assemble The Soup

   • Ladle the soup into oven-safe bowls or crocks. Place one or two of the toasted baguette slices on top of the soup, then generously cover with the shredded Gruyère cheese.

7. Melt The Cheese

   • Place the bowls under a broiler for 2-3 minutes, or until the cheese is melted, bubbly, and lightly browned. Keep an eye on it to prevent burning.

Ingredient Insights

• Onions: While yellow onions are the classic choice, you can experiment with other types, like red or white onions. Yellow onions, however, provide the best balance of sweetness and umami when caramelized.
• Beef Broth: For the most authentic flavor, use homemade beef broth, but store-bought is perfectly fine. Opt for low-sodium versions if you want to control the seasoning.
• Gruyère Cheese: This Swiss cheese is the gold standard for French Onion Soup because of its ability to melt beautifully without separating. If you’re in the mood for a twist, you can mix it with mozzarella for added stretch.

Expert Tips

• Caramelization Patience: One of the keys to success in this recipe is the slow, patient caramelization of the onions. Don’t rush it! If the onions start to burn, lower the heat.
• Broth Depth: To achieve a fuller flavor, use a combination of beef and chicken broth, or even throw in a couple of tablespoons of demi-glace if you want to go all out.
• Cheese Crust: Don’t be afraid to pile on the cheese-after all, the gooey, browned crust is one of the highlights of the dish! Use a broiler-safe dish, and be sure the cheese is browned and bubbly before serving.
• Stale Bread: Use slightly stale bread for the topping. It holds up better to the broth and absorbs the flavors without turning soggy too quickly.

Recipe Variations

• Vegetarian French Onion Soup: If you want to skip the beef broth, vegetable broth can be a suitable alternative. You’ll lose some of the depth of flavor, but it still makes for a delicious soup.
• Bacon-Topped: For an added savory crunch, try topping the soup with crispy bacon bits along with the cheese.
• Herb Variations: While thyme and bay leaves are classic, you can also experiment with other herbs like rosemary or oregano for a unique twist.
• Crouton Style: Instead of using slices of baguette, you could make croutons by cutting the bread into small cubes and toasting them with garlic and butter for a flavorful alternative.
