Introduction
French Onion Soup is a timeless dish that originated in France and has become a beloved comfort food worldwide. The key to this classic soup lies in slowly caramelizing the onions until they turn a deep, golden brown, which creates a rich, sweet, and complex flavor. Combined with a savory broth, a splash of wine, and topped with toasted bread and gooey melted cheese, this soup is the perfect way to warm up on a chilly evening. Whether served as a starter or a main course, French Onion Soup always impresses with its depth of flavor and comforting aroma.
Ingredients
- 4 large yellow onions, thinly sliced
- 3 tablespoons unsalted butter
- 1 tablespoon olive oil
- 1 teaspoon salt
- 1 teaspoon sugar (optional, to help caramelize the onions)
- 1/2 cup dry white wine or dry sherry
- 8 cups beef broth
- 1 bay leaf
- 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme)
- Salt and black pepper, to taste
- 1 baguette, sliced
- 2 cups grated Gruyère cheese (or Swiss cheese)
Instructions
- Caramelize the Onions: In a large pot or Dutch oven, melt the butter with the olive oil over medium heat. Add the sliced onions and stir to coat. Cook the onions for about 30-40 minutes, stirring occasionally, until they are soft and a deep golden brown. Add the sugar during the cooking process if desired to help with caramelization.
- Deglaze with Wine: Pour in the white wine or dry sherry and scrape up any browned bits from the bottom of the pot. Let the wine cook down for 2-3 minutes until mostly evaporated.
- Add Broth and Herbs: Stir in the beef broth, bay leaf, and thyme. Bring the mixture to a boil, then reduce the heat and let it simmer for 20-30 minutes. Season with salt and black pepper to taste. Remove the bay leaf before serving.
- Prepare the Bread: While the soup simmers, preheat your oven’s broiler. Place the baguette slices on a baking sheet and toast under the broiler for 1-2 minutes per side, or until golden brown.
- Assemble and Broil: Ladle the soup into oven-safe bowls. Place a slice or two of toasted baguette on top of each bowl and sprinkle generously with grated Gruyère cheese. Place the bowls on a baking sheet and broil for 2-3 minutes, or until the cheese is melted and bubbly.
- Serve: Carefully remove the bowls from the oven and let them cool slightly before serving. Enjoy!
Cook Notes & Tips
- Caramelizing Onions: Caramelizing the onions properly is key to the flavor of this soup. Take your time and cook them slowly until they reach a deep golden brown color.
- Broth: Beef broth gives the soup its traditional depth of flavor, but you can also use a combination of beef and chicken broth for a milder taste.

Variations

- Cheese Blend: Use a blend of cheeses like Gruyère and Parmesan for extra flavor.
