Ingredients
Scale
Soup
- 4 large yellow onions, thinly sliced
- 3 tablespoons unsalted butter
- 1 tablespoon olive oil
- 1 teaspoon sugar
- 2 garlic cloves, minced
- 6 cups beef broth
- 1/2 cup dry white wine (optional)
- 1 teaspoon Worcestershire sauce
- 1/2 teaspoon dried thyme
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
Toppings
- 1 baguette sliced into 1-inch rounds
- 1 1/2 cups shredded Gruyère cheese
Instructions
- Caramelize Onions: In a large pot or Dutch oven, melt the butter with olive oil over medium heat. Add the sliced onions and sugar, cooking slowly while stirring often for about 25–30 minutes until the onions are deeply caramelized and golden brown.
- Add Garlic: Stir in the minced garlic and cook for 1 minute until fragrant to enhance the flavor base of the soup.
- Deglaze with Wine: Pour in the dry white wine if using and simmer for 2–3 minutes to reduce slightly, which adds depth to the broth.
- Simmer Soup: Add the beef broth, Worcestershire sauce, dried thyme, salt, and black pepper. Bring the mixture to a gentle boil, then reduce the heat to low and simmer for 15 minutes to meld the flavors.
- Toast Bread: While the soup simmers, toast the baguette slices in the oven until they are lightly crisp and golden to add texture to the final dish.
- Assemble and Broil: Ladle the hot soup into oven-safe bowls, place a slice or two of toasted baguette on top of each, and sprinkle generously with shredded Gruyère cheese. Place the bowls under a broiler for 2–3 minutes until the cheese is fully melted and bubbly.
- Serve: Carefully remove the bowls from the oven (they will be hot) and serve the classic French onion soup immediately for a delicious and warming experience.
Notes
- For a richer flavor, use a combination of beef and chicken broth.
- If Gruyère cheese is unavailable, Swiss cheese or mozzarella can be substituted.
- Exercise caution when broiling the soup bowls as they become very hot to avoid burns.
- To make this soup vegetarian, substitute beef broth with vegetable broth and omit Worcestershire sauce.
