Ingredients
Scale
Soup
- 4 large onions, thinly sliced
- 2 tablespoons butter
- 4 cups beef broth
- 1 teaspoon thyme
- 1 tablespoon flour
- Salt and pepper to taste
Toppings
- 4 slices baguette
- 1 cup Gruyère cheese, shredded
Instructions
- Caramelize the onions: In a large pot, melt the butter over medium heat. Add the thinly sliced onions and cook, stirring occasionally, until they become golden brown and caramelized, about 25 minutes.
- Make the roux: Sprinkle the flour over the caramelized onions and stir to combine. Cook for an additional 2 minutes to create a slight roux which will help thicken the soup.
- Add broth and thyme: Pour in the beef broth and add the thyme. Bring the soup to a boil, then reduce the heat to a simmer and cook for 15 minutes to blend the flavors.
- Season the soup: Taste and season the soup with salt and pepper according to your preference.
- Prepare the baguette: While the soup simmers, toast the baguette slices in the oven until golden and crispy. Once toasted, top each slice with shredded Gruyère cheese.
- Serve: Ladle the hot soup into bowls and place a cheese-covered baguette slice on top of each serving. Serve immediately and enjoy the delicious melting cheese with the rich onion broth.
Notes
- For a vegetarian version, substitute beef broth with vegetable broth.
- Caramelizing onions slowly is key for deep flavor—don’t rush this step.
- Baguette slices can be broiled instead of toasted for quicker melting of cheese.
- Gruyère cheese can be substituted with Swiss cheese if unavailable.
- Use fresh thyme for best flavor, but dried thyme works well too.
