- Cook Time: 1 hour 30 minutes (including caramelizing onions)
- Total Time: 1 hour 45 minutes
Yield
Serves 4 hearty bowls
Difficulty Level
Medium – Requires patience and attention to detail, especially during the caramelization process
Ingredients
- 5 large yellow onions, thinly sliced
- 4 tablespoons unsalted butter
- 1 tablespoon olive oil
- 2 cloves garlic, minced
- 1 teaspoon sugar
- 1/2 cup dry white wine (optional)
- 6 cups beef broth (preferably homemade or high-quality store-bought)
- 1 bouquet garni (thyme sprigs, bay leaf, and parsley stems tied together)
- Salt and freshly ground black pepper, to taste
- Baguette slices, toasted
- 2 cups grated gruyère cheese (or a mix of Gruyère and Emmental)
- 1 teaspoon balsamic vinegar (optional for depth)
Instructions
- heat butter and olive oil in a large heavy-bottomed pot over medium heat untill melted and shimmering.
- Add the thinly sliced onions and sprinkle in the sugar. Stir to coat the onions evenly; this will enhance caramelization.

- Pour in the dry white wine to deglaze the pan, stirring to scrape up any flavorful browned bits from the bottom. Let it reduce by half (about 3 minutes).
- Add the beef broth and the bouquet garni.Bring the soup to a gentle simmer, then reduce heat to low. Let it cook uncovered for 30 minutes, allowing flavors to meld and the broth to deepen.
- Season with salt, freshly ground black pepper, and a splash of balsamic vinegar if using.Remove the bouquet garni before serving.
- preheat your oven’s broiler. Ladle the soup into oven-safe bowls. Top each with toasted baguette slices and generous amounts of grated Gruyère.
- Broil until the cheese melts and bubbles,developing a golden-brown crust-about 2-4 minutes. Watch closely to avoid burning.
- Serve instantly, piping hot and irresistible.
