Ingredients
Scale
Vegetables & Aromatics
- 4 large yellow onions, thinly sliced
- 3 garlic cloves, minced
- 3 sprigs fresh thyme
- Salt, to taste
- Black pepper, to taste
Fats & Liquids
- 2 tablespoons butter
- 1 tablespoon olive oil
- 1/2 cup dry white wine or dry sherry
- 6 cups beef broth or vegetable broth
Bread & Cheese
- 1 French baguette, sliced into 1/2-inch rounds and toasted
- 2 cups Gruyère cheese, grated
Instructions
- Caramelize the Onions: Start by slicing the onions thinly. Cook them slowly in butter and olive oil over low heat, stirring frequently, until they turn golden brown and develop a natural sweetness. This process should take about 30-40 minutes for perfect caramelization.
- Add Garlic and Thyme: Stir in the minced garlic and fresh thyme to the caramelized onions. Cook for another 2 minutes until fragrant, being careful not to burn the garlic.
- Deglaze the Pan: Pour in the dry white wine or sherry to deglaze the pan. Scrape up all the browned bits at the bottom and let the liquid simmer briefly until the alcohol evaporates and the volume reduces slightly.
- Add Broth and Simmer: Add the beef or vegetable broth to the pot. Stir well and bring the soup to a gentle simmer. Let it cook for about 20 minutes to allow the flavors to meld beautifully.
- Prepare the Bread and Cheese: While the soup simmers, slice the French baguette and toast the slices until golden brown. Grate the Gruyère cheese and set aside.
- Assemble and Broil: Ladle the hot soup into oven-safe bowls. Place a toasted baguette slice on top of each and pile on the grated Gruyère cheese. Place the bowls under a broiler until the cheese melts, bubbles, and turns golden brown. Watch carefully to avoid burning.
Notes
- Patience is key: take time to caramelize onions slowly for the richest flavor.
- Use quality broth (homemade or good store-bought) for deeper taste.
- Slice onions uniformly thin to ensure even cooking.
- Watch closely when broiling cheese to prevent burning.
- Authentic Gruyère cheese is essential for traditional flavor and melting quality.
- For a vegetarian option, substitute beef broth with vegetable broth and use vegetarian-friendly cheese.
- For gluten-free variation, replace the baguette with gluten-free bread or toasted polenta slices.
