Main Ingredients
- 4 large yellow onions, thinly sliced
- 4 tablespoons butter
- 6 cups beef broth (or vegetable broth for vegetarian version)
- 1/2 cup dry white wine (optional)
- 1 tablespoon Dijon mustard
- 2 teaspoons fresh thyme leaves
- 6 slices French bread, toasted
- 2 cups shredded Swiss or Gruyere cheese
- Caramelize the Onions: Thinly slice the yellow onions. Melt the butter in a large pot over medium-low heat. Add the onions and cook slowly, stirring frequently, for about 40 to 50 minutes until they turn golden brown and develop a rich, sweet flavor without burning.
- Deglaze and Simmer: Add a splash of white wine to the pot to deglaze, scraping up any browned bits. Stir in the beef broth, Dijon mustard, and fresh thyme. Bring the soup to a simmer and cook gently for 20 to 30 minutes to meld the flavors.
- Prepare the Bread and Cheese: While the soup simmers, slice the French bread and toast it until crisp. Grate the Swiss or Gruyere cheese to use as a topping.
- Assemble and Broil: Ladle the hot soup into oven-safe bowls. Place a slice of toasted bread on top of each bowl, then generously pile the grated cheese over the bread. Place the bowls under the broiler until the cheese is melted, bubbly, and golden brown, forming a delicious crust.
Notes
- Cook onions low and slow to prevent burning and ensure perfect caramelization.
- Use high-quality beef broth for the best flavor depth—homemade or store-bought both work well.
- Toast bread thoroughly to keep it from becoming soggy when added to the soup.
- Watch the broiler carefully to achieve a golden bubbly cheese topping without burning.
- Fresh thyme enhances aroma and flavor better than dried herbs.
