Directions
-
Melt the butter in a large heavy-bottomed pot or kettle over medium heat.
-
Add the thinly sliced onions and cook, stirring frequently, until they are deeply golden brown and caramelized.
-
Sprinkle the flour over the onions and cook, stirring constantly, for about 3 minutes to remove the raw flour taste.
-
Slowly pour in the beef broth while stirring constantly to prevent lumps from forming.
-
Bring the soup to a boil, then reduce heat to low, cover, and simmer for 20 minutes.
-
Season the soup with salt and pepper to taste.
-
Preheat the broiler and place 2 slices of French bread in each of 6 heatproof bowls.
-
Top each slice of bread with 1 tablespoon of grated Gruyère cheese.
-
Ladle the hot soup over the bread and cheese in each bowl.
-
Top with any remaining grated cheese.
-
Place the bowls under the broiler about 4 inches from the heat source for 3 minutes, or until the cheese is melted, bubbly, and lightly browned.

Note
For deeper flavor, you can add a splash of dry white wine or sherry after caramelizing the onions and before adding the broth; let it reduce for 2-3 minutes.
If you prefer a vegetarian version, substitute the beef broth with a high-quality vegetable broth.
Gruyère is traditional, but you can substitute with Swiss cheese, Emmental, or a blend of cheddar and Parmesan if needed.
Ensure your serving bowls are oven-safe and heatproof before placing them under the broiler.
Leftover soup stores well in the refrigerator for up to 3 days. Reheat gently on the stove; add the bread and cheese topping fresh when serving for the best texture.
