    Top each slice of bread with 1 tablespoon of grated Gruyère cheese.
  9. 9
    Ladle the hot soup over the bread and cheese in each bowl.
  10. 10

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.

The original recipe source is from a 1951 Gourmet Magazine favorite.
