Instructions

1

Slice the onions (1 kg) into thin half-moons. In a wide pot, melt the butter (60 g) and caramelize the onions over medium-low heat for 40–45 minutes, stirring often, until soft and golden brown.

2

Sprinkle the onions with flour (1 tbsp) and cook for 1 minute, stirring constantly.

3

Pour in the dry white wine (150 ml), stir, scraping up the browned bits from the bottom of the pot with a spatula, and simmer for 2–3 minutes.

4

Add the hot beef broth (1 L), along with the bay leaves (2) and thyme (2 sprigs), then season with salt and pepper to taste. Simmer over low heat, covered, for 20–25 minutes.

5

Arrange the baguette slices (8) on a baking sheet and toast in the oven at 180°C for 10–12 minutes until crisp.

6

Ladle the hot soup into oven-safe bowls, top with the toasted baguette slices, and generously sprinkle with grated Gruyère (200 g).

7

Place the bowls under the broiler for 3–5 minutes, until the cheese melts and turns golden brown.
