French Onion Soup

A proper French onion soup is built on one humble vegetable taken to its peak: onions caramelized slowly and patiently for the better part of an hour, until they turn sweet and deeply golden. Only then come the white wine and a rich beef stock that give the broth its depth. A baked cheese baguette adds heartiness and the signature golden crust. Serve it as an elegant dinner or a festive starter.

Step by step process

Preparation

  1. 1

    Peel the onions and cut them in half, then slice them into thin half-moons. Even slices let a proper French onion soup caramelize slowly and evenly.

  2. 2

    Coarsely grate the cheese and cut the baguette into thicker slices so they do not become soggy while baking.

Soup

  1. 3

    Melt the butter in a wide pot and add the onions. Cook over medium to low heat, stirring often, for 35 to 40 minutes until deeply golden.

  2. 4

    Once the onions have softened and developed a caramel aroma, dust them with plain flour and stir for one minute so the flour does not remain raw.

  3. 5

    Pour in the white wine, loosen all the browned bits from the bottom, and let the liquid simmer gently for about 3 minutes.

  4. 6

    Add the beef stock, thyme, bay leaf, and whole peppercorns. Simmer over low heat for about 25 minutes so the flavors can meld.

  5. 7

    Remove the herbs and spices at the end, then season the soup with salt and freshly ground pepper to taste.

Baking and Serving

  1. 8

    Briefly toast the baguette slices in the oven or in a dry pan so they turn lightly golden and keep their structure once the soup is poured over them.

  2. 9

    Pour the hot broth into ovenproof bowls and place the toasted baguette on top. Generously cover with grated Emmental.

  3. 10

    Place the bowls under a hot grill or in the oven and bake for 3 to 5 minutes, until the cheese melts and forms a golden crust.

  4. 11

    Serve immediately while piping hot. The crisp baguette and melted cheese blend beautifully with the rich, intense broth.

More tips:

Do not rush the onions. The long, slow caramelization is what gives the whole soup its sweet, deep flavor.

If you want to deepen the flavor even more, replace part of the stock with a strong homemade beef reduction or a rich meat glaze.
