Directions

  1. Chop the onions and sauté them in butter melted in a pan, preferably a cast-iron pan, or at the very least, an enamel or steel pan.
  2. By ensuring they are not overcooked, simply softening them slightly is enough.
  3. Next, add a tablespoon of flour and mix well, keeping the heat very low.
  4. Add salt and pepper, preferably white, as well as one litre of water; bring to a boil.
  5. Let it simmer for two minutes, then remove from the heat and serve.
  6. Add the desired amount of Parmesan cheese to the soup, or sprinkle it directly onto the plate. ≈ 3 min
  7. In France, Gruyère cheese is typically used, but another type of mountain cheese from the same family – such as Conté du Jura or Savoie, or Valdostana fontina – also works very well, especially if you want to prepare the recipe in a more complete and refined way, by baking it. ≈ 3 min
  8. Toasted bread is essential and should be added to the mixture just before use.
