How to make
Peel and cut the onion into crescents. Season with salt and rub by hand.
Heat 1/2 cup of olive oil in a pot. Add the onion and fry briefly.
Pour the white wine, wait a few minutes for the alcohol to evaporate and sprinkle with a tablespoon of flour. Stir.
Pour the vegetable broth, add the cream and season with a generous pinch of nutmeg. Cover the pot and cook for 25 minutes. Toast slices of stale bread. Distribute the soup into bowls.
Place a slice of toast on top and sprinkle generously with the grated cheese.
Bake the onion soup in a preheated oven at 390°F (200°C) for about 5-6 minutes. Serve it immediately!
Enjoy!
