Soupe à l'oignon gratinée
the onion soup of Les Halles, with caramelised onions, stock, toasted bread and cheese browned under the grill
preparation
How it is made
Quantities are for 6 people. The steps are in the order you do them.
- peel the onions, slice them and let them turn golden in the butter in a saucepan
- when they start to colour add two tablespoons of water, so that they do not burn, and leave them over a gentle heat until they just caramelise: they are what gives the stock its colour
- add the flour, which gives a little body, deglaze with the white wine and pour in the stock
- bring to a gentle boil and leave to cook for about twenty minutes; season with salt and pepper
- toast the slices of bread and place them in the bottom of a cocotte that can go in the oven
- pour in the soup: the bread floats back up, and you cover it with the grated cheese
- put the cocotte under the oven grill until the top is well browned
