World Kitchen France: Onion Soup

This month, we’re luxuriating in the deliciously pungent aromas of the French nation’s favourite bistro classic: onion soup. A perfect marriage of silky onions, rich, savoury broth, crunchy toasted bread and layers of gooey cheese, this French national treasure will really hit the spot on a cold winter evening.

1 Melt the butter in a large pan on a medium-low heat. Add the onions, turn down the heat and leave them to cook until they take on a deep, golden-brown colour, stirring regularly.

2 Season with salt and pepper and keep browning the onions for at least an hour on a low heat, stirring occasionally.

3 Pick the leaves from the thyme and add them to the onions along with the flour and cook for another 2–3 minutes.
