Summary
The soupe à l'oignon of Parisian bistros: onions caramelised very slowly, beef stock and white wine, topped with bread and cheese and grilled until bubbling. Humble, comforting and perfect for cold nights.
Ingredients
- 1 tablespoon Wheat flour
- 50 g Butter
- 1 tablespoon Olive oil
- 1 kg Onion (thinly sliced)
- Salt (to taste)
- Black pepper (freshly ground)
- 2 sprigs Thyme
- 1 leaf Bay Leaf
- 1.2 l Beef Stock (homemade or good quality)
- 150 ml Dry White Wine
- 150 g Gruyère (grated)
- 8 slices Baguette (a day old)
Instructions
Melt the butter with the oil in a large heavy-based pan. Add the onions with a pinch of salt, stir to coat and cook covered over medium-low heat until soft and they have released their liquid.
15 min
Uncover and keep cooking over medium-low heat, stirring every few minutes and scraping the bottom, until the onions are greatly reduced and a deep mahogany colour. If they catch, add a spoonful of water and scrape the bottom clean.
45 min
Sprinkle over the flour and stir for two minutes. Pour in the wine, let it bubble until almost completely evaporated, then add the stock, thyme and bay leaf.
5 min
Simmer the soup gently, half covered. Remove the herbs, taste and adjust the salt and pepper.
25 min
Meanwhile, toast the bread slices in the oven until dry and crisp. Turn on the grill.
Ladle the soup into ovenproof bowls, top with one or two slices of bread and cover generously with cheese. Grill until the cheese bubbles and browns at the edges, and serve at once, taking care as the bowls will be very hot.

Notes
All the flavour comes from the onions, so don't rush them: they should go from white to golden and then to a deep mahogany, stirred often, with the heat lowered if they catch. There's no need to add sugar. Gruyère is the usual cheese, though Comté or Emmental work too. Without the topping, the soup keeps for three days in the fridge and freezes well; grill the portions just before serving. For a vegetarian version, use a good dark vegetable stock.
