🍲 Basler Mehlsuppe (Basel flour soup)
Basler Mehlsuppe is a dark, savoury soup made by slowly toasting flour in butter until it turns deep brown, then simmering it with onion and beef broth. The result is smooth, rich and nutty, with a roasted flavour. It is served piping hot with grated Gruyère cheese scattered over the top, which melts into the soup.

Recipe
Ingredients
- 60 g plain flour
- 40 g butter
- 1 onion, finely chopped
- 1.2 litres beef broth
- 1 bay leaf and a pinch of grated nutmeg
- 60 g Gruyère, grated
- Salt and black pepper
Method
- Toast the flour in a dry, heavy pan over medium-low heat, stirring constantly, for 15–20 minutes until it is the colour of cinnamon. Let it cool slightly.
- Melt the butter in a pot, soften the onion for 5 minutes, then stir in the toasted flour.
- Whisk in the broth a little at a time to avoid lumps, add the bay leaf, and simmer gently for 30–40 minutes, stirring now and then.
- Season with salt, pepper and nutmeg, remove the bay leaf and serve hot with the Gruyère sprinkled on top.
How to make it lighter
- Use half the butter: the toasted flour already gives a deep flavour.
- Cheese adds up quickly — a tablespoon of grated Gruyère per bowl is enough for taste.
- Choose a fat-skimmed or low-salt beef broth and serve with a green salad for a light supper.
History
The soup is famously linked to Basel Fasnacht, the city's carnival, which opens with the Morgestraich at 4 a.m.; afterwards revellers warm up with bowls of Mehlsuppe in restaurants across the old town. Simple flour soups were once everyday fare in many parts of Switzerland and southern Germany.
