This classic French soup will surprise you with its sweet smell of cooked onions and melted cheese, having nothing to do with the pungent odor of raw onions!
This soup was once considered the food of the poor, since onion, stale bread and chicken stock are all chep ingredients. You can even replace the chicken broth with water.
The onion soup was already a popular dish since Roman times. Then and now, onions were a low-cost ingredient and easy to grow.
What you need
For four servings :
- Chicken stock
- 5 big onions
- Olive oil
- A few spoons of flour
- Peel 5 large onions and cut them into thin slices.
- In a large saucepan or casserole put a bit of butter and 2 tablespoons of olive oil. Add the sliced onions. Make them sweat without browning.
- Add a spoonful of flour and cook for a few more minutes while stirring.
- Sprinkle with the chicken stock or water.
Add salt to taste.
You can choose between two different cooking methods:
Leave to cook for about 20 min. Serve the onion soup hot and cover each portion with bread croutons and grated cheese such as Emmenthal or Gruyère.
Turn the oven on to 200 °C. Take four oven bowls and put in each one alternatively 2-3 slices of bread and grated cheese 2-3 times, then add the onion soup. Cook 15 minutes and serve hot.
In both cases it will taste delicious. Bon appétit !
