How to make Classic French Onion Soup

  1. Step 1

    Peel the onions and slice them into thin rings.

  2. Step 2

    In a large saucepan, melt the butter and add the olive oil. Gently sauté the onions over medium heat.

  3. Step 3

    Season with salt and continue to cook the onions until they are golden brown.

  4. Step 4

    Sprinkle the flour over the onions and stir well, cooking for an additional 3 minutes.

  6. Step 6

    Season with ground black pepper and adjust salt to taste.

  7. Step 7

    In a separate pan, toast the slices of bread in a little olive oil until golden.

  8. Step 8

    Divide the soup into individual oven-safe bowls or ramekins. Place a slice of toasted bread on top of each serving and sprinkle with a bit of the grated cheese.

  9. Step 9

    Place the bowls under the broiler (grill) for a few moments, just until the cheese is melted and golden.

  10. Step 10

    Serve immediately while very hot.

Tips & Tricks

  1. Use sweet onions for a more delicate flavor.

  2. If you prefer a stronger cheese flavor, try Gruyère instead of Emmental.

  4. For a richer broth, use beef stock instead of vegetable broth.

  5. Keep an eye on the broiler to avoid burning the cheese topping.
