🛒 Ingredients

10 servings

10
  • 1 large onion, finely chopped
  • 2 tablespoons unsalted butter
  • ⅓ cup (40 g) all-purpose flour
  • 1 cup (250 ml) whole milk
  • 1 cup (150 g) fresh spinach, sautéed in olive oil and drained
  • 4 eggs, whites and yolks separated
  • Salt and freshly ground black pepper to taste
  • Fresh flat-leaf parsley and chives, finely chopped
  • 1 cup (100 g) gruyère or mature cheddar, grated
  • ¾ cup (200 ml) heavy cream

Directions

  1. 1

    Melt the butter in a heavy-bottomed saucepan and sauté the onion over medium heat until golden and soft.

  2. 2

    Add the flour and cook for 3 minutes over low heat, stirring constantly to build a smooth roux with no raw flour taste.

  3. 3

    Remove from heat and whisk in the milk gradually until fully incorporated and lump-free.

  4. 4

    Return to low heat and stir continuously until the béchamel thickens. Off the heat, fold in the spinach, egg yolks one at a time, fresh herbs, seasoning, and heavy cream.

  5. 5

    Whip the egg whites to stiff peaks. Using a spatula, gently fold them into the mixture in three additions with slow upward strokes to preserve all the air.

  6. 6

    Pour into a buttered baking dish, cover generously with grated cheese, and bake at 400 °F (200 °C) for 25–30 minutes until puffed and deeply golden.

💡 Chef's Tip

Fold the egg whites gently and in stages — this is what creates the soufflé's signature lift. Serve straight from the oven as it deflates within minutes!
