16 ingredients
6 steps

Ingredients

  • Crust:
  • 1 1/2 cups all-purpose flour
  • 5 tablespoons cold unsalted butter
  • 1 large egg
  • 1 pinch salt
  • 1 tablespoon cold water, or as needed
  • Filling:
  • 1 tablespoon extra-virgin olive oil
  • 2 leeks, white parts only, thinly sliced
  • 4 eggs
  • 9 ounces creme fraiche
  • 3/4 cup grated Gruyere cheese
  • 1/2 cup grated Emmentaler cheese
  • 1/3 cup cubed fully cooked ham
  • freshly ground white pepper
  • 1 pinch ground nutmeg

Directions

  1. 1
    Combine flour, butter, 1 egg, and salt in a bowl. Knead together with your hands, adding as much water as needed, in small amounts, to create a smooth dough. Shape dough into a ball, flatten, and wrap in plastic wrap. Refrigerate for at least 30 minutes.
  2. 2
    Preheat the oven to 400 degrees F (200 degrees C). Grease a 10-inch springform pan.
  3. 3
    Heat olive oil in a skillet and cook leeks over medium heat until translucent, about 5 minutes.
  4. 4
    Remove dough from fridge. Dust a work surface with flour and roll out dough into a circle about 1 inch larger than the springform pan. Fold carefully in half, lift up, and unfold over the pan. Press over the bottom and 1 inch up the sides.
  5. 5
    Whisk 4 eggs and creme fraiche in a bowl. Stir in leeks, Gruyere cheese, Emmentaler cheese, and ham. Season with white pepper and nutmeg. Pour over the crust and spread evenly with the back of a spoon.
  6. 6
    Bake in the preheated oven until filling is set, about 30 minutes.
