Leek Gruyere Quiche

Directions

Ingredients :

1 ½ cups all-purpose flour

5 tablespoons cold unsalted butter

1 large egg

1 pinch salt

1 tablespoon cold water

or as needed

1 tablespoon extra-virgin olive oil

2 leeks

white parts only

thinly sliced

4 eggs

9 ounces creme fraiche

¾ cup grated Gruyere cheese

½ cup grated Emmentaler cheese

⅓ cup cubed fully cooked ham

freshly ground white pepper

1 pinch ground nutmeg

Methods :

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.

Preheat the oven to 400 degrees F (200 degrees C). Grease a 10-inch springform pan.

Heat olive oil in a skillet and cook leeks over medium heat until translucent, about 5 minutes.

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.

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.

Bake in the preheated oven until filling is set, about 30 minutes.
