Ingredients
Method
- Roll the pastry on a floured surface to an 11-inch circle, fit into a 9-inch pie plate, trim, fold, and crimp the edge. Chill if soft.
- Sauté bacon in a skillet over medium heat until crisp, about 6 to 8 minutes; drain and set aside. Cook the leeks in the same pan until soft and golden, about 5 minutes. Let cool slightly.
- Whisk eggs, heavy cream, salt, pepper, and nutmeg until smooth. Scatter bacon, leeks, and Gruyère in the pastry shell, then pour the custard over the top.
- Bake on the middle rack at 400°F (200°C) for 25 to 30 minutes, until the crust is golden and puffed and the center jiggles just slightly.
- Cool on a rack for 10 minutes, then slice and serve warm.
Notes
The quiche will puff dramatically in the oven and settle as it cools, which is normal. If your oven runs hot, check at 22 minutes and tent the edges with foil if the crust browns too fast. For a vegetarian version, replace the bacon with sautéed mushrooms and use a good vegetable broth deglaze instead of drippings, though the custard base stays the same.
