The method

Step by step

  1. 1

    Preheat your oven to 190°C (375°F).

    About 10 min

  2. 2

    Unroll the pie crust and gently press it into a 9-inch pie dish. Trim any excess crust and crimp the edges decoratively.

    About 3 min

  3. 3

    Line the pie crust with parchment paper and fill with pie weights or dried beans. Bake for 15 minutes, then remove the weights and parchment and bake for another 5 minutes, until lightly golden.

    About 20 min

    Cook’s note: This step, called blind baking, prevents a soggy bottom crust.

  4. 4

    While the crust bakes, melt the butter in a medium skillet over medium-low heat.

    About 1 min

  5. 5

    Add the yellow onion to the skillet and cook slowly for 10-15 minutes, stirring occasionally, until deeply caramelized and tender.

    About 15 min

    Cook’s note: Cooking onions slowly brings out their natural sweetness.

  6. 6

    Remove the pie crust from the oven and reduce the oven temperature to 175°C (350°F).

  7. 7

    Sprinkle half of the gruyere cheese evenly over the bottom of the pre-baked pie crust.

    About 1 min

  8. 8

    Distribute the caramelized onion over the cheese, then top with the remaining gruyere cheese.

    About 1 min

  9. 9

    In a large bowl, whisk together the large eggs, heavy cream, milk, nutmeg, salt, and black pepper until well combined.

    About 2 min

  10. 10

    Carefully pour the egg mixture over the cheese and onions in the pie crust.

    About 1 min

    Cook’s note: Pour slowly to avoid disturbing the fillings.

  11. 11

    Bake for 30-35 minutes, or until the center is just set and the top is golden brown.

    About 35 min

    Cook’s note: A knife inserted near the center should come out clean.

  12. 12

    Remove the quiche from the oven and let it rest on a wire rack for at least 15 minutes before slicing and serving.

    About 15 min

    Cook’s note: Resting allows the custard to set completely, preventing it from collapsing when cut.

  13. 13

    Garnish with fresh chives before serving.
