Print Recipe

A comforting and flavorful quiche featuring sweet caramelized onions and nutty Gruyere cheese baked in a flaky crust. Perfect for brunch, potlucks, or cozy meals.

Ingredients

Scale
  • 1 unbaked 9-inch pie crust (store-bought or homemade)
  • 2 large yellow onions, thinly sliced
  • 2 tablespoons unsalted butter
  • 1 ½ cups shredded Gruyere cheese (about 150 g)
  • 4 large eggs, room temperature
  • 1 cup heavy cream (240 ml)
  • ½ cup whole milk (120 ml)
  • 1 teaspoon Dijon mustard
  • 1 teaspoon salt, or to taste
  • ½ teaspoon freshly ground black pepper
  • 1 teaspoon fresh thyme, finely chopped (optional)

Instructions

  1. Heat 2 tablespoons of unsalted butter over medium-low heat in a large skillet. Add the thinly sliced yellow onions and a pinch of salt. Cook slowly, stirring occasionally, until onions are golden brown and caramelized, about 30-40 minutes. Add a splash of water if onions start to stick.
  2. Preheat oven to 375°F (190°C).
  3. Roll out the pie crust into a 9-inch pie dish. Prick the bottom with a fork. Line with parchment paper and fill with pie weights or dried beans. Bake for 15 minutes, then remove parchment and weights and bake another 5-7 minutes until lightly golden.
  4. In a medium bowl, whisk together 4 large eggs, 1 cup heavy cream, ½ cup whole milk, 1 teaspoon Dijon mustard, 1 teaspoon salt, and ½ teaspoon freshly ground black pepper until smooth and slightly frothy.
  5. Spread the caramelized onions evenly over the pre-baked crust. Sprinkle shredded Gruyere cheese on top, followed by fresh thyme if using. Pour the custard mixture gently over the filling.
  6. Bake the quiche for 35-40 minutes until the filling is set but still slightly jiggly in the center and the top is lightly golden. Cover loosely with foil if browning too quickly.
  7. Let the quiche cool for at least 15 minutes on a wire rack before slicing. Serve warm or at room temperature.

Notes

Caramelize onions slowly over low heat for best flavor. Blind bake the crust to prevent sogginess. Use room temperature eggs to avoid curdling. The quiche should have a slight wobble when done and will firm up as it cools. For gluten-free, use almond flour crust; for dairy-free, substitute dairy ingredients accordingly.
