A comforting and flavorful quiche featuring smoky bacon, sweet caramelized onions, and fresh thyme in a flaky buttery crust. Perfect for brunch or a no-fuss weeknight dinner.

Ingredients

Scale
  • 1 store-bought 9-inch (23 cm) pie crust or homemade (butter-based for best flavor)
  • 6 slices thick-cut bacon, chopped
  • 2 large yellow onions, thinly sliced
  • 2 teaspoons fresh thyme leaves, chopped
  • 4 large eggs, room temperature
  • 1 cup (240 ml) heavy cream
  • ½ cup (120 ml) whole milk
  • Salt and pepper to taste
  • 1 cup (100 g) shredded Gruyère cheese (optional but highly recommended)

Instructions

  1. Preheat oven to 375°F (190°C). Roll out the pie crust into a 9-inch quiche pan. Prick the bottom with a fork a few times. Line with parchment paper or foil and fill with pie weights or dried beans. Blind bake for 15 minutes to prevent sogginess.
  2. While the crust bakes, heat 1 tablespoon olive oil or butter in a large skillet over medium-low heat. Add thinly sliced onions with a pinch of salt. Cook slowly, stirring occasionally, for 25-30 minutes until soft, golden, and caramelized.
  3. In a separate pan, cook chopped bacon over medium heat until crisp, about 8 minutes. Drain on paper towels to remove excess fat.
  4. In a mixing bowl, whisk together eggs, heavy cream, milk, about ½ teaspoon salt, and ¼ teaspoon freshly ground black pepper. Stir in fresh thyme leaves and shredded Gruyère cheese if using.
  5. Remove pie crust from oven and discard weights and parchment. Layer caramelized onions evenly over crust, then add crispy bacon. Pour custard mixture on top and gently tap pan to release air bubbles.
  6. Bake quiche at 375°F (190°C) for 35-40 minutes, until custard is set but slightly wobbly in center and top is golden and puffed.
  7. Let quiche cool for 10-15 minutes before slicing to allow custard to firm up.

Notes

Blind baking the crust is essential to prevent sogginess. Caramelize onions slowly over low heat for best flavor. Drain bacon fat well to avoid greasy filling. Use room temperature eggs and dairy for even custard cooking. Cover crust edges with foil if browning too fast. Lower oven temperature by 10°F if custard bubbles excessively.
