Ingredients

Scale
  • 1 pre-made 9-inch (23 cm) pie crust, refrigerated or homemade
  • 6 slices thick-cut bacon, diced
  • 2 large yellow onions, thinly sliced
  • 1 ½ cups (about 150 g) shredded Swiss cheese (Gruyère or Emmental)
  • 4 large eggs at room temperature
  • 1 cup (240 ml) heavy cream
  • ½ cup (120 ml) whole milk
  • 1 teaspoon kosher salt
  • ½ teaspoon freshly ground black pepper
  • 1 teaspoon fresh thyme leaves, chopped (optional)
  • 1 tablespoon unsalted butter

Instructions

  1. Preheat your oven to 375°F (190°C) and allow the pie crust to come to room temperature if refrigerated.
  2. Heat 1 tablespoon of unsalted butter in a large skillet over medium-low heat. Add the thinly sliced yellow onions and a pinch of salt. Stir occasionally and cook slowly for about 25-30 minutes until onions are deeply golden and caramelized. Add a splash of water if they start sticking.
  3. In another skillet, cook the diced bacon over medium heat until crispy, about 6-8 minutes. Drain on paper towels to remove excess grease.
  4. In a bowl, mix the shredded Swiss cheese with the cooked bacon pieces.
  5. In a large mixing bowl, whisk together 4 large eggs, 1 cup heavy cream, ½ cup whole milk, 1 teaspoon kosher salt, ½ teaspoon black pepper, and 1 teaspoon fresh thyme leaves until well combined and slightly frothy.
  6. Roll out your pie crust into the 9-inch pie dish. Spread the caramelized onions evenly across the bottom, then sprinkle the bacon and cheese mixture over the onions. Pour the egg and cream custard over the fillings, filling the crust almost to the top but not spilling over.
  7. Place the quiche on the middle rack in the preheated oven. Bake for 35-40 minutes or until the custard is set and the top is lightly golden (a knife inserted should come out clean). Cover crust edges with foil halfway through baking if they brown too quickly.
  8. Let the quiche cool for at least 10 minutes before slicing to help it set further and make cleaner slices.

Notes

Caramelize onions slowly over low heat to avoid burning and develop sweetness. Drain bacon well to prevent greasiness. Use fresh-grated Swiss cheese for better melt and texture. Optionally blind bake crust for 8-10 minutes to avoid sogginess. Room temperature eggs and cream help create a smooth custard. Cover crust edges with foil if browning too fast.
