Custard Quiche

For a standard 9-inch quiche, you should use 3 to 4 large eggs. The secret to a perfect, silky custard texture lies in the ratio. According to The Kitchen, the golden ratio is 1 large egg to 1/2 cup of dairy. Using too many eggs will make the quiche rubbery and omelet-like. Conversely, adding too much dairy prevents the custard from setting properly.

Custom-Style Customizable Quiche

This master recipe utilizes the time-tested 4-egg custard base. It yields a perfectly rich, velvety slice that holds its shape beautifully.

The Custard Base

  • 4 large eggs
  • 1 cup heavy cream (for premium richness)
  • 1/2 cup whole milk
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon freshly ground black pepper
  • 1 pinch (1/8 tsp.)ground nutmeg (optional, but adds authentic French warmth)

The Structure & Fillings

  • 1 unbaked 9-inch pie crust (deep dish is preferred)
  • 1 cup shredded cheese (such as Gruyère, sharp Cheddar, or Swiss)
  • 1 cup cooked add-ins (e.g., crumbled bacon, chopped ham, sautéed spinach, or onions)

Instructions

  1. Blind-Bake the Crust
  • Preheat your oven to 350°F (175°C).
  • Roll out your dough into a 9-inch pie plate and crimp the edges.
  • Line the inside with parchment paper and fill it with pie weights, dried beans, or raw rice.
  • Bake for 20 minutes. Remove the weights and paper, then bake for another 6 to 8 minutes until the base looks dry and lightly golden.
  1. Prep the Custard & Fillings
  • Whisk the eggs, heavy cream, milk, salt, pepper, and nutmeg together in a medium bowl until thoroughly combined and slightly frothy. Pro tip: Do not over-beat the eggs, as this makes the custard rubbery rather than silky
  • Ensure your chosen add-ins (like mushrooms or spinach) are fully cooked and squeezed completely dry. Wet ingredients will ruin the custard.
  1. Layer and Assemble

Lower your oven temperature to 350°F

  • Scatter half of your shredded cheese across the bottom of the warm, blind-baked pie crust.
  • Spread your cooked mix-ins evenly over the cheese layer.
  • Pour the egg and dairy mixture slowly over the top.
  • Sprinkle the remaining cheese over the surface.
  1. Bake and Set
  • Place the quiche on a rimmed baking sheet.
  • Bake on the middle rack for 40 to 50 minutes. The edges should be golden brown, but the very center should still jiggle slightly when nudged.
  • Cool on a wire rack for at least 20 minutes before slicing. The filling will finish firming up as it cools.
