Vegetable Quiche
A reliable quiche is a masterclass in managing moisture. By cooking the onions, peppers, and greens until they are dry in the pan, you prevent the liquid from compromising the crispness of the pastry base.
Control the moisture at every step.
If the vegetables are wet, the quiche will be mushy. Always pat your cooked vegetables dry with a paper towel before adding them to the egg mixture.

What goes in.
- 1pre-made or homemade pastry dough
- 3large eggs
- 1 1/2 cupsheavy cream
- 1 cupleeks, white and light green parts, sliced thin
- 2 cupsfresh spinach, stemmed and chopped
- 1/2 cupgruyère cheese, grated
- 1 tbspunsalted butter
- 1/2 tspsea salt
- 1/4 tspfreshly cracked black pepper
Set the foundation
Line your chilled crust with parchment and fill it completely with pie weights. Bake until the edges are pale gold; only then do you remove the weights to finish the base, ensuring it stays crisp under the wet custard.
The method.
Prepare the crust
Roll out your dough, press it into the pie dish, and chill it for 20 minutes before lining it with parchment and weights.
Blind bake
Bake at 375°F (190°C) for 20 minutes with weights. Remove weights and parchment, then bake for another 8 minutes until the bottom looks set and matte.
Sauté the vegetables
Melt butter in the skillet over medium heat. Cook leeks until soft, add spinach, and sauté until all moisture has evaporated. Remove from heat and drain on paper towels.
Assemble
Whisk eggs, cream, salt, and pepper in a bowl. Scatter the sautéed vegetables and cheese into the blind-baked shell. Pour the custard over the top.
Bake
Place the dish on a rimmed baking sheet. Bake at 350°F (175°C) for 35 to 40 minutes. The center should wobble slightly like gelatin but not slosh.
Rest
Allow the quiche to sit on a wire rack for at least 20 minutes before slicing. This allows the custard to firm up fully.
Other turns to take.
Roasted Vegetable
Substitute leeks for roasted cherry tomatoes and zucchini, ensuring they are drained of excess oil before adding to the shell.
Herb-Forward
Fold a tablespoon of finely minced fresh chives or tarragon into the custard mixture for a sharper profile.
When it doesn't go to plan.
Use a rimmed baking sheet under your pie dish to catch any accidental drips in the oven.
If the crust edges start browning too quickly, shield them with strips of aluminum foil.
Grate your own cheese rather than using pre-shredded to ensure it melts smoothly into the custard.
The ones that keep coming up.
Why did my quiche turn out watery?
The vegetables likely released water into the custard. Ensure you sauté them until the skillet is dry before assembly.
Can I substitute milk for heavy cream?
You can, but the final texture will be less firm and more prone to weeping. Cream provides the necessary fat to set into a cohesive structure.
