Vegetable Quiche with Crisp Crust
A reliable quiche is less about a specific set of ingredients and more about the architecture of the custard. When you balance the moisture of your vegetables with a slow-cooked egg base, you get a slice that stands upright and holds its texture.
Control the moisture, control the result.
Your biggest enemy is water. If your vegetables aren't thoroughly dried after cooking, the custard will break and turn grainy.

What goes in.
- 1 discchilled pie dough
- 4 largeeggs
- 1.5 cupsheavy cream
- 1 cupleeks, white parts only, thinly sliced
- 1 cupbaby spinach, wilted and squeezed dry
- 1/2 cupgruyère cheese, grated
- 1/2 tspkosher salt
- 1/4 tspblack pepper
Setting the foundation
Lining the dough with parchment and weights during the first bake prevents the crust from shrinking or bubbling, creating a seal that keeps the liquid custard from soaking through.
The method.
Prepare the crust
Roll out your dough, fit it into the pie dish, and chill it for 30 minutes. Line it with parchment and weights, then bake at 375°F for 20 minutes.
Cook the fillings
Sauté the leeks in butter until soft. Add the spinach, stir for one minute, then transfer to a paper towel to remove every drop of excess moisture.
Whisk the custard
Whisk eggs, cream, salt, and pepper in a bowl until the mixture is uniform and no streaks of egg white remain.
Assemble and bake
Scatter the vegetables and cheese into the crust. Pour the egg mixture over the top until it reaches just below the rim. Bake at 350°F until the center is set but still wobbles slightly, about 35 to 40 minutes.
Other turns to take.
Roasted Pepper and Goat Cheese
Replace leeks with jarred roasted red peppers and fold in crumbles of goat cheese before pouring the custard.
Mushroom and Thyme
Sauté sliced cremini mushrooms until they turn deep brown and dry before adding them to the base.
When it doesn't go to plan.
Always let the quiche rest for at least 20 minutes before slicing; this allows the proteins to finish setting.
If your crust starts browning too quickly, cover the edges with a foil ring.
Use a fine grater for the cheese so it melts into the custard rather than sinking to the bottom.
The ones that keep coming up.
Why did my quiche turn out watery?
The vegetables likely released moisture into the custard. Ensure you sauté them thoroughly and squeeze out any liquid before adding them to the crust.
Can I use milk instead of cream?
You can, but the texture will be less stable and more likely to curdle. Stick to higher fat dairy for a clean, set slice.
