Common Quiche Questions
What is the difference between quiche and frittata?
Quiche is baked in a crust and uses a richer custard, usually with cream or milk. A frittata is usually crustless and is often started on the stovetop and finished in the oven (though some are fully oven-baked). Quiche is creamier and more "sliceable" once cooled.
How do I know when quiche is done?
The center should be just set. Give the pan a gentle nudge. The edges should look set and the middle can wobble slightly like gelatin. If it sloshes like liquid, it needs more time.
If you want a more concrete check, aim for 170 to 175°F in the center, or insert a knife about 1 inch from the center. It should come out mostly clean (a little moisture is fine, raw egg is not).
Why did my quiche come out watery?
Usually it is from vegetables releasing moisture or from underbaking. Cook watery veggies first (mushrooms, spinach, zucchini), cool them, then add. Also let the quiche rest 15 to 20 minutes before slicing so the custard sets.
Can I make quiche without heavy cream?
Yes. You can use half-and-half, whole milk, or a mix of milk and sour cream or Greek yogurt. The richer the dairy, the silkier the texture. If using all milk, expect a slightly lighter custard.
Do I have to pre-bake the crust?
I strongly recommend it. Even 10 to 12 minutes helps prevent a soggy bottom. If you skip it, bake on the lower rack and expect a softer crust.
Can I make it ahead?
Absolutely. Quiche is often better after it has had time to cool and set. Bake it up to 1 day ahead, refrigerate, then rewarm at 325°F until heated through.
