You might be tempted to skip this step. You might think, “I’m in a hurry, and the filling will just cook it anyway.” Let me stop you right there. That is how you get a doughy, sad mess. The liquid custard will seep into the raw dough and turn it into paste. It’s a tragedy, and we’re here to prevent it.
Blind baking (that’s the fancy French term for pre-baking a crust) does two things. First, it sets the structure so the crust doesn’t shrink into a weird, puckered shape. Second, it evaporates moisture, creating a barrier that repels the wet filling. It’s basically magic, but with butter.
Tools of the Trade (You Don’t Need Much)
The only special tool you really need is parchment paper or aluminum foil. You’ll also need something heavy to weigh down the dough while it bakes—this is called “pie weights.” If you don’t have fancy ceramic beads, grab a bag of dried beans or some dry rice. I once used a handful of old pennies wrapped in foil. Desperate times.
Do not skip the weights. Without them, the sides of your crust will slump down like a deflated soufflé. We want a tall, proud crust, not a shallow bowl. Your quiche deserves a nice, deep home.
