To keep its shape, use pie weights and bake it hot and fast.


Blind baking is baking an unfilled
pie shell to produce a partially- or fully-baked
crust. Blind baking
the crust prevents the crust from becoming soggy from
custard based
fillings, and is necessary for pies which have the fillings either
cooked separately or not at all.
To blind bake a crust, once your crust is prepared and placed in your
pie pan, prick a few holes (this is called "docking") or fill it with pie weights (do
one or the other, if you fill it with weights, you don't need to dock), and
bake until browned (or just for several minutes if your goal is a
partially-baked crust). To fully blind bake, bake it at 425 degrees 15 to 18 minutes or until
the sides begin to
brown. (The initial high heat will force much of the steam
out, helping the crust become flaky.)
Remove the pan from the oven. Gently remove your pie weights. Reduce oven to 375 degrees
and continue to bake the crust for several minutes until it's golden.
Without the weight of a filling, a baking crust can shrink, fill with
air pockets, and puff up with bubbles, so it is important to either dock
the crust or weigh the
crust down as it bakes. Weights are easier and you won't risk the
filling leaking through the holes. This is done by lining the dough with parchment
paper or foil (if you use foil, you may need to grease the dough first,
to prevent the foil from sticking) and filling it with pie weights or a
pie chain (or dried beans, pennies,
rice, marbles, etc.) to hold its shape during baking. [TIP: Keep your
weights in an oven cooking bag. You can just place the bag with the
weights in the pie crust, then lift the whole bag out to store for next
time.] Alternatively, you can set a perforated pie pan into the crust.

You may want to moisture-proof your crust when blink baking by removing
the crust from the oven when it has about 5 minutes left to bake and
applying your egg wash with a
pastry brush on the bottom of the crust
and about an inch up the sides. Then resume baking the crust for the
remaining 5 minutes.
