Baking blind means to partially or completely bake a pie crust before it’s filled.
To prebake an unfilled pie crust, first prick it all over with a fork. Then line the crust with parchment paper or foil and fill it with pie weights, raw rice or dried beans.
This helps prevent the crust from shrinking or puffing up during baking.
Bake the crust at 375ºF (190ºC) for 8 - 10 minutes.
Remove the pan from the oven and carefully remove the parchment paper and pie weights. Prick the crust again, if necessary.
Continue baking for another 6 - 7 minutes or until pastry is set and golden brown around edges
