Remove pie crust from refrigerator, divide into two halves and roll out bottom crust on top of a sheet of baking parchment or waxed paper lightly dusted with flour to keep it from sticking. Using a rolling pin, roll the dough out from the center, rotating the paper to distribute it evenly. Lay pie pan lightly upside down on crust to check size (dough should be about 11″ in diameter, or show a 1″ margin all around the pan). When dough is big enough, center pie pan on crust and invert dough into the pan.
