Wrap dough around rolling pin, and gently fit inside a 15- x 10-inch jelly-roll pan. Turn dough edges under; crimp. Prick bottom and sides of dough with a fork. Line with parchment paper, leaving a 3- to 4-inch overhang around edges of pan. Fill with pie weights or dried beans. Bake 10 minutes. Remove parchment and pie weights. Return crust to oven; bake at 375°F for 5 minutes. Transfer to a wire rack; cool completely, about 30 minutes.
