Preheat oven to 375°. On a lightly floured surface, roll dough to a 1/8-in.-thick circle; transfer to a 9-in. pie plate. Trim crust to 1/2 in. beyond rim of plate; flute edge. Refrigerate while preparing filling.
In a bowl, whisk eggs and sugar until smooth. Add maple syrup, butter, vanilla, salt and pecans. Pour into crust.
Bake until a knife inserted in the center comes out clean, 30-40 minutes. Cool on a wire rack for 1 hour. If desired, top with whipped cream to serve. Store in the refrigerator.
Combine 1-1/4 cups all-purpose flour and 1/4 tsp. salt; cut in 1/2 cup cold butter until crumbly. Gradually add 3-5 Tbsp. ice water, tossing with a fork until dough holds together when pressed. Shape into a disk; wrap and refrigerate 1 hour.
