(optional) sweetened whipped cream and berries for topping
Instructions
Preheat oven to 425° F. On a lightly floured surface, roll dough to fit a 9-inch pie plate. Crimp edge of crust. Line unpricked crust with a double thickness of foil. Fill with pie weights, dried beans or uncooked rice.
Place on a baking sheet; bake until edge is light golden brown, 8 minutes. Remove foil and weights; bake until bottom is golden brown, 6 minutes longer. Cool. Reduce oven setting to 350° F.
In a large bowl, beat butter and sugar until blended. Add eggs, 1 at a time, beating well after each addition. Beat in flour and salt. Gradually stir in buttermilk, lemon juice, lemon zest, and vanilla.
Pour filling on top. Bake until center is set, 45-55 minutes. Cover top loosely with foil during the last 15 minutes if crust is browning too much.
Cool completely on a wire rack. Great served chilled with whipped cream and berries. Refrigerate leftovers.
