For the crust: In a bowl, whisk together flour and salt. Cut in the cold butter until the mixture resembles coarse crumbs. Press evenly into the bottom and up the sides of a 9-inch pie plate.
For the filling: In a large bowl, whisk the eggs and sugar until well combined. Gradually whisk in the flour until smooth.
Stir in the vanilla extract, milk, and melted butter. Fold in the chopped pecans.
Pour the filling into the prepared pie crust.
Bake in a preheated oven at 350°F (175°C) for 45-55 minutes, or until the center is set and the top is golden brown.
Let the pie cool completely on a wire rack before slicing and serving.
Notes
This pie is best served at room temperature or slightly chilled. It can be enjoyed on its own or with a dollop of whipped cream.
