If using a store-bought crust, thaw it according to package directions. Place it in a 9-inch pie dish and crimp the edges.

In a large mixing bowl, whisk together sweetened condensed milk, eggs, brown sugar, melted butter, vanilla extract, and salt until smooth and fully combined.

Stir in the pecan halves until they are well coated with the filling mixture.

Pour the pecan filling into the prepared pie crust. Spread the pecans evenly.

Bake in a preheated 350°F (175°C) oven for 45–50 minutes, or until the center is set and the top is golden brown.

Let the pie cool completely at room temperature before slicing. It will set more as it cools.

Serve as-is, or with a dollop of whipped cream or a scoop of vanilla ice cream.
