Place the pie crust in a 9-inch pie pan and crimp the edges as desired.
In a large mixing bowl, whisk together the eggs, corn syrup, brown sugar, melted butter, vanilla extract, and salt until well combined.
Stir in the butterscotch chips and chopped pecans.
Pour the filling into the prepared pie crust and spread it evenly.
Bake for 50–60 minutes, until the edges are set and the center is slightly jiggly. Cover the crust edges with aluminum foil if they begin to brown too quickly.
Remove the pie from the oven and let it cool completely before slicing and serving.
Notes
Refrigerate the leftovers, covered for up to 4 days.
