Preheat the oven to 350℉/175℃.
Unroll the pie crust, and cover the bottom of a 9-inch pie plate. Trim the edge, leaving a ½-inch overhang. Fold the overhang under and lightly press against the rim of the pie plate, then crimp decoratively.
Lightly prick the bottom all over with a fork. Chill until firm, at least 30 minutes (or freeze for 10 minutes).
Heat a deep, large skillet over medium heat, and add butter, granulated sugar, and brown sugar. Quickly stir to combine the butter and sugar. Then whisk in corn syrup and salt.
Lightly beat the eggs in a medium bowl (do not overbeat). Then whisk in the corn syrup mixture.
Place pecans over the crust on the bottom of the pie pan, and pour the corn syrup mixture evenly over the pecans.
Place on a baking sheet and bake for a total of 50 minutes to an hour. Cover the crust with foil or a pie crust shield for the first 30 minutes to prevent the edges from browning too soon. That would also be the perfect time to add decorative pecans if desired. Continue baking for the remainder of the time or until the pie is set.
Remove from the oven, and cool completely before serving. It can take 3-4 hours.
Serve pecan pie warm or at room temperature with whipped cream or vanilla ice cream.
