If using a frozen pie crust, take it out of the freezer now.
Preheat an oven to 375°F.
Mix corn syrup and brown sugar in a medium saucepan and cook over medium-low heat until the brown sugar has melted [about 5 to 10 minutes].
Remove from heat and allow the mixture to cool for at least 10 minutes.
While mixture is cooling, mix eggs and pecans in a separate bowl.
After sugar mixture has cooled, add butter and vanilla. Stir until butter is melted.
Pour sugar mixture in the bowl with pecans and eggs. Mix well.
Place pie crust on a baking sheet and fill with the pecan pie filling.
Place into preheated 375 Degree F oven and cook for 30 minutes, checking crust color at 20 minutes. If crust or pecans are browning too quickly, loosely cover pie with foil and continue baking.
After 30 minutes, reduce oven heat to 350 Degrees F.
Bake pie for an additional 15 minutes.
Pie is done when the center of the pie filling reads 200°F on a thermometer.
Remove pie from oven and allow to cool for a minimum of 2 hours before slicing.
Notes
Pie requires 2 hours of cooling time in addition to cook time listed. Please plan accordingly.Dark corn syrup can be substituted with light corn syrup and light brown sugar can be substituted with dark brown sugar. All the different combinations create different flavors.
