Prepare the Crust for Baking: Preheat your oven to 350°F (175°C). Place the unbaked pie crust into a 9-inch pie dish and set it on a baking sheet. Line the inside of the crust with parchment paper or foil, then fill it with pie weights (or dried beans/rice).
Blind Bake the Crust: Bake for 10 minutes. Carefully remove the crust from the oven and lift out the parchment and weights. Let the crust cool for a few minutes while you prepare the pumpkin filling.
Make the Pumpkin Filling: In a medium bowl, whisk together the pumpkin puree, eggs, evaporated milk, granulated sugar, brown sugar, cinnamon, nutmeg, ginger, cloves, and salt until smooth. Pour the pumpkin mixture into the prepared crust and bake for 25 minutes.
Make the Pecan Filling: While the pumpkin layer bakes, prepare the pecan topping. In another bowl, whisk together the corn syrup, brown sugar, eggs, melted butter, and vanilla until well blended. Stir in the pecans until evenly coated.
Add the Pecan Filling & Bake: Remove the pie from the oven after 25 minutes and carefully spoon the pecan mixture evenly over the partially baked pumpkin layer. Return the pie to the oven and bake for an additional 30 - 40 minutes, or until the topping is set and slightly caramelized.
Cool The Pie: Allow the pie to cool completely at room temperature for at least 3 hours before slicing to ensure the filling sets properly.
