1. Prepare Oven and Crust:

• Preheat your oven to 425°F (220°C).
• Place your unbaked pie crust into a 9-inch pie plate (if not already in one). Crimp the edges as desired. Set aside.

2. Make the Cheesecake Layer:

• Ensure the cream cheese is fully softened to room temperature.
• In a medium bowl using an electric mixer (or by hand with vigor!), beat the softened cream cheese and 1/4 cup granulated sugar together until completely smooth and creamy.
• Beat in 1 large egg and the vanilla extract until just combined and smooth.

3. Assemble First Layers:

• Spread the prepared cheesecake mixture evenly into the bottom of the unbaked pie shell.
• Sprinkle the 1 cup of chopped pecans evenly over the top of the cheesecake layer.

4. Make the Pecan Pie Filling:

• In a separate medium bowl, whisk together the remaining 3 large eggs, the corn syrup, and the packed brown sugar until very well combined and smooth.

5. Add Top Layer and Bake:

• Carefully and slowly pour the pecan pie filling mixture evenly over the pecans and cheesecake layer in the pie shell. Try to ensure the pecans remain somewhat evenly distributed.
• Place the pie on a baking sheet (to catch potential drips). Bake in the preheated 425°F (220°C) oven for 10 minutes.
• Reduce Oven Temperature: After 10 minutes, reduce the oven temperature to 375°F (190°C).
• Continue baking for another 25-30 minutes. The pie is done when the filling appears mostly set (it should only have a slight jiggle in the very center) and the crust is golden brown. If the crust edges brown too quickly, you can shield them loosely with aluminum foil strips.

6. Cool Completely:

• Remove the pie from the oven and place it on a wire rack.
• Let the Pecan Cheesecake Pie cool completely to room temperature (at least 2-3 hours).
• For best results and easier slicing, chill the cooled pie in the refrigerator for several hours or overnight before serving.

7. Slice and Serve:

• Once fully cooled and preferably chilled, slice the pie into wedges using a sharp knife.
• Serve chilled or at cool room temperature. Enjoy this decadent combination!
