Preheat oven to 350°F (175°C). Place unbaked pie crust in a 9-inch pie dish and crimp edges as desired.
In a large bowl, whisk together pumpkin puree, corn syrup, brown sugar, granulated sugar, eggs, melted butter, vanilla, cinnamon, ginger, nutmeg, and salt until smooth.
Pour the pumpkin mixture into the prepared pie crust. Arrange pecan halves evenly over the top, pressing them slightly into the filling.
Bake for 50–60 minutes, or until the filling is set and a knife inserted near the center comes out clean. The pecans should be lightly toasted.
Remove from oven and let cool completely on a wire rack, about 2 hours, before slicing and serving.
Notes
Serve with whipped cream or vanilla ice cream for an extra indulgent treat. Store leftovers covered in the refrigerator for up to 4 days.
