Preheat oven to 425°F.
Place the unbaked pie crust into a 9-inch pie dish.
In a large bowl, whisk the pumpkin puree until smooth.
Add the eggs and whisk until combined.
Add the granulated sugar and brown sugar and whisk.
Add the cinnamon, ginger, nutmeg, and salt.
Whisk until the spices are evenly blended.
Stir in the evaporated milk and vanilla.
Whisk until the filling is smooth and pourable.
Pour the filling into the crust.
Bake at 425°F for 15 minutes.
Reduce the oven temperature to 350°F.
Continue baking for 35–45 minutes.
Check for doneness; the center should jiggle slightly but not slosh.
If the crust browns too quickly, cover edges with foil.
Remove from the oven when set.
Cool completely on a rack.
Refrigerate for at least 2 hours before slicing.
Slice and serve.
