In a large bowl, whisk together pumpkin puree, granulated sugar, brown sugar, pumpkin pie spice, and salt.
Incorporate wet ingredients. Gradually whisk in the evaporated milk and eggs until the filling is smooth and well combined. Avoid overmixing, which can create air bubbles.
Pour pumpkin filling into the prepared pie crust.
Bake for 15 minutes.
Reduce oven temperature to 350°F (175°C) and bake for an additional 40-50 minutes, or until filling is set but still slightly jiggly in the center.
Let cool completely before slicing and serving.
Notes
For a crispier crust, blind bake the pie crust before adding the filling.
Store leftover can be stored covered in the refrigerator 3-4 days.
