Preheat the oven to 425°F (220°C).

Place the pre-made pie crust in your 9-inch pie dish, pressing it gently into the bottom and sides.

In a mixing bowl, combine pumpkin puree, evaporated milk, sugar, eggs, cinnamon, ginger, nutmeg, and salt. Whisk until smooth.

Pour the filling into the prepared pie crust, ensuring it's evenly distributed.

Bake in the preheated oven for 15 minutes, then reduce the temperature to 350°F (175°C) and bake for an additional 30 minutes.

Check for doneness by inserting a knife into the center; it should come out clean.

Remove the pie from the oven and let it cool on a wire rack.

Slice the pie and serve plain or with whipped cream.
