Preheat the oven to 425°F (220°C).
In a medium mixing bowl, combine Libby’s pumpkin pie mix, sugar, salt, cinnamon, and ginger. Mix until smooth.
Beat in the eggs gradually, ensuring the mixture is fully incorporated.
Slowly stir in the evaporated milk until the filling is uniform.
Pour the filling into the prepared pie crust. Smooth the top with a spatula.
Bake for 15 minutes at 425°F, then reduce the temperature to 350°F (175°C) and continue baking for 40–50 minutes, or until a knife inserted near the center comes out clean.
Let the pie cool for at least 30 minutes before slicing. Serve with whipped cream if desired.
