Set your oven to 425°F and while it preheats, begin with preparing the pie filling. Start with a large mixing bowl, combine the pumpkin puree, sugar, salt, cinnamon, ginger, and nutmeg until smooth.
Beat in the eggs until well combined.
Gradually stir in the condensed milk until the mixture is smooth.
Pour the pie filling mixture into the unbaked pie crust.
Bake the pie in the preheated oven at 425°F for 15 minutes.
Afterward, reduce the oven temperature to 350°F and continue baking for an additional 40-50 minutes or until a knife inserted near the center comes out clean.
Let cool before serving. Option to add a dollop of whipped cream to top the pie slice, and enjoy!
