Preheat your oven to 425°F. If using a frozen pie crust, remove it from the freezer. If using a homemade crust, lightly grease a pie dish and place the crust inside.
In a large mixing bowl, combine the pumpkin puree, sweetened condensed milk, eggs, ground cinnamon, ginger, nutmeg, and salt. Mix until the ingredients are well blended.
Pour the mixture into the pie crust. Bake in the preheated oven for 15 minutes.
After 15 minutes, reduce the oven temperature to 350°F and continue baking for an additional 35 minutes.
Remove the pie from the oven and let it cool on a wire rack for about 15 minutes before serving.
Optionally, top each slice with whipped cream for added deliciousness.
