Preheat your oven to 375°F (190°C).
Place the mini pie crusts on a baking sheet. If using a homemade crust, roll it out and cut into small rounds to fit your mini pie pans.
In a mixing bowl, combine the pumpkin puree, sugar, cinnamon, nutmeg, salt, and eggs. Whisk until well combined, then stir in the heavy cream until smooth.
Pour the pumpkin filling into each mini pie crust, filling them about 3/4 full to allow for expansion.
Bake in the preheated oven for 25-30 minutes or until the filling is set and a toothpick inserted comes out clean.
Remove the pies from the oven and allow them to cool on a wire rack. They will continue to set as they cool.
Once cooled, serve them as is or top with whipped cream and a sprinkle of cinnamon for a delightful touch.
