If you haven’t already prepared your pumpkin pureé, remove the stems from three cured pie pumpkins. Pierce the skin with a knife, place on a lined baking sheet, and bake in a preheated 350°F oven for 20 minutes or until easily pierced with a fork.
Remove the pumpkins, allow to cool, separate the flesh from the skin and seeds, and pureé smooth with an immersion blender.
Get three pie pans and roll out your pie dough. Lay the dough in the pans and crimp the edges, or make any fancy designs you’d like. Place the pie crusts in the refrigerator until ready, and preheat the oven to 350°F.
Pull your pie crusts from the refrigerator and pour the prepared custard equally between 3 standard-sized eight or 9-inch pie crusts, two deep-dish pie crusts or pour into a greased 9×13-inch pan for a breakfast pumpkin custard.
Place your homemade pumpkin puree in a bowl and add the eggs, pumpkin pie spice, salt, vanilla, milk, and brown sugar.
Use an immersion blender to blend until silky and smooth. Alternatively, mix all your ingredients in a blender or food processor.
Bake at 350°F for approximately 45-55 minutes (depending on pie size). The pie is finished baking when the custard is completely set, but still just a tad jiggly in the center (not watery or runny).
Let the pies cool on a wire rack for 20 minutes or so (until they’re just above room temperature). This allows the pies to set completely. Serve with a generous dollop of homemade vanilla ice cream, whipped cream, or a drizzle of caramel sauce.
