Preheat oven to 350 degreesTo prepare the pumpkin pie filling, begin by whisking together the pumpkin, 3 eggs, and brown sugar until they are well combined.
Next, incorporate the cornstarch, salt, cinnamon, ginger, nutmeg, cloves, pepper, heavy cream, and milk. Whisk vigorously until all the ingredients come together.
Gently pour the pumpkin pie filling into your pie crust, filling it to about 3/4 full. If you're using a deep dish pie dish as recommended, you should have just a little filling left over.
Bake the pie until the center is almost set, which usually takes about 55-60 minutes. You'll notice a slight wobble in the center, but that's perfectly fine.
Around the 25-minute mark, be sure to cover the crust edges with aluminum foil to prevent excessive browning. Check for doneness at 50, 55, 60 minutes, or as needed.
Once the pie is fully baked, transfer it to a wire rack, and allow it to cool completely for at least 3 hours before adding any garnishes and serving.
