Pre-heat the oven to 375°F.
Pour pumpkin pie filling into the pre-baked crust; only fill the crust about 3/4 of the way up.
Place in the pre-heated oven.
After 25 minutes of baking, be sure to cover the edges of the crust with aluminum foil or use a pie crust shield to prevent the edges from getting too brown.
Check for doneness at minute 50, 55 and 60, etc.
Bake the pie until the center is almost set; about 55 to 60 minutes give or take; expect a small part of the center to be wobbly.
Once done, transfer the pie to a wire rack and allow to cool completely for at least 3 hours.
Once completely cooled, cover tightly and place in the refrigerator for up to 5 days.
Serve with whipping cream or Cool Whip.
