Yes, unbaked pumpkin pie is well suited to freezing. If you plan to freeze pumpkin pie, follow the recipe instructions up to the point of spreading the filling into the pie crust then wrap it well in several layers of plastic wrap and place it into a large freezer bag. Make sure to use a metal or disposable foil pie tin when freezing unbaked pies. Freeze the pie for up to 3 months. The quality of the pie will deteriorate the longer it is frozen. When you're ready to bake the pie bake it frozen, do not thaw it first. Preheat the oven to 425˚F with a cookie sheet or sheet pan in it. Place the frozen pie onto the hot cookie sheet. The heat from the cookie sheet helps cook the bottom pie crust. Bake the pie at 425˚F for the first 15-20 minutes and lower the oven temperature to 375˚F until its done. The total baking time will be around 1 hour.
