Bake your pumpkin pie according to your favorite recipe.
Allow the pie to cool completely before freezing.
Wrap the pie tightly in plastic wrap, making sure to cover the entire surface of the pie.
Place the wrapped pie in a freezer-safe bag or container and label with the date.
When ready to thaw, remove the pie from the freezer and let it thaw in the refrigerator for several hours or overnight.
Reheat the pie in the oven at 350°F for 10-15 minutes to refresh the crust and warm the filling.
