To freeze a pumpkin pie, first allow the pie to cool down completely after baking. Once it is cool, wrap it in plastic wrap and then a layer of tin foil. Make sure to place the pie on an even surface in the freezer.
Pumpkin pie can be kept in the freezer for up to a month. To prevent the smell of other food from affecting your pie, store it away from strongly scented items and keep a box of baking soda in the freezer.
To thaw the pie, allow it to defrost in the refrigerator for four to eight hours before heating it.
