Pumpkin pies are fine to freeze, but they may have a slightly different texture once they have thawed. The taste should be the same as a fresh pumpkin pie.
Before freezing a pumpkin pie, make sure that the pie is thoroughly cooled. Then, wrap the whole pie in a plastic wrap, making sure that every bit of it is covered. Next, wrap it in an aluminium foil to prevent the pie from picking up odors from the freezer. Place it in the freezer where it can lay flat. Pumpkin pies can be stored in the freezer for up to two months. Do not freeze a pumpkin pie that has been previously frozen.
