A baked apple pie can be stored unrefrigerated and at room temperature for up to two days. Once the pie has been cut into, it should be covered with foil or plastic wrap. An unbaked apple pie must be stored in the refrigerator or frozen.
To have a baked apple pie keep longer, it can be stored in the refrigerator for an additional two to three days or frozen. If it's frozen, the pie begins to lose its quality after roughly four months. An unbaked apple pie has the same freezer shelf life as a baked apple pie. However, a frozen unbaked apple pie should be baked without thawing ahead of time, and a frozen baked apple pie should be place in the refrigerator to defrost.
