For best results, place frozen fruit pies directly in the oven without defrosting. In addition, cooking frozen pies on a baking sheet or pizza stone produces a crispier, golden brown crust.
Fruit pies can remain in freezer for up to four months without losing flavor. Once baked, fruit pies keep for up to two days at room temperature. After two days, you can loosely cover and store the pie in the refrigerator for an additional two days. To freeze a fresh pie, place the uncovered fruit pie in the freezer until solidly frozen. Then, wrap the pie tightly or store in a plastic freezer bag before returning it to the freezer.
