Apple pies can be baked ahead of time and frozen successfully if you use the right technique. This means you can make the most of an apple-picking session or a bumper harvest from your own apple trees to make a huge batch of pies to capture the essence of fall. Choose an area of your freezer where you won't be adding and removing a lot of items so your pies stay undamaged while they're in there. Apple pies will stay fresh for 4 to 6 months in the freezer.
Remove the baked apple pies from the oven and let them cool to room temperature.
Place the baked apple pies in the freezer, without covering them. Leave them to freeze completely, which usually takes about 4 hours.
Remove the baked apple pies from the freezer once they're frozen solid. Check to make sure they are frozen by touching the center of each pie. If there is still a trace of warmth or the pies feel soggy, return them to the freezer for another hour.
Wrap the baked apple pies in plastic wrap once frozen. Place the wrapped pies in individual freezer bags, label with the date and squeeze the bags to remove as much excess air as possible. Return them to the freezer.
To thaw the pies, remove them from their freezer bags, unwrap and allow them to thaw at room temperature for 2 to 3 hours. Place in the oven and warm at 350 degrees Fahrenheit for 15 to 20 minutes, or until a knife inserted in the center comes out warm. A vacuum sealer can be used to remove air from the freezer bags, if you have one. This helps keep the pie fresh-tasting.
Do not refreeze baked apple pies once they have been thawed. This will degrade the quality of the filling and may result in freezer burn. Instead, store any leftovers in the refrigerator for up to one week.
