Fruit is perishable, so allowing an uncooked fruit pie to thaw at room temperature will breed bacteria. However, if the fruit pie is baked at the wrong temperature for the wrong amount of time while still frozen, you will often end up with a pie that has an overly cooked shell, and an under baked filling. To remedy this, you must thaw an uncooked, frozen fruit pie in the oven. A fruit pie that was cooked prior to freezing has different thawing requirements.

Thawing an Uncooked Frozen Fruit Pie

Preheat the oven to 425 degrees Fahrenheit.

Place the frozen fruit pie on a rack situated in the lower 1/3 of the oven for 15 to 20 minutes to thaw it.

Cut vents in the fruit pie after 10 minutes, if necessary. These vents are simply small slits that allow steam to escape as the pie bakes, so the pie does not become soggy.

Reduce the heat to 375 degrees Fahrenheit to cook the pie after thawing. Bake it for an additional 40 to 45 minutes, or until the crust is golden brown.

Thawing a Cooked Frozen Fruit Pie

Place the cooked frozen fruit pie on the counter or other flat surface, and allow it to sit at room temperature and thaw for three hours. As an alternative, place the cooked pie in the refrigerator and allow it to thaw overnight.

Stick a knife or fork through the fruit pie to verify that it is no longer frozen in the center.

Preheat oven to 425 degrees Fahrenheit. Place the fruit pie in the oven for 15 minutes to warm it.
