Found this on the net.....For 9" pie
NOTE: You can bake both pies, or cover and freeze one potpie for up to 3 months.
To use frozen potpie, remove from the freezer 30 minutes before baking. Cover pie loosely with foil. Place on a baking sheet. Pre heat oven to 375-degree F and bake until lightly browned and bubbly, about 40 to 45 minutes. Oven times will vary.
Hope this helps! Enjoy your pie!
