Freezing your beef pot pie is a WONDERFUL idea! I’d actually recommend doubling your groceries so that you can make two pies at once – one for dinner tonight and one to store in the freezer for a pinch-hitter dinner. For your frozen pot pie, I recommend skipping the final bake (just place the raw crust over the filling) and then freeze once it’s wrapped up well (parchment followed by 2 layers of foil). Be sure to freeze your pot pie in the dish you’ll use for your final bake when you’re ready, because transfer will likely be pretty tricky. Put it in your refrigerator 2 days before you want to enjoy it for dinner so it has plenty of time to thaw.
