There's nothing like a steaming hot chicken pot pie on a cold winter day and if you're starting with a frozen pot pie, it's important to know how to properly reheat the pie. To ensure that you end up with a perfectly flakey crust with a thoroughly cooked filling, reheat your pie in the oven.
Preheat the oven to 350 degrees F.
Crack an egg into a bowl with a teaspoon of water or milk. Whisk together until the egg is completely beaten.
Brush the crust of the chicken pot pie with the egg wash and cover with aluminium foil. Place the pie in the oven on a baking sheet.
Remove the pie from the oven after 15 minutes, remove the foil and brush the top again with the egg wash.
Place the pie back in the oven uncovered for another 15 minutes until the pie crusts is golden brown and the temperature inside the pie is at least 165 degrees F. Serve hot.
