Grab a large skillet and melt your butter over medium heat. Toss in the chopped onion and potato cubes, then cook them for about 10 minutes, stirring often so nothing sticks or burns.
02 -
Sprinkle the flour over your veggies and stir it around constantly for about 2 minutes. Gradually pour in the warm chicken stock and heavy cream while stirring continuously. Season with poultry seasoning, salt, and pepper, then turn the heat down to low.
03 -
Mix in your frozen vegetables and leftover turkey pieces. Let everything cook together for 5 minutes, then transfer the whole mixture to a bowl and let it cool down completely.
04 -
Heat your oven to 425°F. In a small bowl, whisk together the egg with a teaspoon of water to make an egg wash.

Dust your work surface with a bit of flour, then roll one pie crust into a 12-inch circle. Carefully lay it into your 9-inch deep pie dish, letting it settle into the bottom and sides.
06 -
Once your filling has cooled completely, pour it into the crust-lined pie dish. Roll out your second crust and drape it over the top. Trim any excess dough, leaving about an inch of overhang, then fold the edges under and crimp them however you like. Brush the entire top with your egg wash, then cut 4-5 small slits in the crust so steam can escape. Set the pie on a rimmed baking sheet.
07 -
Slide the pie into your preheated oven and bake for 20 minutes at 425°F.
08 -
Lower the temperature to 350°F and keep baking until the crust turns a beautiful deep golden brown and you can see the filling bubbling through the vents - this takes about 30 more minutes.
09 -
Let your pot pie rest for 10 to 15 minutes before slicing - this helps the filling set up nicely. Finish with a sprinkle of flaky salt and cracked pepper right before serving.
