Preheat your oven to 200°C (392°F).
Take your chilled pie crust dough and roll it out on a floured surface to fit your pie dish. Make sure it's large enough to cover the bottom and sides of the dish.
Place the rolled-out dough into the pie dish and trim any excess.
Pour the cooled chicken and vegetable filling into the pie crust.
Roll out the remaining dough to create a lid for the pie. Place it on top of the filling.
Seal the edges of the pie crust by pressing them together with a fork or your fingers.
Cut a few slits in the top crust to allow steam to escape.
Optionally, brush the top crust with a beaten egg to give it a nice golden color.
Place the pie in the preheated oven and bake for 30 minutes, or until the crust is golden brown and the filling is bubbling.
Remove from the oven and let it cool for a few minutes before serving.Enjoy your delicious homemade chicken pie with a flaky, buttery crust and a savory filling!
