I have yet to make an actual chicken pot pie. I always opt for the baking powder biscuit version. Oh crust, so much rolling, so much chilling, so much pre- baking. I have no patience for these.
Cook everything in advance. Make some cream sauce with chicken stock. Stick it in a pot and cover it with biscuits.
It’s a hearty meal as winter approaches as you try to figure out what the heck to do with this big squash.
