Chicken pot pie: crust and filling need different preparation

Useful to know

Classic Chicken Pot Pie prepares the pastry separately from a thickened filling containing already cooked chicken. Preparation of both parts precedes their combined bake. [1]

This is not an instruction to enclose arbitrary raw ingredients beneath pastry. Follow the complete method and doneness guidance. Resting before serving helps produce a more stable portion rather than merely delaying the meal.
