Yes and yes! Bake the chicken pot pie with biscuits, then allow it to cool completely. Wrap tightly and freeze for up to 2 months. Then, thaw the chicken pot pie casserole completely and reheat. Another option is to assemble the dish as directed but skip the baking. Wrap it tightly and freeze for up to 2 months. Then, thaw overnight in the fridge, take it out of the fridge for about 30 minutes, and bake as directed. You can also freeze this without topping it with the biscuits. Just thaw completely and top with fresh biscuits, then bake as directed.
