YES! But, to me, it feels redundant to thaw puff pastry and then re-freeze it. Instead, make the filling and store it in the freezer in a baking dish, then when you'd like to bake the pot pie thaw the puff pastry, drape it over the baking dish (it's OK if the filling is still frozen), and bake!u003cbr/u003eu003cbr/u003ePRO TIP TO AVOID SHATTERED BAKING DISHES: When baking things from frozen, place the dish in a COLD oven, turn the oven on to the desired temperature, and let the dish and casserole filling warm gently as the oven heats up.
