I LOVE chicken pot pie, it is my ultimate comfort food, soI was very excited when I found this easy and fairly quick recipe...no more frozen pot pies for me. I don't like cooked carrot so I leave it out, just personal preference. I would NOT leave out or substitute anything for the sherry. It is one of the main flavor components. The recipe uses a 13 x 9 baking dish, but I've also made them in small aluminum pot pie pans. The only problem with the small tins is reheating can not be done in the microwave. I like to make a batch in the tins and cook a few and freeze the rest uncooked to have later. The recipe calls for puff pastry, but the filling lends itself to a variety of toppings, pie dough, buttermilk biscuit dough or mashed potatoes. Super easy and super tasty! Enjoy!
