Pot pie, chicken or otherwise, is the height of homey comfort food. Topping it with a pastry crust is all fine and good, but to up the nurturing quality (and ease of recipe) I suggest topping yours with scones.
The above video can walk you through the whole pot pie-making process, but you can top any pot pie with any scones (or biscuits in the US) of your choosing. Homemade is always extra special, but I've done this with pre-packaged scones, and everything turned out deliciously. To make a basic pot pie filling, start by sauteing your favourite vegetables (carrots, onion, peas, and mushrooms are my faves) in some butter. Once everything is nice and soft, throw some flour in there and mix it around to coat the veggies. Once the flour is nice and golden, stir in some milk and stock to make your gravy. Add in some chicken (or omit to keep it vegetarian friendly), pour it in a casserole, top with scones, and bake until the scones are golden brown and the filling is hot and bubbly.
