Any sort of pie can be hard to tackle. If you're not following a family recipe, pick one from the internet with an instruction video and take notes to ensure success next time too.
Most pot pie recipes require a small number of ingredients, so making each item high-quality is essential. Use the freshest chicken and vegetables possible for the best flavor.
For a rich flavor, use the whole chicken to make a stock for your filling, and use both the light and dark meat. Crispy roast chicken skin can even be used to garnish the pie.
Fresh herbs like thyme, parsley, sage, and chives are great add-ins for the filling or pastry dough. They can also be used to garnish for aesthetic value and flavor.
Whether you cook mushroom stems in the stock, use them as a main veggie, or add a pinch of mushroom powder to the filling, these fungi will always amp up a pot pie's savory factor.
