Every chicken pot pie I make is a little different, since I don't follow a set recipe.
I boil the chicken in water with salt/pepper/onion/celery. Remove the chicken and add diced potatoes and carrots to the broth, sometimes peas if I'm feeling sassy. Boil for 15 minutes.
Make a "Cream Of Chicken Soup" using some of the chicken broth, heavy cream, butter, and flour.
Shred the chicken. Mix the veggies, broth, chicken, and homemade cream of chicken soup together.
I use 2 refrigerated pie crusts. One on the bottom of the pie dish, then add the filling, then another on top; pinch it closed and then give it an egg bath.
Bake for 30 minutes at 350.
I usually make 6-8 of these at the time, and so quantities are hard to nail down. We have lots of elderly family nearby, and I cook for all of them on Monday nights, and this is a favorite - so I do it once a month in the winter months. Sometimes we'll have leftovers, so I'll freeze them.
I will say that it was daunting when I first decided to make chicken pot pie - seemed complicated - but it's really easy and a good choice to feed a crowd.
