Preheat your oven to 350F. Then cook your chicken. I like to boil mine for this recipe, but you could brown it. Rotisserie chicken works too. Either way, after the chicken is cooked, dice up 4 cups and set aside.
Add the Cream of Chicken soup cans to a large mixing bowl.
Add the thyme and Italian seasoning to the soup and mix.
Melt the butter and add into the soup and mix well.
Add the frozen vegetables to the soup and mix.
Add the chicken and plenty of fresh ground pepper, and mix well. Set aside.
Open the pie crust and put the first layer down into your deep dish pan. Fix and trim around the edges as desired.
Fill the deep dish pie pan with the pot pie filling, patting down with a spatula until it is well filled and somewhat smooth on the top.
Layer over the second pie crust and trim around the edges as desired. You can see in the picture, I re-rolled and made some little pretty leaf like designs on the top... get as creative as you'd like!
The trick to getting a beautifully golden crust is to take a brush, dip it into the egg, and spread generously around the raw dough. Make sure to poke a few small holes to let some steam escape.
Sprinkle the top with a dusting of kosher salt. Bake at 350F for about 40-50 minutes until the crust is golden brown.
