Cook chicken and cut into bite-size pieces. I usually use my Instant Pot to cook the chicken. 

Mix chicken, frozen vegetables, cream of chicken soup, and sour cream together in a large bowl.

Add poultry seasoning and stir well.

Place one of the pie crusts in an 8 3/4 or 9 inch pie pan. Use a foil pan if you plan to freeze your pot pie for a later date. 

Add the chicken mixture. to the pie pan on top of the bottom crust.

Cover with the top crust and crimp the edges to seal. Make cuts in the crust for steam to escape.

Freeze for later or bake at 350 degrees for approximately 1 hour and 10 minutes or until golden brown.
