Broth: 1 (3 pound) chicken 1 onion, coarsely chopped 2 carrots, coarsely chopped 2 stalks celery, coarsely chopped 2 cloves garlic, smashed 6 sprigs parsley 1 sprig thyme 1/2 teaspoon black peppercorns 2 bay leaves Pot Pie: 1 pound skinless, boneless chicken breast halves - cubed 1 cup sliced carrots 1 cup frozen green peas 1/2 cup sliced celery 1/3 cup butter 1/3 cup chopped onion 1/3 cup all-purpose flour 1/2 teaspoon salt 1/4 teaspoon black pepper 1 3/4 cups chicken broth 2/3 cup milk 2 (9 inch) unbaked pie crusts

Broth:
Place everything in a large stock pot, cover with 4 inches of water, bring to a boil, reduce the heat and simmer for 1 hour.
Pull the meat off of the chicken and reserve for another use.
Strain the solids from the broth and discard them.
Optionally, let the broth cool in the fridge over night and skim off any fat before using.

Pot Pie:
Preheat oven to 425 degrees F (220 degrees C.)
In a saucepan, combine chicken, carrots, peas, and celery. Add water to cover and boil for 15 minutes. Remove from heat, drain and set aside.
In the saucepan over medium heat, cook onions in butter until soft and translucent. Stir in flour, salt, pepper, and celery seed. Slowly stir in chicken broth and milk. Simmer over medium-low heat until thick. Remove from heat and set aside.
Place the chicken mixture in bottom pie crust. Pour hot liquid mixture over. Cover with top crust, seal edges, and cut away excess dough. Make several small slits in the top to allow steam to escape.
Bake in the preheated oven for 30 to 35 minutes, or until pastry is golden brown and filling is bubbly. Cool for 10 minutes before serving.
