Tyler Florence from Food Network shows us how to make chicken pot pie in one pot. First sauté carrots, onions, and celery in extra virgin olive oil. Next add 2 tablespoons of flour. Add chicken broth and heavy cream. Season it with salt, pepper, and herbs. It will thicken before your eyes. Take some chicken and add it to the mixture. Next add frozen peas and small potatoes. You can use frozen pastry for the base. Use a crock to cut out the base. Fill the crock with the mix and add the pastry to the top. Bake it until the pastry is golden.
