In a medium bowl combine the milk, rice, soup and seasoned salt if desired. Mix well. Pour mixture into a lightly greased 9x13 inch baking dish. Add the chicken pieces.
Cover dish tightly with aluminum foil and bake in the preheated oven for approximately 90 minutes or until rice is done, stirring every 30 minutes. Uncover the dish and bake for another 15 minutes to allow the rice to brown.
