In a large saucepan over medium low heat combine the chicken, cream of mushroom soup, cream of chicken soup, cream cheese, sour cream and 2/3 of the biscuit crumbs. Mix well and cook until all blended together and cream cheese has melted.
Preheat oven to 180 degrees C.
Transfer casserole mixture into a lightly greased 20x30cm baking dish and top with remaining crumbs.
Bake at 180 degrees C for about 15 minutes or until biscuits turn golden brown. Spoon into bowls and enjoy!
