In a 2 litre ovenproof casserole dish, layer half of the chicken mixture, spreading evenly across the bottom of the dish, then half of the rice, then half of the fried onion. Repeat another layer. Cover and seal dish tightly with tin foil, shiny side down. Bake the biryani in the oven for 30 - 45minutes. Oven temperatures may vary, so after 30mins, test the chicken and potato to see if cooked.
