This avocado ranch chicken casserole is a one pan dream meal! The avocado ranch dressing gives it so much flavor with lots of rice and mushrooms.
Pre-heat the oven to 350 and get out a 9 x 13 casserole dish. Place the chicken in it and season it generously with the salt, pepper and garlic powder. Evenly distribute the mushrooms and rice over and around the chicken, then pour in the dressing and chicken stock. Finally, sprinkle the parmesan evenly on top. Bake the casserole for an hour, taking it out and stirring the rice every so often. When it is done, place the sliced avocado on top and serve immediately! Enjoy!!
