Spread rice mixture into prepared pan. Top rice with the remaining fried onions.
I use a whole rotisserie chicken for the cooked chicken in this casserole. Remove the skin and bones and discard. Depending on the size of your chicken, you should get four cups chicken.
What can I add to the casserole? Feel free to add any of your favorite vegetables. Broccoli, bell pepper, peas, or celery. Anything goes!
I use cheddar cheese. Feel free to use your favorite flavor or grated cheese.
Can Chicken Rice-a-Roni Casserole be made in advance? Yes! Assemble the casserole and cover the baking dish with tin foil. Refrigerate overnight.
You may need to add a few minutes to the cooking time if baking the casserole straight from the refrigerator.
Can Chicken Rice-a-Roni Casserole be frozen? Yes! Assemble the casserole and cover the dish with plastic wrap and aluminum foil. Place the dish in the freezer and freeze. The casserole will keep up to 3 months in the freezer.
