Chicken, Rice, and Mushroom Casserole

Sharing is caring!

Chicken Casserole serve on a plate with peas.

Cooler weather calls for comforting, hearty meals. This chicken and rice casserole with mushrooms fits the bill. Pecans on top add a crunchy butteriness. It’s a great way to use up leftover chicken (or turkey). A rotisserie chicken can be used instead. This recipe is made from scratch so it will appeal to those who have an aversion to canned cream soups. Best things about casseroles is they’re a complete meal in one dish and they make a delicious dinner any night of the week. I added some frozen peas as an easy side just to lighten (and brighten) the meal up a bit.

This is a recipe from From a Southern Oven: The Savories, The Sweets

that I’ve adapted some. From A Southern Oven is a new addition to my cookbook collection and it has lots of interesting recipes that I can’t wait to try including Muscadine Mystery Cake, Sweet Potato Schnitzel, ,and Pecan-and-Rice Stuffed Vidalias. There’s also a recipe for Baked Curried Deviled Eggs. In all my years of looking through cookbooks I’ve never seen such a recipe.
