Recipe testing this chicken and rice casserole, was one of the easiest dinners I’ve made in a while. It’s like the classic southern stick of butter rice side dish, just with chicken and mushrooms.
No mixing bowl needed, just dump the ingredients into a casserole dish, mix, cover, and oven bake.

Ingredients
Chicken - Boneless chicken thighs are recommend, they stay juicier when baked in the oven for a long periods of time. Other options like chicken breast or tenderloins can be substituted.
Rice - Any long grain rice, I used jasmine.
Mushrooms - Fresh sliced is best, white or brown Bella’s. Canned and jarred mushrooms can be substituted.
Butter- I recommend unsalted to keep the sodium content low. Salted can be used if preferred.
Soup & Broth- Canned French onion soup and beef consommé.
Seasonings - Your favorite all-purpose spices to season the chicken. I used smoked paprika, poultry seasoning, onion and garlic powder.
Beef Consommé
You can substitute beef broth or beef bone consommé, but you will not get the same rich strong flavor.
Beef consommé is thicker with a gelatin texture. It really helps to bake up the rice to a nice dark brown color.

Baking Time
When you are making any oven rice bake, check the texture of the rice while it is baking. I recommend about 10 minutes prior to the full recommended bake time.
Oven heat and temperatures and rice cooking times can vary. You don’t want to overcook the rice.

How To Serve
This is a great one pan meal with starch and a protein. Since the oven is going cook or roast vegetables like green beans, broccoli, mixed veggies, or peas and carrots. Bread rolls, green salad, and fruit.
