Chicken, Mushroom, Broccoli, and Rice Casserole

An old friend gave me this easy chicken, mushroom, broccoli, and rice casserole recipe years ago when I first met my husband, and it’s always a crowd favorite when I make it. My girlfriend Currié and her family came for dinner to celebrate her upcoming birthday, and I made her two of her favorite recipes–this casserole and fresh brownies. The casserole was delicious and paired nicely with a house salad and some crusty bread. We had a great evening celebrating a special birthday.
Chicken, Mushroom, Broccoli, and Rice Casserole:
Ingredients:
- 1 (4 oz) box of Farmhouse Long Grain & Wild Rice (or your favorite brand), prepared per instructions
- 2 tbsp butter or olive oil
- ½ onion, diced
- 1 lb mushrooms, quartered
- 1 stalk of celery, diced
- 1 cup of broccoli florets
- 2 cooked chicken breasts, cubed (I use leftover roasted chicken meat)
- 1 (10 ¾ oz) can of Cream of Chicken soup
- 1 (10 ¾ oz) can of Cream of Celery soup
- ½-¾ cup mayonnaise, to taste
- 1 (6 oz) can of sliced water chestnuts, drained & diced
- Sea salt and freshly cracked pepper, to taste

How to Make a Chicken, Mushroom, Broccoli, and Rice Casserole
Preheat the oven to 350 degrees.
Prepare the box of rice according to the package instructions in a small saucepan, and set aside to cool until needed.
In a large skillet, add 1 tablespoon of butter or oil and cook the mushrooms until golden brown. Remove from the skillet and set aside until needed.
Add the remaining tablespoon of butter or oil to the large skillet and cook the onions and celery, stirring frequently, until soft, about 5 minutes.
Using a steamer, steam the broccoli until fork-tender, then set it aside to cool.
In a large bowl, combine the rice, mushrooms, onion, celery, broccoli, chicken, cream of chicken soup, cream of celery soup, mayonnaise, water chestnuts, sea salt, and freshly cracked pepper, to taste, together and mix well.
Pour into a baking dish and heat uncovered for 30 minutes. Let cool for a few minutes before serving. Enjoy.
Side Note: For added decadence and/or texture, top the casserole with French’s crispy fried onions, crushed Ritz crackers, or panko crumbs after the first 15 minutes of baking. Continue baking for the remaining 15 minutes.

This recipe is one of my favorite. I’m allergic to onions so I’ve made it many times without them and by upping the celery to compensate
Going to be cooking what looks like a delicious casserole recipe this weekend. How much rice? How much cooked rice should the equivalents be?
I always use 1 box of Farmhouse Long Grain & Wild Rice .

How much rice is in a box?
The box says 4 0z of rice (about 1/2 cup).

OMG…. since chicken, mushrooms, broccoli, and rice are among my very favorite ingredients in any casserole, l definitely plan to make this one!. My hubby doesn’t care for water chestnuts, so I’ll leave them out (but personally, I love the crunch). I’ll use “Heart Healthy” Campbell soups…. since they contain 33% less sodium & fat (so I’ll see how that works out). Thanks for (yet) another lovely recipe!
How big is the box? Or how many cups would that equal?
Marty,
I use a 4-oz box of Long Grain and Wild Rice Herb & Butter flavor.
