How to Make Chicken Broccoli Rice Casserole | 1-Minute Video
Delicious, cheap and so simple. I didn’t have cream of chicken, so I used cream of celery. I’ll never do it any other way! I added some garlic powder and onion powder in as well. my 2yo and 4yo loved it, this is definitely going straight into the meal rotation

Before You Get Started
These key tips help the casserole cook evenly and make sure the rice turns out tender.
- Use long-grain white rice only. This recipe was developed and tested specifically for uncooked long-grain white rice. Other varieties (brown rice, wild rice, or instant rice) all absorb liquid differently and require their own cook times, so they won’t turn out well here.
- Keep the broccoli frozen. Frozen broccoli releases moisture as it cooks, which helps soften the rice and keeps the casserole from drying out. Baby florets are the best size for an even bite, but chopped fresh broccoli will work too as long as the pieces are small.
- Dice the chicken into small, bite-size pieces. Since everything cooks together in one dish, cutting the chicken small ensures it cooks through at the same rate as the rice. If you prefer, you can use about 2 cups of cooked, shredded chicken (such as rotisserie), which may shorten the baking time slightly.
- Cover the dish tightly with foil. Trapping steam is the most important part of dump-and-bake casseroles. A tight seal keeps the liquid in the dish so the rice can absorb it fully. If steam escapes, the rice can turn out undercooked or uneven.

How to Make Chicken Broccoli Rice Casserole
This easy dinner relies on simple ingredients and the dump-and-bake method. Everything cooks together in one dish, absorbing flavor as it bakes.
Step 1: Combine the Liquid Base
Whisk the condensed soup and water (or broth/milk) in a greased 9 x 13-inch baking dish until smooth. This mixture helps cook the rice, binds the casserole, and adds creaminess without extra steps.
Step 2: Add the Remaining Ingredients
Stir in the uncooked long-grain white rice, diced raw chicken, and frozen broccoli florets. Season with salt, pepper, garlic powder, onion powder, or any herbs you enjoy.
Good options include paprika, thyme, rosemary, basil, oregano, chives, seasoned salt, or parsley.
** Note: If you prefer, you can use about 2 cups of cooked, shredded chicken (such as rotisserie). The casserole may need slightly less baking time when starting with cooked chicken.
Step 3: Cover Tightly and Bake
Cover the dish tightly with foil so no steam escapes. This is the key to tender, fluffy rice.
Bake for 55-60 minutes, or until most of the liquid is absorbed and the rice is tender. Taste a small bite of rice to check doneness.
Glass or ceramic dishes may take a bit longer than metal pans, so adjust as needed.
Step 4: Add the Cheese
Fluff the rice gently with a fork, sprinkle cheese on top, and return the pan to the oven for a few minutes until melted.
Step 5: Serve
Let the casserole rest for a few minutes, then garnish with fresh herbs if you like.

Serving Suggestions
This casserole pairs well with a simple veggie or bread side. Try it with:

Preparation and Storage Tips
Make Ahead: You can assemble the casserole a few hours in advance, or even leave it covered in the refrigerator overnight before baking. The rice will start to soften and absorb some of the liquid as it sits, so you may need to decrease the baking time slightly. Don’t overcook the casserole or you’ll end up with gummy, mushy rice.
Storage: Leftovers will keep in an airtight container in the refrigerator for 3-4 days. The rice will dry out a bit as it sits, so you may need to stir in some additional broth or milk when you reheat the dish.
I don’t recommend freezing this dish since rice can turn mushy once thawed.
How to Reheat: Cover and reheat leftovers in a 350°F oven for 20-25 minutes, or until warmed through. You can also reheat individual portions in a microwave for about 1 minute.
Recipe Variations
- Swap out the broccoli for different vegetables. Frozen peas or corn, frozen mixed vegetables, sauteed sliced mushrooms, and diced or grated zucchini are all good options.
- Milk is a fine substitute for the broth or water.
- Top the casserole with other good melting cheeses, including Colby, Colby Jack, Monterey Jack, Pepper Jack, and mozzarella.
- Add buttered Ritz crackers, buttered seasoned bread crumbs, or buttered panko breadcrumbs at the same time that you add the cheese if you like a crunchy topping. This dump-and-bake chicken vegetable casserole even includes buttery stuffing mix on top.
- For a similar dish with pasta, try this dump-and-bake chicken pot pie pasta.
- Cooking for a smaller family? Cut all of the ingredients in half and bake the casserole in an 8-inch square dish. The cooking instructions remain the same.
Frequently Asked Questions
Can I use frozen broccoli?
Yes. Frozen broccoli works very well here and helps provide the moisture needed for the rice to cook properly.
Can I use a different type of rice?
No. Long-grain white rice is the only type that cooks evenly with this liquid ratio and timing. Minute rice, wild rice, and brown rice all require different amounts of liquid and won’t work with this dump-and-bake method.
Can I make this casserole ahead?
Yes. Assemble the dish and refrigerate it for several hours or overnight. Just note that the rice may soften slightly as it absorbs liquid.
Can I use rotisserie chicken?
Absolutely. Use about 2 cups of diced or shredded cooked chicken. The casserole may finish a little sooner in the oven.

Followed you before I became a Mom, but now as a first time mom I loved that this recipe took only 5 minutes to put together and I had something hot ready to eat and serve while our little 1 month old was in his bassinet. Thanks again! Added a little extra salt/pepper to prepared dish but overall very satisfying and easy. Thanks for sharing!

Loved it, but can be. salty
Thanks, Rachel! Definitely look for the “heart healthy” soup varieties, which have less sodium, and use low-sodium broth. That gives you a lot more control over the finished dish.
Great recipe to prepare for a crown. I prepared for 20 people, used cooked chicken and topped with Panko bread crumbs, cheese and butter mixture. Huge hit!
Thanks, Teresa! I’m so glad that it’s a hit with your friends and family. The crunchy bread crumb topping sounds perfect!
