Serve this cheesy casserole at your next dinner party, take it to the neighborhood potluck, or drop it off for a friend in need. You can even prep this dish ahead of time and store it in the freezer for months; perfect for when you need a hearty and nutritious meal in a pinch!

Give this creamy, salty casserole a bit of a kick with some spicy ingredient swaps! Trade the shredded cheddar cheese for pepper jack and the grilled chicken for a spicy breaded or glazed chicken. You can also toss in some red pepper flakes, buffalo sauce, diced jalapeños, or tabasco to really turn up the heat! The resulting spicy chicken broccoli rice casserole might be even more addicting than the original!

Combine two classic comfort dishes to create chicken broccoli bacon ranch casserole! Simply add some crispy chopped bacon and a packet of ranch dressing mix to the rice mixture. Bake, serve, and enjoy as normal!

Not a huge fan of broccoli? You can omit it or swap it out for another type of vegetable. Cauliflower, peas, carrots, bell peppers, mushrooms, and asparagus would all be great additions to this dish.

Frequently Asked Questions

Do you cook rice before adding it to casserole?

For this recipe, you need to completely cook the rice before adding it to the casserole. Uncooked rice takes a long time to soften in the oven—by the time it’s no longer crunchy, the broccoli would be mush. The good news is that you can use almost any kind of precooked rice in this dish—minute rice, jasmine, brown, and cauliflower rice all work!

What to serve with broccoli rice casserole?

I like serving this comfort dish alongside other classic and hearty side dishes. Homemade dinner rolls, roasted smashed potatoes, creamed corn, and bacon-wrapped asparagus are some of my favorite sides to pair with this casserole.

Do you cook casserole covered or uncovered?

Because all the ingredients in this casserole are precooked, you can bake it uncovered! You want a lot of the moisture in this dish to evaporate so that your broccoli chicken rice casserole comes out creamy and scoopable.

How to Store Cheesy Chicken Broccoli Rice Casserole

If you have any cheesy chicken broccoli rice casserole leftover, I recommend storing it in an airtight container in the fridge for up to 5 days. Any leftover casserole can be reheated in the microwave in 30-second increments; don’t forget to stir it periodically! Heat until warmed through and add an extra splash of chicken broth if the mixture seems too dry.

Chicken broccoli rice casserole is also a great dish to make ahead of time! Simply prepare the dish as normal, top it with shredded cheddar cheese, cover it with a layer of plastic wrap or tin foil, and store it in the fridge for up to 3 days or in the freezer for up to 3 months. Allow any frozen casserole to thaw overnight before baking as normal.

Expert Tips and Tricks

  • You can used steamed frozen broccoli or sautéed fresh broccoli in this dish; both are delicious!
  • I like to use a sharp cheddar cheese because I find that the flavor cuts through the creaminess of this dish quite nicely. However, you can also use a medium or mild cheddar in this chicken broccoli rice casserole.
  • If possible, shred your own cheese to use in this recipe. Pre-shredded cheese won’t melt as well, leaving your casserole goopy instead of thick and creamy.
  • Boost the homecooked flavor of this dish by replacing the dried spices with fresh garlic and onion! Sauté these two vegetables together until softened before adding them to the casserole.
