Optional Topping

  • ½ cup shredded cheddar cheese
  • ½ cup crushed buttery crackers
  • 2 tablespoons melted butter

The cracker topping isn't required, but if you love a crunchy casserole topping, it's absolutely worth trying.

What You'll Need

  • 9x13-inch baking dish
  • Large mixing bowl
  • Small skillet, if sautéing fresh onion
  • Measuring cups and spoons
  • Mixing spoon
  • Aluminum foil

That's about it!

One casserole dish and one mixing bowl make cleanup pleasantly manageable.

Ingredient Substitutions and Additions

Chicken

Rotisserie chicken is one of my favorite shortcuts.

You can also use leftover roasted chicken, grilled chicken, or poached chicken.

Boneless skinless chicken breasts and thighs both work.

Rice

White rice is the classic choice, but brown rice works beautifully too.

You can even use a rice blend for extra texture.

Just make sure the rice is already cooked before adding it to the casserole.

Broccoli

Fresh broccoli gives you a little more texture, while frozen broccoli is incredibly convenient.

If using frozen broccoli, thaw and drain it first so excess water doesn't make the casserole watery.

Cheese

Sharp cheddar is my favorite because it provides plenty of flavor.

You could also use:

  • Monterey Jack
  • Colby
  • Colby Jack
  • Mild cheddar
  • Pepper Jack
  • A cheddar-Mozzarella blend

Cream of Chicken Soup

If you'd rather not use canned soup, you can substitute a homemade cream sauce.

A simple combination of butter, flour, milk, and chicken broth works well.

Sour Cream

Greek yogurt can be used instead of sour cream for a slightly tangier casserole.

Add More Vegetables

Want to sneak in a few more vegetables?

Try adding:

  • Peas
  • Carrots
  • Corn
  • Mushrooms
  • Bell peppers
  • Spinach

Just be careful not to add so many vegetables that the casserole becomes watery.

How to Make Chicken Broccoli Rice Casserole

Step 1: Preheat the Oven

Preheat your oven to 375°F.

Lightly grease a 9x13-inch baking dish with cooking spray or a little butter.

Step 2: Prepare the Broccoli

If using fresh broccoli, cut it into small bite-sized florets.

For the best texture, you can lightly steam or blanch the broccoli for a few minutes before adding it to the casserole.

You don't want it completely soft.

A little firmness is perfect because it will continue cooking in the oven.

If you're using frozen broccoli, thaw it completely and drain well.

Step 3: Make the Creamy Mixture

In a large bowl, combine:

  • Cream of chicken soup
  • Sour cream
  • Milk
  • Garlic powder
  • Onion powder
  • Salt
  • Black pepper

Stir until smooth.

This is going to become that creamy, savory sauce that brings everything together.

Step 4: Add the Chicken and Rice

Add the cooked chicken and rice to the bowl.

Stir gently until everything is evenly coated.

Step 5: Add the Broccoli

Fold in the broccoli and chopped onion.

Try not to mash the broccoli as you stir.

We want those little green florets to remain recognizable throughout the casserole.

Step 6: Add Cheese

Stir in 1½ cups of shredded cheddar cheese.

Save the remaining ½ cup for the top.

Now we're getting somewhere!

Step 7: Transfer to the Baking Dish

Spread the mixture evenly into your prepared 9x13-inch baking dish.

Use the back of a spoon to smooth the surface.

Step 8: Add the Cheese Topping

Sprinkle the remaining cheddar evenly over the casserole.

If you're using the optional cracker topping, combine the crushed crackers with melted butter and sprinkle them over the cheese.

Step 9: Bake

Cover the casserole loosely with aluminum foil.

Bake for about 25 minutes.

Then remove the foil and continue baking for another 15–20 minutes, or until the casserole is hot and bubbling and the cheese is melted and lightly golden.

If you love a deeply golden top, you can place it under the broiler for the final 1–2 minutes.

Watch it closely!

Cheese can go from beautifully golden to burned very quickly.

Step 10: Rest Before Serving

Let the casserole rest for about 5–10 minutes before serving.

I know it smells amazing.

But giving it a few minutes to settle makes it easier to scoop and helps keep the creamy filling from running all over the plate.

Tips for the Best Chicken Broccoli Rice Casserole

Don't Use Watery Broccoli

This is one of the biggest secrets to a good casserole.

If using frozen broccoli, thaw and drain it thoroughly.

Excess moisture can make the finished casserole soupy.

Use Cooked Rice

This recipe is designed for cooked rice.

Using uncooked rice without changing the liquid and cooking method can throw off the texture and cooking time.

Don't Overcook the Chicken

If you're cooking chicken specifically for this recipe, avoid drying it out.

Shredded rotisserie chicken is an easy option because it is already cooked and flavorful.

Shred Your Own Cheese

Pre-shredded cheese is convenient, but freshly shredded cheese often melts more smoothly.

Let It Rest

Those extra few minutes after baking really help.

The casserole becomes easier to serve and the sauce thickens slightly as it cools.

Don't Skimp on Seasoning

Chicken, rice, and broccoli are mild ingredients.

Garlic, onion, black pepper, and a flavorful cheese help make sure every bite tastes delicious.

Can I Make This Casserole Ahead of Time?

Absolutely!

This is one of the reasons I love it for busy weeknights.

Assemble the casserole according to the recipe, but don't bake it yet.

Cover it tightly and refrigerate for up to 24 hours.

When you're ready to bake, remove it from the refrigerator while the oven preheats.

Because the casserole is starting cold, it may need additional baking time.

Make sure the center is thoroughly hot before serving.

Can I Use Rotisserie Chicken?

Yes!

In fact, rotisserie chicken is one of the easiest ways to make this recipe.

Remove the skin and bones, then shred or chop the meat.

You can use both white and dark meat.

The combination gives the casserole plenty of flavor.

What to Serve With Chicken Broccoli Rice Casserole

This casserole is already a complete meal for many families, so you don't need much alongside it.

But if you'd like to add a side, try:

  • Simple green salad
  • Garlic bread
  • Dinner rolls
  • Roasted carrots
  • Green beans
  • Fresh fruit
  • Steamed vegetables

A crisp salad is especially nice because it adds freshness to the creamy casserole.

How to Store Leftovers

Allow the casserole to cool, then transfer leftovers to an airtight container or cover the baking dish tightly.

Refrigerate for 3–4 days.

When reheating, add a small splash of milk or chicken broth if the casserole seems dry.

Warm individual portions in the microwave, or reheat larger amounts covered in the oven.

Can You Freeze Chicken Broccoli Rice Casserole?

Yes, but the texture may change slightly after freezing because of the creamy sauce and broccoli.

For best results, allow the casserole to cool completely before freezing.

Wrap it tightly and place it in a freezer-safe container.

Freeze for up to 2–3 months for best quality.

Thaw overnight in the refrigerator before reheating.

If you're specifically preparing this casserole for the freezer, consider slightly undercooking the broccoli so it doesn't become overly soft after reheating.

Can I make this without cream of chicken soup?

Cheddar, Monterey Jack, Colby Jack, mozzarella, and pepper Jack are all delicious choices.

How do I make the top extra crispy?

Add a buttery cracker topping and finish the casserole uncovered.
