Ingredients Needed to Make Creamy Chicken Broccoli Rice Cheese Casserole

When it comes to making Creamy Chicken Broccoli Rice Cheese Casserole, the magic lies in simple ingredients that come together for a comforting, crowd-pleasing dish. Most of these are pantry or fridge staples, which is why this casserole is such a weeknight favorite. Here’s a closer look at what you’ll need and why each ingredient matters.

• Cooked Chicken (2 cups, diced): This is the protein powerhouse of the casserole. You can use leftover roasted chicken, shredded rotisserie chicken, or even poached chicken breasts. Rotisserie chicken is my go-to for busy nights since it adds flavor and cuts down prep time. If you loved using chicken in my Creamy Chicken Enchilada Soup, you’ll appreciate how it works just as well here.
• Broccoli Florets (2 cups): The bright green crunch balances all the cheesy creaminess. Fresh broccoli is best for texture, but frozen florets work too—just thaw and pat them dry so they don’t water down your casserole. If you have picky eaters, chopping them into smaller bites helps hide the veggies in all that creamy goodness.
• Cooked Rice (2 cups): Rice acts as the hearty base, soaking up the creamy sauce while keeping the casserole filling. Long-grain white rice gives the lightest texture, but brown rice adds more fiber and a nuttier flavor. Make sure the rice isn’t mushy before baking—it’ll soften as the casserole bakes.
• Shredded Cheddar Cheese (2 cups): The star of any cheesy casserole. Sharp cheddar adds a bolder flavor, while mild cheddar melts smoothly. For extra gooeyness, mix in mozzarella. If you’re a fan of melty, cheesy recipes like my Tiktok Lasagna Soup, you’ll love how the cheddar pulls everything together here.
• Cream of Chicken Soup (10.5 oz can): This shortcut ingredient creates the creamy backbone of the casserole. It blends beautifully with the sour cream and spices to coat every grain of rice and piece of chicken. You can swap in cream of mushroom or cream of celery soup if that’s what you have on hand.
• Milk (½ cup): A splash of milk lightens up the sauce, helping it spread evenly through the dish without becoming too thick or heavy. Whole milk gives the richest flavor, but 2% works fine if that’s what’s in the fridge.
• Sour Cream (¼ cup): This adds tanginess and depth to the creamy sauce, keeping it from feeling too heavy. Greek yogurt is a good substitute if you want something lighter but still creamy.
• Garlic Powder (1 tsp): A little seasoning goes a long way. Garlic powder enhances the chicken’s flavor and blends seamlessly into the creamy base without overpowering it.
• Onion Powder (1 tsp): Paired with the garlic powder, onion powder adds savory depth that makes the casserole taste like it simmered all day.
• Salt (½ tsp) and Black Pepper (¼ tsp): These simple seasonings bring out the best in every ingredient. Don’t skip them, especially since cheese and soup alone can’t fully season the dish.
• Crispy Fried Onions (½ cup, optional): If you want crunch and extra flavor, sprinkle these on top in the last few minutes of baking. They turn this casserole from cozy to downright irresistible.

Together, these ingredients make the Creamy Chicken Broccoli Rice Cheese Casserole not only hearty but also well-rounded. Protein, vegetables, carbs, and cheese—all baked into one dish.

Instructions to Make Creamy Chicken Broccoli Rice Cheese Casserole

Making Creamy Chicken Broccoli Rice Cheese Casserole is easier than it looks, and the payoff is a bubbling, golden dish that feels like home. Follow these step-by-step instructions for the best results:

Step 1: Preheat the Oven

Set your oven to 375°F (190°C). Preheating is important so the casserole cooks evenly from the start. If you put it into a cold oven, the cheese won’t melt properly, and the sauce may separate. Grease a 9×13-inch baking dish with butter or cooking spray—this keeps the casserole from sticking and makes cleanup much easier.

Step 2: Combine the Base Ingredients

In a large mixing bowl, stir together the diced cooked chicken, fresh broccoli florets, and cooked rice. This step ensures every bite of the casserole has a mix of protein, veggies, and grains. If you’ve tried my Southwest Chicken Soup, you know how important it is to balance flavors from the very beginning.

Step 3: Whisk the Creamy Sauce

In a separate bowl, whisk together the cream of chicken soup, milk, sour cream, garlic powder, onion powder, salt, and pepper. This mixture is the heart of the casserole—it ties everything together with a rich, velvety texture. Pro tip: whisk until smooth to avoid lumps. If you want more depth, a dash of paprika or Italian seasoning works wonders here.

Step 4: Combine Everything with Cheese

Pour the creamy sauce over the chicken, broccoli, and rice mixture. Add 1 ½ cups of shredded cheddar cheese at this stage and fold everything gently. This step makes sure every grain of rice and bite of chicken gets coated in creamy, cheesy goodness. If you’re a fan of cheesy comfort recipes like my Skillet Chili Cornbread Pot Pie, this step will feel familiar.

Step 5: Transfer to Baking Dish

Spoon the mixture into the greased baking dish. Spread it evenly so it bakes consistently. Press lightly with a spatula to settle everything—no one wants a bite that’s just rice without the cream and cheese!

Step 6: Add the Cheesy Topping

Sprinkle the remaining ½ cup of cheddar cheese over the top. This creates that gooey, golden layer everyone fights over at the dinner table. If you’re craving an extra crunch, hold off and add crispy fried onions in the final minutes of baking.

Step 7: Bake to Perfection

Place the dish in the preheated oven and bake for 25–30 minutes, until the cheese on top is melted, bubbling, and slightly golden. The aroma filling your kitchen at this point is your signal that comfort food is minutes away.

Step 8: Optional Crunchy Finish

If you’re using crispy fried onions, sprinkle them over the casserole during the last 5 minutes of baking. This keeps them crunchy instead of soggy. They add a delicious oniony bite and a texture that contrasts the creaminess underneath.

Step 9: Rest Before Serving

Remove the casserole from the oven and let it rest for 5–10 minutes. This step is crucial—it allows the sauce to set and keeps the slices neat when serving. Skipping this rest period can leave you with a runny casserole.

Serving Suggestion

Once rested, scoop generous portions of your Creamy Chicken Broccoli Rice Cheese Casserole onto plates. Pair it with a side salad, garlic bread, or even a light soup like Italian Orzo Spinach Soup to round out the meal.

What to Serve with Creamy Chicken Broccoli Rice Cheese Casserole

This casserole is a meal on its own, but if you’re feeding guests or want to round things out, pair it with a crisp garden salad or roasted veggies for extra color. Garlic bread or homemade rolls are perfect for soaking up the creamy sauce. If you’d like a soup starter, try something lighter like Italian Orzo Spinach Soup to balance the richness. For drinks, iced tea or a light white wine keeps things refreshing. And let’s be honest—if dessert follows, something fruity like apple crisp is the perfect sweet finish.

Key Tips for Making Creamy Chicken Broccoli Rice Cheese Casserole

Use rotisserie chicken for a time-saving hack—it adds flavor and cuts prep in half. If you’re cooking rice fresh, make it slightly underdone since it’ll soften while baking. Fresh broccoli gives a nice bite, but frozen works too—just thaw and pat dry so your casserole doesn’t get watery. Don’t skimp on the resting time after baking; it lets the sauce set. And if you want a little crunch, top with buttery breadcrumbs or fried onions. For a flavor twist, try mixing in a little parmesan or swapping cheddar for pepper jack to add a kick.

Storage and Reheating Tips for Creamy Chicken Broccoli Rice Cheese Casserole

Leftovers store beautifully, making this casserole a meal-prep superstar. Once cooled, cover tightly and refrigerate for up to 4 days. To freeze, portion into airtight containers—reheating individual servings is easier than defrosting the whole pan. Reheat in the oven at 350°F until warmed through (about 20 minutes), or microwave in 1-minute bursts, stirring to keep the sauce creamy. Add a splash of milk before reheating if it seems dry. Pro tip: freeze without the fried onion topping and add it fresh when reheating so it stays crisp.
