Why You’ll Love This Chicken Broccoli Rice Casserole

This casserole is everything you want in a one-dish meal: simple, filling, and full of flavor. It uses real ingredients—no canned soup required—and still delivers that creamy texture everyone expects. It’s perfect for sneaking in some vegetables (hi, broccoli!) and the leftovers reheat beautifully.

Whether you’re cooking for a family or just want an easy meal to enjoy over a couple of days, this recipe has your back. It’s budget-friendly, freezer-friendly, and honestly just delicious.

What Kind of Rice Should I Use?

Long grain white rice works best here because it holds its texture without turning mushy. Jasmine or basmati rice both do well, too. If you prefer brown rice for added nutrition, just be sure to par-cook it first since it takes longer to soften. Avoid instant rice—it tends to overcook and lose structure in the oven.

Options for Substitutions

If you’re out of broccoli or want to mix things up, feel free to use cauliflower, peas, or even green beans. For a vegetarian version, skip the chicken and add mushrooms or chickpeas. Cheddar cheese is classic, but Monterey Jack, Swiss, or a mix of your favorites work great, too.

You can also swap in quinoa or couscous for the rice, just adjust the cooking time accordingly. And if you’re going low-dairy, use plant-based cheese and a dairy-free béchamel for the same creamy goodness.

Ingredients for this Chicken Broccoli Rice Casserole

Cooked chicken – The protein base for this casserole. Rotisserie chicken or leftover roasted chicken both work well.
Broccoli florets – Adds color, crunch, and nutrition. Use fresh or frozen (thawed) broccoli.
White rice – Long grain rice is ideal for its fluffy texture. Pre-cooked rice saves time.
Sharp cheddar cheese – For that golden, gooey top and rich cheesy flavor.
Milk – Adds creaminess and helps bind the sauce. Whole milk is preferred for richness.
Butter – Adds depth and helps create the creamy base.
Flour – For thickening the milk into a smooth sauce (this replaces canned soup).
Onion and garlic – Essential aromatics that build flavor from the base.
Salt, pepper, and paprika – Basic seasoning to bring everything together.

Step 1: Cook the Chicken (if not using pre-cooked)

If you’re not using rotisserie or leftover chicken, start by seasoning boneless, skinless chicken breasts with salt and pepper. Cook in a skillet over medium heat until golden and fully cooked through. Let it rest before shredding or dicing into bite-size pieces.

Step 2: Prepare the Sauce

In a saucepan, melt the butter over medium heat. Add chopped onion and garlic and cook until softened. Whisk in the flour and cook for 1-2 minutes to eliminate the raw taste. Slowly pour in the milk, whisking continuously, until the sauce thickens. Season with salt, pepper, and paprika.

Step 3: Steam the Broccoli

Lightly steam the broccoli until just tender and still bright green. This prevents overcooking in the oven. If using frozen broccoli, thaw and pat dry to avoid excess moisture.

Step 4: Mix Everything Together

In a large mixing bowl, combine the cooked rice, shredded chicken, steamed broccoli, half of the shredded cheddar, and the creamy sauce. Stir until everything is evenly coated.

Step 5: Assemble the Casserole

Pour the mixture into a greased 9×13-inch baking dish. Spread it out evenly and sprinkle the remaining cheddar cheese over the top.

Step 6: Bake to Perfection

Preheat your oven to 375°F (190°C). Bake the casserole uncovered for 25-30 minutes, or until the cheese is bubbling and golden on top. For a crispier top, broil for the last 2 minutes.

Step 7: Let It Rest

Once baked, allow the casserole to sit for about 5 minutes before serving. This helps the layers set and makes serving easier.

How Long to Prepare the Chicken Broccoli Rice Casserole

Prep Time: If you’re using pre-cooked chicken and pre-cooked rice, the prep is incredibly quick—about 15-20 minutes. That includes steaming the broccoli, making the sauce from scratch, and combining the ingredients.

Bake Time: Once assembled, the casserole needs around 25-30 minutes in a 375°F oven until the cheese is bubbling and slightly golden. Total time from start to finish is approximately 45 minutes, making it a solid weeknight dinner option.

Tips for Perfect Chicken Broccoli Rice Casserole

Use freshly shredded cheese for better melting and flavor—pre-shredded cheese often contains anti-caking agents.
Don’t overcook the broccoli before baking; it will continue to soften in the oven.
Taste your sauce before mixing—it’s the best time to adjust seasoning.
Let the casserole sit for 5 minutes after baking to help it set and slice better.
Add a touch of Dijon mustard to the sauce for extra depth and zing.

Watch Out for These Mistakes While Cooking

Using raw rice—always pre-cook your rice to avoid a crunchy casserole.
Adding too much liquid—this can make the casserole soggy. Stick to the measurements.
Skipping the thickening step—undercooked roux will lead to a watery base.
Overloading with cheese—while tempting, too much cheese can overpower the balance of flavors.
Not preheating the oven—this ensures even baking from the start.

What to Serve With Chicken Broccoli Rice Casserole?

1. Garlic Bread

Crunchy, buttery garlic bread is perfect for scooping up creamy bites of the casserole.

2. Crisp Green Salad

A simple salad with vinaigrette balances the richness of the casserole.

3. Roasted Carrots

Sweet, caramelized roasted carrots add a lovely contrast and color.

4. Sautéed Green Beans

Lightly sautéed green beans with lemon zest pair nicely for added freshness.

5. Apple Walnut Salad

For something a bit more special, this salad adds texture and a sweet note.
