Cheesy Broccoli Chicken and Rice Casserole

This is my go-to broccoli chicken rice casserole recipe, and it never lets me down.

This is the casserole that shows up in nearly every family’s regular rotation, chicken, broccoli, and rice baked together in a rich cheese sauce. This version builds that sauce from scratch rather than relying on canned soup, and the difference in flavor is genuinely worth the few extra minutes.

This has become my go-to comfort food dinner, the kind of meal that feeds a family easily and reheats beautifully the next day.

Why You’ll Love This Recipe

A few reasons this casserole earns its classic status.

Genuinely comforting: a true family dinner staple.
Homemade cheese sauce: real flavor, not from a can.
Feeds a crowd: a full 9×13 pan goes a long way.
Great for leftovers: reheats beautifully.

Why This Works

Building a proper roux-based cheese sauce, butter and flour cooked together before the milk and cheese go in, is what gives this casserole a genuinely smooth, rich sauce instead of the thinner, more processed taste of canned soup. That roux thickens the sauce properly and lets the real cheese flavor come through clearly.

Step-by-Step

Cook the rice according to package directions. Steam or blanch the broccoli florets until just tender-crisp, then set aside.

 

Melt butter in a saucepan and whisk in flour to form a paste, cooking for a minute. Gradually whisk in milk until smooth, then simmer until thickened. Stir in shredded cheddar until melted.

Combine the cooked rice, broccoli, diced cooked chicken, and cheese sauce in a large bowl, mixing until everything is evenly coated. Spread into a greased baking dish.

 

Top with extra shredded cheddar and bake at 350 degrees for 20 to 25 minutes, until bubbling and golden. Let it rest for a few minutes before serving.

Tips

• Build the cheese sauce with a proper roux, this gives it a genuinely smooth, rich texture.
• Don’t overcook the broccoli before baking, it softens further in the oven.
• Use rotisserie chicken to save time.
• Let the casserole rest before serving so it holds together when scooped.
• Use freshly shredded cheese for the smoothest sauce.

Variations

• Add sautéed mushrooms.
• Use a mix of cheddar and mozzarella.
• Add a breadcrumb topping for extra crunch.
• Swap broccoli for cauliflower.

What to Serve With

• A simple side salad.
• Dinner rolls.
• Steamed carrots.
• A glass of white wine.

Storage

Refrigerator: store in an airtight container for up to 4 days.

Freezer: freeze in a freezer-safe dish for up to 2 months.

Reheating: reheat covered in the oven at 350 degrees until warmed through, or microwave individual portions.

Make Ahead

This casserole can be assembled a day ahead and refrigerated unbaked, then baked fresh, adding a few extra minutes to the bake time.

Frequently Asked Questions

Can I use frozen broccoli?

Yes, thaw and drain it well first to avoid adding excess water to the casserole.

Can I make this ahead and freeze it?

Yes, assemble it fully, cover tightly, and freeze unbaked, then thaw overnight before baking as directed.

Why is my cheese sauce grainy?

The cheese was likely added over too high heat, keep the temperature moderate when melting it into the sauce.

Final Thoughts

This casserole proves a homemade cheese sauce genuinely makes a real difference over the canned version. Give it a try for your next family dinner.
