Ingredients You’ll Need

Each ingredient in this Creamy Chicken Broccoli Rice Casserole Recipe is handpicked to add layers of flavor and texture. The creamy cheeses and spices blend perfectly with tender chicken and fresh broccoli, and a heads-up: using good-quality cheese here genuinely makes a difference.

Unsalted butter: For sautéing the chicken and building a rich base flavor without added salt.
Chicken thighs: Juicy, tender, and flavorful—thighs remain moist even after baking.
Olive oil: A bit of oil helps brown the chicken nicely and deepen flavor.
Garlic cloves (minced): Fresh garlic is a must for that fragrant, savory punch.
Chicken stock: Adds savory depth and moisture to the casserole base.
Cream of chicken with herbs (canned): This is the creamy binder that brings everything together with herby goodness.
Heavy cream: Use it to top off the cream of chicken for an ultra-rich sauce that coats every bite.
Cheddar cheese (mild or medium): Melted cheese makes this dish indulgent and gives it that golden, bubbly crust.
Sour cream: Adds tang and velvety texture for balanced richness.
Boursin cheese: This herby, creamy cheese adds a subtle gourmet twist that’s so worth it.
Bayou City All Purpose seasoning (divided): This spice blend amps up the savory notes; use it carefully to balance heat and flavor.
Bayou City garlic pepper: A punchy seasoning that complements the garlic used elsewhere.
Onion powder: For a mild sweet onion flavor that blends subtly in the background.
Cayenne pepper: Just a little kick here wakes up the richness without overwhelming.
Broccoli florets (cooked): Fresh or steamed broccoli adds a lovely crunch and vibrant green color.
White rice (cooked): The hearty starch that pulls everything together in this filling casserole.
Salt and pepper: To taste — always taste as you go to get this perfect!

Variations

Believe me, this Creamy Chicken Broccoli Rice Casserole Recipe is like a warm canvas for your own twists. I often tweak it to suit whatever I’m craving or what I have on hand, and you should feel free to do the same!

Add mushrooms or bell peppers: I love throwing in some sautéed mushrooms for extra earthiness or diced bell peppers for a pop of sweetness and color.
Use brown rice instead of white: For a nuttier flavor and a bit more fiber, swap in brown rice—just make sure it’s fully cooked first.
Skip the heavy cream and use Greek yogurt: If you want a lighter but still creamy casserole, Greek yogurt works well in place of cream, just fold it in gently.
Make it spicier: I sometimes double the cayenne or add a dash of hot sauce to give it a bold kick.
Go vegetarian: Swap chicken thighs for firm tofu or extra veggies like cauliflower or zucchini to keep that creamy vibe meat-free.

How to Make Creamy Chicken Broccoli Rice Casserole Recipe

Step 1: Sear the chicken thighs until golden and juicy

Start by heating your butter and olive oil in a large skillet over medium-high heat. Once hot, add the chicken thighs seasoned lightly with salt, pepper, and a touch of the Bayou City All Purpose seasoning from the list. Sear each side until beautifully golden—this usually takes about 4-5 minutes per side. Don’t rush this part; browning develops flavor and keeps the chicken moist later. Once done, remove the chicken and set aside.

Step 2: Build the creamy sauce with garlic and seasonings

In the same skillet, lower the heat to medium and add minced garlic, cooking until fragrant—about 30 seconds, don’t let it burn. Pour in the chicken stock and stir, scraping up those golden bits from the pan. Mix the canned cream of chicken with heavy cream to fill the same can, then add that creamy goodness to the skillet. Stir in the sour cream, Boursin cheese, spices including garlic pepper, onion powder, cayenne, and the rest of your Bayou City seasoning. Let this sauce simmer gently until it’s smooth and slightly thickened. Taste and adjust salt or pepper as needed.

Step 3: Assemble with rice, broccoli, cheese, and chicken

Preheat your oven to 350°F (175°C). In a large mixing bowl, combine your cooked white rice and steamed broccoli florets. Pour the creamy sauce over the rice and broccoli, folding it until everything is well coated. Then add shredded cheddar cheese—reserve a handful for topping later. Gently fold in the seared chicken thighs, breaking them into bite-sized pieces if you want easier serving. Pour this mixture into a greased casserole dish, spreading it out evenly. Sprinkle the remaining cheddar cheese on top to get that irresistible baked crust.

Step 4: Bake until bubbly and golden

Pop the casserole into your preheated oven and bake for 25-30 minutes, or until it’s bubbly around the edges and the cheese on top is melted and lightly browned. A foil tent over the casserole early on can help if your cheese browns too fast. Once out of the oven, let it rest for about 5 minutes before serving. This helps everything set and makes serving easier.

Garnishes

I love sprinkling fresh chopped parsley or green onions over the top right before serving—it cuts through the richness with a pop of freshness and color. Sometimes I’ll add a little extra cracked black pepper for a subtle bite that complements the creaminess perfectly.

Side Dishes

This casserole is pretty hearty on its own, but when I want some extra greens, I serve it alongside a crisp green salad with a zesty vinaigrette or roasted root vegetables. A simple cucumber tomato salad also pairs beautifully, adding brightness and texture contrast.

Creative Ways to Present

For special occasions, I sometimes bake this casserole in individual ramekins for personalized servings—everyone loves that! Another fun trick is topping each serving with a sprinkle of extra cheddar and broiling it for a couple of minutes to get a golden bubbly crust that feels totally gourmet.

Make Ahead and Storage

Storing Leftovers

I store leftovers in airtight containers in the fridge, and it usually keeps beautifully for 3 to 4 days. Before putting it away, I make sure the casserole is completely cooled to prevent sogginess. Leftovers taste fantastic the next day—as if the flavors have even had more time to marry!

Freezing

I’ve found this Creamy Chicken Broccoli Rice Casserole Recipe freezes really well. Just portion it out into freezer-safe containers or wrap the whole casserole tightly with plastic wrap and foil. It can last up to 3 months frozen—perfect for prepping meals ahead or quick dinners on busy nights.

Reheating

When reheating, I like to thaw it in the fridge overnight first. Then, heat it in the oven at 325°F (160°C) covered with foil to keep moisture, removing the foil at the end to re-crisp the top. If you’re in a time crunch, microwave reheats fine too—just cover loosely, stir once partway through, and watch so it doesn’t dry out.

FAQs

Can I use chicken breasts instead of thighs for this casserole?

Absolutely! Chicken breasts work fine, though they tend to be leaner and can dry out if overcooked. To keep them juicy, sear them gently and consider cutting into smaller pieces so they cook evenly within the casserole.
What’s the best way to cook broccoli for this casserole?

I usually steam the broccoli until just tender but still bright green and a little firm—about 4-5 minutes. This prevents it from turning mushy during baking and keeps a nice texture contrast in the casserole.
Can I make this casserole ahead of time and refrigerate before baking?

Yes! Assemble the casserole, cover tightly with foil or plastic wrap, and refrigerate for up to 24 hours before baking. When ready, bake as directed, just add a few extra minutes if it’s cold from the fridge.
How do I make this dish dairy-free?

To make a dairy-free version, use coconut cream or a dairy-free cream alternative instead of heavy cream and sour cream, and choose a dairy-free cheese or omit cheese altogether. The casserole will be less creamy but still tasty!
What’s the best rice to use for this recipe?

White rice is the classic choice here for its fluffy texture, but you can use brown rice or even jasmine for a fragrant twist. Just make sure your rice is fully cooked and cooled before mixing it into the casserole to avoid mushiness.
