Chicken Broccoli Rice Casserole

Perfectly seasoned chicken comes together with tender broccoli and rice enveloped in a creamy, cheesy sauce. Both kids and adults love this recipe and are quick to devour it. Aside from having all the food groups in one skillet (a huge win), it’s also filling and a money-saver. And did I mention it’s freezer-friendly? We have so much to love about throwing this super easy chicken broccoli rice casserole in the oven. 💞

Ingredient List

How to Make Chicken, Rice, and Broccoli Casserole

Prep the Ingredients

Preheat the oven to 350℉ (175℃). Season the chicken cubes with salt, followed by salt-free Cajun Creole seasoning. Stir until thoroughly seasoned. Heat oil in a skillet. Then, add the chicken, cooking for 3-5 minutes. (Photo 1) Saute Aromatics – Next, add the minced garlic and stir for about a minute, followed by the chopped onion. Cook until onions wilt, for about 4 more minutes. Remove them from the pan and set aside. Roux – In a 10-inch oven-safe skillet, add the butter. Whisk in the flour as soon as the butter melts. Continue whisking until the butter fully absorbs the flour, then cook for about a minute. (Photo 2) Sauce – Slowly add the chicken broth while whisking, and follow with the milk. Bring it to a boil, then turn the heat down to medium-low so it simmers gently and thickens into a cream sauce. It takes 6-8 minutes. (Photo 3)

Bake

Assemble – Turn off the heat and stir in the chicken, rice, broccoli, and ½ cup cheese. Stir well, then add Creole seasoning and salt. Adjust seasonings to your liking, then top with the remaining cheese. (Photos 4-5) Bake, uncovered, at 350℉ (175℃) for 15-30 minutes or until heated through. (Photo 6) Serve – Allow the casserole to rest for 5-10 minutes so no one burns their mouth on the cheese, and then serve hot.

Notes & Tips

Make-Ahead Instructions

Cook this in a big batch in advance, let it cool, and then transfer it to a freezer-safe dish. Cover it tightly and freeze. Thaw it overnight in the fridge so you can reheat it for lunches and dinners throughout the week. You can also assemble this dish, but hold off baking it until the next day. Then pop it in the oven for about 30 minutes when you’re ready to serve it. 😅

Serving and Storage Instructions

Serve chicken broccoli rice casserole hot, fresh out of the oven. Refrigerate leftover casserole for 3-5 days in an airtight container. Reheat them in the oven set to 350℉ (175℃) until warmed through or in the microwave.

What Goes With Chicken Broccoli Rice Casserole

I like to serve this casserole with pull-apart garlic bread rolls and a quick wedge salad. Complete your meal with some sweet tea to drink and sweet potato pie for dessert. 😋
