Ingredients

  • 1 pound chicken breasts, cut into bite sized cubes
  • 2 cups brown rice, cooked
  • 6 cups fresh broccoli, cut into small florets

For The Sauce

  • 2 tablespoons olive oil, divided
  • 1 small onion, diced
  • 2 tablespoons gluten free flour
  • 2 cups milk
  • ¼ teaspoon garlic powder
  • ¼ teaspoon onion powder
  • ½ teaspoon dry mustard powder
  • ½ teaspoon smoked paprika
  • ½ teaspoon kosher salt, or to taste
  • ¼ teaspoon ground pepper
  • 2 cups cheddar cheese, shredded and divided
  • 2 tablespoons curly parsley, freshly chopped to garnish

Step By Step Instructions

Step 1: Prepare The Chicken

First things first, preheat your oven to 400°F. Grab your bite sized chicken pieces and season them with a little salt and pepper. Drizzle with one tablespoon of olive oil.

Toss everything to make sure the chicken is coated well. Then, arrange it in a single layer in your casserole dish. This helps it cook evenly. Pop it in the oven for 10 minutes.

Step 2: Make The Creamy Sauce

While the chicken is getting a head start, let’s make that amazing cheese sauce. Heat the remaining tablespoon of oil in a skillet. Add the diced onion and sauté until it’s soft.

Next, sprinkle in the flour and whisk it for about a minute. Carefully pour in the milk, whisking constantly to keep it smooth. Nobody wants lumpy sauce!

As it begins to bubble, add the garlic powder, onion powder, mustard powder, paprika, salt, and pepper. Let it simmer on low until it gets thick and bubbly.

Remove the skillet from the heat. Now for the best part. Stir in one and a half cups of the shredded cheddar cheese. Whisk until it is completely melted and oh so creamy.

Step 3: Assemble The Casserole

Carefully take the casserole dish out of the oven. Add your cooked brown rice over the chicken, followed by the fresh broccoli florets. Now, pour that glorious cheese sauce all over everything.

Gently toss it all together to make sure everything is nicely coated in the sauce. This ensures every bite of your Chicken Rice Broccoli Casserole Bake is delicious.

Step 4: Bake To Perfection

Sprinkle the last half cup of cheese over the top. It is time to bake! Place it back in the oven for 20 more minutes.

You will know it is ready when the broccoli is tender and the cheese on top is golden brown and bubbling. That sight is pure happiness.

Let it cool for a moment, then garnish with fresh parsley before serving it warm.

How To Store Leftovers

Got leftovers? Lucky you! Storing this casserole is simple. You can wrap the dish in foil or transfer the contents to an airtight container.

It will keep well in the fridge for up to 3 or 4 days. The flavors often get even better the next day, making for a fantastic lunch.

Tips

For the best results, have your brown rice cooked before you start. It makes the whole process go much smoother.

When preparing the broccoli, try to cut the florets into similar sizes. This helps them cook at the same rate. You can also buy precut florets to save some time.

Don’t be afraid to switch up the cheese! While cheddar is a classic, mozzarella or a Colby blend would also be wonderful in this dish.

Conclusion

And there you have it! A simple, comforting, and delicious Healthy Chicken Broccoli Rice Casserole Bake that is sure to become a family favorite.

It is the perfect meal for a busy weeknight when you want something satisfying without a lot of fuss. Enjoy every cheesy, flavorful bite!
