How to Make Easy Chicken Fajita Rice Casserole

Step 1: Sauté the Veggies

Get started by heating a generous swirl of olive oil in a large skillet over medium heat. Add your sliced onions and all three bell peppers; sauté until they’re soft, fragrant, and just starting to caramelize at the edges. This quick step brings out their natural sweetness and is the secret to achieving that classic fajita vibe in our casserole.

Step 2: Prepare the Chicken

While the veggies are cooling, toss your chicken pieces with a hearty sprinkle of fajita seasoning. Using the same skillet (no need to wash—one less dish!), sear the seasoned chicken until it’s beautifully browned on both sides. This locks in flavor and gives the meat a lovely, slightly crispy edge. Once done, cut the chicken into bite-sized pieces to make serving a breeze.

Step 3: Combine Everything in a Casserole Dish

Now it’s time to pull out your trusty 9×13-inch baking dish. Give it a quick spray or a light buttering. Spread the uncooked rice along the bottom for the perfect base, then pour in the chicken broth to pre-season every grain. Layer in your golden-brown chicken and sautéed veggies, and if you’re using black beans, corn, or diced tomatoes, now’s their moment to shine. Give everything a gentle stir to mingle all those delicious flavors.

Step 4: Bake to Perfection

Tightly cover your casserole dish with foil and let it bake in a 375°F (190°C) oven for 35–40 minutes. The rice will soak up every drop of broth, and the chicken will become tender all the way through. The aroma at this stage will seriously test your patience!

Step 5: Add Cheese and Finish Baking

For the grand finale, pull off the foil and shower the top with a generous layer of shredded cheese. a few more minutes in the oven until it’s melted, golden, and irresistibly bubbly, and your Easy Chicken Fajita Rice Casserole is ready to serve up hot and happy at your table.

Side Dishes

Make Ahead and Storage

Storing Leftovers

Leftovers hold up beautifully in the fridge, making this Easy Chicken Fajita Rice Casserole just as perfect for lunch the next day. Cool the casserole completely, then transfer to an airtight container and enjoy within 3 to 4 days for the best flavor and texture.

Freezing

If you want to squirrel some away for later, this casserole freezes surprisingly well. Make sure it’s fully cooled, then pack it into a freezer-safe dish or individual containers. Freeze for up to 2 months; just remember to label and date so you don’t forget what deliciousness awaits!

Reheating

When it’s time to dive in again, reheat the casserole in the oven at 350°F (175°C), loosely covered with foil, until hot throughout (usually about 20 minutes). Or, for a speedy option, zap individual servings in the microwave in a covered bowl for a couple of minutes until steaming.

FAQs

Can I make Easy Chicken Fajita Rice Casserole ahead of time?

Absolutely! Assemble the casserole right up to the final cheese layer, then cover and refrigerate overnight. When you’re ready, bake as directed (adding an extra 5–10 minutes if baking straight from the fridge), then add cheese near the end for a just-melted finish.

Is this casserole spicy?

It’s as mild or spicy as you want it! Most fajita seasoning packets are pretty mild, but if you love extra heat, toss in some sliced jalapeños, a pinch of cayenne, or a splash of your favorite hot sauce before baking.

Can I use leftover cooked chicken?

Definitely. Stir in chopped cooked chicken after the rice and broth are added, skipping the chicken-searing step. This is a great way to use up rotisserie chicken and still bask in all the Easy Chicken Fajita Rice Casserole flavors.

What type of rice works best?

Long-grain white or brown rice is ideal and ensures the right texture. Avoid quick-cooking or instant rice, which can end up mushy. If you’re using brown rice, just allow a little extra baking time until tender.

Can I make this vegetarian?

Of course! Simply leave out the chicken and double up on the black beans and corn for a plant-powered version that’s just as hearty and full of bold fajita flavors.
