Ingredients & Notes
- Chicken - I highly recommend using breasts for this chicken fajita casserole as they absorb the flavor of the rest of the ingredients well. An easy way to pull chicken is to boil it in water and shred it in a stand mixer using a beater attachment while it’s still warm.
- Veggies - A combination of red and green bell peppers and white onion adds lots of color along with vitamins and nutrients to keep you full.
- Taco seasoning - I used a store-bought packet, but you can easily make your own too! You will need 3 - 4 tablespoons if you do.
- Instant brown rice - I like to use brown rice in place of white rice whenever I can for extra nutrients and fiber, and Instant varieties make it super quick! White rice will also work well with this fajita casserole if that’s what you prefer. However, you will likely need to adjust the amount of broth used.
- Broth - Any type will work. I chicken broth, but vegetable broth will be just as tasty. Use reduced-sodium to decrease the amount of salt in the dish.
- Greek yogurt (not pictured)- Used to provide the same tangy flavor and creamy texture as sour cream with less fat and more protein. If needed, you could swap it out for a dairy-free yogurt.
- Cheese - I use a fresh Mexican blend but any cheese will work in this recipe. Feel free to use a dairy-free option, too.
- Tortillas - Served alongside the finished chicken fajita casserole, these are the final touch to make it a show-stopping meal. Feel free to stuff, dip, shred them, or, omit them completely.
Made with all the flavor of classic chicken fajitas and none of the fuss, this casserole is a pretty failproof dish! All you’ll need is a 9x13 baking dish, and it will be ready in no time.
Step 1 : Prepare the chicken and vegetables. Pull or shred the chicken if you haven’t already. Then, add it to a baking dish along with the peppers and onions. Sprinkle the taco seasoning on top, and toss to coat.
Step 2 : Add the remaining ingredients. Combine the brown rice, chicken broth, Greek yogurt, and cheese with the chicken and vegetables, tossing until everything is well distributed.
Step 3 : Bake. Place the baking dish in the oven uncovered. Then, stir the casserole, add the remaining cheese, and place it back in the oven until the vegetables are tender and the cheese has melted. Broil for a few extra minutes to achieve a beautiful golden top layer of cheese.
Step 4: Serve. Serve your chicken fajita casserole warm with a side of heated tortillas, and enjoy!
- Toss the vegetables really well with the taco seasoning. This is how the entire dish is flavored!
- Be sure to stir the rice into the dish so that the broth is covering the rice. The rice cooks into the broth and will absorb the liquid.
- Give the entire casserole a big stir after the first 15 minutes of cooking. This will ensure the rice is getting well cooked and the cheese is distributed evenly.
How to Serve Chicken Fajita Casserole
There are so many ways to serve this chicken fajita casserole!

How to Store
This chicken fajita casserole stores really well. Simply let it cool down completely. Then, cover it with aluminum foil or an airtight lid, and keep it in the refrigerator for up to 3 days. Heat it back up in the microwave in 30-second increments or in the oven at 300 for 5 - 10 minutes until your desired temperature is reached.
Can I Make This Ahead of Time
To prepare this chicken fajita casserole ahead of time, add all the ingredients to a baking dish except the broth, yogurt, and cheese. Cover in the fridge until you’re ready to make the dish.
When ready to cook, stir in the broth, yogurt, and cheese, and bake as directed.
If you want to make this dish and freeze it, prepare it as directed. Then, cook it for just 15 minutes, and let it cool completely before storing it in a freezer-friendly container. When ready to serve, let the fajita casserole thaw out on the counter for at least 2 hours. Sprinkle a layer of shredded cheese over top, and bake for 15 minutes at 350 F until the cheese has melted.
