Ingredients
Prep Time: 15 minutes
Cook Time: 30 minutes
Total Time: 45 minutes
Servings: 6
- 1 lb chicken breast, diced
- 1 bell pepper, sliced
- 1 onion, sliced
- 2 cups cooked rice
- 1 can black beans, drained and rinsed
- 1 can diced tomatoes with green chilies
- 1 tablespoon fajita seasoning
- 1 cup shredded cheese
- Salt and pepper to taste
- Olive oil

Step-by-Step Instructions
1. Preheat your oven to 350°F (175°C).
2. In a large skillet, heat a drizzle of olive oil over medium heat. Once the oil shimmers, add the diced chicken. Sauté for about 5 minutes or until the chicken is browned and cooked through. Make sure to stir occasionally for even cooking. Next, add the sliced bell pepper and onion to the skillet, cooking for an additional 5-7 minutes until the vegetables are tender.
3. Once the vegetables are cooked, stir in the cooked rice, drained black beans, diced tomatoes with green chilies, and fajita seasoning. Mix everything together until well combined. This mixture forms the flavorful base of your casserole.
4. Transfer the chicken and rice mixture to a greased casserole dish. Spread it out evenly to ensure even cooking. Give your dish a little shake to help settle everything in.
5. Now, it’s time to add the final touch! Sprinkle the shredded cheese generously over the top of the casserole.
6. Bake in the preheated oven for 20-25 minutes. Keep an eye on it; you want the cheese to melt and become bubbly and slightly golden.
7. Once baked, let the casserole cool slightly before serving to avoid burning your mouth on that delicious melted cheese!
Serving Suggestions
This Chicken Fajita Casserole is delicious on its own, but you can elevate your meal even further with some great serving ideas. Consider pairing it with a fresh garden salad drizzled with a light vinaigrette. For a hearty touch, serve it alongside some warm tortilla chips and guacamole for dipping. A refreshing beverage, such as iced tea or a light beer, also makes a great accompaniment. Whether it’s a family dinner or a gathering with friends, this dish is sure to be the star of the table!
Storing and Reheating
If you happen to have leftovers (which may be unlikely, given how tasty this casserole is!), it’s easy to store and reheat for later. Let the dish cool completely, then transfer it to an airtight container. It will stay fresh in your refrigerator for about 3-4 days. For longer storage, you can freeze portions of the casserole for up to 3 months. Just make sure to thaw it in the refrigerator overnight before reheating.
To reheat, you can use the microwave or the oven. If using a microwave, heat in short intervals until warmed through. For oven reheating, cover the casserole with foil to prevent excessive browning and bake at 350°F until heated thoroughly.
Helpful Tips for Success
To ensure your Chicken Fajita Casserole turns out perfectly every time, keep these pro tips in mind:
- Don’t overcook the chicken at the sautéing stage; it should be cooked through but still tender. Overcooking can lead to dry chicken.
- Feel free to adjust the fajita seasoning according to your taste. If your family loves spice, try adding some diced jalapeños!
- Make sure your rice is fully cooked and slightly cooled before mixing it into the casserole to ensure even cooking throughout.
- As a quick tip, you can use leftover rotisserie chicken for even faster prep.
Delicious Variations to Try
If you want to mix things up, there are many possible variations to this casserole recipe:
- For a vegetarian option, omit the chicken and double up on the black beans or add some corn for extra crunch.
- Try using different proteins like ground turkey or shrimp to change the flavor profile.
- If you love cheese, experiment with different varieties such as pepper jack for a spicy twist.
- Switch out the bell peppers for other vegetables like zucchini or spinach for a unique texture.
