🥘 Ingredients
📋 Instructions
- 1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish and set aside.
- 2. In a large skillet over medium-high heat, heat olive oil. Add chicken strips and season with fajita seasoning, garlic powder, smoked paprika, cumin, salt, and pepper. Sauté for 4–5 minutes until lightly browned but not fully cooked through. Remove from skillet and set aside.
- 3. In the same skillet, add sliced bell peppers and onion. Sauté for 3–4 minutes until slightly softened and beginning to char at the edges. Remove from heat.
- 4. In a large mixing bowl, combine uncooked rice, chicken broth, diced tomatoes with green chilies, and sour cream. Stir well until fully combined.
- 5. Pour the rice mixture evenly into the prepared baking dish. Layer the sautéed chicken strips over the rice mixture, then top with the sautéed peppers and onions.
- 6. Cover tightly with aluminum foil and bake for 30 minutes, until the rice is fully cooked and has absorbed the liquid.
- 7. Remove foil, sprinkle the shredded Mexican blend cheese evenly over the top, and return to the oven uncovered for 5–7 minutes, until the cheese is fully melted, golden, and bubbly.
- 8. Remove from oven and let rest for 5 minutes. Garnish with fresh chopped cilantro and serve with lime wedges on the side.
💡 Tips & Notes
- • For a spicier kick, add 1–2 diced jalapeños with the bell peppers, or use hot Rotel instead of mild.
- • You can substitute the white rice with brown rice — just increase the chicken broth to 2.5 cups and extend covered bake time to 50 minutes.
- • Leftover casserole stores beautifully in an airtight container in the fridge for up to 4 days. Reheat with a splash of chicken broth to keep the rice moist.
- • To make this a complete Mexican chicken and rice with queso experience, drizzle store-bought or homemade queso sauce over individual servings before plating.
- • This recipe also works great in a slow cooker — cook on LOW for 4–5 hours, adding the cheese in the final 20 minutes with the lid off.

Step-by-Step Cooking Instructions
Preparation is straightforward and doesn’t require fancy knife skills. Start by preheating your oven to 350 degrees Fahrenheit. This temperature cooks everything evenly without drying out the chicken.
Heat olive oil in a large skillet over medium-high heat. Season your chicken pieces generously with salt and pepper first. Cook the chicken until golden on all sides, about five minutes total. The chicken doesn’t need to be fully cooked here. It will finish cooking in the casserole dish.
Remove the chicken and set it aside on a clean plate. In the same skillet, add your onions and bell peppers. Sauté them for about three minutes until they’re slightly softened. This step builds incredible flavor from caramelization.
Add the fajita seasoning to the vegetables and stir well. Cook for another minute until fragrant and beautiful. Return the chicken to the skillet and toss everything together.
Now for the casserole assembly. Spray a nine-by-thirteen-inch baking dish with cooking spray. Pour the uncooked rice evenly across the bottom of the dish. Spread the chicken and vegetable mixture over the rice layer.
In a bowl, combine your chicken broth with the diced tomatoes and green chilies. Pour this mixture evenly over everything in the dish. Sprinkle one cup of cheese over the top evenly.
Cover the casserole dish tightly with aluminum foil. Bake for forty-five minutes without lifting the lid. The steam trapped inside cooks everything perfectly. Check that the rice is tender and all liquid is absorbed.
Remove the foil and stir in your black beans and corn. Sprinkle the remaining cheese over the top evenly. Bake uncovered for another ten minutes until cheese melts beautifully.
Let the casserole rest for five minutes before serving. This allows the rice to set and makes serving much easier. The residual heat will be just right for eating.
Pro Tips for Perfect Results
Consistency matters more than you might think here. Using long-grain white rice gives you the fluffiest texture. Brown rice works but requires additional liquid and cooking time.
Don’t skip browning the chicken first. This creates a flavorful crust that adds depth. It also ensures your chicken stays tender throughout cooking.
Make sure your baking dish is completely covered during cooking. Foil should not leave any gaps for steam to escape. This prevents the rice from drying out prematurely.
If you prefer spicier fajitas, add jalapeños to the vegetable layer. Fresh peppers add heat and incredible flavor complexity. Remove seeds if you want less spice overall.
The casserole reheats beautifully, making it perfect for meal prep. Store leftovers in an airtight container for up to four days. Add a splash of broth when reheating to restore moisture.
Prepare your ingredients in advance to speed up cooking. Having everything chopped and measured saves precious weeknight minutes. This is especially helpful when cooking with kids.
Delicious Topping Ideas to Elevate Your Dish

Variations to Keep Things Interesting
This casserole recipe adapts beautifully to different preferences. Swap chicken for ground beef if that’s your preference. Brown the beef first and season it identically for consistency.
Vegetarians can skip the meat entirely and add extra beans. Use vegetable broth instead of chicken broth. The result is equally delicious and satisfying.
Try brown rice for a nuttier flavor and heartier texture. Just use one additional cup of broth. Increase baking time to fifty-five minutes total.
Add black olives or jalapeños directly to the casserole. Corn and zucchini work wonderfully as additional vegetables. Get creative with peppers based on what you enjoy most.
For a lower-carb version, substitute cauliflower rice for regular rice. This keeps all the flavor while reducing carbohydrates significantly. Adjust liquid accordingly based on moisture content.
Serving Suggestions for Complete Meals
This casserole stands alone as a complete meal. The combination of protein, vegetables, and rice covers all bases. However, sides enhance the experience wonderfully.
A simple green salad provides refreshing contrast to the rich casserole. Dress it with lime vinaigrette for cohesive flavors. The acidity cuts through the cheese beautifully.
Warm flour tortillas on the side let guests make wraps. This adds fun texture variation and interactive dining. Warm them directly over a gas flame for charred spots.
Guacamole and salsa are natural accompaniments to serve alongside. Fresh mango salsa adds tropical notes and brightness. Both pair perfectly with fajita flavors.
Cornbread makes an unexpected but delicious pairing. Its slight sweetness balances the savory casserole perfectly. Serve with honey butter for extra indulgence.
Storage and Reheating Instructions
This casserole stores exceptionally well in the refrigerator. Place leftovers in airtight containers within two hours. Proper storage keeps everything fresh for up to four days.
Reheat individual portions in the microwave for convenience. Add a tablespoon of water or broth to prevent drying. Heat at fifty-percent power for even warming throughout.
For larger quantities, reheat in a 325-degree oven covered. Add extra broth if the rice seems dry. This method prevents overheating and maintains texture better.
Frozen portions work well up to three months. Thaw overnight in the refrigerator before reheating. This prevents uneven cooking and ensures food safety.
