Ingredients
Main Ingredients
– Chicken and Vegetables
– 1 lb boneless, skinless chicken breasts, cut into strips
– 1 bell pepper (red or yellow), sliced into thin strips
– 1 medium onion, sliced into thin rings
– 2 garlic cloves, minced into a paste
Chicken is the star here. It cooks fast and adds great flavor. I prefer using boneless, skinless chicken breasts for this dish. They stay tender and juicy. The bell pepper and onion bring color and crunch. Adding garlic gives it a nice kick.
– Spices and Seasoning
– 1 teaspoon ground cumin
– 1 teaspoon smoked paprika
– ½ teaspoon chili powder
– Salt and freshly ground black pepper, to taste
These spices create that classic fajita flavor. Cumin adds warmth, while smoked paprika gives a nice depth. Adjust the chili powder for your heat level. A little salt and pepper enhances all the flavors.
– Base Ingredients
– 1 can (15 oz) black beans, thoroughly drained and rinsed
– 1 cup corn kernels (can use fresh or frozen)
– 1 cup salsa (choose mild or spicy based on your preference)
– 2 cups cooked rice (white, brown, or cauliflower rice works well)
The black beans and corn add fiber and sweetness. Salsa ties it all together with moisture and zest. Use your favorite type of rice for the base. It soaks up all those tasty juices.
– Cheese and Garnishes
– 1 ½ cups shredded cheese (use cheddar or a Mexican blend for flavor)
– Fresh cilantro, chopped, for garnish (optional)
Cheese is essential for that gooey top layer. I love a mix of cheddar and Mexican blends for extra flavor. Cilantro adds freshness. You can skip it if you’re not a fan, but it brightens the dish.

Tips & Tricks
Best Practices
– Choosing the right chicken cuts
Use boneless, skinless chicken breasts for a lean option. They cook evenly and stay juicy. You can also use chicken thighs for more flavor.
– Tips for perfecting the sauté
Heat your pan on medium heat before adding oil. This helps the chicken get a nice sear. Cook the chicken until it’s no longer pink, about 5-7 minutes. Stir it often for even cooking.
– Cheese selection for better melting
I recommend using cheddar or a Mexican cheese blend. These melt well and add great flavor. Grate your own cheese for the best results.
Common Mistakes to Avoid
– Overcooking the chicken
Avoid cooking the chicken too long. It can dry out quickly. Check for doneness by cutting into a piece to see if it’s no longer pink.
– Skipping the resting time
Let the casserole rest for about 5 minutes after baking. This helps the flavors blend and makes serving easier.
– Ignoring seasoning balance
Don’t skip the spices! They add depth to your dish. Taste your mixture and adjust the salt and pepper as needed.
Pro Tips
- Use Fresh Ingredients: Fresh bell peppers and onions enhance the flavor profile of your casserole, making it more vibrant and delicious.
- Customize Your Spice Level: Adjust the amount of chili powder in the recipe to suit your taste, or add diced jalapeños for an extra kick!
- Cheese Variations: Experiment with different cheese blends such as pepper jack or queso fresco for a unique twist on the traditional flavor.
- Make Ahead: Prepare the casserole in advance and store it in the fridge. Just bake it when you’re ready for a quick meal!

Variations
Ingredient Swaps
Protein alternatives
You can use different proteins in this dish. Ground turkey or beef works well. You might even try shrimp for a seafood twist. Tofu is great for a meatless option.
Vegetable variations
Feel free to change the veggies! Zucchini, mushrooms, or even spinach can add fresh flavors. You can also mix in some jalapeños for heat. The more colorful, the better!
Different types of rice
Rice is the base of this casserole. You can use white rice for a classic taste. Brown rice adds more fiber, while cauliflower rice is low-carb. Each type brings a unique texture to the dish.
Flavor Enhancements
Spicy vs. mild salsas
Choose your salsa wisely. If you love spice, go for a hot salsa. If you prefer mild, select a smooth salsa. You can also mix both for a balanced flavor.
Adding beans or legumes
Beans add protein and fiber. Black beans are a must, but pinto or kidney beans are great too. You can even use lentils for a different taste.
Incorporating fresh herbs
Fresh herbs add brightness. Cilantro is a favorite, but parsley or green onions also work. Just sprinkle them on top before serving for extra flavor.
Storage Info
Refrigeration Guidelines
To store leftovers, let the casserole cool first. Place it in an airtight container. You can keep it in the fridge for up to three days. When you want to eat it again, just take it out and reheat. For reheating, use the oven or microwave. If using an oven, heat to 350°F (175°C) until warm. In the microwave, warm in short bursts. Stir often to heat evenly.
Freezing Instructions
To freeze the casserole, let it cool completely. Then, wrap it tightly in plastic wrap. After that, place it in a freezer-safe container. This helps keep it fresh. You can store it in the freezer for up to three months.
When you want to eat it, take it out and let it thaw. The best way to thaw is in the fridge overnight. After thawing, reheat it in the oven or microwave. Make sure it is heated all the way through. You will know it’s ready when it is hot in the center. Enjoy your meal!

- 1 medium onion, sliced into thin rings
- 2 cloves garlic, minced into a paste
- 1 teaspoon ground cumin
- 1 teaspoon smoked paprika
- 0.5 teaspoon chili powder
- to taste salt and freshly ground black pepper
- 1 can (15 oz) black beans, thoroughly drained and rinsed
- 1 cup corn kernels (fresh or frozen)
- 1 cup salsa (mild or spicy)
- 2 cups cooked rice (white, brown, or cauliflower rice)
- 1.5 cups shredded cheese (cheddar or Mexican blend)
- optional fresh cilantro, chopped, for garnish
Preheat your oven to 350°F (175°C). This ensures a hot oven for even baking.
In a large skillet, pour in the olive oil and heat over medium heat. Add the chicken strips and sauté them until they are cooked through and no longer pink in the center, approximately 5-7 minutes.
Once the chicken is cooked, add the sliced bell pepper, onion, and minced garlic. Sauté together until the vegetables become tender, about 3-5 minutes. Stir occasionally to ensure even cooking.
Season the mixture with ground cumin, smoked paprika, chili powder, salt, and freshly ground black pepper. Stir thoroughly to ensure that the spices are evenly distributed throughout the chicken and vegetables.
In a large mixing bowl, combine the black beans, corn, salsa, and cooked rice. Gently fold in the chicken and vegetable mixture, ensuring that all ingredients are well mixed and coated in the salsa.
Transfer the entire mixture to a greased casserole dish, spreading it evenly with a spatula or the back of a spoon.
Sprinkle the shredded cheese generously over the top, ensuring that it covers the entire surface of the casserole for that delicious cheesy topping.
Bake in the preheated oven for 25-30 minutes, or until the cheese is bubbly and lightly golden on top, indicating it’s perfectly melted.
Once done, remove the casserole from the oven and allow it to cool for about 5 minutes. This helps the flavors meld and makes serving easier.
Serve warm, garnished with chopped fresh cilantro if desired, for a burst of color and flavor.
Feel free to adjust the spice level by choosing mild or spicy salsa.
