For the Chicken Marinade:

  • 1 pound boneless, skinless chicken breasts
  • 2 tablespoons olive oil
  • 1 teaspoon chili powder
  • 1 teaspoon cumin
  • 1/2 teaspoon smoked paprika
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • Salt and black pepper to taste
  • Juice of 1 lime

For the Casserole:

  • 2 bell peppers (red, green, or a combination), thinly sliced
  • 1 onion, thinly sliced
  • 2 cups cooked rice (white or brown)
  • 1 cup corn kernels (fresh, frozen, or canned)
  • 1 cup black beans, drained and rinsed
  • 1 1/2 cups shredded cheddar or Mexican cheese blend
  • 1/4 cup chopped fresh cilantro (optional, for garnish)
  • Lime wedges, sour cream, and salsa for serving


Step 1: Marinate the Chicken

  1. In a bowl, combine the olive oil, chili powder, cumin, smoked paprika, garlic powder, onion powder, salt, black pepper, and lime juice.
  2. Place the chicken breasts in a resealable plastic bag or a shallow dish. Pour the marinade over the chicken, seal the bag or cover the dish, and refrigerate for at least 30 minutes (or up to 8 hours for more flavor).

Step 2: Cook the Chicken

  1. Preheat your grill or grill pan over medium-high heat.
  2. Grill the marinated chicken for approximately 6-8 minutes per side, or until the internal temperature reaches 165°F (74°C) and the chicken is cooked through. Remove from the grill and let it rest for a few minutes.
  3. Once rested, slice the grilled chicken into thin strips.

Step 3: Prepare the Casserole

  1. Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish.
  2. In a large mixing bowl, combine the cooked rice, corn kernels, black beans, and half of the shredded cheese.
  3. Add the sliced bell peppers and onions to the bowl, followed by the grilled chicken strips. Mix everything together until well combined.

Step 4: Assemble and Bake

  1. Transfer the mixture to the greased baking dish and spread it out evenly.
  2. Sprinkle the remaining shredded cheese over the top of the casserole.
  3. Bake in the preheated oven for approximately 20-25 minutes or until the cheese is melted and bubbly, and the casserole is heated through.

Step 5: Garnish and Serve

  1. Remove the Chicken Fajita Casserole from the oven and garnish it with chopped fresh cilantro (if desired).
  2. Serve hot with lime wedges, sour cream, and salsa on the side.
