Ingredients

  • 1 1/2 lb chicken breast, sliced
  • 3 bell peppers, sliced
  • 1 large onion, sliced
  • 2 tablespoons olive oil
  • 2 tablespoons fajita seasoning
  • 1/2 teaspoon salt
  • 1/2 teaspoon black pepper
  • 3 cups cooked rice
  • 1 can (15 oz) black beans, drained and rinsed
  • 1 cup corn kernels
  • 1 1/2 cups shredded cheddar or Mexican-blend cheese
  • Fresh cilantro, chopped (for garnish)

Instructions

  1. Preheat the oven to 375°F (190°C) and lightly grease a casserole dish.
  2. In a large bowl, toss the sliced chicken with olive oil, fajita seasoning, salt, and black pepper.
  3. Add the bell peppers and onion to the bowl and mix until everything is evenly coated.
  4. Spread the cooked rice evenly in the bottom of the prepared casserole dish.
  5. Layer the chicken and vegetable mixture over the rice.
  6. Sprinkle the black beans and corn evenly over the top.
  7. Cover with foil and bake for 30 minutes, or until the chicken is cooked through and vegetables are tender.
  8. Remove the foil, sprinkle the cheese over the casserole, and return to the oven for 5–10 minutes until melted and bubbly.
  9. Garnish with fresh cilantro before serving.

Notes

  • Chicken thighs can be used instead of breasts for extra juiciness.
  • Cauliflower rice works well for a lower-carb version.
  • Add jalapeños or chili powder for more heat.
  • A splash of water helps keep leftovers moist when reheating.
