Ingredients

Scale

Chicken and Seasoning

  • 1 lb (450g) boneless skinless chicken breasts, cut into strips
  • 2 tablespoons olive oil
  • 1 packet fajita seasoning mix
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper

Vegetables

  • 1 red bell pepper, sliced
  • 1 green bell pepper, sliced
  • 1 yellow onion, sliced
  • 1 (10 oz) can diced tomatoes with green chilies, drained

Dairy

  • 2 cups (200g) shredded cheddar cheese, divided
  • 1 cup (240ml) sour cream

Garnish and Serving

  • Fresh cilantro, for garnish
  • Lime wedges, for serving


Instructions

  1. Preheat oven: Preheat your oven to 375°F (190°C) to get it ready for baking the casserole.
  2. Cook chicken: In a large skillet over medium-high heat, add olive oil. Once hot, add the chicken strips and cook them until browned and fully cooked through, about 5-7 minutes. Remove from heat.
  3. Season chicken: Add the fajita seasoning mix to the cooked chicken strips and stir well until all pieces are coated evenly with the seasoning.
  4. Mix ingredients: In a large bowl, combine the seasoned chicken, sliced bell peppers and onion, 1 cup of shredded cheddar cheese, sour cream, drained diced tomatoes with green chilies, garlic powder, and onion powder. Mix thoroughly until all ingredients are evenly blended.
  5. Assemble casserole: Pour the chicken and vegetable mixture into a greased 9×13 inch (23×33 cm) baking dish. Spread evenly for a uniform casserole base.
  6. Add cheese topping: Sprinkle the remaining 1 cup of shredded cheddar cheese evenly over the top of the casserole mixture to create a cheesy crust.
  7. First bake: Cover the dish with aluminum foil and bake in the preheated oven for 20 minutes to heat through and meld flavors.
  8. Remove foil and continue baking: Take off the foil and bake for an additional 10 minutes. This will let the cheese on top become bubbly and golden brown.
  9. Cool: Remove the casserole from the oven and allow it to cool for a few minutes for easier serving.
  10. Garnish and serve: Garnish the casserole with fresh cilantro and serve with lime wedges on the side to add a fresh, zesty finish.

Notes

  • For a spicier casserole, add extra diced jalapeños or hot sauce to the mixture before baking.
  • Use sharp cheddar cheese for more pronounced flavor or a Mexican blend cheese for a more authentic taste.
  • Leftovers can be stored in an airtight container in the refrigerator for up to 3 days and reheated in the oven or microwave.
  • Feel free to substitute chicken breasts with thighs for a juicier texture.
  • This casserole pairs well with a side of cilantro lime rice or warm tortillas for a complete meal.
