Description

A vibrant and flavorful Chicken Fajita Casserole packed with seasoned chicken, colorful bell peppers, zesty tomatoes, and melted cheese, all baked to perfection in one easy dish.


Ingredients

  • 1 1/2 lbs boneless, skinless chicken breasts, sliced into strips
  • 1 red bell pepper, sliced
  • 1 yellow bell pepper, sliced
  • 1 green bell pepper, sliced
  • 1 medium onion, sliced
  • 2 tablespoons olive oil
  • 2 tablespoons fajita seasoning
  • 1 teaspoon garlic powder
  • 1 teaspoon chili powder
  • 1 teaspoon ground cumin
  • 1/2 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 (10 oz) can diced tomatoes with green chilies, drained
  • 1 cup shredded cheddar cheese
  • 1 cup shredded Monterey Jack cheese
  • 1 tablespoon fresh lime juice
  • 2 tablespoons fresh cilantro, chopped (optional)

Instructions

  1. Preheat oven to 400°F (200°C) and lightly grease a 9×13-inch baking dish.
  2. In a large bowl, combine sliced chicken with olive oil, fajita seasoning, garlic powder, chili powder, cumin, salt, pepper, and lime juice. Toss to coat evenly.
  3. Add sliced bell peppers and onion to the bowl and mix until vegetables are coated.
  4. Spread half of the chicken and vegetable mixture evenly into the prepared baking dish.
  5. Sprinkle half of the drained diced tomatoes over the mixture, then top with half of the shredded cheeses.
  6. Repeat layers with remaining chicken mixture, tomatoes, and cheeses.
  7. Cover with foil and bake for 20 minutes.
  8. Remove foil and bake an additional 10–15 minutes, until chicken reaches 165°F (74°C) and cheese is melted and bubbly.
  9. Let rest for 5 minutes before serving. Garnish with chopped cilantro if desired.

Notes

  • Drain tomatoes thoroughly to prevent excess liquid.
  • For a spicier version, add jalapeños or extra chili powder.
  • Can be assembled up to 24 hours ahead and refrigerated before baking.
  • Store leftovers in the refrigerator for up to 4 days or freeze for up to 3 months.
  • Ensure fajita seasoning is gluten-free if needed.
