Description

This Chicken Fajita Casserole is a quick and flavorful one-dish meal combining tender, seasoned chicken breasts with colorful bell peppers, onions, and melty cheese, baked to perfection. Ideal for a weeknight dinner, it brings the vibrant fajita flavors into a comforting casserole form.


Ingredients

Chicken and Seasoning

  • 1 ½ pounds chicken breasts (skinless and boneless)
  • 2 tablespoons fajita seasoning
  • 1 tablespoon vegetable oil

Vegetables

  • 2 medium bell peppers (cut into strips)
  • 1 medium yellow onion (sliced)

Toppings

  • 1 ½ cups shredded cheese (cheddar or a Mexican blend works well)
  • Fresh chopped cilantro (for garnish)


Instructions

  1. Preheat Oven: Preheat your oven to 400°F (200°C) to prepare for baking the casserole.
  2. Season Chicken: In your baking dish, evenly season the chicken breasts with the fajita seasoning and vegetable oil. Use your hands to make sure the seasoning coats the chicken thoroughly for full flavor.
  3. Add Vegetables and Cheese: Layer the sliced bell peppers and onions over the seasoned chicken. Sprinkle a bit more fajita seasoning on top for extra flavor, then cover everything with shredded cheese.
  4. Bake: Place the casserole uncovered in the preheated oven and bake for 25-30 minutes, until the chicken is cooked through and the cheese is melted and bubbly.
  5. Serve: Remove from the oven and garnish with fresh chopped cilantro. Serve immediately for a delicious, hearty meal.

Notes

  • You can substitute fajita seasoning with a homemade blend of chili powder, cumin, paprika, garlic powder, onion powder, salt, and pepper.
  • Use any cheese you prefer, such as Monterey Jack, mozzarella, or a blend of cheeses for different flavor profiles.
  • Make sure chicken is fully cooked to an internal temperature of 165°F (74°C) for food safety.
  • Serve with warm tortillas, rice, or beans for a complete meal.
