Description

Chicken Fajita Casserole brings sizzling Southwest flavors right to your dinner table with zero fuss. Packed with tender chicken, colorful peppers, and melty cheese, this one-pan wonder makes weeknight meals deliciously simple.


Ingredients

Scale

Proteins:

  • 1.5 pounds skinless, boneless chicken breasts
  • 1.5 cups shredded cheese

Vegetables:

  • 2 medium bell peppers
  • 1 medium yellow onion

Seasonings and Oils:

  • 2 tablespoons fajita seasoning
  • 1 tablespoon vegetable oil
  • Fresh chopped cilantro

Instructions

  1. Preheat your oven to 400°F and grab a large baking dish to prepare your fajita feast.
  2. Drizzle 1 tablespoon vegetable oil over 1 ½ pounds chicken breasts, then generously coat with 2 tablespoons fajita seasoning, ensuring every inch is covered.
  3. Slice 2 bell peppers and 1 yellow onion into thin strips, creating colorful vegetable ribbons for your casserole.
  4. Layer the seasoned chicken at the bottom of the baking dish, then arrange the pepper and onion strips evenly across the top.
  5. Sprinkle an additional dash of fajita seasoning over the vegetables for extra flavor intensity.
  6. Generously scatter 1 ½ cups shredded cheese across the entire surface, allowing it to melt and create a golden, bubbly topping.
  7. Slide the uncovered dish into the 400°F oven and bake for exactly 25-30 minutes until the chicken reaches 165°F internal temperature.
  8. Remove the casserole and let it rest for 3-5 minutes to allow juices to redistribute.
  9. Chop fresh cilantro and shower it over the top for a bright, fresh finish.
  10. Serve immediately with warm tortillas or fluffy rice to complete your meal.

Notes

  • Swap chicken breasts for thighs if dark meat provides more flavor and moisture for your preference.
  • Cut vegetables into uniform pieces to ensure even cooking and balanced texture in each bite.
  • Opt for low-fat cheese or dairy-free alternatives to make this dish more diet-friendly for specific nutritional needs.
  • Let the casserole rest for 5 minutes after baking to help juices redistribute and make serving easier.
