Cooking Instructions
  1. In a large bowl, combine 1 tablespoon of fajita seasoning with 1 tablespoon of olive oil. Mix well to form a paste. Add chicken strips and toss until they are completely coated with the seasoning. Use your hands to make sure everything is well coated.
  2. Transfer the seasoned chicken into a greased 9x13-inch casserole dish and spread evenly.
  3. In the same bowl, combine the remaining tablespoon of fajita seasoning and olive oil. Add the sliced bell peppers and onions, and toss them to coat evenly.
  4. Place the seasoned peppers and onions over the chicken in the casserole dish. Sprinkle shredded cheese over the top.
  5. Bake in a preheated 350°F oven for 30-35 minutes, until the chicken is cooked through and the cheese is melted and bubbly.
  6. Remove from the oven and garnish with fresh cilantro. Serve hot with warmed tortillas and toppings like sour cream, diced avocado, tomatoes, and jalapeños.

Notes

  • For a spicier kick, add sliced jalapeños to the vegetable mix before baking.
  • You can substitute chicken thighs for a juicier option.
  • If you prefer a different cheese, Monterey Jack or Pepper Jack also work great in this casserole.
