Instructions

Preheat and Season: Preheat oven to 400°F (200°C). In a baking dish, season chicken breasts with fajita seasoning and vegetable oil. Make sure the seasoning is evenly distributed.
Top and Bake: Arrange bell pepper strips and onion slices over the chicken. Sprinkle with a little more fajita seasoning and top with shredded cheese. Bake uncovered for 25-30 minutes, or until chicken reaches an internal temperature of 165°F (74°C).
Serve: Serve immediately, garnished with fresh cilantro, if desired.

Notes

To ensure chicken is cooked through, check the internal temperature with a meat thermometer.
For a lower-calorie version, omit the cheese or replace it with a sprinkle of Parmesan cheese mixed with panko breadcrumbs.
To cook the casserole faster, cut the chicken into smaller pieces and reduce the cooking time.
You can add cooked pasta to the casserole for a heartier meal.
Serve with rice, pasta, or cauliflower rice.
Reheat leftovers in the oven or microwave.
