Essential Ingredients
Here’s what you’ll need to make this delicious dish:
Boneless, Skinless Chicken Breasts: I usually use about 3-4 chicken breasts, but adjust based on your crowd size.
Bell Peppers: A mix of red, yellow, and green peppers adds color and sweetness.
Onion: Sweet onions work best for that perfect balance of flavor.
Taco Seasoning: Store-bought or homemade; it’s essential for that bold fajita flavor.
Cheddar Cheese: Shredded cheese melts beautifully and adds creaminess.
Sour Cream: A dollop on top gives a creamy finish that balances the spices perfectly.
Olive Oil: For sautéing the veggies and adding richness to the dish.
Cilantro (optional): Chopped fresh cilantro brightens up the flavors as a garnish.

How to Make Fajita Chicken Casserole Bake
Preheat and Prepare Your Baking Dish: Preheat your oven to 375°F (190°C). Spray a 9×13-inch baking dish with nonstick cooking spray to prevent sticking.
Sauté Your Veggies: In a large skillet over medium heat, add olive oil. Once hot, toss in sliced bell peppers and onions. Sauté until softened and fragrant—about 5-7 minutes—until they become translucent.
Add the Chicken and Seasonings: Stir in diced chicken breasts along with taco seasoning. Cook until the chicken is no longer pink—around 8-10 minutes—and it’s coated with all those flavorful spices.
Layer It Up!: In your prepared baking dish, layer half of the chicken mixture followed by half of the cheese. Repeat these layers until everything is used up; top with remaining cheese for a gooey finish.
Bake Until Bubbling: Place the casserole in your preheated oven and bake for 25-30 minutes or until golden brown and bubbly. Keep an eye out for that melty cheese!
Serve with Style!: Once out of the oven, let it cool slightly before serving. Garnish with chopped cilantro if desired. Serve hot with sour cream on the side for an added touch of creaminess!
There you have it: an utterly scrumptious Fajita Chicken Casserole Bake that brings joy to both your taste buds and your dinner table!
