Step-by-Step Instructions

Follow these simple steps to create your creamy fajita chicken casserole:

1. Preheat your oven to 375°F (190°C).
2. In a large skillet, sauté the sliced bell peppers and onion over medium heat until they are tender, about 5-7 minutes.
3. In a mixing bowl, combine the softened cream cheese, tomato sauce, half the fajita seasoning, and chicken stock until well blended.
4. In a 9×13 inch baking dish, layer the sautéed vegetables, followed by the chicken breasts. Pour the creamy sauce over the top and sprinkle with the remaining fajita seasoning.
5. Cover with foil and bake for 25 minutes. Remove the foil, sprinkle with cheddar cheese, and bake for an additional 10-15 minutes until the chicken is cooked through and the cheese is bubbly.
6. Let the casserole cool for a few minutes before serving. Top with sour cream and sliced avocado.

Expert Tips for Perfecting Your Casserole

Want to ensure your casserole turns out perfectly every time? Here are some expert insights:
