Recipe Ingredients for Chicken Fajita Casserole

When creating the Chicken Fajita Casserole, the ingredients come together harmoniously to create a satisfying meal. Each element plays a vital role in building flavor and texture, from the succulent chicken to the creamy sauce. Here’s what you will need:
- 4 cups shredded cooked chicken (about two large breasts) – This is the star of the dish. Using cooked chicken makes it quick to prepare.
- 2 cups instant rice – Provides a hearty base that absorbs all the wonderful flavors.
- 10.5 ounces cream of chicken soup – Adds creaminess and richness to the casserole.
- 1 cup sour cream – Intensifies the creaminess while balancing the spices.
- 1 red bell pepper (seeded and diced) – Brings a pop of color and sweetness.
- 1 large onion (diced) – Adds depth and savory flavor.
- 1 ½ cups chicken broth – Keeps the casserole moist while enhancing the chicken flavor.

Cooking Instructions for Chicken Fajita Casserole

Making the Chicken Fajita Casserole is a breeze! It’s all about layering the ingredients and letting your oven do the magic. Here are the steps to create this flavorful dish:
Preheat your oven to 350 degrees Fahrenheit. This is crucial for ensuring your casserole bakes evenly and thoroughly. While the oven is heating, you can prepare your baking dish.
Lightly spray a 9×13 inch baking dish with nonstick cooking spray. This will help prevent sticking and make serving easier.
In a large bowl, stir together the chicken, uncooked rice, cream of chicken, sour cream, diced onion, chicken broth, diced bell pepper, fajita seasoning, and half of the cheese. Make sure everything is well combined for even flavor distribution.
Pour the mixture into the prepared dish and spread it out evenly. This step ensures that every part of the casserole cooks uniformly.
Wrap the dish tightly in aluminum foil. This helps keep moisture in while baking, allowing the flavors to meld beautifully.
Bake in the preheated oven at 350 degrees Fahrenheit for 35 to 40 minutes or until it is bubbling. You’ll know it’s done when you see the edges bubbling and the top is slightly golden.
Remove from the oven, top with the remaining cheese, and return to the oven, uncovered, until the cheese is melted, about 5 minutes. This step adds that irresistible cheesy layer!
Let rest for 5 minutes before serving. This waiting time allows the casserole to set, making it easier to cut and serve.
Things Worth Knowing
- Don’t rush the resting time: Allowing the casserole to rest helps it set, making it easier to serve and enhancing the flavors.
- Use cooked chicken: For convenience, using pre-cooked chicken saves you time and ensures tenderness.
- Layering is key: Ensure even distribution of ingredients by mixing thoroughly and spreading uniformly in the baking dish.
