Step‑by‑Step Instructions for Chicken Fajita Casserole Recipe Step 1: Preheat the Oven Begin by preheating your oven to 350°F (175°C). This step is crucial to ensure that your Chicken Fajita Casserole cooks evenly. As the oven heats, you can gather and prepare the other ingredients, so everything is ready to go once the oven reaches the desired temperature. Step 2: Prepare the Baking Dish Spray a 9×13 inch baking dish with nonstick cooking spray, ensuring it’s evenly coated. This will prevent the casserole from sticking and make for easy serving. Set the prepared baking dish aside while you mix the other ingredients for your savory Chicken Fajita Casserole. Step 3: Mix the Ingredients In a large mixing bowl, combine the shredded cooked chicken, uncooked instant rice, cream of chicken soup, sour cream, frozen diced onion and bell pepper blend, diced tomatoes with chilies, chicken broth, fajita seasoning, and half of the shredded cheese. Stir the mixture until everything is evenly combined and coated with the creamy goodness. Step 4: Transfer to Baking Dish Carefully pour the chicken mixture into the prepared baking dish, making sure to spread it evenly to ensure even cooking. Cover the dish tightly with aluminum foil, which will help trap moisture and cook the rice thoroughly in your Chicken Fajita Casserole. Step 5: Bake the Casserole Place the covered baking dish in the preheated oven and bake for 35 to 45 minutes. You’ll know it’s ready when the rice is tender and the mixture is bubbling gently. Keep an eye on it to avoid overcooking, ensuring a delightful texture for your casserole. Step 6: Add the Cheese Topping Once the casserole has finished baking, carefully remove it from the oven and take off the foil. Sprinkle the remaining cheese on top, creating a luscious layer that will melt beautifully. Return the casserole to the oven uncovered and bake for an additional 5 to 10 minutes, or until the cheese is golden and bubbly. Step 7: Let it Rest Before Serving After baking, take the Chicken Fajita Casserole out of the oven and allow it to sit for about 5 minutes. This rest time helps the layers settle and makes it easier to serve. Enjoy the vibrant flavors and creamy texture that make this dish a family favorite! Expert Tips for Chicken Fajita Casserole Use Rotisserie Chicken: For quick preparation, swapping shredded chicken with rotisserie chicken saves you time and enhances flavor.

Prep Ahead: Assemble the dish a day in advance and refrigerate; just remember to adjust the baking time for a perfect Chicken Fajita Casserole.
