How to Make Fajita Chicken Casserole

Follow these simple steps to create your own delicious Fajita Chicken Casserole. This recipe is designed to be straightforward, making it perfect for any cook, and it truly lives up to its one-pan fajita chicken casserole name!

Step 1: Preheat your oven to 350°F (175°C). Take a 9×13 inch baking dish and give it a light coating of cooking spray. This prevents any sticking and makes for easy cleanup.
Step 2: In a large bowl, gather all your main ingredients. Combine the 4 cups shredded cooked chicken, 2 cups uncooked instant rice, 1 can (295g) cream of chicken soup, 240ml sour cream, 1 cup frozen diced onion and bell pepper blend, 1 can (285g) diced tomatoes with chilies, undrained, 375ml chicken broth, and the 1 packet (34g) fajita seasoning. Add about half of your 225g shredded Mexican blend cheese to the bowl as well.
Step 3: Now, it’s time to mix it all up! Use a sturdy spoon or your hands to gently combine everything until it’s well incorporated. You want to make sure the rice and chicken are evenly coated in that creamy, spicy mixture.
Step 4: Pour this flavorful mixture into your prepared baking dish. Spread it out evenly so that it bakes uniformly. The aroma at this stage is already amazing!
Step 5: Place the dish in your preheated oven. Let it bake for about 25 minutes. You’ll know it’s ready to come out when the rice has absorbed most of the liquid and the mixture is hot and bubbly around the edges.
Step 6: Carefully remove the casserole from the oven. Sprinkle the remaining shredded cheese evenly over the top. This is what gives you that gorgeous, melty finish.
Step 7: Return the dish to the oven for another 5-10 minutes. Bake until the cheese is completely melted, golden, and wonderfully bubbly. This final step really ties the whole dish together.
Step 8: Once out of the oven, let your incredible how to make fajita chicken casserole creation rest for about 5 minutes. This allows the flavors to meld and makes it easier to serve. Enjoy this simple yet satisfying meal!

Want to elevate your casserole game? These simple tricks will ensure your Fajita Chicken Casserole is a showstopper every single time!

Don’t Skimp on the Fajita Seasoning: This is where the flavor magic happens! Make sure you use the full packet, or even a little extra if you love bold Tex-Mex taste.
Use Rotisserie Chicken: For ultimate ease and flavor, a pre-cooked rotisserie chicken is your best friend. It’s already seasoned and perfectly tender.

The most common pitfall is an undercooked or mushy casserole. To avoid this, ensure your oven temperature is accurate and don’t over-bake it. For a truly hearty chicken fajita casserole, resist the urge to add too much extra liquid, as the instant rice will absorb what’s there.
