How to Make Chicken Fajita Casserole
Step 1: Preheat the Oven
Preheat your oven to 350°F. Lightly spray a 9×13 inch baking dish with nonstick cooking spray to prevent sticking.
Step 2: Mix Ingredients
In a large bowl, stir together the following:
1. Shredded chicken
2. Uncooked rice
3. Cream of chicken soup
4. Sour cream
5. Frozen diced onion and bell pepper blend
6. Diced tomatoes with chilies
7. Chicken broth
8. Fajita seasoning
9. About half of the shredded cheese
Make sure everything is combined well.
Step 3: Bake the Casserole
Pour the mixture into your prepared baking dish and spread it evenly across the bottom. Cover tightly with aluminum foil to keep moisture in during cooking.
Bake for about 35 to 45 minutes, or until the rice is tender and has absorbed most of the liquid.

Remove from the oven and carefully take off the foil. Top with the remaining shredded cheese and return to the oven until melted, about an additional 5–10 minutes.

Common Mistakes to Avoid
Cooking can be fun, but it’s easy to make mistakes. Here are some common pitfalls to steer clear of when making your Chicken Fajita Casserole.
- Skipping the Preheat: Not preheating your oven can result in uneven cooking. Always preheat your oven to 350°F to ensure even baking.
- Ignoring the Cooking Time: Leaving your casserole in the oven too long or not long enough can affect texture. Keep an eye on the clock and check for tender rice.
- Using Cold Ingredients: Cold ingredients can cause longer cooking times. Make sure your chicken is at room temperature before mixing.
- Overloading with Toppings: Adding too many toppings at once can lead to a soggy casserole. Stick to the recipe’s suggested cheese amount for the best results.
- Not Covering During Baking: Skipping foil coverage can dry out your casserole. Make sure to wrap it tightly before baking for a moist outcome.
- Neglecting Flavor Adjustments: Fajita seasoning varies by brand; always taste and adjust as needed. Don’t hesitate to add more seasoning if you prefer stronger flavors.
