• Discover the essential ingredients for a delicious Chicken Fajita Casserole that your family will love!
For the Casserole
- Shredded Cooked Chicken – This is your main protein, and using rotisserie chicken saves time.
- Instant Rice – A quick base that absorbs all the wonderful flavors; if you want to reduce carbs, substitute with cauliflower rice.
- Cream of Chicken Soup – Provides that creamy richness; feel free to switch it up with cream of mushroom for a different taste.
- Sour Cream – Adding tang and creaminess, this can be replaced with Greek yogurt for a lighter dish.
- Frozen Diced Onion and Bell Pepper Blend – Convenient to use and adds great flavor; fresh veggies can be sautéed if you prefer.
- Diced Tomatoes with Chilies (Rotel) – They add moisture and a hint of spice; go for the mild version if you prefer less heat.
- Chicken Broth – Moisture is key for cooking the rice; low-sodium options work well here.
- Fajita Seasoning – Essential for that Tex-Mex flavor; don’t hesitate to use a homemade blend for maximum flavor.
- Shredded Mexican Blend Cheese – Melts beautifully on top, but feel free to substitute with cheddar or pepper jack for a different kick.
Step‑by‑Step Instructions for Chicken Fajita Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it warms up, grab a 9×13 inch baking dish and lightly spray it with nonstick cooking spray. This will prevent your Chicken Fajita Casserole from sticking and ensure an easy release after baking.
Step 2: Combine Ingredients
In a large mixing bowl, combine shredded cooked chicken, instant rice, cream of chicken soup, sour cream, and the frozen diced onion and bell pepper blend. Add the diced tomatoes with chilies, chicken broth, fajita seasoning, and half of the shredded cheese. Mix thoroughly until every ingredient is well incorporated, creating a rich, flavorful mixture.
Step 3: Transfer to Baking Dish
Pour the mixture into your prepared baking dish, spreading it out evenly with a spatula. Cover the dish tightly with aluminum foil to trap steam, which will help the rice cook evenly. This protective layer locks in the moisture while ensuring your Chicken Fajita Casserole develops a tender texture.
Step 4: Bake the Casserole
Place the covered baking dish into the preheated oven and bake for 35 to 45 minutes. Watch for the rice to become tender and absorb the flavors throughout. You’ll know it’s done when the edges are gently bubbling, and the casserole has a warm, inviting aroma filling your kitchen.
Step 5: Add Cheese and Finish Baking
After the initial baking time, carefully remove the foil from the casserole. Sprinkle the remaining cheese over the top, creating a deliciously gooey layer. Return the dish to the oven and bake uncovered for an additional 5 to 10 minutes, or until the cheese is melted and bubbly, turning a lovely golden brown.
Step 6: Let It Rest Before Serving
Once your Chicken Fajita Casserole is finished baking, take it out of the oven and allow it to rest for about 5-10 minutes. This resting period helps the layers to set slightly and makes serving easier. Enjoy the delightful blend of flavors and textures with your family!

Chicken Fajita Casserole Recipe FAQs
What kind of chicken should I use for my casserole?
Absolutely! The best option for this Chicken Fajita Casserole is shredded cooked chicken, and using rotisserie chicken makes it super convenient. If you have leftover grilled or baked chicken, you can shred that too. Just ensure it’s cooked through before mixing it into your casserole.
How do I store leftover Chicken Fajita Casserole?
After enjoying your delicious casserole, you can store leftovers in an airtight container in the fridge for up to 3 days. Simply reheat it in the oven or microwave until warmed through. I like to cover it loosely with foil while reheating to keep the cheese nice and melty!
Can I freeze Chicken Fajita Casserole?
Definitely! You can freeze the assembled Chicken Fajita Casserole before baking. Wrap it tightly with foil or plastic wrap to prevent freezer burn, and it will last for up to 2 months. To bake, simply thaw it overnight in the fridge and then follow the baking instructions.
What if my casserole turns out too dry?
Very importantly, if you find your casserole is dry after baking, it may be due to the rice absorbing too much moisture. To fix this, you can add an extra splash of chicken broth before baking, ensuring all ingredients are evenly mixed. Remember, if using regular rice, it might need adjustments in cooking time and liquid measurements.
Can I make this casserole ahead of time?
Yes! You can assemble the Chicken Fajita Casserole and store it in the refrigerator, tightly covered, for up to 24 hours before baking. Just keep in mind that the rice may absorb more moisture, so consider slightly reducing the chicken broth when making it ahead.
Is this casserole suitable for a low-carb diet?
The more the merrier! If you’re looking for a low-carb option, I recommend substituting cauliflower rice for the instant rice. Just be sure to adjust the liquid since cauliflower rice cooks more quickly. You’ll still enjoy all the flavors while keeping it lighter!
