- 1 1/2 cups chicken broth: Keeps everything moist and infuses extra savory depth.
- 1 (1.12-ounce) packet fajita seasoning: The heart of fajita flavor, providing just the right zing and spice.

How to Make Fajita Chicken Casserole Recipe
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C). While it warms, grab a casserole dish and give it a quick grease with butter or non-stick spray—this little prep prevents sticking and helps with easy serving later on.
Step 2: Mix the Magic
In a large bowl, combine all the main ingredients: shredded chicken, instant rice, cream of chicken soup, sour cream, the frozen onion and bell pepper blend, diced tomatoes with chilies (undrained), chicken broth, fajita seasoning, and half of the shredded cheese. Stir everything together until all ingredients are evenly incorporated and coated in that rich, flavorful sauce. The beautiful colors and smells should start to make your mouth water right about now.
Step 3: Bake with Love
Pour your mixture into the prepared baking dish, smoothing it out evenly. Pop it into the preheated oven and bake for 25 to 30 minutes, allowing all the flavors to marry and the rice to cook through perfectly.
Step 4: Cheese It Up and Serve
Once the initial baking is done, sprinkle the remaining cheese over the top and return the casserole to the oven for another 5 to 7 minutes. This melts the cheese into a bubbly, golden layer that makes the whole dish irresistibly good. Once melted, pull it out, let it sit for a few minutes, and get ready to dig in!
How to Serve Fajita Chicken Casserole Recipe
Garnishes
To elevate your fajita chicken casserole recipe, add fresh and vibrant garnishes like chopped cilantro, slices of avocado, or a dollop of guacamole. A few slices of jalapeño or a squeeze of lime juice can add a bright, fresh contrast that makes every bite sing.
Side Dishes
This casserole stands beautifully on its own, but pairing it with simple sides like a crisp green salad, homemade tortilla chips, or even Mexican street corn can create an even more memorable meal. The freshness of the sides balances the rich, creamy casserole perfectly.
Creative Ways to Present
If you want to switch things up, try serving scoops of the casserole over warm flour tortillas, turning it into an impromptu fajita taco night. Alternatively, load it into bell pepper halves for a colorful, portion-controlled presentation that’s as fun as it is delicious.
Make Ahead and Storage
Storing Leftovers
Your fajita chicken casserole recipe makes great leftovers. Place any uneaten portions in an airtight container and store them in the fridge for up to 4 days. The flavors deepen after resting, making your next meal just as tasty as the first.
Freezing
If you want to meal prep or save some for later, this casserole freezes well. Portion it into freezer-safe containers, leaving some space for expansion. It will keep in the freezer for up to 3 months. Just thaw overnight in the fridge before reheating.
Reheating
Reheat your fajita chicken casserole gently in the oven at 325°F (160°C) for about 20 minutes or until heated through. You can also use a microwave for convenience—cover loosely, and heat on medium power in intervals, stirring in between to avoid drying out the dish.
FAQs
Can I use fresh vegetables instead of frozen?
Absolutely! Feel free to use fresh diced onions and bell peppers. Just sauté them lightly before mixing into the casserole to soften and enhance their flavor.
Is it possible to make this recipe dairy-free?
Yes, you can substitute the sour cream with a dairy-free alternative and use vegan cheese or omit the cheese entirely for a dairy-free version. The casserole will still be flavorful thanks to the fajita seasoning and spices.
Can I use brown rice instead of instant rice?
You can, but keep in mind that brown rice typically requires a longer cooking time and more liquid. It’s best to pre-cook the brown rice beforehand to ensure the casserole cooks evenly.
How spicy is this fajita chicken casserole recipe?
The level of spice depends largely on the fajita seasoning and diced tomatoes with chilies. If you prefer milder flavors, choose a mild seasoning mix and tomatoes without chilies. You can always add spicy toppings separately if desired.
Can I double the recipe for a larger crowd?
Definitely! This recipe scales up well. Just use a larger baking dish or divide into multiple dishes. You may need to extend the baking time slightly to make sure it cooks thoroughly.

This Fajita Chicken Casserole Recipe is a heartfelt, easy-to-make dish that brings the fun, bold flavors of fajitas into a cozy, family-friendly casserole form. It’s perfect for busy weeknights and special gatherings alike. Give it a try—you might just find yourself making it on repeat!
