How to Make Fajita Chicken Casserole Recipe
Step 1: Preheat and Prep
Start by heating your oven to 350 degrees Fahrenheit and lightly greasing a baking dish. This ensures everything cooks evenly and your casserole releases easily when it’s done.
Step 2: Mix the Filling
In a large bowl, combine your shredded cooked chicken, instant rice, cream of chicken soup, sour cream, frozen vegetable blend, undrained diced tomatoes with chilies, chicken broth, fajita seasoning, and half of the shredded cheese. Stir everything together until all the ingredients are well incorporated and evenly coated with that creamy, spicy sauce. This mixture is where all the exciting flavors come to life.
Step 3: Bake the Casserole
Pour the mixture into your prepared baking dish, spreading it out evenly. Pop it into the oven and bake for about 30 minutes, allowing the rice to cook and absorb all those wonderful juices. Then, pull it out, sprinkle the remaining cheese on top, and return it to the oven for an additional 5 to 10 minutes until the cheese is beautifully melted and bubbly.
Step 4: Let It Rest and Serve
Once out of the oven, let your fajita chicken casserole sit for a few minutes. This helps the layers settle, making it easier to slice and serve with all those vibrant textures intact. Now, it’s ready to delight everyone at the table!
How to Serve Fajita Chicken Casserole Recipe
Garnishes
A fresh topping can elevate this dish from great to unforgettable. Consider sprinkling chopped cilantro, a dollop of sour cream, sliced avocado, or even some fresh lime wedges. These bright additions bring refreshing contrasts and boost the authentic fajita vibe.
Side Dishes
Keep the meal balanced by adding simple sides like a crisp green salad, warm tortillas, or Spanish rice. A side of black beans or corn on the cob can also complement the casserole’s rich, zesty flavors perfectly.
Creative Ways to Present
For a fun twist, serve the fajita chicken casserole over crispy tortilla chips as a nacho-style bake, or spoon it into hollowed-out bell peppers. You can even layer it in a casserole dish with extra toppings for a festive, family-style presentation.
Make Ahead and Storage
Storing Leftovers
This fajita chicken casserole keeps beautifully in the fridge for up to four days. Store leftovers in an airtight container to preserve moisture and flavor, so you can enjoy it for lunches or quick dinners later in the week.
Freezing
You can freeze this casserole either before or after baking. Wrap it tightly with foil or plastic wrap and freeze for up to three months. Thaw in the fridge overnight before reheating to keep that fresh, just-cooked taste.
Reheating
To reheat, warm individual portions in the microwave or cover the casserole dish with foil and bake at 350 degrees Fahrenheit until heated through. Adding a little extra shredded cheese on top before reheating can make it feel like a freshly made meal.
FAQs
Can I use fresh vegetables instead of frozen?
Absolutely! Fresh diced onions and bell peppers add a wonderful crunch and bright flavor. Just sauté them lightly before adding to the mixture to soften, or increase the baking time slightly to ensure they cook through.
Is it possible to make this casserole dairy-free?
Yes, you can swap out the cream of chicken soup for a dairy-free alternative, use a plant-based sour cream, and choose a dairy-free cheese blend. The fajita seasoning and vegetables will still provide tons of flavor.
Can this recipe be made with leftover rotisserie chicken?
Using leftover rotisserie chicken is actually a perfect shortcut! It’s already cooked and seasoned lightly, which complements the fajita spices nicely and saves prep time.
How spicy is this casserole? Can it be adjusted?
Thanks to the diced tomatoes with chilies and seasoning packet, it has a mild to moderate spicy kick. You can easily reduce the heat by using mild diced tomatoes or less fajita seasoning, or boost it by adding extra chili powder or jalapeños.
Can I add other proteins or vegetables to this casserole?
Definitely! Feel free to mix in cooked sausage, chorizo, or even shrimp for different protein options. Extra vegetables like corn, black beans, or zucchini will also work well and add more color and nutrition.

Notes
- You can use cooked rotisserie chicken to save time on shredding chicken breasts yourself.

- Instant rice cooks perfectly in the casserole with the chicken broth, but regular rice can be used if pre-cooked.
- For a lower-fat version, substitute sour cream with Greek yogurt and reduce the cheese amount.
- This casserole can be prepared ahead and refrigerated before baking—add an extra few minutes to the baking time if baking straight from the fridge.
