How to Make Fajita Chicken Casserole Recipe
Step 1: Prepare Your Oven and Chicken
Start by heating your oven to 375°F (190°C). While it’s warming up, heat olive oil in a large skillet over medium-high heat. Add the chicken strips and cook them until they’re golden on the outside and fully cooked through, about 5 to 7 minutes. This step ensures your chicken remains juicy and tender, setting a delicious foundation for the casserole.
Step 2: Season the Chicken
Next, sprinkle the fajita seasoning mix over the hot chicken in the skillet and stir well, making sure every strip is coated with that spicy, flavorful blend. The seasoning mix is key to bringing the classic fajita zest into every bite of this casserole.
Step 3: Combine the Ingredients
In a large bowl, toss together the seasoned chicken, sliced red and green bell peppers, sliced yellow onion, 1 cup of shredded cheddar cheese, sour cream, drained diced tomatoes with green chilies, garlic powder, and onion powder. Mixing these ingredients well creates a perfect balance of creamy, spicy, and fresh textures that will bake beautifully.
Step 4: Assemble the Casserole
Pour your mixed filling into a greased 9×13 inch (23×33 cm) baking dish, spreading it out evenly. Then, sprinkle the remaining cup of cheddar cheese on top. This layer melts into a golden, bubbly crust that makes this casserole irresistible.
Step 5: Bake to Perfection
Cover the dish with aluminum foil and bake for 20 minutes to allow the flavors to meld and the filling to heat through. After 20 minutes, uncover the casserole and bake for an additional 10 minutes until the cheese topping is bubbly and has turned a beautiful golden brown. Let the casserole cool for a few minutes once it’s out of the oven to make it easier to serve and enjoy its full flavor.
How to Serve Fajita Chicken Casserole Recipe
Garnishes
Adding fresh cilantro as a garnish brings a lively herbal note that brightens the rich layers of flavor. Serve each portion with lime wedges that offer a tangy, citrus kick when squeezed on top, perfectly complementing the spices.
Side Dishes
This casserole pairs wonderfully with simple sides like a crisp green salad, fluffy Mexican rice, or even some warm, soft tortillas for scooping. These sides add balance to the rich, cheesy casserole and round out a satisfying meal.
Creative Ways to Present
For a fun twist, serve the casserole in individual ramekins or small cast iron skillets to add a rustic touch. You can also layer in some sliced avocado or dollop with guacamole for creaminess and added color. Presentation ideas like these turn the dish into a festive centerpiece at any dinner gathering.
Make Ahead and Storage
Storing Leftovers
Store any leftovers in an airtight container in the refrigerator for up to 3 days. The flavors often deepen after resting, making for a delicious next-day meal.
Freezing
This Fajita Chicken Casserole Recipe freezes very well. Transfer cooled portions into freezer-safe containers and freeze for up to 3 months. It’s perfect for prepping meals ahead of time or saving for busy weeknights.
Reheating
Reheat leftovers in a microwave or oven until warmed through. If using an oven, cover loosely with foil to prevent the cheese from burning, reheating at 350°F (175°C) for about 15-20 minutes. This keeps the casserole moist and gooey.
FAQs
Can I use other types of cheese for this Fajita Chicken Casserole Recipe?
Absolutely! While cheddar cheese is traditional for its melting quality and sharp flavor, you can experiment with Monterey Jack, Pepper Jack, or even a Mexican cheese blend to add different textures and spice levels.
Is it possible to make this casserole vegetarian?
Yes. Replace the chicken with hearty vegetables like mushrooms, zucchini, or black beans. Adjust the seasoning slightly to enhance the veggie flavors, and you’ll still get that fajita flair without meat.
Can I prepare the casserole a day in advance?
Definitely! You can assemble the casserole ahead of time and keep it covered in the refrigerator overnight. Just add a few extra minutes to the baking time if it’s cold from the fridge.
What’s the best way to slice the chicken for fajitas?
Slicing the chicken into thin strips across the grain ensures tenderness and quick cooking, which is perfect for maintaining that signature fajita texture in the casserole.
Can I use fresh tomatoes instead of canned diced tomatoes with green chilies?
You can substitute fresh tomatoes finely chopped, but be mindful of added heat from the canned chilies. You might want to add a touch of chili powder or jalapeño separately to replicate the same spicy flavor.

This Fajita Chicken Casserole Recipe is truly a joyful celebration of flavor, simplicity, and convenience all baked into one dish.
