Ingredients You’ll Need
Getting this Chicken Fajita Casserole Recipe just right requires a handful of simple ingredients that work together beautifully. Each one brings its own magic to the dish, from the juicy chicken and vibrant peppers to the creamy cheeses and fluffy rice that soak up every bit of flavor.
- 1 1/2 pounds chicken breast: Cut into bite-sized pieces to ensure tender, juicy bites throughout the casserole.
- 3 Tablespoons olive oil (divided): Used to cook the chicken and sauté the vegetables, adding richness and a beautiful golden sear.
- 1 packet fajita seasoning: The key seasoning blend that spices up the chicken with classic Tex-Mex flair.
- 1 red bell pepper (diced): Adds sweet, vibrant color and a crisp texture.
- 1 green bell pepper (diced): Offers a slightly more bitter note to balance the mix.
- 1 yellow bell pepper (diced): Brings a sunny brightness and subtle sweetness.
- 1 yellow onion (diced): Adds depth with its mild sharpness and aromatic flavor.
- 1 cup sour cream: Makes the casserole beautifully creamy and tangy.
- 1 8-ounce block cream cheese (softened): Enhances the smooth texture and adds a luscious richness.
- 1 cup instant rice (Minute Rice): Absorbs the flavorful liquids and keeps the dish hearty and filling.
- 1 1/4 cups chicken stock: Keeps everything moist while infusing savory notes throughout the casserole.
- 2 cups shredded Colby Jack cheese (divided): Melts blissfully on top and throughout for cheesy, gooey goodness.

How to Make Chicken Fajita Casserole Recipe
Step 1: Season the chicken
Begin by preheating your oven to 375°F (190°C). In a large bowl, coat the bite-sized chicken breast pieces with 1 tablespoon of olive oil and the fajita seasoning packet. Toss thoroughly until every piece is evenly covered in that vibrant, spicy seasoning—this step ensures the chicken will be bursting with flavor after cooking.
Step 2: Cook the chicken
Heat another tablespoon of olive oil in a skillet over medium-high heat. Add your seasoned chicken pieces and cook them for 5-7 minutes until browned and cooked through. The sizzling chicken gets a nice sear that locks in juices and flavor. Once cooked, remove the chicken from the skillet and set it aside—don’t rush, the caramelization is worth it.
Step 3: Sauté the vegetables
In the same skillet, add the final tablespoon of olive oil. Toss in the diced red, green, and yellow bell peppers along with the yellow onion. Sauté for 5-6 minutes until they soften slightly but still retain a little bite and their gorgeous colors. This mix adds a lovely sweetness and crunch to balance the tender chicken.
Step 4: Combine creamy mixture
In a large mixing bowl, blend the softened cream cheese and sour cream until creamy and smooth. Stir in the chicken stock, instant rice, 1 cup of shredded Colby Jack cheese, the cooked chicken, sautéed vegetables, salt, and black pepper. Mix everything carefully until combined. It might look a bit liquidy now, but the rice will soak up all those delicious juices as it bakes.
Step 5: Assemble and bake
Lightly grease a 9×13-inch baking dish to prevent sticking. Pour the creamy chicken and vegetable mixture into the dish, spreading it out evenly. Sprinkle the remaining 1 cup of shredded Colby Jack cheese over the top for a golden, bubbly finish. Cover the dish tightly with aluminum foil to lock in moisture and pop it in the oven.
Step 6: Bake to perfection
Bake the casserole for 20 minutes, then carefully remove the foil and bake for an additional 10-15 minutes. This step lets the cheese melt into a delectably gooey layer with just the right amount of browning. When it’s bubbling and golden, your Chicken Fajita Casserole Recipe is ready to come out.
Step 7: Rest and serve
Allow your casserole to sit for 5 minutes before serving. This helps the layers set nicely so you can easily scoop out perfect portions full of savory chicken, cheesy rice, and colorful veggies in every bite.
How to Serve Chicken Fajita Casserole Recipe
Garnishes
Top this casserole with a sprinkle of fresh chopped cilantro or green onions for a fresh, herbal pop that brightens every bite. Adding a dollop of sour cream, sliced avocado, or a squeeze of lime juice creates lovely creamy and tangy contrasts to the warm, cheesy layers already in the dish.
Side Dishes
This Chicken Fajita Casserole doesn’t need much to shine but pairing it with a crisp green salad or simple black beans adds nutritious balance and extra texture. For a bit of freshness and crunch, serve with tortilla chips or a side of guacamole for that classic Tex-Mex twist.
Creative Ways to Present
Bring some fun to the table by serving the casserole in individual ramekins or small cast iron skillets for personal portions that stay warm longer. Drizzle with some homemade salsa or hot sauce for those who love an extra kick, or sprinkle toasted pepitas on top for surprising nuttiness and crunch.
Make Ahead and Storage
Storing Leftovers
Once cooled, store any leftovers in an airtight container in the fridge for up to 3 days. The flavors actually deepen over time, making for a delicious next-day meal. Just be sure to cover well to keep the casserole moist and prevent the cheese from drying out.
Freezing
This Chicken Fajita Casserole Recipe freezes beautifully. Prepare the casserole as directed, but instead of baking, cover tightly with foil and place it in the freezer for up to 2 months. When ready to enjoy, thaw overnight in the fridge before baking as instructed to retain the best texture.
Reheating
Reheat leftovers in the oven at 350°F (175°C) for about 15-20 minutes, covered to keep moisture locked in. You can also microwave individual portions for 2-3 minutes, stirring halfway through for even heating. The cheese gets wonderfully melty again with just a little reheating love.
FAQs
Can I use brown rice instead of instant rice in this Chicken Fajita Casserole Recipe?
You can substitute brown rice, but keep in mind it requires a longer cooking time and more liquid. You might need to adjust the chicken stock amount and bake time to ensure the rice cooks fully and the casserole doesn’t dry out.
Is this casserole spicy?
The spice level depends on the fajita seasoning you use. Most fajita seasonings are mildly spiced, but if you want more heat, you can add a pinch of cayenne or use a spicier fajita mix. For milder tastes, choose a seasoning blend with less chili powder.
Can I make this recipe vegetarian?
Absolutely! Simply swap the chicken for extra vegetables like mushrooms, zucchini, or black beans. You can use vegetable stock instead of chicken stock to keep the flavors rich and satisfying.
What cheese works best for this Chicken Fajita Casserole Recipe?
Colby Jack is perfect because it melts smoothly and has a mild, slightly tangy flavor that complements the fajita spices. However, you can experiment with Monterey Jack, cheddar, or a Mexican cheese blend for delicious variations.
Can I use fresh fajita seasoning instead of a packet?
Yes! A homemade fajita seasoning with chili powder, cumin, garlic powder, onion powder, paprika, and a pinch of salt and pepper yields fantastic results. Making your own allows you to adjust flavors to your preference.
