Ingredients

• One pound cooked boneless skinless chicken breasts shredded: the protein base that keeps it hearty
• One tablespoon olive oil: essential for sautéing the vegetables with a silky finish
• One small green bell pepper sliced thin: adds fresh crunch and color
• One small red bell pepper sliced thin: brings sweetness and vibrancy
• One small yellow onion thinly sliced: adds natural sweetness and depth
• Quarter teaspoon salt: enhances all the flavors without overpowering
• Eight ounces cream cheese softened and cut into pieces: creates a rich and creamy texture
• Eight ounces shredded cheddar cheese: delivers gooey, melty cheesy goodness
• One and a half tablespoons fajita seasoning mix: the spice blend that defines the fajita flavor
• Salt and freshly ground black pepper to taste: personal seasoning adjustments
• Fresh cilantro or parsley for garnish: adds fresh herbal brightness and color

Instructions

Preheat the Oven:

Preheat your oven to 350 degrees Fahrenheit. Lightly grease a 9 by 13 inch baking dish with cooking spray to prevent sticking. Shred cooked chicken breasts and place them into a large mixing bowl to have them ready for combining later.

Sauté the Vegetables:

Warm olive oil in a skillet over medium high heat until shimmering. Add the thin strips of green and red bell peppers along with the sliced yellow onion. Season with a quarter teaspoon of salt and cook for 4 to 5 minutes, stirring often until the vegetables soften but retain a slight crispness. This step helps release the natural sweetness and deepens their flavor.

Combine Ingredients:

Remove the skillet from the heat and transfer the sautéed vegetables into the bowl with shredded chicken. In a separate large bowl, mix the softened cream cheese, half of the shredded cheddar cheese, fajita seasoning mix, salt, and black pepper. Stir the mixture until completely blended and smooth.

Mix Everything Together:

Pour the creamy cheese mixture into the bowl with chicken and vegetables. Fold gently until all the ingredients are evenly incorporated into a cohesive filling.

Assemble in Baking Dish:

Transfer the combined chicken mixture into the prepared baking dish. Sprinkle the remaining shredded cheddar cheese evenly on top to build a golden cheesy crust.

Bake Until Hot and Bubbly:

Place the casserole in your preheated oven and bake for 25 to 30 minutes. Watch for the cheese to melt fully and turn bubbly with slight browning on the edges, signaling it is ready.

Garnish and Serve:

Remove the casserole from the oven and sprinkle freshly chopped cilantro or parsley over the top for a lively finish. Serve warm and enjoy each rich, comforting bite of your Chicken Fajitas Casserole.

My favorite ingredient here is the fajita seasoning. It’s where the magic happens, turning simple chicken and veggies into a fiesta of flavors. Making this recipe always reminds me of cozy family dinners where laughter and good food go hand in hand, and everyone gathers around with happy appetites.

Storage Tips

Store leftover casserole in an airtight container and keep refrigerated for up to four days to maintain freshness. Reheat gently in the oven or microwave to bring back that gooey cheese texture without drying it out.

Ingredient Substitutions

If you want to change things up, try swapping cheddar for Monterey Jack or pepper jack cheese for a little kick. Ground turkey or beef can replace chicken if you prefer a different protein. You can also add zucchini or corn for extra veggies.

Serving Suggestions

This casserole is delicious on its own but pairs wonderfully with warm flour or corn tortillas for making handheld fajita wraps. Spoon it over fluffy white rice or quinoa for a heartier meal. Fresh toppings like sour cream, guacamole, or salsa add creaminess and brightness to every bite.

Let the casserole rest for five minutes before serving to help it set. Enjoy warm with your favorite toppings.
