I like preparing this chicken fajita casserole when I want the bold flavors of fajitas in an easy baked dish. It combines tender chicken, colorful bell peppers, and warm spices with a creamy base that bakes into a satisfying casserole. I find that it captures the classic fajita taste while being simple to prepare and perfect for a comforting family meal.
Why You’ll Love This Recipe
I enjoy this recipe because it delivers strong fajita flavor without the need to cook everything separately on the stove. I simply combine the ingredients and let the oven do most of the work. The chicken becomes tender, the peppers soften beautifully, and the spices blend into a rich and savory dish. I also like how versatile it is because it pairs well with rice, tortillas, or a fresh salad.
Ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
2 cups cooked chicken, shredded or diced
1 red bell pepper, sliced
1 green bell pepper, sliced
1 small onion, sliced
1 cup shredded cheddar cheese
1/2 cup cream cheese, softened
1/2 cup sour cream
1 tablespoon olive oil
1 teaspoon chili powder
1 teaspoon cumin
1/2 teaspoon paprika
1/2 teaspoon garlic powder
1/2 teaspoon salt
1/4 teaspoon black pepper
1/2 cup diced tomatoes with green chilies
Directions
I start by preheating the oven to 375°F (190°C) and lightly greasing a baking dish. In a large mixing bowl, I combine the cooked chicken, sliced bell peppers, and onions.
In another bowl, I mix the cream cheese, sour cream, olive oil, chili powder, cumin, paprika, garlic powder, salt, and black pepper until smooth. I add the diced tomatoes with green chilies and stir until everything is well combined.
I pour this creamy mixture over the chicken and vegetables and mix everything together until evenly coated. I transfer the mixture into the prepared baking dish and spread it evenly.
Next, I sprinkle the shredded cheddar cheese across the top. I place the dish in the oven and bake it for about 25 to 30 minutes until the casserole is hot and bubbly and the cheese is melted.
I let it cool slightly before serving so the flavors settle and the casserole slices easily.

Variations
I sometimes add sliced mushrooms or corn to give the casserole extra texture. When I want a little heat, I mix in diced jalapeños or extra chili powder. I also like replacing cheddar with a Mexican cheese blend or pepper jack for a stronger flavor. Occasionally, I add cooked rice to the mixture to turn the dish into a more filling one-pan meal.
storage/reheating
I store leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, I warm individual portions in the microwave for a few minutes until heated through. I can also reheat the casserole in the oven at 350°F (175°C) for about 15 minutes. This dish can be frozen for up to 2 months, and I thaw it overnight in the refrigerator before reheating.
FAQs
Can I use raw chicken instead of cooked chicken?
I prefer using cooked chicken for convenience, but raw diced chicken can be used if I cook it briefly in a skillet before adding it to the casserole.
Can I make this casserole ahead of time?
I often assemble the casserole a day in advance and store it in the refrigerator. When ready to cook, I simply bake it as directed.
What can I serve with chicken fajita casserole?
I like serving it with warm tortillas, rice, or a fresh salad to complete the meal.
Can I make this dish low-carb?
I find that the recipe is naturally low in carbohydrates, especially when I serve it on its own or with a simple vegetable side.
Can I substitute the sour cream?
I sometimes replace sour cream with plain Greek yogurt, which gives the casserole a similar creamy texture with a slightly tangy flavor.

I enjoy making chicken fajita casserole because it transforms classic fajita flavors into a simple and comforting baked dish. The combination of tender chicken, peppers, spices, and creamy cheese makes it rich and satisfying. It is an easy recipe I like preparing when I want a flavorful meal that requires minimal effort.
