Ingredients
- 1 red onion , diced (for a milder flavor, you can use a yellow or white onion)
- 1 red bell pepper, chopped (adds sweetness and vibrant color)
- 1 orange bell pepper, chopped (feel free to substitute with yellow or green bell pepper)
- 3 cups cooked shredded chicken (rotisserie chicken works perfectly for convenience, or boil and shred chicken breasts)

- 2 tbsp taco seasoning (use your favorite store-bought blend or homemade seasoning)
- 1 cup Monterey Jack cheese, shredded (or a Mexican blend for extra flavor)

Instructions
- Step 1: Prepare Your Oven. Preheat your oven to 350 degrees F (175 degrees C). This ensures your casserole bakes evenly and cooks through perfectly.
- Step 2: Combine the Filling. In a large mixing bowl, add the diced red onion, chopped red bell pepper, chopped orange bell pepper, shredded cooked chicken, softened cream cheese, and taco seasoning. Ensure the cream cheese is truly softened to make mixing easier and prevent lumps. Add 1/2 cup of the shredded Monterey Jack cheese to the mixture. Stir all the ingredients together thoroughly until everything is well combined and the chicken and vegetables are coated in the creamy, seasoned mixture.
- Step 3: Bake to Perfection. Lightly spray a 9×13 inch baking dish (or similar size) with nonstick cooking spray. Transfer the fajita casserole mixture into the prepared baking dish and spread it out evenly using a spatula or the back of a spoon. Sprinkle the remaining 1/2 cup of Monterey Jack cheese over the top of the casserole. Cover the baking dish tightly with aluminum foil and bake in the preheated oven for 35 minutes. After 35 minutes, carefully remove the foil and continue to bake for an additional 14 minutes, or until the cheese is melted, bubbly, and slightly golden brown.
- Step 4: Rest and Serve. Once baked, remove the casserole from the oven and let it rest for 5-10 minutes. This allows the flavors to meld and the casserole to set, making it easier to serve. Garnish with fresh cilantro, sliced avocado, or a dollop of sour cream if desired, and enjoy!

Tips for a Perfect Fajita Casserole
Achieving a perfectly delicious fajita casserole is easy with a few key tips:
- Use Cooked Chicken: Pre-cooked shredded chicken (like rotisserie chicken) saves a lot of time and ensures the chicken is tender. If using raw chicken, make sure to cook and shred it before mixing with the other ingredients.
- Soften the Cream Cheese: For a smooth, lump-free mixture, it’s crucial that your cream cheese is at room temperature and well softened. This allows it to blend seamlessly with the other ingredients.
- Don’t Overmix: While you want everything well combined, avoid overmixing which can break down the chicken too much.
- Flavorful Taco Seasoning: A good quality taco seasoning makes all the difference. You can use store-bought or make your own blend with chili powder, cumin, paprika, garlic powder, onion powder, and a pinch of cayenne for heat.
- Even Spread: Ensure the casserole mixture is spread evenly in the baking dish to allow for consistent cooking and browning.
- Resting Time: Letting the casserole rest for a few minutes after baking helps it set, making for cleaner slices and a more enjoyable texture.
Serving Suggestions for Your Fajita Casserole
This Baked Chicken Fajita Casserole is a complete meal on its own, but it truly shines when served with a few complementary sides and toppings. Here are some ideas to elevate your dining experience:
- Warm Tortillas: Soft flour or corn tortillas are perfect for scooping up the savory casserole filling.
- Rice and Beans: A classic pairing! Serve with a side of fluffy Mexican rice, cilantro-lime rice, or hearty black beans.
- Fresh Toppings: Offer a selection of fresh garnishes to add texture and brightness:
- Diced avocado or guacamole
- Sour cream or Greek yogurt
- Fresh chopped cilantro
- Salsa or pico de gallo
- Lime wedges for a squeeze of citrus
- Sliced jalapeños (fresh or pickled) for an extra kick
- Crisp Salad: A simple green salad with a light vinaigrette can cut through the richness of the casserole.
- Corn on the Cob: Sweet corn, either on the cob or as a simple salad, makes a great seasonal addition.
Variations & Customizations
One of the best things about casseroles is how adaptable they are! Feel free to get creative with this fajita casserole base:
- Different Proteins:
- Beef Fajita Casserole: Use cooked, shredded beef or ground beef seasoned with taco seasoning.
- Shrimp Fajita Casserole: Quickly sauté shrimp with fajita seasoning before adding to the mix.
- Pork Fajita Casserole: Slow-cook pork shoulder and shred it for a rich alternative.
- Extra Veggies: Add more bell peppers (green, yellow), corn, black beans, or even diced zucchini for added nutrition and texture.
- Spice It Up: Incorporate diced jalapeños or serrano peppers into the mix, add a pinch of cayenne pepper to the taco seasoning, or drizzle with hot sauce before serving.
- Cheese Swaps: Experiment with other cheeses like Colby Jack, cheddar, or a smoky chipotle cheddar for different flavor profiles.
- Low-Carb Option: Serve the casserole over cauliflower rice, in lettuce wraps, or simply as is, omitting tortillas for a lower carbohydrate meal.
- Creamier Texture: For an even creamier casserole, you can add a small amount of cream of chicken soup or a splash of milk to the mixture.
Make Ahead & Storage Tips
This fajita casserole is excellent for meal prepping or enjoying as leftovers:
- Make Ahead: You can assemble the entire casserole (up to the point of baking, before adding the top layer of cheese) and store it covered in the refrigerator for up to 24 hours. When ready to bake, add the final cheese layer and add an extra 10-15 minutes to the covered baking time to ensure it heats through.
- Storage: Store any leftover casserole in an airtight container in the refrigerator for up to 3-4 days.
- Reheating: Reheat individual portions in the microwave until warm, or warm larger portions in the oven at 300°F (150°C) until heated through. If reheating in the oven, you might want to cover it with foil to prevent drying out.
- Freezing: This casserole freezes well!
- To Freeze Unbaked: Assemble the casserole in a freezer-safe baking dish (preferably an aluminum foil pan for easy transfer). Cover tightly with plastic wrap, then with aluminum foil. Freeze for up to 3 months. When ready to bake, thaw in the refrigerator overnight, then bake as directed, potentially adding a little extra time.
- To Freeze Baked: Let the baked casserole cool completely. Cut into individual servings or wrap the entire casserole tightly in plastic wrap and then foil. Freeze for up to 3 months. Thaw in the refrigerator and reheat in the oven or microwave.
Frequently Asked Questions (FAQs)
Q: Can I use raw chicken for this recipe?
A: It’s highly recommended to use cooked chicken for this recipe. Raw chicken would need to be cooked through before mixing with the other ingredients to ensure it’s fully cooked and safe to eat within the casserole’s baking time. Using pre-cooked chicken, like rotisserie chicken, significantly speeds up the preparation.
Q: What kind of taco seasoning should I use?
A: You can use any store-bought taco seasoning blend you prefer. Alternatively, you can make your own by combining chili powder, cumin, paprika, garlic powder, onion powder, oregano, and a pinch of salt and pepper. This allows you to control the spice level and sodium content.
Q: Can I make this casserole spicier?
A: Absolutely! To add more heat, you can include finely diced jalapeños or serrano peppers in the vegetable mixture, add a dash of cayenne pepper to your taco seasoning, or serve with your favorite hot sauce on the side.
Q: Is this recipe suitable for a low-carb diet?
A: Yes, this casserole can easily be adapted for a low-carb diet. The main ingredients (chicken, vegetables, cream cheese, and Monterey Jack cheese) are naturally low in carbs. Simply serve it without tortillas, perhaps over a bed of cauliflower rice or in large lettuce cups.
Q: Can I use different types of bell peppers?
A: Yes, you can use any combination of bell peppers you have on hand. Red, orange, and yellow bell peppers offer a sweeter flavor and vibrant color, while green bell peppers have a slightly more bitter and earthy taste that still works well.
