Ingredients
- Cooked boneless skinless chicken breasts shredded: the protein base and keeps the dish hearty
- Olive oil: for sautéing vegetables and adding depth
- Green and red bell peppers sliced thin: they bring sweetness, crunch, and vibrant color
- Yellow onion sliced thin: adds savory undertones and softens during cooking
- Salt: enhances all the flavors
- Cream cheese softened: creates creamy richness and helps bind the casserole
- Shredded cheddar cheese: sharp and melty cheese for gooey goodness
- Fajita seasoning mix: homemade or store bought for that signature Tex Mex spice
- Freshly ground black pepper: adds a mild kick
- Fresh cilantro or parsley: bright garnish to finish the dish
Instructions
- Preheat the Oven:
- Set your oven to 350 degrees Fahrenheit. Lightly grease a 9 by 13 inch baking dish with cooking spray to prevent sticking. Shred the cooked chicken breasts and place them in a large mixing bowl. This warms you up for assembling the casserole.
- Sauté the Vegetables:
- Heat olive oil in a skillet over medium high heat. Add green and red bell pepper strips along with sliced onion. Sprinkle with salt and sauté for about 4 to 5 minutes, stirring frequently until vegetables soften but still retain some crunch. This step builds the flavor base.
- Combine Ingredients:
- Remove the skillet from heat and add the sautéed vegetables to the bowl with shredded chicken. In a separate bowl combine softened cream cheese, half the shredded cheddar cheese, fajita seasoning, salt, and black pepper. Mix well until creamy and spreadable.
- Mix Everything Together:
- Add the cream cheese mixture to the chicken and peppers bowl. Stir until all ingredients are thoroughly combined and evenly coated. This creates a flavorful filling.
- Assemble in Baking Dish:
- Transfer the mixture into the prepared baking dish, spreading it out evenly. Sprinkle the remaining cheddar cheese over the top. This will bake into a golden gooey crust.
- Bake Until Hot and Bubbly:
- Place the casserole in the preheated oven. Bake for 25 to 30 minutes until the cheese is melted and bubbly and the casserole is heated through. The baking melds all flavors together.
- Garnish and Serve:
- Remove from oven and sprinkle freshly chopped cilantro or parsley on top for a pop of color and freshness. Serve hot and enjoy this satisfying dish that tastes like a fiesta in every bite.
My favorite part is the fajita seasoning mix that brings the dish alive with bold flavor. I remember making this casserole for a casual family dinner and watching everyone go back for seconds. The cheese pull and spicy aroma brought smiles all around.
Storage Tips
Leftovers can be stored in an airtight container in the refrigerator for up to 4 days. Reheat gently to preserve moisture. This casserole also freezes nicely for up to 3 months when wrapped tightly, making it perfect for batch cooking.
Ingredient Substitutions
Swap chicken for turkey or beef if preferred or to switch up proteins. Use Monterey Jack or pepper jack cheese for a different cheesy flavor. For spice variations, add a pinch of cayenne or smoked paprika to the seasoning mix.
Serving Suggestions
Enjoy scooped on warm flour or corn tortillas for a fajita style wrap. Serve over rice or quinoa for a hearty bowl meal. Top with sour cream, salsa, or guacamole for added creaminess and freshness. Pair with a crisp garden salad or Mexican street corn salad for balance.
Let the casserole rest for a few minutes after baking to firm up for easier serving. Serve warm with your favorite toppings for maximum flavor.
