How to Make Chicken Taco Casserole

First assemble the following ingredients:

Cooked shredded chicken mixed with fajita seasoning (3 cups) – Provides a lean, flavorful protein base that perfectly absorbs the rich spices and sauces, serving as the heart of the casserole.
8” tortillas (4) – Cut into pieces and layered throughout, tortillas offer a soft, chewy texture that mimics the classic taco shell in a more casserole-friendly form.
Red enchilada sauce (20 oz) – Infuses the dish with its deep, smoky flavor, coating the ingredients in a savory sauce that ties the casserole together.
Black beans (12 oz) – Add a hearty, fibrous element to the casserole, bringing in a creamy texture and a mild, earthy flavor that complements the spicier ingredients.
Mexican cheese blend (2 cups) – Melts into a gooey, stringy layer of deliciousness, adding a rich, cheesy goodness that blankets the casserole in comfort.
Yellow onion (½ cup) – Offers a sweet, aromatic base that enhances the overall savoriness of the dish, softening into tender translucence as it bakes.
Red bell pepper (1) – Adds a sweet, slightly tangy crunch and a pop of vibrant color, contributing to the dish’s visual appeal and nutritional value.
Green bell pepper (1) – Provides a slightly bitter counterpoint to the sweeter red bell pepper, adding complexity and freshness to the mix of flavors.
Jalapeno (1) – Delivers a spicy kick that punctuates the casserole with heat, which can be adjusted according to your spice preference.
Green onion (1/3 cup) – Sprinkled on top before serving, green onions add a mild, crunchy bite and a burst of color, finishing the dish with a fresh, oniony zing.

Tips and Tricks to Perfect Mexican Chicken Casserole

Use Rotisserie Chicken: For a quick and easy shortcut, use shredded rotisserie chicken. It’s flavorful, moist, and can save a lot of prep time.

Season Generously: Don’t skimp on the taco seasoning for the chicken. Whether homemade or store-bought, a robust seasoning mix will infuse the casserole with that signature taco flavor.

Layer Wisely: Start with a layer of crushed tortilla chips or tortillas at the bottom to absorb the juices and provide a satisfying crunch. Layer your ingredients evenly to ensure every bite is packed with flavor.

Choose Your Cheese Wisely: A blend of cheeses such as cheddar for sharpness and Monterey Jack for meltiness creates a perfect, gooey topping. Consider adding a layer of cheese both in the middle and on top for extra cheesiness.

Add Freshness: Top the baked casserole with fresh ingredients like chopped tomatoes, green onions, cilantro, or avocado for a burst of freshness and a contrast to the warm, spicy flavors.

Customize Your Toppings: Serve with a variety of toppings on the side, such as sour cream, salsa, guacamole, and hot sauce, allowing everyone to customize their serving according to their taste preferences.

Don’t Overbake: Keep an eye on the baking time to prevent the edges from becoming too hard or the cheese from burning. The casserole is done when it’s bubbly and golden brown.

Let It Rest: Allow the casserole to rest for a few minutes after removing it from the oven. This helps the layers set, making it easier to slice and serve.

Experiment with Layers: Beyond chicken and cheese, consider adding layers of black beans, corn, diced green chiles, or sautéed onions and peppers for more depth and variety in your casserole.

Make It Ahead: Assemble the casserole ahead of time and refrigerate. Just add a few minutes to the baking time if you’re starting from cold. It’s a great way to make meal prep easier for busy days.
