Ingredients You’ll Need

For the Casserole

• 2 cups cooked chicken, shredded or diced – Chicken makes the casserole hearty and filling. Rotisserie chicken is a great shortcut that saves time.
• 1 packet taco seasoning – Taco seasoning gives the casserole its signature Tex-Mex flavor. Use homemade or store-bought, depending on your preference.
• 1 cup salsa – Salsa adds moisture, flavor, and a little heat. Mild, medium, or hot all work well.
• 1 can (15 ounces) black beans, drained and rinsed – Black beans add protein, fiber, and make the casserole even more satisfying.
• 1 cup corn kernels – Corn adds a touch of sweetness and a nice pop of texture. Fresh, frozen, or canned corn all work.
• 1 can (4 ounces) diced green chilies – Green chilies add mild heat and extra flavor without making the casserole overly spicy.
• 2 cups shredded Mexican cheese blend, divided – A Mexican cheese blend melts beautifully and creates a golden, bubbly topping.
• 3 cups crushed tortilla chips – Tortilla chips provide layers of crunch and soak up the flavorful sauce while baking.
• ½ cup sour cream – Sour cream makes the filling creamy and balances the bold taco seasoning.
• 2 green onions, sliced – Green onions add freshness and color before serving.
• 2 tablespoons chopped fresh cilantro – Cilantro adds a bright, fresh finish that pairs perfectly with the taco flavors.

How to Make Chicken Taco Casserole

Step 1: Preheat the oven

Preheat your oven to 350°F (175°C).

Lightly grease a 9×13-inch baking dish with cooking spray.

Step 2: Prepare the filling

In a large bowl, combine the chicken, taco seasoning, salsa, black beans, corn, diced green chilies, sour cream, and 1½ cups shredded cheese.

Mix until everything is evenly combined.

Step 3: Layer the casserole

Spread half of the crushed tortilla chips into the bottom of the prepared baking dish.

Spoon the chicken mixture over the chips and spread it into an even layer.

Top with the remaining crushed tortilla chips and sprinkle the remaining ½ cup shredded cheese evenly over the top.

Step 4: Bake

Cover loosely with aluminum foil and bake for 20 minutes.

Remove the foil and continue baking for another 10 to 15 minutes, or until the cheese is melted and bubbly.

Common Mistakes to Avoid

Using too much salsa

Too much salsa can make the casserole watery. Stick to the recommended amount for the best texture.

Adding all the chips too early

The top layer of tortilla chips stays crispier when added just before baking rather than mixing everything together.

Overbaking the casserole

Bake only until the cheese is melted and bubbly. Overbaking can dry out the chicken.

Forgetting the toppings

Fresh toppings like cilantro, green onions, guacamole, and sour cream add freshness and balance the rich, cheesy filling.

Not letting it rest

Let the casserole sit for 5 minutes before serving so the filling has time to set and is easier to scoop.
