How to Make Mexican Chicken Casserole Recipe

Step 1: Prepare the Oven

Preheat your oven to 375°F (190°C) and lightly grease a baking dish to prevent sticking.

Step 2: Mix the Filling

In a large bowl, combine the shredded chicken, diced tomatoes with chilies, black beans, corn, salsa, sour cream, and taco seasoning. Stir until everything is evenly mixed.

Step 3: Create the First Layer

Spread half of the tortilla strips across the bottom of the baking dish. This layer will absorb the flavorful sauce.

Step 4: Add Chicken Mixture

Spoon half of the chicken mixture over the tortillas. Sprinkle a layer of cheddar and Monterey Jack cheese on top.

Step 5: Repeat the Layers

Add the remaining tortilla strips, followed by the rest of the chicken mixture. Finish with the remaining cheese on top.

Step 6: Bake the Casserole

Cover the dish with foil and bake for 20 minutes. Remove the foil and bake for another 10–15 minutes until the cheese is melted and bubbly.

Step 7: Garnish and Serve

Once baked, sprinkle fresh cilantro on top and let the casserole rest for about 5 minutes before serving.

Pro Tips for the Best Results

Always drain beans and corn to prevent a watery casserole.
Shred cheese fresh for better melting and flavor.
Let the casserole rest for a few minutes before cutting.
Add crushed tortilla chips on top for extra crunch.
