Begin layering by placing half of the crushed tortilla chips at the bottom of the prepared casserole dish. Over the chips, evenly spread half of the chicken mixture.

Layer the remaining tortilla chips on top of the chicken mixture, then cover with the rest of the chicken mixture. Sprinkle additional cheese on top if desired.

Cover the dish with aluminum foil and bake in the preheated oven for 35 minutes.

Optional: For more servings, double the recipe and use a 9×13 inch baking pan. Increase the cooking time to 45 minutes to ensure thorough heating and a bubbly finish. This adjustment is perfect for ensuring leftovers.
