Preheat oven to 375°F (190°C) and grease a 9×13-inch baking dish.
In a large bowl, combine chicken, corn, cream cheese, sour cream, mayonnaise, cheese, cotija, cilantro, chili powder, garlic powder, cumin, lime juice, salt, and pepper until smooth.
Spread the creamy mixture evenly into the prepared baking dish and sprinkle remaining cotija cheese on top.
Mix crushed tortilla chips with Monterey Jack cheese and sprinkle evenly over the casserole.
Bake uncovered for 25–30 minutes, until hot, bubbly, and golden brown on top.
Let cool slightly, garnish with cilantro, lime wedges, and a drizzle of hot sauce.
