Cheesy Chicken Cordon Bleu Casserole

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish lightly with butter or non-stick spray.
In a large bowl, combine chopped chicken, diced ham, shredded Swiss cheese, cream of chicken soup, mayonnaise, Dijon mustard, garlic powder, onion powder, salt, and pepper. Mix until evenly combined.
Transfer the mixture to the prepared baking dish and spread it evenly.
In a small bowl, combine crushed crackers and melted butter. Sprinkle this mixture evenly over the top of the casserole.
Bake in the preheated oven for 25–30 minutes, or until the topping is golden and the casserole is heated through.
Remove from oven and let cool for 5 minutes before serving.
