1-Start by preheating your oven to 375°F and greasing a 13×9 inch baking dish to ensure easy cleanup and even cooking. Next, layer the cooked chicken evenly in the dish as your base for this comforting meal. Follow by arranging the Swiss cheese slices over the chicken to add that creamy, nutty layer.

2-In a large bowl, mix the cream of chicken soup, milk, mayonnaise, poultry seasoning, garlic powder, onion powder, salt, and black pepper until well combined, then pour it evenly over the cheese and chicken. In another bowl, combine the seasoned stuffing mix, shredded parmesan cheese, and melted butter, mixing until coated, and sprinkle it over the top for a crispy finish. Finally, bake for 30 to 35 minutes until the cheese bubbles and the topping turns golden brown, then garnish with chopped parsley if you like.
