Gradually add the grated cheddar cheese, stirring until it melts into a smooth sauce.
Pour the cheese sauce over the macaroni and seafood mixture. Stir to combine.
Season with salt and pepper to taste.
Transfer everything to a well-buttered baking dish.
Sprinkle mozzarella cheese on top, followed by panko bread crumbs.
