it for chopped parsley or leave the herbs out and finish with a sprinkle of dried Italian seasoning on just half the dish.
To lighten things up a bit, use 1 cup heavy cream and 1 cup whole milk instead of all cream, knowing it will be slightly less rich but still comforting. For extra cheesiness, mix in 1/2 cup shredded mozzarella or mild cheddar with the Parmesan in the pour-over. If you need to prep ahead, assemble the dish up to the point of baking, cover, and refrigerate
