Heat butter in a large nonstick skillet over medium/high heat.
Whisk in the flour and stir while cooking for 1 minute.
Whisk in the milk, cream, and wine slowly, one cup at a time, whisking constantly. Bring to a simmer.
Quickly add the macaroni, dijon, and salt and pepper, stirring constantly while cooking, about 6 minutes, or until al dente. Be sure to scrape the bottom of the pan while you cook.
Turn off the heat and stir in the cheese. I stirred in about half at a time to make sure none spilled over the sides.
In a small bowl, combine the melted butter, breadcrumbs, and parmesan.
Pour the breadcrumb mixture over the mac and cheese and broil for 2 minutes or until they are golden and toasted. Top with the chives and serve hot.
Enjoy!
