Mustard-roasted Potatoes

This is one of those recipes that I’ve had bookmarked for more than a year (a! year!) and never made, despite knowing it would be nothing short of awesome and that my husband, who is a Dijon and also a roasted potato fanatic, would adore it. Obviously, I do not love him at all, right?
