This elegant restaurant-style recipe features tender pork tenderloin smothered in a rich and creamy mustard sauce. The pork is first seared in a hot skillet to create a crispy crust, then finished in the oven until it's cooked through. The sauce is made with Dijon mustard, heavy cream, white wine, and chicken broth, and is simmered until it's thick and velvety. The result is a decadent and flavorful dish that's perfect for a special occasion or a romantic dinner for two.
