The combination of mustards in this recipe produces an especially piquant sauce to serve with the pork.


  • 1 tablespoon olive oil

  • 2 pork tenderloins (¾ - 1 pound each), trimmed

  • Coarse salt and ground pepper

  • ¼ cup whole-grain mustard

  • 2 tablespoons Dijon mustard

  • 2 tablespoons reduced-fat sour cream


  1. Heat oil in a large skillet over high heat. Season pork with salt and pepper; transfer to skillet and cook, turning, until browned all over, 5 to 10 minutes. Reduce heat to medium-low and cover skillet; cook pork, turning occasionally, until an instant-read thermometer registers 150 degrees. 20 to 25 minutes. Transfer pork to a plate, cover with aluminum foil, and let rest 10 minutes (reserve skillet with juices).

  2. To juices in skillet, add mustards, and sour cream, and any accumulated juices from resting pork; whisk over medium heat until heated through (do not boil). Add water, if sauce is too thick.

  3. Slice pork thinly and serve with pan sauce.
