Cook’s notes

Back when The Food Network was a new experience for us, we watched a lot of cooking shows, and Curtis Stone’s was among the ones we really liked.
That was a long, long time ago. When the cooking shows turned into reality shows, we gave up on The Food Network. Curtis Stone’s herb-crusted pork, however, remains a family favorite. My husband, Speedy, made this for lunch on a Sunday.
What makes this herb-crusted roast pork so tasty? The combination of the sour mustard and the sweet thyme leaves. And the incomparable flavor of the balsamic vinegar in the dressing. Amazing.

Ingredients

  • 800 grams pork loin (1.76 pounds) with a thin layer of fat one one side (not tenderloin!)
  • 6 tablespoons extra virgin olive oil divided
  • salt
  • pepper
  • 1 tablespoon dried rosemary leaves or twice as much if using fresh
  • 2 to 3 tablespoons prepared mustard
  • 6 sprigs fresh thyme
  • 300 grams baby asparagus (a little over half a pound)
  • 1 teaspoon finely chopped garlic
  • 3 tablespoons balsamic vinegar

Instructions

Roast the pork

  • Preheat the oven to 375F.
  • Rub the pork loin generously with salt and pepper.
  • Heat about two tablespoonfuls of olive oil in a pan, add the pork, fat side down, sprinkle with the rosemary, and cook until lightly browned. Roll the pork in the hot oil for even browning.

  • Transfer the pork to a rack set over a baking dish (to catch drippings).
  • Take the oil in the pan (with the rosemary) and brush all over the browned pork.
  • Roast in a preheated 375F oven for 20 minutes.
  • When the pork is almost done, strip the thyme leaves off the stalks and chop the leaves.
  • Take out the pork out of the oven and place on a cutting board.

  • Spread the mustard evenly all over the hot meat and press the thyme evenly into the mustard.
  • Cover the pork loosely with a foil tent and allow to rest.

Cook the asparagus

  • In a bowl, whisk together the garlic and balsamic vinegar.
  • Pour in the about two to three tablespoons of olive oil in a slow thin stream while whisking continuously.

  • Heat a tablespoonful or so of olive oil in a frying pan and add the baby asparagus in a single layer.
  • Cook, tossing or stirring lightly, to coat each spear with oil (baby asparagus will cook in five minutes or less; larger spears will cook in 10).
  • Drizzle a few tablespoonfuls of the vinaigrette and cook a few seconds longer.

Assemble the dish

  • Transfer the asparagus, with the liquids, on one side of the serving platter.
  • Cut the roast pork into about ¾ inch slices.
