Pork Tenderloin with Apples and Onions
  1. 1

    Preheat the oven to 425 degrees F (220 degrees C).

  2. 2

    Trim the silver skin from the pork tenderloins; pat dry with paper towels. Rub 2 teaspoons vegetable oil over the tenderloins, then rub with sea salt.

  3. 3

    Heat 1 tablespoon vegetable oil in a large, oven-proof skillet over medium heat until it shimmers. Cook the tenderloins in the hot oil, turning to brown all sides, about 10 minutes. Transfer the pork to a large plate.

  4. 4

    Add the remaining 1 tablespoon vegetable oil to the drippings in the skillet. Cook the apples and onions in the hot oil, stirring occasionally, until the onions are translucent, about 5 minutes; add more oil if the skillet becomes dry. Season with 1 teaspoon thyme and black pepper; stir gently to combine. Remove from the heat.

  5. 5

    Use a pastry brush to spread Dijon mustard evenly over the tenderloins. Sprinkle with the remaining 2 teaspoons thyme. Nestle the tenderloins into the skillet with the apple mixture.

  6. 6

    Roast, uncovered, in the preheated oven until an instant-read thermometer inserted into the center of the tenderloins registers at least 145 degrees F (63 degrees C), about 15 minutes. Remove the skillet from the oven and transfer the pork to a large platter. Cover with aluminum foil and let rest.

  7. 7

    Meanwhile, pour the chicken stock into a saucepan and cook over medium-high heat until reduced by half, 8 to 10 minutes. Pour it into the skillet with the apple mixture. Cook over medium-high heat until boiling, about 5 minutes; stir in the butter until melted.

  8. 8

    Slice the pork and serve over the apple mixture.
