  • 1 3 - 4 pound pork loin roast (get one with a fat cap on it)
  • Salt and freshly ground pepper
  • 2 tablespoons olive oil - divided
  • 2 tablespoons or to taste minced fresh rosemary leaves - divided
  • ¼ cup whole grain mustard
  • 2 large tart sweet apples cored and cut into eights (I used a Honeycrisp and a Granny Smith)
  • 1 large red onion peeled and cut into eights
  • 12 or so fingerling potatoes cut in half across the middle, not lengthwise


  • Salt and pepper the roast generously. Heat an oven-proof skillet over medium-high heat, when hot add half the olive oil and the roast, fat side down, brown well on all sides then remove from the skillet. 
  • While the roast browns, combine the apples, onion, and potatoes in a large bowl, add half the rosemary and the remaining tablespoon olive oil along with a good pinch of salt and pepper. Mix until everything is well coated. Set aside.
  • In a small bowl, combine the remaining rosemary with the mustard. After the roast has browned, spread a thick layer of the mustard mixture on the top (the fat side) and sides of the roast. Mix any leftover mustard mixture into the vegetables. 
  • Heat the oven to 375°F. 
  • Place the vegetable mixture into the skillet, leaving the center open for the roast, nestle the roast in the center, then place in the hot oven and cook for about 1 hour or until the veggies are all soft and the roast is cooked to about 145°F. 
  • Allow the roast to rest for 10 minutes, cut into thin slices and serve with the vegetable mixture. Spoon any accumulated juices over.
