Ingredients

FOR THE POTATOES

FOR THE PORK TENDERLOIN

  • 3 tablespoons olive oil
  • 3 tablespoons honey
  • 4 cloves garlic, minced
  • 1 tablespoon whole grain mustard
  • ½ teaspoon dried rosemary
  • ½ teaspoon dried thyme
  • salt and fresh ground black pepper, to taste
  • 2 pound pork tenderloin

Instructions

  • Preheat oven to 400˚F.
  • Place cut potatoes in a 9x13 baking dish.
  • To the potatoes add 2 tablespoons olive oil, and season with rosemary, salt, and pepper; toss to combine.
  • Bake for 35 minutes.
  • In the meantime, prepare the pork tenderloin.
  • In a mixing bowl combine olive oil, honey, garlic, mustard, rosemary, thyme, salt, and pepper; whisk until thoroughly combined.
  • Brush the pork tenderloin with the honey mixture.
  • Place the pork tenderloin over the potatoes and pour any remaining honey mixture over the potatoes and pork.
  • Bake for 22 to 25 minutes, or until potatoes are tender and tenderloin is cooked through.
    Pork is cooked through when internal temperature registers at 145˚F. Do NOT cook any longer because the pork will be dry.
  • Remove from oven and let stand about 5 minutes before cutting and serving.
