Pork Tenderloin:

Potatoes (Optional):

  • 5 whole potatoes chopped
  • 2 tablespoons olive oil
  • 1 teaspoon salt
  • 1/2 teaspoon ground black pepper
  • 2 tablespoons fresh parsley chopped or minced


  • Pre-heat the oven to 400°F.
  • If you want to roast potatoes or veggies with your pork tenderloin, now is the time to prep them and get them ready.**
  • Pat the pork tenderloin dry with a paper towel.
  • Rub it down with olive oil.
  • Sprinkle the smoked sea salt and black pepper over the tenderloin, rubbing the seasonings in.
  • Sear the meat in a large skillet (preferably a skillet you can also bake it in), being sure to turn the tenderloin halfway thru searing, so that both sides slightly brown.
  • Place the parboiled potatoes and veggies in the skillet with the tenderloin, sprinkling olive oil, salt, and black pepper over the veggies.
  • Bake everything at 400°F for about 25 to 30 minutes, or until it reaches the recommended internal temperature of 145 to 160°F with a meat thermometer.***
  • Optional step: In the last 5 to 10 minutes of baking, sprinkle parsley over the entire skillet.
  • Once the pork tenderloin is fully cooked, remove it from the oven.
  • Slice the tenderloin and serve with the potatoes and veggies.


*This recipe is based on the size of about a 2 pound pork tenderloin.
**Wash, chop, and parboil potatoes and veggies, so they're ready to go. 
***How long to cook pork tenderloin really depends on a number of factors, including both your oven and the size of your tenderloin.
