  • 24 ounces pork tenderloin
  • 1 tablespoon olive oil
  • 2 teaspoons garlic powder
  • 1 teaspoon salt
  • 1 teaspoon ground black pepper
  • 1 tablespoon dried parsley
  • 1 teaspoon onion powder
  • 3 tablespoons salted butter, cut into 1 tablespoon squares
  • ¼ cup fresh parsley, finely chopped


  • Preheat the oven to 400°F and line a baking sheet with aluminum foil. Set it aside.
  • In a medium bowl, combine garlic powder, salt, pepper, dried parsley, and onion powder. Whisk to combine.
  • Pat pork tenderloin dry with paper towels. Sprinkle seasoning mixture on all sides, and on the ends of the pork. Rub into the pork with your fingers to evenly distribute seasonings.
  • In a large skillet over medium heat, add olive oil. Once olive oil is hot and shimmering, add the pork tenderloin and sear the pork until browned on all sides. Once browned on all sides and ends, remove from the skillet and place on the aluminum foil.
  • Place 3 squares of butter evenly spaced on top of the pork tenderloin and wrap aluminum foil tightly around the sides, top, and edges.
  • Place in the oven and let roast for 20 to 30 minutes, or until the internal temperature reaches between 145 to 160°F in the middle of the tenderloin when tested with a meat thermometer.
  • When the pork tenderloin reaches the desired temperature, remove it from the oven, sprinkle fresh parsley over the top, and tent with aluminum foil.
  • Allow meat to rest for 5 minutes before slicing against the grain to serve.


  • Oven temperatures vary and may need to be recalibrated periodically to ensure they are accurate. Make sure to keep a close eye on your pork as the suggested baking time approaches.
  • Use the following temperature guide to cook your pork: 
    • Medium-rare between 145 to 150°F
    • Medium between 150 to 155°F 
    • Medium-well 155 to 160°F
    • Well done at or above 160°F
