  • 2 pork tenderloins (about 1 lb. each)
  • ¼ cup olive oil
  • 2 tablespoons dry Ranch salad dressing and seasoning mix
  • 1 tablespoon Dijon mustard
  • ½ teaspoon garlic powder
  • ½ teaspoon ground black pepper
  • Optional garnish: chopped fresh herbs, such as parsley, thyme, dill, or chives


  • Preheat oven to 400°F. Line a large baking dish or rimmed baking sheet with foil (for easy cleanup), and spray with nonstick cooking spray.
  • Pat the pork dry with paper towels; place in prepared dish.
  • In a small bowl, whisk together the olive oil, Ranch seasoning, Dijon mustard, garlic powder, and black pepper. Rub the oil mixture all over the pork.
  • Bake for 25-35 minutes, or until the internal temperature of the pork reaches 140-145°F. Allow the pork to rest for at least 5-10 minutes before slicing and serving.


  • Allow the pork to sit on the counter and come to room temperature for about 30 minutes before roasting. This will help the meat cook evenly.
  • For an even crispier exterior, transfer the tenderloin to the broiler for 2-3 more minutes once it's done baking.
  • The total cooking time may vary, depending on the size, thickness, and temperature of your pork when it goes in the oven. As a result, use a meat thermometer to know exactly when your pork reaches the desired level of doneness.
  • Let the pork rest for at least 5-10 minutes before slicing and serving. This will give the juices a chance to redistribute so that your meat is as juicy as possible.
