Set the oven at 350°f (175 degrees Celsius).

Pat the pork tenderloin dry using paper towels to remove any excess moisture.

In a small bowl, mix together the olive oil, dried herbs, salt, pepper, and minced garlic to make a seasoning mixture.

Rub the seasoning mixture all over the pork tenderloin, making sure to coat it evenly.

Heat a large oven-safe skillet or a roasting pan over medium-high heat. Once the pan is hot, place the pork tenderloin and sear it on all sides until browned. This step helps to lock in the flavors and juices.

Transfer the skillet or roasting pan with the pork tenderloin into the preheated oven.

Roast the pork tenderloin for about 20 to 25 minutes, or until it reaches an internal temperature of 145 degrees F.(63 degrees Celsius). It's essential to use a meat thermometer to accurately check the temperature.

Once the pork tenderloin reaches the desired temperature, remove the pork in the oven and tent it loosely with aluminum foil. Let the pork rest for at least 5 to 10 minutes. This allows the juices to redistribute throughout the meat, resulting in juicy and tender pork.

After resting, slice the pork tenderloin into thin medallions and serve it warm.
