Preheat your oven to 400°F (200°C).

Prepare the marinade by mixing olive oil, garlic, rosemary, salt, and black pepper in a bowl.

Rub the marinade all over the pork tenderloin, ensuring it’s well coated.

Heat a large oven-safe skillet over medium-high heat and add the seasoned pork tenderloin.

Sear for about 3-4 minutes on each side until browned.

Pour chicken broth and balsamic vinegar into the skillet around the pork.

Transfer the skillet to the preheated oven and roast for 20-25 minutes, or until the internal temperature reaches 145°F (63°C).

Let the pork rest for 5-10 minutes before slicing.

Slice and serve with the pan juices or your choice of sauce.
