This pork loin recipe is a delicious and easy way to add some Italian flavors to your dinner. The pesto and Parmesan crust adds a rich and savory touch to the pork.

Preheat the oven to 375°F and roast the pork loin for about 45 minutes or until the internal temperature reaches 145°F. Let it rest for 10 minutes before slicing and serving.
