Preheat your oven to 400 degrees Fahrenheit with the rack positioned in the middle.
Rub the prepared pork tenderloins with olive oil to help the seasonings adhere.
In a small bowl, combine brown sugar, smoked paprika, garlic powder, onion powder, chili powder, Italian seasoning, salt, and black pepper. Stir until evenly distributed.
Coat all sides of the pork tenderloins generously with the seasoning mixture.
Place the seasoned pork tenderloins in a baking dish and dot the top with butter.
Bake uncovered for approximately 25 minutes, until the internal temperature reaches 145 degrees Fahrenheit.
Once cooked, remove from the oven and let it rest for 5 to 10 minutes before slicing into half-inch thick medallions.

Using a meat thermometer is essential to ensure perfect doneness.

Consider brining the pork tenderloin in saltwater for improved moisture retention.

Leftover pork tenderloin can be stored in an airtight container in the refrigerator for up to three days or frozen for up to three months.
