Prep the Pork. Begin by preheating your oven to 375°F. Pat the pork tenderloin dry with paper towels to remove excess moisture.
Season the Pork. In a small bowl, mix together the salt, black pepper, garlic powder, and paprika. Rub the seasoning mixture evenly over the pork tenderloin, ensuring it's well-coated.
Wrap with Bacon. Carefully wrap the seasoned pork tenderloin with bacon strips, slightly overlapping them to cover the entire surface of the tenderloin.
Roast in the Oven. Transfer the skillet to the preheated oven and roast the pork tenderloin for 25-30 minutes or until it reaches an internal temperature of 145°F, as measured with a meat thermometer.
Sauce. If using, generously brush the raspberry preserves over the top of the bacon wrapped pork tenderloin in the last 10 minutes of baking to give it a chance to caramelize.
Rest and Serve. Remove the pork tenderloin from the oven and let it rest for a few minutes before slicing. Serve hot, garnished with fresh herbs if desired.
