Preheat the oven to 375 degrees F.
Next, lightly grease a baking dish with some olive oil.
Add the pork loin to a large bowl, pierce with a small knife 9 holes on top, or make as many based on how many cloves you will use. Fill those holes with 9 whole garlic cloves.
Then, add the rest of the ingredients to the pork and rub it well on all sides.
Add the pork loin to the prepared baking pan, fat side up.
Cook for 50-55 minutes for medium to medium-well doneness (150-155 degrees F for internal temperature). Cook for 60-70 minutes for a well to be well-done, or until it has reached a temperature of 160-165 degrees F.
Remove from the oven and let it rest for 5-10 minutes before slicing and serving.
