1. Preheat the oven to 400 degrees Fahrenheit. The temperature of the oven will eventually be reduced, but you will start it at a higher temperature to give the outside of the pork loin a little extra heat to fully seal in the moisture.
2. Next, go on and season the pork on all sides with the seasonings i.e onion powder, garlic powder, salt, pepper, and olive oil. You can apply them individually or make a tiny dry rub in a small bowl for yourself. Personally, I prefer to mix everything together before putting it on the meat – that way, I know it’s being massaged evenly all over the pork loin.
3. In your roasting pan, proceed to place the pork loin fat side up. By placing the fat on top of the roast, you will be able to baste it as it cooks. This is the process that prevents the pork from drying out and getting tough.
4. Proceed to cook the pork loin for 10 minutes. This will help to form a “crust” on the meat, which will aid to keep the juices inside.
5. Reduce the temperature of your oven to 350 degrees F and cook your roast for another 20 minutes per pound of meat. You will find that it does take some time, but believe me when I say that the wait is well worth it!
6. You can go on and remove the pork loin from the oven once it has reached an internal temperature of 145 degrees F.
7. Then, loosely cover the roasted pork loin with foil and leave it aside to rest for about 10 minutes – another crucial step in keeping the fluids inside the meat where you want them to stay is to do this.

One of the best things about this recipe is how little prep work it requires. Just a quick dry rub and into the oven it goes! So, if you have got some free time but also want to get some work done around the house, this pork loin recipe is for you.
