This is so simple and so good. You have to follow the directions exactly though. A friend didn't and hers was way overcooked. It does work.
Preheat oven to 500F.
Lay pork loin on a large sheet of aluminum foil.
Rub pork loin in olive oil. Salt and Pepper to taste. You can add 1/2 pack of Good Seasonings dry Italian mix, if you choose. We like it better with just salt & pepper. Fold foil around the pork loin to hold in the juices.
Cook for 5 min. per pound. So a 3 lb pork loin would cook for 15 minutes. Turn OFF the oven BUT DO NOT OPEN THE OVEN DOOR FOR 2 HOURS. I promise you it will be perfectly cooked every single time.
I prepare this sometimes on Sunday mornings and plan it to turn off the oven as I am walking out the door to church. The pork loin is ready when I get home. LOL!!
