Keep your Pork Tenderloins in the bag it's packaged in. It's designed for your oven. Thaw your roast in the refrigerator until completely thawed. Set your oven to 330° F. Place the product in a roasting pan with at least a 2 inch depth. This is to prevent any juices from escaping the bag and making a mess in your oven. This will also make it easier to remove the product from the oven. Bake for about 25-30 minutes at 330° F. Remove from the oven and let cool for at least 10 minutes before cutting open the bag. Open the bag and serve. Use the juices from the bag for a delicious "au jus".
