Seriously AMAZING stuffed pork loin with French Onion!
Butterfly the pork. With the pork on a cutting board, hold a knife blade parallel to the board and carefully make a lengthwise cut about 1/3 of the way from the bottom, stopping about 1 inch from the opposite end, being careful not to cut through.
Tightly roll the pork loin to completely enclose all of the fillings.
Using cooking twine, tightly secure the roll.
In the same skillet over medium heat, add the pork loin to the pan and sear on all sides (about 5 minutes on each side). Turning the loin a total of 4 times.
Transfer the skillet to the oven and cook for 25-30 minutes or until the pork loin reaches an internal temperature of 145 °F. Occasionally baste the pork loin with the pan juices.
Increase oven temperature to broil. Top pork loin with remaining cheese and onions and cook for 5 minutes or until cheese is melted and golden brown.
Add parsley for garnish.
