Step 2

Step 5

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.

Step 6

Open the loin like a book.

Step 7

Make a second cut on the thick side of the pork loin, horizontal with the first cut. Do not cut all the way through, stop about 1 inch from the opposite edge. Fold that edge over making one long cut of pork loin.

Step 8

Cover the entire cut of meat with plastic wrap and pound to an even 1/3 inch thickness.

In a small bowl, combine oil, salt, pepper, and Italian seasoning. Rub over both sides of pork loin.

Step 12

Using cooking twine, tightly secure the roll.

Step 13

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.

Step 14

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.
