  • 3 tablespoons butter
  • 2 yellow onions, thinly sliced
  • 1/2 cup beef broth
  • 1 (about 3-pound) center-cut pork loin
  • 2 tablespoons extra virgin olive oil
  • 1 teaspoon salt
  • 1/4 teaspoon pepper
  • 1 teaspoon Italian seasoning
  • 2 cups Gruyère cheese, shredded, divided
  • parsley, optional, to taste, chopped, for garnish


Step 1 –Preheat the oven to 450 degrees F.

Step 2 –In a large oven-safe skillet over medium-high heat, melt the butter.

Step 3 –Add the onions and the beef broth to the melted butter and cook until the onions are browned and tender, about 15-20 minutes.

Step 4 –Transfer the cooked onions to a bowl and tent them with foil to keep them warm.

Step 5 –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 pork loin like a book and make a second cut on the thicker side of the pork loin horizontally. Do not cut all the way through and stop about 1 inch from the opposite edge, creating almost a tri-fold. You should now have one, large flat piece of pork.

Step 7 –Cover the entire cut of meat with plastic wrap and pound it to an even 1/3-inch thickness.

Step 8 –In a small bowl, combine the oil, the salt, the pepper, and the Italian seasoning.

Step 9 –Rub the seasoned oil mixture over both sides of the pork loin.

Step 10 –Top the pork loin with 1/2 of the cooked onions and 1/2 of the shredded cheese.

Step 11 –Tightly roll the pork loin to completely enclose all of the filling and tightly secure the roll with cooking twine.

Step 12 –In the same skillet over medium heat, add the pork loin to the pan and sear on all sides, turning the pork a total of four times, about 5 minutes per side.

Step 13 –Transfer the skillet to the oven and cook, while occasionally basting the pork with the pan juices, until the pork loin reaches an internal temperature of 145 degrees F, about 25-30 minutes.

Step 14 –Increase oven temperature to broil.

Step 15 –Top the pork loin with the remaining cheese and the remaining onions and cook until the cheese is melted and golden-brown, about 5 minutes.

Step 16 –Slice the pork loin.

Step 17 –Serve garnished with the parsley.
