Step 1: Cut Down the Center
Place the pork loin fat side down on a large cutting board (Freshware Bamboo Cutting Board, Walmart). Use a long, sharp knife to cut lengthwise down the center of the meat. Don’t cut all the way through—it’s critical to leave about ½ inch uncut along the bottom to hold both sides of the loin together.
Step 2: Butterfly the Left Side
Place your knife at the base of the V you just created, so that the blade is perpendicular to your first cut. Using shallow slices and the cutting board as a guide, cut through the left side of the loin. Maintain a ½- to ¾-inch thickness and unroll the meat as you cut.
Step 3: Finish Butterflying and Pound Even
Repeat the same cut on the right side of the loin, making shallow slices and unrolling the meat. You should end up with a flat, relatively even thickness across the entire piece of meat. If some areas of the pork are thicker than others, put a layer of plastic wrap on top of the meat and pound the thick spots with the flat side of a meat mallet. (We prefer the KitchenAid Aluminum Meat Pounder, Target.) Now comes the fun part—once you’ve butterflied the pork loin, the tricky part is over and you can focus on creating your filling. Typically, pork loin stuffing includes a touch of sweetness from fruit, like cherries, apricots, or dried fruit pieces, and savory components, like vegetables, wild rice, onions, or mushrooms. Fresh herbs are a popular ingredient to add to stuffing. Or create an herb-based stuffing like the one in our parsley- and cilantro-filled chimichurri pork loin recipe. Whatever filling you choose, season your meat lightly with salt and pepper, then spoon in the filling. Starting on a short side, roll your pork into a spiral, and secure it with 100%-cotton kitchen string. Then follow the recipe instructions for roasting. Special-occasion dinners should be a breeze for you now.
