Ingredients
- One 3-4 pound pork loin, butterflied by your butcher or carefully butterflied at home
- 4 tablespoons unsalted butter, divided
- 1 large yellow onion, finely diced
- 3 cloves garlic, minced
- 8 ounces fresh spinach, roughly chopped
- 1 cup fresh breadcrumbs or panko
- 1/2 cup grated Parmesan cheese
- 2 large eggs
- 1/2 cup dried cranberries, roughly chopped
- 1/2 cup walnuts, finely chopped
- 2 teaspoons fresh sage, minced
- 1 teaspoon fresh thyme, minced
- Kosher salt and freshly ground black pepper to taste
- 2 tablespoons olive oil
- 1 cup chicken or vegetable broth
- 1/2 cup dry white wine, optional but recommended
- 2 tablespoons fresh rosemary sprigs for garnish
Instructions
- Preheat your oven to 375°F. If your pork loin hasn’t been butterflied by the butcher, carefully lay it on a cutting board and, using a sharp knife, cut it horizontally through the middle, being careful not to cut all the way through—you want it to open like a book. If the thickness varies, place plastic wrap over it and gently pound it with a meat mallet to create an even 1-inch thickness throughout.
- Pat the butterflied pork loin dry with paper towels and season generously on both sides with kosher salt and freshly ground black pepper. Set aside.
- In a large skillet over medium heat, melt 2 tablespoons of butter. Add the diced onion and cook until softened and translucent, about 4-5 minutes, stirring occasionally.
- Add the minced garlic to the skillet and cook for another minute until fragrant, being careful not to let it brown.
- Add the chopped spinach to the skillet and cook, stirring frequently, until the spinach is completely wilted and any excess moisture has evaporated, about 3-4 minutes.
- Transfer the spinach mixture to a large bowl and let it cool for about 5 minutes.
- To the cooled spinach mixture, add the breadcrumbs, Parmesan cheese, eggs, chopped cranberries, walnuts, sage, and thyme. Mix everything together gently but thoroughly until well combined. Taste and adjust seasoning with additional salt and pepper as needed.
- Lay the butterflied pork loin flat on a clean surface. Spread the filling evenly across the pork, leaving about a 1-inch border on all sides to prevent spillage during cooking.
- Starting from one long side, tightly roll the pork loin, using the filling as you go. The pork should form a tight spiral when viewed from the end.
- Using kitchen twine, tie the rolled pork loin at 2-inch intervals along its length, creating 4-5 ties total. This will help keep the pork together and ensure even cooking.
- In a large oven-safe skillet, heat the olive oil and remaining 2 tablespoons of butter over medium-high heat until the butter is foaming and the oil is shimmering.
- Carefully place the tied pork loin in the hot skillet and sear for 3-4 minutes on the first side without moving it, until a golden-brown crust forms.
- Using tongs, carefully flip the pork loin and sear the other side for another 3-4 minutes until equally golden and caramelized.
- Sear the remaining two sides for about 2 minutes each to create an overall golden crust.
- Remove the skillet from the heat. Pour the white wine (if using) around the pork loin, followed by the chicken broth. The liquid should come about halfway up the sides of the pork.
- Place the skillet in the preheated 375°F oven. Bake for 30-35 minutes, or until the internal temperature reaches 145°F when measured with a meat thermometer inserted into the thickest part of the pork, being careful not to hit the filling.
- Remove the skillet from the oven and transfer the pork loin to a cutting board. Tent it loosely with aluminum foil and let it rest for 5-10 minutes. This resting period is crucial as it allows the juices to redistribute, ensuring moist, tender meat.
- While the pork rests, place the skillet on the stovetop over medium heat. Let the pan juices simmer for 2-3 minutes, stirring to incorporate any browned bits from the bottom. If you’d like a thicker sauce, whisk together 1 tablespoon cornstarch with 2 tablespoons cold water and stir it into the simmering liquid. Cook for another minute until slightly thickened.
- Using a sharp knife, carefully remove the kitchen twine from the pork loin. Slice the pork into 1-inch thick pieces, being careful to keep the spiral intact.
- Arrange the pork slices on a serving platter, drizzle with the pan sauce, and garnish with fresh rosemary sprigs. Serve immediately while still warm.
Pro Tips
Filling variations: Feel free to experiment with different filling combinations based on your preferences. Try substituting the spinach with fresh kale or Swiss chard, or add cooked sausage for extra flavor and richness. You can also use different nuts like pecans or almonds instead of walnuts, or swap the cranberries for dried apricots or cherries for a different flavor profile.
Make-ahead instructions: This pork loin can be assembled up to 8 hours in advance. Simply prepare it through step 10, cover it with plastic wrap, and refrigerate. Remove it from the refrigerator about 30 minutes before cooking to allow it to come closer to room temperature, which ensures more even cooking.
Internal temperature is key: Use a reliable meat thermometer to ensure you don’t overcook the pork. Pork is safe to eat at 145°F, which will still leave it slightly pink in the center—this is perfectly safe and ensures maximum juiciness. Cooking it past 160°F will result in dry, tough meat.
Resting is non-negotiable: Never skip the resting period after cooking. Those 5-10 minutes allow the muscle fibers to relax and reabsorb the juices, resulting in much more tender and moist pork. If you cut into it immediately, all those flavorful juices will run out onto the cutting board instead of staying in the meat.
Serving suggestions: This stuffed pork loin pairs beautifully with roasted root vegetables, creamed spinach, garlic mashed potatoes, or a fresh healthy coleslaw. For a lighter meal, serve it with roasted Brussels sprouts or green beans almondine.
Wine pairing: This dish pairs wonderfully with medium-bodied red wines like Pinot Noir or Grenache, or with fuller-bodied white wines like Chardonnay. The cranberries and walnuts in the filling provide a nice bridge to these wine styles.
Leftover storage: Sliced leftover pork loin can be refrigerated in an airtight container for up to 3 days. Reheat gently in a 350°F oven, covered with foil, for about 10-15 minutes to avoid drying it out. You can also use the leftovers in sandwiches or salads.
