Prepare the Meat: remove the tendons from the pork loin but leave the fat on top intact.
3 pounds (1350g) boneless pork loin roast
Cut the Pocket: Using a sharp knife, carefully cut a small slit through the middle of the roast lengthwise without cutting all the way through. This will create a pocket for the prunes.
Season the meat: Generously season the pork with salt and pepper. Combine the spices and rub the meat thoroughly, making sure to coat it all over and inside the pocket.
1 tablespoon marjoram, 2 teaspoons paprika, 1 teaspoon garlic powder, 1 teaspoon thyme, 1 tablespoon table salt, 1/2 teaspoon ground black pepper, 2 tablespoons frying oil
Stuff your roast: Fill the pocket with prunes, don't try to add too many.
3 1/2 ounces (100g) prunes
Marinate Overnight: Place the seasoned and stuffed pork loin in a dish, cover, and refrigerate overnight.
Prepare for Cooking: The next day, take the pork loin out of the fridge one hour before cooking to bring it to room temperature. Preheat the oven to 180°C (350°F).
Sear the Meat: Heat the oil in a large pan over medium-high heat. Briefly pan-fry the pork loin on all sides until browned.
Bake the Roast: Transfer the seared pork loin back to the baking dish and cover it with aluminum foil. Bake for 40 minutes covered, then remove the foil and bake for an additional 20 minutes, or until the internal temperature reaches 145°F (63°C). You can take it out at 142°F (61°C) and it should come to the safe temperature while resting. (Note: Cooking time is roughly 20 minutes per pound.)
Rest and Serve: Let the roast rest for 10–15 minutes before slicing to allow the juices to redistribute. Slice into portions and serve.
Enjoy!
