This holiday-worthy roast was inspired by Argentinian matambre arrollado, or beef that is stuffed with hard-cooked eggs, vegetables and sliced cured meats, then poached or roasted. We opted for a boneless pork loin roast because its uniform shape makes it easy to cut into a ½- to ¾-inch-thick slab ideal for filling and rolling. Herbal, garlicky and subtly spicy chimichurri is the perfect accompaniment to the sweet, mild pork; we use some inside the roast, too. You'll need a digital instant thermometer to test the roast for doneness. For convenience, the chimichurri can be made and refrigerated in an airtight container up to a day ahead. The seasonings for the roast can be combined and stored at room temperature and the pork loin can be butterflied and refrigerated a day in advance, too. Additionally, the roast rests for 30 to 60 minutes after cooking, so your oven will be free for last-minute sides.




Don't trim the fat off the pork loin. The fat cap lends richness to an otherwise lean cut and gives the roast an appealing burnished-brown appearance. Don't rush when butterflying the pork loin. Short, small cuts allow for the best control so you can maintain an even slice and adjust as you go. Don't worry if the surface of the butterflied meat is not perfectly flat or even; it won't matter in the finished dish.

This was delicious!!! Amazing! Easy to put together and very impressive. Great recipe here! The chimichurri goes great with this dish! Just make sure to check pork temp after 1hr15min of cooking. I forgot and my pork cooked to 145F instead of 135F but it was still delicious!!!
