Butterflied and stuffed, this delicious Grilled Pork Roast with Rosemary and Garlic makes a wonderful roast for a weeknight meal or dinner party.
Did I mention that I love summer?! Since the days are longer, I’m finding every excuse to grill outside. The kids get to play, mom and dad get to relax and the whole family can enjoy a delicious meal.
One of my favorite cuts of meat is the pork loin. It is larger than the pork tenderloin cut, but just as tender, moist and delicious. It is also a cheaper cut of meat compared to the tenderloin, which makes it perfect for my wallet and for feeding my family of five.
Best cut of meat for grilled pork roast
Since I like to use the pork loin, I usually purchase the large 8-pound pork loin from Costco then cut it in thirds. If I am not using the meat right away, I then vacuum seal each roast and freeze them individually. For this recipe, I am using one of the roasts which is now about 2 1/2 pounds in size.
How to butterfly a pork loin roast
To butterfly this pork loin, place roast fat-side up on cutting board. Starting about 1-inch up from cutting board, cut horizontally, stopping about 1/2 inch before the edge. Now, cut into thicker half of roast, again, starting about 1 inch from cutting board and stopping about 1/2 inch before edge.
You are basically slicing your roast but not all the way and pulling up and opening the roast like a page of a book. It sounds more complicated than it is, trust me. Once your pork roast is open and one flat piece of meat, approximately 1/4-1/2 inch thick, you can layer in the garlic and rosemary stuffing.
The stuffing for grilled pork roast
You can use almost any kind of stuffing for your pork loin roast. Now you can see why I love preparing this dish? The flavor options are limitless: chimichurri, pesto, cranberry sauce, marinara. I have a fabulous recipe for an Italian Pork Roast where I layer in proscuitto and basil pesto.
For this grilled pork roast, I minced rosemary, parsley, garlic and olive oil and spread it inside. Oh the smell of fresh herbs and garlic! Once everything is spread over your pork roast, roll it up and tie it kitchen twine. When your roast is cooked and you cut into it, you will find this beautiful herbal swirl inside the roast!
Tips on grilling your pork roast
The key to moist and juicy pork, especially on the grill, is to sear the meat to seal in the juices. Because you are grilling a 2 1/2 pound roast, you want your roast to be browned and caramelized on the outside, but moist and cooked thoroughly on the inside.
The trick is to heat up your grill on high for 10-15 minutes. Then brown the roast with all the burners on, or if you are using a charcoal grill, place the roast directly on the coals. It takes about 12 minutes to brown all sides of the roast
After the roast is browned, you reduce the heat on the grill and cook the roast slowly until the internal temperature is 140º, about 35 minutes. Just like all meats, you should let it rest for 10 minutes, keeping it tented as the temperature inside reaches a safe 145ºF.
It might sound complicated, but it’s not. And when you bite into the swirls of herbs and the pork, you will savor every bite. As my son, The Professor, proclaimed: “Mom, the plant stuff inside tastes good!”
