The Cut: What is a Pork Loin Roast?

A pork loin roast, also known as a pork loin, is a long roast cut from the back upper portion of the pork behind the shoulder. It’s the same area where pork chops are carved from and often found in most grocery stores’ fresh meat department. Most of the time, they are boneless, making them an affordable large roast, especially if you’re feeding a large family. But if you’re lucky enough to find a bone-in roast, you can make an oven-roasted rack of pork.

Often, it’s easy to confuse pork loin and tenderloin due to how they are packaged, but they are different cuts of meat. Pork loin roasts are bigger and will have a thin layer of fat on top. This lean cut of pork ranges from 3 to 7 pounds at the market and is great for grilling, smoking, baking, or even easy slow cooker pulled pork. You can even buy the larger loin roasts and trim them into individual smaller roasts or boneless pork chops for later.

When buying a pork loin, look for an even fat cap from end to end for the best results.

Ingredients

  • Boneless pork loin roast – the one we show in this recipe is a beautiful roast with a thick fat cap from Porter Road Butchers, one of our favorite places to order meat online. We love the thick fat layer that Porter Road keeps on the pork compared to what we find at our local grocery store.
  • Kosher salt
  • Fresh head of garlic
  • Oil – avocado oil or your favorite neutral cooking oil
  • Fresh rosemary sprigs
  • Onion
  • Carrots
  • Lemon

How to cook a pork loin Roast

We keep this roast simple, with veggies and rosemary, but feel free to add your favorite spice rub if you want to mix up the flavors. Try Italian seasoning or barbecue spices to amp up the flavor of the pork, depending on what side dishes you want to serve with it.

Prep the pork

  • Start by removing the pork from the package and patting it dry with paper towels. If the fat cap is over 1/4″ thick, consider trimming it with a sharp filet knife if your family doesn’t love the fat layer. Then liberally season the roast with salt and let it dry brine in the fridge overnight. When ready to cook, let the pork loin roast sit at room temperature for 30 minutes while you preheat the oven to 325 degrees F.
  • Next, preheat a well-seasoned cast iron skillet, braiser, or large Dutch oven over medium-high heat until it just starts to smoke. Place the pork, fat side down, in the hot skillet to sear the fat cap for about 7 to 9 minutes until it’s golden brown. Transfer the pork to a cutting board using long tongs and remove the pan from the heat.
  • Carefully cut off the top 1/4 portion of the head of garlic to expose the bulbs, then drizzle it with oil. Add the head of garlic to the cast iron skillet along with the chopped onion, carrot, and lemon wedges. Place the rosemary springs on top of the veggies and nestle the pork loin, fat side up, on top of it all.

ROAST THE PORK

  • Carefully transfer the skillet to the hot oven and roast the pork for about 45 minutes to 1 hour, or until the internal temperature reaches 140 degrees F with an instant read thermometer. The trick to juicy pork is not overcooking it, so keeping an eye on the internal temperature is important.
  • Remove the skillet from the oven and transfer the pork roast to a clean cutting board. Top it with a dollop of herb compound butter and tent the entire roast loosely with foil to rest for 10 minutes. As the pork rests, the internal temperature of the roast will continue to rise to 145° F.

SERVE

  • After it has rested, slice it into 1/2″ thick juicy pork loin portions with a sharp knife. Sprinkle it with freshly minced parsley and a pinch of salt and black pepper. Serve the pork over the roasted veggies, squeezing the roasted garlic cloves out and using it on a toasted baguette or mixing it into the veggies.

Girl Carnivore Expert Recipe Tips

  • According to the USDA, pork is safe to eat at 145 degrees F, which means it will be juicy and may have a slightly pink center. An accurate digital meat thermometer is the only way to guarantee a perfectly cooked pork roast.
  • We use clean cast iron to keep this a one-pan meal (fewer dishes), but you could sear it in a skillet and transfer the pork to a roasting pan if you don’t have oven-safe cast iron.
  • We tie our roast every 2 to 3 inches with butcher’s twine to help it maintain an even shape for more consistent cooking. You can ask your butcher to do this for you.
  • Add fennel, parsnips, potatoes, or turnips to the vegetable mix to beef up the vegetables. Use what you have on hand.
  • We love to serve this roast pork loin recipe with a mustard cream sauce made with the pan drippings.

What to Serve With

Because you roast this over veggies, you have a built-in side dish to pair this delicious recipe with. However, it’s also great with roasted green beans, foil wrapped baked potatoes, mashed potatoes, or Brussels sprouts au gratin.

Wine Pairing

Pork is mild, so pair it with a wine that doesn’t overpower it. Stick with a dry Sauvignon Blanc if you like white wine or a light Pinot Noir if you prefer red wine.

Leftovers and Reheating

Wrap any leftover pork roast tightly in aluminum foil after it’s cooled. Store it in the fridge for up to 4 days. To reheat, slice off what you need from the whole roast. Then reheat the individual portions wrapped in foil in an oven preheated to 325 degrees F.
