How to Roast a Succulent Bone-In Pork Loin

Pork loin roast is a delicious and versatile cut of meat that can be the centerpiece of a special dinner when cooked properly. Roasting a bone-in pork loin may seem intimidating, but it’s actually quite simple with a few tips. In this comprehensive guide, we’ll walk through everything you need to know to roast bone-in pork loin to juicy, tender perfection.

Selecting the Right Cut

The key to a great roasted pork loin is starting with the right cut. Look for a center cut bone-in pork loin roast, ideally around 3 to 4 pounds. The bone helps keep the meat moist and adds extra flavor as it roasts. Avoid cuts with too much fat around the outside, which can make the pork greasy. When ready to cook, trim off any excess fat so the seasoning adheres directly to the meat.

Proper Seasoning

One of the secrets to incredible roast pork loin is getting the seasoning right. Start by patting the meat dry, then rub it all over with olive oil. This helps the seasoning stick to the meat. Next sprinkle generously with salt pepper and dried herbs like rosemary, thyme and sage. Garlic powder, onion powder and paprika also make excellent additions. Rub the seasoning all over the pork, covering all sides. Let it marinate for at least an hour, or up to overnight. The longer the better for the flavor to permeate the meat.

Low and Slow Roasting

The ideal oven temperature for roasting bone-in pork loin is around 325-350°F Any hotter and the outside risks overcooking before the inside is done. Place the seasoned pork in a roasting pan and cook for around 1 hour 15 minutes for a 3-4 pound roast Halfway through, add diced potatoes or other veggies like carrots to the pan to roast in the juices.

An instant-read thermometer is crucial for perfect pork. Remove it from the oven when it reaches 140°F, then let rest for 10 minutes until it reaches the food safe 145°F. If it’s not quite there yet, pop it back in for a few more minutes. Roasting low and slow results in incredibly tender and moist pork.

Carving and Serving

Once rested, use a sharp knife to carefully slice the pork loin roast. You can carve it off the bone in one piece, or slice between each rib bone to serve as individual chops. Arrange the carved pork on a platter with the roasted veggies and drizzle with a bit of the pan juices.

Serve it with rice, potatoes or pasta to soak up the delicious meat juices Pork pairs wonderfully with fruit, so try it with a cranberry sauce or an apple compote Leftovers make amazing sandwiches or can be used in stir fries and pasta dishes.
