Grilling Pork Loin Roast
Center Boneless Pork Loin Roast
Flavor: 4 Out Of 5
Alternative Names: Center Cut Loin Roast, Double Boneless Loin, Center Cut Pork Roast
The boneless pork loin center roast is part of the pork loin that lies between the sirloin end and rib end on the loin. The loin comes form the area on the pig between the front shoulder and the beginning of the back leg.
Although a center roast with the bone is somewhat more juicier with a little more flavor, the boneless roast is easier to cook and carve.
The center portion of the loin is leaner than the rib end of the loin, which can easily dry out if overcooked. A brined pork roast with a dry rub will cook up juicier with more flavors, so if your pork roast is not enhanced or seasoned we recommend brining the roast before cooking. Read this to learn more about enhanced or seasoned pork. Enhanced or seasoned makes for an easy pork roast.
1. 6-8 hours before grilling pork loin, dissolve ½-¾ cup of kosher salt or 5-6 tablespoons table salt in 3 quarts(2.8 liters) of cold water in a large container. Place pork loin in the saltwater mixture, cover and refrigerate 6-8 hours or overnight. If your roast is enhanced (seasoned) or if you don’t want the roast brined in salt skip step 1.
2. Remove roast from the brine 1 hour before grilling and let the roast stand at room temperature. Rub the roast with olive oil and sprinkle with your favorite dry rub. You can also make several shallow incisions around the surface of the roast and place thin slivers of garlic in each incision.
3. For an added optional smoky flavor soak 2 cups of wood chips in cold water 15-20 minutes. Drain water, place wood chips in a foil tray or metal wood chip box. Place tray over primary burner, replace grate cover and turn all burners to high with lid down for 15-20 minutes
4. Leave primary burner on high and turn off all other burners. Place roast fat side up over the high burner searing 3-4 minutes with the lid down. Turn over and sear the opposite side another 3-4 minutes with the lid down.
5. Move roast to cooler side and grill pork loin with lid down over indirect heat, depending on the size, the pork loin cooking time should be about 30-45 minutes until a instant-read thermometer reads 135-140 degrees into the thickest part of the roast. Try to keep the temperature inside the grill around 375-400 degrees.
6. Transfer grilled pork loin roast to cutting board, tent loosely with foil 15-20 minutes. The internal temperature should rise another 10-15 degrees. Any internal temperature over 150 degrees will begin to dry out the pork roast.
