how long do you grill a pork roast on a gas grill?
Grill the pork loin for a few minutes on high, or until dark grill marks appear on all sides of the pork. Let it get nice and blackened in a few places, for flavor. Turn the grill down to the lowest heat, or move the pork loin to a spot where will only receive indirect heat. You want the grill to about 300 to 350Â°F. Cover the grill, and let the pork loin cook for about an hour. Check it after 30 minutes, inserting a probe thermometer to check the temperature. When the pork hits 150Â°F*, take it off the grill. Let it rest about 15 minutes, tented with foil.
