Preheat gas grill to about 350°F using indirect heat. (Direct heat: open flame // Indirect heat: no flame). Turn on about half of the burners. (2-3 burners on a 4 burner grill).

Once preheated, carefully oil the grates or spray them with nonstick cooking spray.

Remove the pork loin from packaging. Sear (with the lid open) over direct heat for 5 minutes per side. Then move the pork to the indirect heat. Close the grill lid.

Cook for 20 minutes, then flip. While cooking, be sure to check for flare-ups and that the temperature stays between 300-400°F. Light another burner or turn on off to regulate temperature.

Cook an additional 10 minutes. Check internal temperature and continue cooking until the thickest part reads 145°F.

Remove from grill and rest for 10 minutes before slicing and serving.

Serve immediately or store in refrigerator for up to 2 days.
