Generously season the lamb chops with the salt and black pepper.
Let the seasoning absorb by placing the chops in the refrigerator overnight for best results. For a quicker option, let them sit at room temperature for at least 30 minutes.
Fill a charcoal chimney starter with charcoal and light it. Wait until the coals are glowing hot and fully lit, about 15-20 minutes.
Remove the lamb from the refrigerator and pat dry with paper towels to ensure a better crust during searing.
Place an uncoated metal cooling rack directly on top of the lit chimney starter.
Using tongs, sear the lamb loin chops over the open flame. Flip every 30-60 seconds until a deep, even crust forms. This should take about 1-2 minutes per side.
Dump the lit coals onto one side of the grill to create a 2-zone fire (direct and indirect heat).
Add a handful of Post Oak wood chips directly to the hot coals. Close the grill lid, leaving the vents barely open to maintain a low smoking temperature.
Move the seared lamb chops to the cooler side of the grill, away from direct heat.
Close the grill lid and smoke the chops until the internal temperature reaches 130-135℉ for medium-rare, about 15-20 minutes. Use a meat thermometer for precision.
Remove the lamb chops from the grill and let them rest on a cutting board for 5 minutes. This allows the juices to redistribute for maximum flavor.
Serve immediately with your favorite barbecue sides and enjoy!
