Season lamb chops with salt and pepper, both sides. Fill smoker with hardwood BBQ pellets. Prepare smoker by placing 2-3 long sheets of aluminum foil along the bottom of the smoker element, underneath the rack, for easy cleanup.
Brush grill rack clean. Set smoker to smoke. Once it starts smoking, set temperature to 225°. Insert meat probe if using. Place lamb chops on grill grates for about 40 minutes or so.
Cook until meat reaches 135° for medium rare, use probe or internal thermometer to check. Remove from smoker, let rest 3 minutes before slicing.
