How to BBQ Rack of Lamb on the Grill

This step-by-step guide will ensure your rack of lamb is perfect.

Trim the Rack

If you didn’t ask the butcher to trim off the excess fat or french the bones, a sharp knife and a cutting board will come in handy here.

Start by removing the fat cap gently with your hands. Use a sharp knife to separate the fat cap from the cut of lamb and shave off any excess fat from the bones.

Frenching the bones refers to removing all the connective tissues, fat, and meat around the bones. While this is not mandatory, it makes for a wonderful presentation.

Allow the Meat to Reach Room Temperature

As with most cuts of meat, rack of lamb cooks better and becomes juicier and more tender when the meat is allowed to come to room temperature before grilling. So let it sit at room temperature for at least 30 minutes prior to cooking. 

Ensure 2-Zone Grilling

For cooking a rack of lamb, it is recommended to prepare two medium-hot fire zones. Light around 100 briquets or a standard chimney of coals, and set them up in two zones. Let the top grate heat up, with all vents open.

Always Oil the Grates

Before setting the rack of lamb on the top grate, use a tightly folded paper towel soaked in oil and use long tongs to rub the towel over the grates to apply a thin coating of oil. This is done to ensure the lamb doesn’t stick.

Foil-wrap the Bones

Protect any exposed bones from catching fire due to flare-ups during the cooking process by wrapping them with foil. The foil will help shield the bones from the high heat required to sear the rack of lamb.

Season the Rack of Lamb

Rub the lamb chops with olive oil and then season with fresh herbs or your favorite rub. Lamb has a mild delicate flavor, so keep things simple. A quick rub of black pepper, kosher salt, and fresh herbs like mint and thyme work well.

Searing the Lamb

Sear the meat on the hotter side of the grill above the coals. Be sure to flip your rack of lamb to ensure a brown color on each side of the meat. Once nicely browned, transfer the rack to the cool side to finish grilling.

Grilling Lamb Over Indirect Heat

Depending on the size of the rack, it should be done cooking in about 15-20 mins total time. However, don’t cook based on time. Make sure to use a reliable meat thermometer to ensure you don’t overcook the meat and pull it from the heat at the target internal temperature.

The rack of lamb reaches medium rare at 125 degrees F, medium at 130 degrees F and well-done at 145 degrees F. If cooked beyond medium, your lamb can acquire a gamey flavor. 

Resting and Serving the Lamb

Once your lamb reaches doneness, remove it from the charcoal grill and allow it to rest, wrapped with aluminum foil, for around 10 to 15 minutes. Resting is important to allow those magical juices to reabsorb/redistributed throughout. 

Using a sharp knife, cut or slice the meat to make small rib chops and serve.
