The sizzle on the charcoal, the incredible aroma of fresh rosemary and thyme, and that first juicy, tender bite—it’s a culinary masterpiece that’s surprisingly simple to achieve. This recipe harnesses the power of two-zone grilling to create a beautifully seared crust and a succulent, pink interior. Let’s fire up the grill and create something truly unforgettable.
Ingredients
• 2 grass-fed racks of lamb, approx. 2.5 lbs / 1.1 kg (2.43 lb) each
• 2 tablespoons Dijon mustard
• 2 teaspoons (10 ml / 0.3 fl oz) fresh rosemary, finely chopped
• 2 teaspoons (10 ml / 0.3 fl oz) fresh parsley, finely chopped
• 2 teaspoons (10 ml / 0.3 fl oz) fresh thyme, leaves stripped
• Salt and freshly ground black pepper, to taste
Instructions
1. Directions
2. Prepare the Grill: Preheat your charcoal grill for high heat. Once the coals are hot and ashed over, bank them to one side to create a two-zone fire: a hot direct heat zone and a cooler indirect heat zone. Clean and grease the grill grates to prevent sticking.
3. Season the Lamb: Pat the racks of lamb dry with a paper towel. Season generously on all sides with salt and freshly ground black pepper.
4. Create the Herb Crust: Spread the Dijon mustard evenly over the meaty, fat-capped side of each rack. Firmly press the mixture of fresh rosemary, parsley, and thyme onto the mustard to create an even crust.
5. Sear Over Direct Heat: Carefully place the lamb racks, herb-side down, directly over the hot coals. Sear for 4-6 minutes, watching closely to develop a deep brown crust without burning the herbs.
6. Flip and Sear: Flip the racks and sear the bone-side for another 2-3 minutes over direct heat.
7. Move to Indirect Heat: Move the racks to the cooler, indirect heat side of the grill, meaty side up.
8. Cook to Perfection: Cover the grill and cook for 15-20 minutes, or until an instant-read thermometer inserted into the thickest part reads 135°F / 57°C for a perfect medium-rare.
9. Rest and Serve: Remove the lamb from the grill and transfer to a cutting board. Tent loosely with foil and let it rest for at least 10 minutes. This is crucial for juicy, tender meat. Slice into chops and serve immediately.

Pro Tips
• Use an instant-read meat thermometer for perfect results. Pull the lamb off the grill about 5 degrees below your target temperature, as it will continue to cook while it rests.
• Ask your butcher to ‘french’ the racks for you. This means they’ll trim the fat and meat from the ends of the bones for a stunning, professional presentation.
• Don’t skip the rest! Tenting the lamb loosely with foil while it rests for 10-15 minutes allows the juices to redistribute, ensuring every bite is succulent.
FAQ
Q: What is two-zone grilling and why is it important for lamb
A: Two-zone grilling creates a hot side for direct heat and a cooler side for indirect heat. This method is perfect for lamb because it allows you to get a beautiful, deep brown sear on the crust over direct heat, then move it to the cooler side to cook gently to the perfect internal temperature without burning the outside.
Q: What internal temperature is best for medium-rare rack of lamb
A: For a perfect medium-rare, cook the rack of lamb until an instant-read thermometer inserted into the thickest part reads 135°F (57°C). Remember to pull it from the grill about 5 degrees early, as the temperature will continue to rise while it rests.
Q: Can I make this recipe on a gas grill
A: Yes, you can adapt this recipe for a gas grill. To create a two-zone setup, turn the burners on one side of the grill to high and leave the burners on the other side off or on low. Sear the lamb over the high-heat side, then move it to the cooler side to finish cooking with the lid closed.
Q: Why is it important to rest the lamb after grilling
A: Resting the lamb for at least 10 minutes is a crucial step. It allows the muscle fibers to relax and the juices to redistribute throughout the meat. If you slice it too soon, the juices will run out onto the cutting board, resulting in a less tender and flavorful final product.
Pro Tips
- Build a two-zone fire: once the coals are hot and ashed over, bank them to one side so you have a hot direct zone and a cooler indirect zone.
- Sear the racks herb-side down over direct heat for 4-6 minutes, watching closely so the herbs brown rather than burn, then sear the bone side 2-3 minutes more.
- Move the racks meaty-side up to the indirect zone, cover the grill, and cook 15-20 minutes to 135°F / 57°C for medium-rare.
- Pull the lamb about 5 degrees below your target temperature — it keeps cooking as it rests.
- Ask your butcher to 'french' the racks (trim the fat and meat from the bone ends) for a stunning, professional presentation.
Frequently Asked Questions
What is two-zone grilling?
It means banking the coals to one side so the grill has a hot direct-heat zone for searing and a cooler indirect zone for gentle roasting. The racks get the best of both: crust outside, even pink interior.
Is herb-crusted rack of lamb keto-friendly?
Yes — each of the six servings has about 1g of carbohydrates with 45g of protein and 21g of fat. The crust is Dijon mustard and fresh herbs.
What internal temperature should the lamb reach?
135°F / 57°C in the thickest part gives you medium-rare. Pull the racks about 5 degrees early since they continue to cook off the grill.
How long should the lamb rest?
At least 10 minutes (10-15 is ideal), tented loosely with foil. This is the step that guarantees juicy, succulent chops instead of losing the juices on the board.
