Ingredients: 1.5 kg Butter (butterflied); 1 Mint (finely chopped); 4 clove Garlic (minced); 100 ml Olive Oil (good quality); Zest and Juice of 1 Lemon; 2 tsp Salt (Maldon)); 1 tsp Black Pepper; Cherry (soaked)

Grilled Lamb Shoulder with Mint and Garlic | Smoke & Soil

Lamb shoulder is a cut that improves with time and low heat. Three hours in and the fat has rendered, the collagen has broken down, and the whole thing is ready to pull apart rather than slice. This slow transformation delivers tender, juicy meat that carries the subtle complexity of smoke and fire without losing the clean, natural flavours of the lamb.

This recipe leans into that process, combining indirect heat cooking on the BBQ with a marinade built around fresh mint, garlic, and lemon. The acidity from the lemon juice gently tenderises the meat while the mint and garlic add brightness and depth without overpowering. Butter and olive oil help keep the shoulder moist during the long cook, ensuring the final result is rich but balanced.

The technique calls for a two-zone setup on the grill, allowing you to start with direct heat to develop a crust before moving to indirect heat to cook the shoulder through evenly. Using an instant-read thermometer here is key to hitting the right internal temperature without guesswork. It’s a recipe that rewards patience and attention, showcasing how everyday BBQ can be both approachable and refined, with clean, whole-food ingredients at its heart.

Health Notes

British grass-fed lamb is a good source of complete protein and a useful dietary source of iron and zinc. Shoulder and shanks have more fat than leg or loin — trim visible fat before cooking if you prefer a lighter result.

Notes

Timing Clarification: The cook time is an estimate for a 1.5kg boneless shoulder. A bone-in shoulder will require significantly longer, potentially 3-4 hours, and a lower temperature (135°C / 275°F) to break down the connective tissue. Always use the internal temperature as your primary metric.
Alternative Herbs: If fresh mint is unavailable or not preferred, a combination of fresh rosemary and oregano works equally well with lamb. The principle of using robust, fresh herbs remains the same.
Why Resting Works: The resting period is crucial. Immediately slicing the lamb will cause the internal juices to run out, resulting in a dry joint. Resting allows the temperature gradient to even out and the moisture to be reabsorbed, leading to a far superior texture.

Seasonal Variations

Swap shoulder for bone-in leg in spring for a leaner result

Method

1
Prepare the Lamb and Marinade
Pat the lamb shoulder dry with paper towels. In the mixing bowl, combine the chopped mint, minced garlic, olive oil, lemon zest, lemon juice, salt, and pepper. Rub the mixture thoroughly over all surfaces of the lamb. Place the lamb in a sealed container or bag and refrigerate for a minimum of 2 hours, or ideally overnight.
2
Set Up the Grill for Indirect Heat
Arrange the Weber Master-Touch for a two-zone fire. Light a chimney starter full of Weber briquettes. Once fully lit and ashed over, pour the briquettes onto one side of the charcoal grate. Place the cooking grate on top. Close the lid and adjust the bottom and top vents to achieve a stable dome temperature of 150°C (300°F). If using, place the soaked wood chips directly onto the hot briquettes just before placing the lamb on the grill.
3
The Cook
Place the lamb shoulder on the cooking grate, directly over the side with no coals (the indirect heat zone). Insert the meat thermometer into the thickest part of the joint, ensuring it does not touch bone or the grate. Close the lid. Cook for 90 to 120 minutes, rotating the lamb halfway through to ensure even cooking. Maintain the 150°C (300°F) temperature by adjusting the vents as necessary.

Monitor and Finish
The lamb is ready when the internal temperature reaches your desired doneness: 60°C (140°F) for medium-rare, or 70°C (158°F) for medium. Do not rely on time alone. Once the target temperature is reached, remove the lamb from the grill.
60°C
5
Rest and Serve
Wrap the cooked lamb tightly in aluminium foil or butcher paper and allow it to rest on a cutting board for a minimum of 15 minutes. This is a non-negotiable step that allows the muscle fibres to relax and redistribute the internal juices, ensuring a tender and moist result. Slice the lamb against the grain and serve immediately.
