Roasting lamb on a Kamado Joe is a game-changer. The ceramic cooker’s unparalleled heat retention and insulation create an environment ideal for achieving a beautifully browned exterior and a succulent, tender interior. This guide will walk you through every step, from selecting the right cut of lamb to mastering the Kamado Joe for a truly unforgettable roast.
Choosing Your Lamb Roast
The success of your roast begins with selecting the right cut. Different cuts offer varying levels of flavor, tenderness, and fat content, which will ultimately impact the final result.
Leg of Lamb: The Classic Choice
A leg of lamb is a popular and relatively lean cut, offering a good balance of meat and fat. You can choose between a bone-in or boneless leg. A bone-in leg will generally have more flavor due to the bone marrow, but it can be slightly more challenging to carve. Boneless legs are easier to carve and often come pre-tied, making them convenient.
Shoulder of Lamb: Rich and Flavorful
Lamb shoulder is a tougher cut than the leg, but it’s also incredibly flavorful. It benefits from low and slow cooking, which breaks down the connective tissue and renders the fat, resulting in a meltingly tender and rich roast. Consider a boneless shoulder for easier handling and carving.
Other Cuts to Consider
While leg and shoulder are the most common, other options include a rack of lamb (more suited for grilling or searing) or a loin roast. These cuts are generally smaller and cook faster than the leg or shoulder.
When selecting your lamb, look for meat that is a bright pinkish-red color with firm, white fat. Avoid lamb that appears dull or has discolored fat. The size of the roast will depend on the number of people you are serving. A general rule of thumb is to allow about ½ pound of bone-in lamb per person, or about ⅓ pound of boneless lamb per person.
Preparing the Lamb Roast
Proper preparation is key to a delicious roast. This includes trimming, seasoning, and potentially marinating the lamb.
Trimming and Preparing the Lamb
Start by trimming any excess fat from the lamb roast. While some fat is desirable for flavor and moisture, too much can lead to excessive rendering and a greasy final product. Trim the fat cap to about ¼ inch thick. If you’re using a boneless leg, ensure it’s properly tied with butcher’s twine to maintain its shape during cooking.
Seasoning the Lamb
Lamb benefits from bold flavors. A simple rub of salt, pepper, garlic powder, and rosemary is a classic choice. Other herbs and spices that pair well with lamb include thyme, oregano, mint, cumin, coriander, and paprika.
Consider creating a more elaborate rub by combining dried herbs, spices, and citrus zest. You can also use a wet rub or marinade. A marinade typically includes an acidic component, such as lemon juice, vinegar, or wine, which helps to tenderize the meat.
Apply the rub or marinade generously to all sides of the lamb roast. If using a dry rub, you can apply it just before cooking. If using a marinade, allow the lamb to marinate in the refrigerator for at least 4 hours, or preferably overnight.
Optional: Injecting Flavor
For extra flavor and moisture, consider injecting the lamb with a flavorful broth or marinade. Use a meat injector to distribute the liquid evenly throughout the roast. This is particularly beneficial for leaner cuts like the leg of lamb.
Setting Up Your Kamado Joe
The Kamado Joe is perfect for roasting lamb due to its ability to maintain consistent temperatures for extended periods. Proper setup is crucial for achieving the desired results.
Choosing Your Fuel
Use high-quality lump charcoal for the best flavor and performance. Avoid briquettes, as they can contain additives that can impart an unpleasant taste to your food. Hardwood lump charcoal, such as oak or hickory, is an excellent choice for lamb.
Setting Up for Indirect Cooking
Lamb roasts require indirect cooking to prevent burning the outside before the inside is cooked through. This means using a heat deflector to shield the lamb from direct heat.
The Kamado Joe offers various heat deflector options, such as the Divide & Conquer Flexible Cooking System, which allows you to create different heat zones within the grill. Position the heat deflector(s) to cover the entire firebox, creating a barrier between the charcoal and the lamb.
Maintaining the Right Temperature
The ideal cooking temperature for roasting lamb on a Kamado Joe is around 275-325°F (135-163°C). This temperature allows the lamb to cook slowly and evenly, resulting in a tender and juicy roast. Use the Kamado Joe’s built-in thermometer to monitor the temperature. You can also use a separate digital thermometer for more precise readings. Adjust the top and bottom vents to control the airflow and maintain the desired temperature.
Adding Wood for Smoke (Optional)
For an added layer of flavor, consider adding wood chips or chunks to the charcoal. Fruit woods like apple or cherry pair well with lamb, providing a subtle sweetness. Stronger woods like hickory or mesquite can also be used, but be careful not to over-smoke the lamb. A few small chunks are usually sufficient.
Roasting the Lamb on the Kamado Joe
Now that you’ve prepped the lamb and set up your Kamado Joe, it’s time to get cooking.
Placing the Lamb on the Grill
Place the lamb roast directly on the grill grate, above the heat deflector. Ensure that the lamb is positioned in the center of the grill to promote even cooking. If you are using a bone-in leg of lamb, position it with the bone facing down.
Monitoring the Internal Temperature
The most important factor in determining when your lamb roast is done is the internal temperature. Use a digital meat thermometer to monitor the temperature throughout the cooking process. Insert the probe into the thickest part of the lamb, avoiding any bones.
The desired internal temperature will depend on your preferred level of doneness:
- Rare: 125-130°F (52-54°C)
- Medium-Rare: 130-135°F (54-57°C)
- Medium: 135-140°F (57-60°C)
- Medium-Well: 140-145°F (60-63°C)
- Well-Done: 145-150°F (63-66°C)
Remember that the internal temperature will continue to rise slightly after you remove the lamb from the grill (carryover cooking).
Basting (Optional)
Basting the lamb with pan juices or a flavorful marinade can help to keep it moist and add flavor. Baste the lamb every 30-45 minutes during the cooking process.
How Long to Cook the Lamb
The cooking time will depend on the size and cut of the lamb, as well as the cooking temperature. A general guideline is to allow about 20-25 minutes per pound for a bone-in leg of lamb, and about 15-20 minutes per pound for a boneless leg of lamb. Use the internal temperature as your primary guide, rather than relying solely on cooking time.
Resting and Carving the Lamb
Resting the lamb is crucial for allowing the juices to redistribute throughout the meat, resulting in a more tender and flavorful roast.
Resting the Lamb
Once the lamb reaches your desired internal temperature, remove it from the Kamado Joe and place it on a cutting board. Tent it loosely with foil and let it rest for at least 15-20 minutes. This allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful roast.
Carving the Lamb
Carving the lamb properly will ensure that you get the most tender and flavorful slices.
For a leg of lamb, locate the bone (if bone-in) and slice the meat perpendicular to the bone. For a boneless leg, slice the meat thinly against the grain. For a shoulder of lamb, shred the meat with two forks.
Serving Suggestions
Lamb pairs well with a variety of side dishes and sauces.
Side Dish Ideas
- Roasted vegetables (potatoes, carrots, onions, asparagus)
- Mashed potatoes or sweet potatoes
- Rice pilaf or quinoa

What cut of lamb is best for roasting on a Kamado Joe?
For roasting on a Kamado Joe, a leg of lamb (bone-in or boneless) or a shoulder roast are excellent choices. A leg of lamb provides a good balance of meat and fat, resulting in a flavorful and moist roast. The bone-in option offers more flavor and helps prevent the meat from drying out, while the boneless version is easier to carve.
Alternatively, a shoulder roast is a more economical option. It’s typically fattier than the leg, which renders beautifully during cooking, resulting in a very tender and flavorful outcome. Since it can be a tougher cut, low and slow cooking on the Kamado Joe is ideal to break down the connective tissue and maximize tenderness.
What temperature should I aim for when roasting lamb on a Kamado Joe?
When roasting lamb on a Kamado Joe, a temperature of 275-325°F (135-165°C) is generally recommended. This range allows for slow and even cooking, which helps to render fat, tenderize the meat, and develop a delicious crust on the outside. Maintaining a consistent temperature throughout the cooking process is crucial for achieving optimal results.
For a leg of lamb, aim for the lower end of this temperature range (275°F) for a longer cooking time and more tender result. A shoulder roast, especially, benefits from the lower temperature. If you are using a faster cooking method, such as at 325°F, be sure to monitor the internal temperature closely to prevent overcooking.
How do I prepare the Kamado Joe for roasting lamb?
To prepare your Kamado Joe for roasting lamb, start by filling the firebox with lump charcoal. Use a mix of larger and smaller pieces for consistent burning. Light the charcoal using a natural fire starter. Once the charcoal is lit and burning steadily, install the deflector plates (or heat deflectors) to create indirect heat. This will prevent the lamb from cooking directly over the flames, which can cause it to burn on the outside before it’s cooked through.
Next, place the grill grate on top of the deflector plates. Allow the Kamado Joe to preheat to your target temperature (275-325°F). Ensure your temperature gauge is accurate. Once the desired temperature is reached and stabilized, you’re ready to place the lamb on the grill grate.
What internal temperature should the lamb reach for different levels of doneness?
The desired internal temperature of the lamb depends on your preferred level of doneness. For rare, aim for 125-130°F (52-54°C). Medium-rare is 130-135°F (54-57°C), while medium is 135-140°F (57-60°C). For medium-well, target 140-145°F (60-63°C), and well-done is 145-150°F (63-66°C) or higher.
Remember that the lamb’s internal temperature will continue to rise slightly during the resting period (carryover cooking). It is recommended to remove the lamb from the Kamado Joe when it is 5-10°F below your target temperature to account for this. Use a reliable meat thermometer to accurately monitor the internal temperature during cooking.
How long should I rest the lamb after roasting?
Resting the lamb after roasting is crucial for allowing the juices to redistribute throughout the meat, resulting in a more tender and flavorful final product. Allow the lamb to rest for at least 15-20 minutes, or even longer for larger cuts. This resting period ensures the meat is moist and easier to carve.
To rest the lamb, loosely tent it with foil. This helps to retain some of the heat without steaming the meat. Avoid tightly wrapping the lamb, as this can cause the outer crust to soften. After resting, carve the lamb against the grain for the most tender slices.
What are some good seasonings or rubs for lamb roasted on a Kamado Joe?
Lamb pairs well with a variety of seasonings and rubs. Classic combinations include garlic, rosemary, thyme, salt, pepper, and olive oil. You can also add Dijon mustard or lemon juice for extra flavor. A simple rub of salt, pepper, garlic powder, and dried rosemary is also delicious.
For a more adventurous flavor profile, consider adding spices like cumin, coriander, or paprika to your rub. Harissa paste or a Moroccan-inspired spice blend can also create a unique and flavorful crust. Experiment with different combinations to find your favorite flavor profile. Apply the rub generously to the lamb before roasting.
Can I use wood chips or chunks for smoking lamb on a Kamado Joe?
Yes, you can definitely use wood chips or chunks to add a smoky flavor to your lamb roast on a Kamado Joe. Fruit woods like apple or cherry are excellent choices, as they provide a subtle and sweet smoke that complements the flavor of lamb without overpowering it. Oak or pecan are also good options for a slightly stronger smoky flavor.
To use wood chips, soak them in water for about 30 minutes before adding them to the coals. This helps them to smolder and produce smoke rather than burning quickly. Wood chunks can be added directly to the coals without soaking. Place the wood near the lit coals for optimal smoke production. Monitor the smoke level throughout the cooking process and add more wood as needed to maintain the desired level of smokiness.
