Directions
Prepare the Herb Filling
In a mini processor, combine the parsley, rosemary, thyme, green onions, garlic lemon zest and salt. Pulse to ensure all ingredients are evenly incorporated. Stream in the olive oil and blend until fully incorporate.
Prep the Lamb
Lay the boneless leg of lamb flat on a clean surface. Generously rub half of the herb sauce on the inside of the lamb, ensuring it is evenly coated with the aromatic mixture.
Roll and Tie
Carefully roll the lamb into a compact cylinder shape, ensuring the herb sauce remains intact inside. Secure the lamb by tying butcher’s twine around it at regular intervals. This step helps maintain the shape of the lamb during cooking and ensures even cooking.
- Preheat the oven to 400°F convection.
Sear the Lamb
Heat the avocado oil a 14.5” stainless steel roasting pan over medium-high heat. Once hot, place the rolled and tied lamb into the pan, searing it on the fatty side only until very lightly browned. Once seared, remove from the pan, and set aside. Only sear the lamb if there is at least a 1/4-inch (or more) of fat. If the fat has been trimmed more, you will over cook the outside edges of the meat.
- Deglaze the hot pan with ½ cup white wine and scrap the bottom clean before adding the potatoes.
Prep the Potatoes and Onions
In a medium size bowl, toss the fingerling potatoes with 1.5 tablespoon of the olive oil, salt, pepper and paprika. Lay them cut side down on the roasting pan.
- Toss the onion wedges with the remaining ½ tablespoon of olive oil and a sprinkle of salt, then arrange them over the potatoes.
Roast the Lamb
Lay the seared lamb over the potatoes and onions, transfer the roasting pan to a preheated oven. Roast the lamb at 400°F for 15 minutes, the lower the temperature to 315°F convection and cook until the internal temperature reaches 126°F (about 20 minutes per pound). Remove the lamb from the roaster to a cutting board and loosely tent with foil. Rest the lamb for 20 minutes. The internal temperature will continue to rise to about 134°F, a beautiful medium-rare.
- While the lamb is roasting, prepare the mint sauce.
Mint Sauce
Combine the jalapeño, green onions, garlic, vinegar, and salt. Let sit for 10 minutes. Then stir in mint, parsley, and olive oil.
Carve and Serve
Carve the lamb into slices and serve alongside the roasted fingerling potatoes and red onion wedges and your favourite vegetables.
- Note: While the lamb is resting, increase the temperature in the oven to 400°F. Drain excess lamb drippings from the roaster, then finish roasting/browning your potatoes and any other vegetables that you have roasted.
