Mint pesto:

8 cups loosely packed mint leaves

1/4 cup Italian parsley leaves

1/4 cup toasted pine nuts

1/4 cup chopped walnuts

Freshly grated lemon zest from 3 medium lemons (about 2 packed tablespoons)

2 tablespoons fresh lemon juice

3/4 cup olive oil

1 teaspoon sugar

1 teaspoon kosher salt, or to taste

Fresh cracked black pepper, to taste

Instructions

Step 1

Preheat the oven to Roast at 350 degrees F. Rinse and pat dry the leg of lamb. If desired, tie the roast with kitchen string to keep the roast tight and help retain the juices. Coat the lamb with olive oil and then season with salt and pepper. Heat a large skillet over medium heat.

Step 2

Sear the sides of the lamb roast until browned, 3-4 minutes per side. Transfer the roast to a baking dish and place in the oven (or if your skillet is oven safe you can place the skillet directly into the oven). Roast for about 1 hour to 1 hour 20 minutes, or until the internal temperature of the roast is 130 degrees F (rare) or 140 degrees F (medium). (It will increase about 5 degrees more while resting).

Step 3

Remove the roast from the oven, cover with foil, and allow to rest for about 20 minutes. Remove the kitchen string if you tied the roast. Slice and serve the lamb roast with the mint pesto and sautéed green peas.

Step 4

Combine the mint, parsley, pine nuts, walnuts, lemon zest, and lemon juice, in a food processer and pulse until coarsely chopped. Add the olive oil and sugar and process until smooth or to your desired texture. Season with salt and pepper, pulsing to combine. Serve with the roast lamb and sautéed green peas.

Step 5

Heat the oil in a large sauté pan over medium heat. Add the shallots and sauté until soft, 2-3 minutes. Add the peas and cook until heated through, about 1 minute. Season to taste with salt and pepper. Serve warm with the roast lamb and mint pesto.
