Roast Leg of Lamb with Grilled Summer Beans and Anchovy-Parsley Butter

Preparation

1. Step 1

   Using small sharp knife, make sixteen 1-inch-deep slits all over lamb. Push 1/2 anchovy and 1 garlic quarter into each slit. Place lamb on small rack in center of large rimmed baking sheet. Brush lamb with olive oil. Cover with plastic wrap; chill overnight.

   Step 2

   Combine parsley, 3 whole anchovies, 3 whole garlic cloves, and lemon peel in processor. Add 6 tablespoons olive oil; blend to coarse paste. Add butter; blend until smooth. Season butter with coarse salt and freshly ground pepper. Transfer anchovy-parsley butter to small bowl. DO AHEAD: Can be made 1 day ahead. Cover; chill. Bring to room temperature before using.

   Step 3

   Preheat oven to 450°F. Roast lamb uncovered 30 minutes. Reduce heat to 325°F. Roast lamb until thermometer inserted into thickest part registers 135°F to 140°F, about 1 hour longer. Let lamb rest 30 to 45 minutes.

   Step 4

   Meanwhile, prepare barbecue (medium-high heat). Combine beans and 3 tablespoons oil in large bowl; sprinkle with coarse salt and pepper and toss to coat.

   Step 5

   Place grill basket on barbecue. Spread out beans in basket (reserve bowl). Grill beans until slightly charred, tossing often, 15 to 18 minutes. Return beans to reserved bowl. Toss with 1 1/2 tablespoons oil and 1 1/2 tablespoons lemon juice. Season with coarse salt and pepper.
