This elegant roast leg of lamb with grilled summer beans offers a sophisticated update to the traditional Sunday lunch. The lamb is deeply seasoned by studding the meat with garlic and anchovies, which melt during roasting to create a savoury depth of flavour. Served alongside a vibrant mix of charred green and yellow wax beans, the dish feels light yet indulgent, making it a perfect centrepiece for a seasonal dinner party or a family gathering during the warmer months.
As a diabetes-friendly main course, this recipe prioritises high-quality protein and nutrient-dense vegetables over heavy starches. The homemade anchovy-parsley butter provides a rich, creamy finish without the need for a flour-thickened gravy, keeping the dish naturally lower in carbohydrates.

How to make Roast Leg of Lamb with Grilled Summer Beans and Anchovy-Parsley Butter
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 centre of large rimmed baking sheet. Brush lamb with olive oil. Cover with plastic wrap; chill overnight.
Combine parsley, 3 whole anchovies, 3 whole garlic cloves, and lemon peel in processor. Add 90ml 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.
Preheat oven to 232°C. Roast lamb uncovered 30 minutes. Reduce heat to 163°C. Roast lamb until thermometer inserted into thickest part registers 57°C to 60°C, about 1 hour longer. Let lamb rest 30 to 45 minutes.
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.
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.
Transfer lamb to platter. Serve with grilled beans and anchovy-parsley butter.
