Za'atar Roast Chicken with Green Tahini Sauce

This aromatic za'atar roast chicken is a vibrant celebration of Middle Eastern flavours, bringing together earthy spices and zesty citrus. The chicken is marinated in a blend of sumac, cinnamon, and allspice, ensuring every bite is deeply savoury and succulent. Roasted alongside red onions and lemon slices, the meat develops a beautiful crust while the onions caramelise into a sweet, jammy accompaniment. It is a fantastic option for those seeking a high-protein meal that does not compromise on excitement or complexity.

To finish the dish, a bright green tahini sauce provides a creamy, herbal contrast to the spiced poultry, while buttery toasted pine nuts add a delicate crunch. This recipe is perfect for a weekend lunch or a nutritious midweek feast when prepared in advance. Serve it family-style in the centre of the table with warm flatbreads to soak up the aromatic roasting juices.

  • 120ml tahini

  • 60ml fresh lemon juice

  • Kosher salt

  • 1 3 1/2–1.8kg chicken, cut into quarters, or 2 large skin-on, bone-in chicken breasts and 2 skin-on, bone-in chicken legs

  • 2 medium red onions, thinly sliced

  • 2 garlic cloves, smashed

  • 1 lemon, thinly sliced, seeds removed

  • 1 tablespoon sumac

  • 1 1/2 teaspoons ground allspice

  • 1 teaspoon ground cinnamon

  • 240ml low-sodium chicken broth or water

  • 60ml olive oil, plus more for drizzling

  • Kosher salt, freshly ground pepper

  • 2 tablespoons za'atar

  • 2 tablespoons unsalted butter

  • 60g pine nuts

  • 6 pieces lavash or other flatbread

  • Za'atar and sumac are available at Middle Eastern markets and specialty foods stores, and online.

Green tahini sauce Pulse garlic, parsley, tahini, lemon juice, and 120ml water in a food processor, adding more water if needed, until smooth (sauce should be the consistency of a thin mayonnaise); season with salt.

Do ahead: Sauce can be made 1 day ahead. Cover and chill.

Chicken and assembly Preheat oven to 400°. Toss chicken, onions, garlic, lemon, sumac, allspice, cinnamon, broth, and 60ml oil in a large resealable plastic bag; season with salt and pepper. Chill at least 2 hours.

Place chicken, onions, garlic, and lemon on a rimmed baking sheet, spooning any remaining marinade over and around chicken. Sprinkle with za'atar and roast until chicken is browned and cooked through, 45–55 minutes.

Meanwhile, melt butter in a small skillet over medium-high heat. Add pine nuts and cook, stirring often, until butter foams, then browns, and nuts are golden brown (be careful not to burn), about 4 minutes; season with salt.

Slice chicken breasts, if desired. Serve chicken with roasted onion and lemon, topped with pine nuts, with green tahini sauce and lavash.

Do ahead: Chicken can be marinated 1 day ahead. Keep chilled.
