Za’atar Roasted Chicken with Black Garlic Tahini and Sumac Onions, by Chef Zachary Engel

The stuff:

Black garlic tahini

• 1/4 cup fresh lemon juice
• 2 medium garlic cloves, grated
• 3 peeled black garlic cloves 
• 3/4 teaspoon kosher salt
• 3/4 cup tahini 
• 3/4 cup ice water

Sumac onions

• 1 medium-size red onion, thinly sliced
• 1/4 cup red wine vinegar
• 1 tablespoon Never Not Eating Sumac S&P

Za’atar chicken

• 1 (4-pound) whole chicken
• 2 tablespoons kosher salt
• 1 1/2 tablespoons Never Not Eating Za’atar
• Black Garlic Tahini

The method:

1. Combine lemon juice and grated garlic in a blender; let stand 15 minutes. Using the flat side of a knife, smash black garlic cloves on a cutting board, and scrape to form a paste. Add black garlic paste and salt to blender; puree until mostly smooth and black garlic is very finely chopped, 2 to 3 minutes.
2. Place tahini in the bowl of a stand mixer fitted with the whisk attachment; beat on high speed until smooth and creamy, 4 to 5 minutes. Decrease the speed to medium, and slowly drizzle in the black garlic mixture. (Mixture will thicken but will smooth out again after adding water.) With mixer running, slowly drizzle in 3/4 cup cold water until fully incorporated. Increase speed to high, and beat until mixture is smooth, glossy, and fluffy, about 5 minutes.
3. Preheat oven to 450°F, and line a large baking sheet with heavy-duty aluminum foil. Place chicken, backbone side up, on a baking sheet. Using kitchen shears, cut along each side of the backbone; remove and discard backbone. Flip the chicken breast side up, and push down on the breast to flatten. Season both sides of the chicken evenly with salt. Roast chicken, breast side up, in preheated oven until a thermometer inserted in the thickest portion registers 140°F, 40 to 45 minutes, rotating pan after 20 minutes. Meanwhile, make the sumac onions.
4. Toss together onion, vinegar, Never Not Eating Sumac S&P in a large bowl until onions are well coated. Set aside until ready to serve.
5. Remove chicken from oven. (Do not turn the oven off.) Tilt the pan slightly to collect rendered juices into a baster or large spoon. Baste chicken skin with drippings, and sprinkle with Never Not Eating Za’atar. Return chicken to oven, and roast at 450°F until a thermometer inserted in the thickest portion of chicken registers 155°F, 5 to 10 minutes. Let chicken rest 15 minutes before carving. Serve with sumac onions and black garlic tahini.
