On the cut side of the eggplant, score the flesh deeply (but not all the way through) with a sharp knife diagonally about 1 inch apart, and rotate the eggplant to slice it into a diamond pattern. Rub za’atar liberally on the cut side. Sprinkle with salt and pepper. Drizzle oil liberally to both sides of the eggplant and place them cut-side down on a baking paper-lined large pan.
Roast for about 35 to 40 minutes until the back of the halved eggplants look collapsed or puckered.
You may serve the roasted eggplants on top of the labneh or serve the labneh on the side. Enjoy this meal with couscous, flatbread and tabbouleh!
