Roll the dough into a ball and place it in a clean, oiled bowl, cover with a dish towel. Let it rise at room temperature for 40 minutes, or until doubled in size.
Divide it into thirds and divide each third into three pieces. Roll each piece until 25 cm long, then braid. To do this, on a clean surface, position three lengths of dough side by side and press the lengths together at the end furthest away from you so they hold in one piece. Braid the lengths into a plait, then press the bottom ends together to seal. Repeat with the remaining dough to make three loaves.
Arrange the three challah on a three baking sheets, cover with a dish towel and leave to prove in a warm place for 35 minutes or until doubled in size.
Preheat oven to 170°C. Brush the risen loaves with beaten egg and sprinkle 1 tablespoon of za’atar on each loaf. Bake for about 22 minutes, or until they are golden brown. Let the loaves cool for at least 1 hour before eating.
