For the breaded zucchini, wash, dry and cut the zucchini into 5 mm thick slices. In a plate, beat the egg. In another plate, place the breadcrumbs and the flour for breading.
Salt the zucchini slices and sprinkle them with garlic powder, then coat them in flour-egg and panko. Heat the oil with the clarified butter, not too hot, and fry the breaded slices until light yellow.
