The primary ingredient in traditional moussaka is eggplant, which is key to this savory dish that originated in the Mediterranean, particularly in Greece. In authentic moussaka, the eggplants are usually sliced, salted, and often lightly fried or baked to soften them before layering with other ingredients. Moussaka typically consists of layers of sautéed eggplant, a rich meat sauce (often made with ground lamb or beef), and topped with a creamy béchamel sauce. This combination creates a comforting and flavorful meal that is both hearty and satisfying. Moussaka is often served as a main course during gatherings and special occasions.
