The primary ingredient in a traditional Greek moussaka is eggplant. This savory dish typically consists of layers of sliced eggplant, which is often planked, fried, or baked, combined with a spiced meat sauce, commonly made with ground lamb or beef. It is then topped with a creamy béchamel sauce before being baked until golden brown. While eggplant is the star of the dish, potatoes, tomatoes, and spices also play significant roles in creating its rich flavor profile. Moussaka is beloved in Greece and has various regional variations across the Mediterranean.
