The main ingredient in a traditional moussaka is eggplant. This popular Mediterranean dish, particularly in Greek cuisine, features layers of sliced eggplant, along with ground meat (usually lamb or beef), onion, and tomatoes. The dish is often topped with a creamy béchamel sauce, which is made from milk, butter, and flour, contributing to its rich and satisfying texture. Variations of moussaka exist across the Mediterranean region, but the eggplant remains a staple component that provides depth and flavor. Moussaka is typically baked until golden brown and served as a hearty main course, showcasing Mediterranean culinary traditions.
