The primary ingredient in a traditional moussaka dish is eggplant. This Mediterranean casserole originated from Greece and is known for its rich, layered flavors. In addition to eggplant, moussaka typically includes ground meat, often lamb or beef, and a béchamel sauce made from milk, butter, and flour. The eggplant is usually sliced, salted, and sometimes fried or baked before being layered with the meat and topped with the béchamel before baking the entire dish. Moussaka is celebrated for its hearty texture and is often served as a staple in Greek cuisine, showcasing the region's culinary heritage.
