Moussaka (Musaka) is a traditional Greek dish but it is also a staple in lots of other Eastern European cuisines. The recipe I am sharing with you is how my family and other Bulgarian families have been making moussaka for decades. Made with cubed potatoes, ground beef, tomato sauce, onion, and seasonings. This easy 4-ingredients Moussaka is a warm and comforting meal and it is perfect for a family dinner.
