Timpana is a pasta casserole originating from Malta. It's prepared with a combination of puff pastry sheets, macaroni or penne pasta, beef, pork, chicken liver, bacon, onions, garlic, grated cheese, eggs, tomatoes, stock, and butter. The onions and garlic are sautéed in olive oil with the bacon, livers, and ground pork and beef.
The combination is covered with the stock and simmered with tomato paste or tomato purée. The pasta is cooked and mixed with grated cheese and beaten eggs. A baking dish is lined with the puff pastry sheets, then filled with the pasta and the sauce.
