Timballo di anelletti is a traditional casserole originating from Sicily, and it's particularly popular in Palermo. There are a few variations across the island, but the dish is usually made with a combination of anelletti (small ring-shaped pasta), eggplants, prosciutto cotto or mortadella, cheese such as pecorino, caciocavallo, or mozzarella, and a meat ragu consisting of beef, pork, tomatoes, onions, celery, carrots, olive oil, peas, basil, salt, and pepper.
A bundt pan is typically lined with sliced of fried or baked eggplants, boiled pasta, meat sauce, grated pecorino, mortadella or cooked ham, and a final layer of mozzarella. The process is repeated one more time, and before baking, the bundt pan is flipped over.
