Mavželj is a traditional dish originating from the Upper Carniola and Slovene Carinthia regions. The dish is usually made with a combination of pork (head, lungs, brains), cornmeal, onions, and spices. The offal is chopped and mixed with cooked polenta, spices, and sautéed onions.

The mixture is shaped into a fist-sized ball and wrapped in pork net before it's baked in special earthenware baking molds. In the past, the dish was made on holidays, and nowadays, it's also made with beef, turkey, chicken, or soy. If desired, eggs, bread, and rice can also be added to the mixture.
