Ragù Napoletano, also known as Neapolitan ragù, is a slow-cooked meat sauce that is a staple in Neapolitan cuisine. It is made with a combination of meats such as beef, pork, and veal, along with tomatoes, onions, garlic, and herbs. The sauce is simmered for several hours, allowing the flavors to meld together and create a rich and hearty sauce.
