While both spaghetti meat sauce and bolognese are popular Italian pasta sauces, there are some key differences between the two. Spaghetti meat sauce is typically made with ground beef, tomato sauce, and basic seasonings such as garlic and herbs. On the other hand, bolognese is a traditional slow-cooked sauce that originated in Bologna, Italy. It is made with a combination of ground beef, pork or veal, along with vegetables, tomatoes, and wine. It also contains milk or cream to give it a richer and creamier flavor.
