What is "spaghetti Bolognese"?

Spaghetti Bolognese is an Italian dish that typically consists of spaghetti noodles topped with a tomato-based meat sauce. The sauce is made by sautéing ground beef or pork in a mixture of onions, garlic, and olive oil, before adding canned tomatoes, tomato paste, and a variety of herbs and spices such as basil and oregano. The sauce is then simmered until it thickens and the flavors meld together. The spaghetti noodles are cooked until al dente, then tossed with the sauce and served with grated Parmesan cheese on top. It can be customized to suit different tastes, with variations such as adding mushrooms, bell peppers, or red wine to the sauce.
