Bolognese sauce, or Italian ragù alla bolognese, is a rich, slow-cooked meat-based sauce originating from Bologna, Italy. It's traditionally made with a soffritto base (onion, celery, carrot), ground meat (often a mix of beef and pork), tomatoes, wine, and milk or cream, simmered for hours to develop deep flavor. It's most famously paired with tagliatelle pasta rather than spaghetti.
This sauce is primarily a source of protein and fat from the meat, with relatively low carbs unless served with pasta. A typical serving (about 1/2 cup) provides iron, B vitamins, and lycopene from tomatoes, with a calorie range of roughly 150-250 depending on meat fat content and added dairy.
Authentic ragù alla bolognese is a protected recipe in Bologna, with specific guidelines emphasizing a meat-forward, tomato-light profile. Nutritionally, the long cooking process helps break down proteins for easier digestion, and the combination of meat with tomato and wine creates a complex flavor profile without relying on heavy spices.
