Bolognese (Italian Meat Sauce)

Bolognese (ragu alla bolognese) is the rich, meaty sauce from Bologna, Italy - a slow-simmered combination of ground beef and pork, tomatoes, wine, milk, and aromatics that develops incredible depth over hours of gentle heat. Sous vide is ideal for bolognese because the sauce needs sustained low heat without scorching, which is exactly what a sealed bag in a water bath provides. No stirring, no watching, no burnt bottom. The key to authentic bolognese is patience and restraint. The sauce should be meaty and rich, not tomato-heavy. Traditional recipes use only a small amount of tomato paste and crushed tomatoes - the meat and the long cook are the stars. At 155°–165°F for 4–8 h, the ground meat breaks down completely and the flavors meld into something that quick stovetop versions cannot achieve. The sealed bag also prevents evaporation, keeping the sauce at the right consistency without reduction. The soffritto (finely diced carrot, celery, and onion) must be deeply browned on the stovetop before adding to the bag. This is the flavor base and it cannot be built inside the bag. Use this guide for timing, meat ratios, and the finishing steps that turn good bolognese into extraordinary ragu.

Longer cooking times develop deeper flavors and tender meat.

Ground beef should reach at least 160°F / 71°C per USDA guidelines. Cooking at 165°–170°F for 6–18 h ensures complete pasteurization and flavor development.
