Classic Spaghetti Bolognese

Why This Classic Spaghetti Bolognese Works

At the start, the onion, garlic, carrot, and celery sit in the warm olive oil and slowly soften. As they cook, they lose their sharp bite and start to taste sweeter and milder. By the time the ground beef goes in, those vegetables are soft enough to mix right into the meat instead of staying in hard little chunks. Browning the beef gives it a firmer texture, so it doesn’t feel mushy in the sauce.

After the meat browns, the tomato paste cooks on the bottom of the pan for a minute. It goes from bright and sharp to darker and thicker. When the red wine is poured in, it loosens everything stuck to the pan and thins the paste. Then the crushed tomatoes, herbs, salt, and pepper go in and the whole pan just quietly bubbles. During that 30–40 minute simmer, the sauce slowly thickens, the tomatoes lose their raw taste, and the beef soaks up the tomato and herb taste. By the end, the sauce clings to the spaghetti instead of sliding off, and the Parmesan melts over the top and softens into the hot sauce.

Mistakes To Avoid

Cranking the heat too high when browning the beef makes the outside of the meat go dark fast while the inside steams in its own juices. The pan fills with liquid, the meat turns a bit rubbery, and the sauce ends up watery instead of rich and thick.

Skipping the step of really softening the onion, carrot, and celery leaves the vegetables still a bit hard when the sauce is done. They don’t break down into the sauce and instead sit as crunchy bits that feel out of place with the soft pasta and meat.

Pouring in the wine and then rushing past the simmer means the alcohol doesn’t have time to cook off. The liquid stays sharper and thinner, and the sauce doesn’t cling well to the spaghetti.

Letting the sauce simmer with the lid off the whole time on a strong bubble can drive off too much liquid. The sauce then turns pasty and heavy, and it sits in clumps on top of the spaghetti instead of coating the strands.
