Traditional Pasta e Fagioli

Why This Traditional Pasta e Fagioli Works

As the pot heats, the onion and garlic soften in the olive oil and lose their sharp bite. They start to taste sweeter and give the oil their taste, so everything that goes in later picks that up. After a few minutes, the carrot and celery begin to soften too. They don’t go mushy right away, but they loosen up so they can finish cooking gently in the broth.

Once the tomatoes go in and simmer, their juices mix with the oil and vegetable juices and thin out. Then the beans and broth are added, and the beans sit in that hot liquid. Some of the starch from the beans slowly slips into the broth, so the soup starts to feel a little thicker and more cozy instead of watery.

When the ditalini pasta cooks right in the pot, its starch also moves into the broth. The pasta soaks up the tomato-broth mix, and at the same time, the broth clings more to each piece. By the time the pasta is tender, the soup has a fuller body, and the Parmesan on top melts slightly and sticks to the pasta and beans, giving each spoonful a creamy feel.

Mistakes To Avoid

Letting the onion and garlic brown too much at the start can throw the whole soup off. The garlic turns bitter and the onion gets a harsh, burnt edge, so the broth ends up tasting sharp and slightly burnt instead of mellow and savory.

Adding the pasta too early, then letting the pot sit on the heat, makes the ditalini swell and break apart. The starch leaks into the broth, so the soup turns thick and gummy, and the pasta pieces lose their shape and bite.

Skipping the step of sautéing the carrot and celery long enough leaves them too hard. They stay crunchy in the finished soup and feel separate from the broth, instead of soft and tender in each spoonful.

Pouring in all the salt before the soup simmers can backfire. As the liquid reduces and the pasta releases starch, the broth concentrates, and the final soup can end up noticeably too salty with no easy way to fix it.
