Ribollita: How Stale Bread Became Tuscany's Most Beloved Soup

Soak the dried cannellini beans in a large bowl of cold water overnight, or for at least 8 hours. Drain and rinse well.

Put the soaked beans in a large pot with 2 litres of cold water, 1 rosemary sprig, 2 sage leaves, and a drizzle of olive oil. Bring to a boil, skim any foam, then reduce to a steady simmer. Cook for 60–75 minutes until the beans are completely tender. Season with salt only in the final 10 minutes. Drain, reserving all of the cooking liquid.

Transfer one-third of the cooked beans to a bowl and mash roughly with a fork until a coarse paste forms. Set aside with the whole beans and all the reserved cooking liquid.

Warm 60ml of olive oil in a large heavy pot over medium heat. Add the diced onion, carrots, and celery. Cook for 10–12 minutes, stirring occasionally, until softened and lightly golden.

Slice 2 garlic cloves and add to the pot. Cook for 2 minutes. Add the canned tomatoes, crushing them into the pot by hand. Add the remaining rosemary sprig, 4 sage leaves, and the Parmigiano rind if using. Stir and cook for 5 minutes.

Strip the tough stems from the cavolo nero and roughly chop them; roughly chop the leaves separately. Add the stems to the pot and cook for 5 minutes. Add the savoy cabbage and cavolo nero leaves. Stir and cook for another 5 minutes to wilt.

Add the whole beans, mashed beans, and 800ml of reserved bean cooking liquid. Top up with vegetable stock so everything is just covered. Bring to a simmer and cook uncovered for 20 minutes.

Remove the rosemary, sage, and Parmigiano rind. Tear the stale bread into rough 5cm chunks and stir into the soup. Cook over low heat for 10 minutes, stirring frequently, until the bread softens and begins to break down. Adjust salt and pepper.

Remove from the heat. Let the soup cool to room temperature, then refrigerate overnight. This rest is what transforms the dish — the bread will continue to hydrate and integrate into the broth.

The next day, reheat the soup over medium-low heat, stirring vigorously. The bread breaks down fully and the soup thickens to an almost porridge-like consistency. Add a splash of water if it seems too stiff. Simmer for 15–20 minutes. Taste and adjust seasoning.

Ladle into bowls and finish each serving with a generous pour of raw extra-virgin olive oil and a few grinds of black pepper. This final olive oil is not garnish — it is part of the dish.
