Ribollita

Ribollita — meaning "reboiled" — is a deeply peasant Tuscan dish born of frugality: leftover vegetable soup thickened with stale bread and reheated the next day, which paradoxically makes it better. It is one of Italy's most storied heirloom dishes, tracing back to medieval kitchens.

Serves: 6

Ingredients

• 400g (14 oz) dried cannellini beans, soaked overnight (or 2 x 400g cans, drained)
• 300g (10.5 oz) cavolo nero (Tuscan kale / lacinato kale), stems removed, leaves roughly chopped
• 300g (10.5 oz) Savoy cabbage, roughly shredded
• 3 medium carrots, diced
• 3 stalks celery, diced
• 2 medium potatoes, peeled and diced into 2cm cubes
• 1 large onion, diced
• 400g (14 oz) canned whole tomatoes, crushed by hand
• 4 garlic cloves, minced
• 2 sprigs fresh rosemary
• 4 sprigs fresh thyme
• 4 tbsp extra-virgin olive oil, plus more to finish
• 300g (10.5 oz) stale country bread (pane sciocco or sourdough), torn into chunks
• 1.5 litres (6 cups) vegetable stock or water
• Salt, black pepper, and chili flakes

Instructions

1. If using dried beans, simmer them in unsalted water with a sprig of rosemary for 60–75 minutes until tender. Reserve the cooking liquid. If using canned beans, skip this step.
2. Heat 4 tbsp olive oil in a large heavy pot over medium heat. Add onion, carrots, and celery. Cook, stirring occasionally, for 12 minutes until very soft and beginning to color. Add garlic, rosemary, and thyme; cook 2 minutes.
3. Add tomatoes, potatoes, cavolo nero, and cabbage. Stir well and cook for 5 minutes. Season generously with salt, pepper, and a pinch of chili flakes.
4. Mash about one-third of the cooked beans roughly and stir into the pot along with the remaining whole beans. Add the vegetable stock. Bring to a boil, then reduce to a steady simmer for 40 minutes until all vegetables are very tender.
5. Stir in the torn stale bread, pushing it below the surface. It will disintegrate into the soup, thickening it dramatically. Simmer 10 more minutes, stirring regularly.
6. Remove herb sprigs. For true ribollita, cool and refrigerate overnight, then reheat ("reboil") the next day, adding a splash of stock if too thick.
7. Serve in deep bowls with a very generous drizzle of your best extra-virgin olive oil and cracked black pepper.

Cook's Notes: The dish must be very thick — almost porridge-like — not a thin soup. Cavolo nero (Tuscan kale) is the authentic choice and worth seeking out. Reheating the next day genuinely improves the flavor, as the bread fully integrates and the flavors meld.
