Ribollita Tuscan Twice Boiled Soup

In a large heavy-bottomed pot or Dutch oven, heat the olive oil over medium heat. Add the chopped onion, carrots, and celery. Cook gently for about 8-10 minutes, stirring occasionally, until the vegetables are softened and translucent. This is your soffritto, the flavor base.

Stir in the minced garlic and cook for another minute until fragrant. Add the chopped black kale and shredded savoy cabbage to the pot. Cook, stirring frequently, until the greens begin to wilt down, about 5-7 minutes. They will reduce significantly in volume.

Pour in the crushed tomatoes and the cooked cannellini beans (half whole, half mashed). The mashed beans will help thicken the soup. If using a Parmesan rind, add it now for extra savoriness. Season with salt and freshly ground black pepper to taste.

Add the vegetable broth to the pot. Bring the mixture to a gentle boil, then reduce the heat to low, cover, and let it simmer for at least 20-25 minutes. This allows the flavors to meld beautifully and the vegetables to become tender.

Remove the Parmesan rind if using. Arrange the stale bread slices over the top of the simmering soup, pushing them down gently so they soak up the liquid. Continue to simmer, uncovered, for another 10-15 minutes, allowing the bread to absorb the broth and soften, thickening the soup further.

Once the bread is fully incorporated and the soup is thick, remove the pot from the heat. The 'twice-boiled' aspect traditionally involves reheating the soup the next day, but for immediate serving, simply let it rest for 10-15 minutes. This resting period allows the flavors to deepen and the soup to achieve its characteristic consistency.

Ladle the hot Ribollita into bowls. Drizzle generously with a good quality extra virgin olive oil and garnish with fresh chopped parsley. Serve immediately as a hearty and comforting main course. Buon appetito!
