Tuscan White Bean and Kale Soup with Farro

Why it works

This bowl leans on the volumetrics principle: a large, brothy, water-heavy portion delivers stomach-filling mass at very low energy density (well under 0.6 kcal per gram), so gastric stretch receptors signal fullness before many calories are consumed. Cannellini beans and farro together supply about 14 g of fiber, including viscous soluble fiber that slows gastric emptying and beta-glucan-style gelling that flattens the glucose curve, while the beans' protein and slow carbohydrates extend satiety for hours. Kale adds bulky insoluble fiber and micronutrients for almost no calories.

Ingredients

• 2 x 15 oz cans cannellini beans, drained and rinsed
• 1 bunch curly kale (about 200 g), stemmed and torn
• 2 medium carrots, diced
• 2 celery stalks, diced
• 1 medium onion, diced
• 3 cloves garlic, minced
• 1 x 14 oz can diced tomatoes
• 80 g dry farro
• 2 tbsp olive oil
• 1.2 liters (5 cups) low-sodium vegetable broth
• 1 tsp dried oregano
• 1 bay leaf
• 24 g grated Parmesan, for serving
• Salt, black pepper, and a pinch of chili flakes

Method

1. Warm the olive oil in a large pot over medium heat and sweat the onion, carrot, and celery with a pinch of salt until softened, about 8 minutes, then add the garlic, oregano, and chili flakes and cook 1 minute.
2. Stir in the diced tomatoes and cook 3 minutes until slightly jammy.
3. Add the farro, bay leaf, and broth; bring to a boil then reduce to a simmer and cook 20 minutes until the farro is nearly tender.
4. Add the cannellini beans and simmer 5 minutes; for a creamier body, mash a ladleful of beans against the pot and stir back in.
5. Fold in the kale and cook 4 to 5 minutes until wilted and silky; season with salt and plenty of black pepper and remove the bay leaf.
6. Ladle into bowls and finish each with a light shower of Parmesan and a drizzle of olive oil if desired.
