If you keep dried beans, garlic, and a knob of Parmesan rind in the house, you're 45 minutes from this soup any night of the week.

It's the kind of bowl that reads as plain on paper and lands as deeply satisfying in real life. A glug of good olive oil on top is non-negotiable.

Ingredients

  • 3 tbsp olive oil, plus more to finish
  • 1 yellow onion, diced (about 1 cup)
  • 6 garlic cloves, thinly sliced
  • 1 tsp fennel seeds, lightly crushed
  • Pinch of red pepper flakes
  • 2 (15 oz / 425 g) cans cannellini beans, drained but not rinsed
  • 1 Parmesan rind (about 2-inch piece), optional but recommended
  • 4 cups (960 ml) vegetable or chicken stock
  • 1 bunch Tuscan kale, stems removed, leaves torn
  • Juice of ½ lemon
  • Kosher salt and black pepper
  • Grated Parmesan, to serve

Steps

  1. 1Warm the oil in a heavy pot over medium-low. Add the onion and a pinch of salt; cook gently until soft and translucent, 8–10 minutes.
  2. 2Add the garlic, fennel seeds, and pepper flakes. Cook just until the garlic smells sweet, 1–2 minutes.
  3. 3Add about 1 cup of beans and mash them into the pot with a spoon, this is your thickener. Stir in the rest of the beans, the Parmesan rind, and the stock.
  4. 4Simmer 20 minutes, partly covered, so the broth thickens slightly and the beans get creamy at the edges.
  5. 5Stir in the kale and cook 3–4 minutes until just collapsed and tender.
  6. 6Fish out the rind. Add the lemon juice, taste, and adjust salt, beans need more than you think. Serve with grated Parmesan and a heavy pour of olive oil.

Notes

Use the bean liquid for body: drain the beans but keep ½ cup of liquid and add it with the stock.
