Creamy Tuscan White Bean Soup with Sausage and Kale
This comforting Tuscan white bean soup features browned Italian sausage, creamy cannellini beans, and hearty kale simmered in a savory tomato and parmesan broth.
There is nothing more restorative than a bowl of hearty Tuscan white bean soup when the weather turns sharp. This version isn't just a watery vegetable broth; it’s a thick, soul-warming meal built on a foundation of browned Italian sausage and a rich soffritto of onion, carrot, and celery.
To achieve a truly creamy Tuscan white bean soup, we gently mash a portion of the cannellini beans directly into the pot and finish the dish with a splash of heavy cream. It’s an Italian white bean and kale soup that feels sophisticated enough for a dinner party but is simple enough for a Tuesday night.
The secret weapon here is the parmesan rind. Dropping one into the simmering broth adds a salty, umami depth that salt alone cannot replicate. Paired with San Marzano tomatoes and a finish of high-quality olive oil, this soup is a masterclass in pantry cooking.
Ingredients
The Base
- 1 lb (450g) Italian pork sausage, casings removed
- 2 tablespoons extra virgin olive oil, plus more for serving
- 1 large yellow onion, finely diced
- 2 medium carrots, peeled and diced
- 2 stalks celery, diced
- 4 cloves garlic, minced
- 1 tablespoon tomato paste
The Pot
- 2 cans (15 oz / 425g each) cannellini beans, drained and rinsed
- 1 can (14.5 oz / 411g) crushed San Marzano tomatoes
- 6 cups (1.4L) high-quality chicken stock
- 1 large parmesan rind
- 1 teaspoon dried oregano
- 1/2 teaspoon red pepper flakes
- 1 bunch Tuscan kale (lacinato), stems removed and leaves chopped
- 1/2 cup (120ml) heavy cream
- Kosher salt and freshly cracked black pepper to taste
Instructions
- 1
Brown the sausage in a large Dutch oven over medium-high heat, breaking it into small crumbles with a wooden spoon until cooked through and golden.
- 2
Remove the sausage with a slotted spoon and set aside, leaving the rendered fat in the pot (add a tablespoon of olive oil if the pot looks dry).
- 3
Add the onion, carrots, and celery to the pot, sautéing for 6-8 minutes until the vegetables are softened and the onions are translucent.
- 4
Stir in the garlic, tomato paste, oregano, and red pepper flakes, cooking for 1 minute until the paste darkens and becomes fragrant.
- 5
Pour in the chicken stock and crushed tomatoes, scraping the bottom of the pot to release any browned bits (fond).
- 6
Add the rinsed cannellini beans and the parmesan rind to the liquid, then return the browned sausage to the pot.
- 7
Bring the soup to a boil, then reduce heat to low and simmer, partially covered, for 20 minutes.
- 8
Use the back of a spoon to mash about 1/2 cup of the beans against the side of the pot to thicken the broth naturally.
- 9
Stir in the chopped kale and simmer for another 5 minutes until the leaves are tender and bright green.
- 10
Remove the parmesan rind, stir in the heavy cream, and season generously with salt and pepper.
- 11
Ladle into bowls and finish with a heavy drizzle of extra virgin olive oil and freshly grated parmesan cheese.

Tips
- → Don't toss your parmesan rinds! Keep them in a zip-top bag in the freezer specifically for soups and stews like this one.
- → If you prefer a thicker texture, you can take one cup of the soup (beans and broth) and run it through a blender before stirring it back into the pot.
- → Tuscan kale (also called Lacinato or Dinosaur kale) is preferred over curly kale because it has a more tender texture and deeper flavor when simmered.
- → Always taste for salt at the very end. The parmesan rind and sausage provide a lot of sodium, so you may need less added salt than you think.
FAQ
Can I make this Tuscan white bean soup vegetarian?
Yes. Omit the sausage, use vegetable broth, and add a teaspoon of smoked paprika or liquid smoke to replicate the savory depth of the meat.
How do I store and reheat leftovers?
Store in an airtight container in the fridge for up to 4 days. Reheat gently on the stovetop. If the soup has thickened too much overnight, add a splash of water or broth to loosen it.
Can I freeze this soup?
You can freeze it, but for the best texture, freeze it before adding the kale and cream. Add those fresh when you reheat the thawed soup.
Why is my kale still tough?
Make sure you have removed the woody center ribs from the kale leaves. If it's still tough, simmer for an additional 5-10 minutes; unlike spinach, kale holds up well to longer cooking.
