Why I Love this Tuscan White Bean Soup
This white bean sausage soup is part of my SOUP-er Simple Series. If you’ve been following along you know that means it has a short ingredient list, quick cook time, and loads of flavor.
I love how this soup recipe is cozy and comforting while also being light and healthy. The true definition of healthyish! It features bold, flavorful ingredients like Italian sausage, garlic and red pepper flakes while also being packed with nutritious ingredients like fiber-rich kale, white beans and fennel.
To keep the ingredient list short I used only the most necessary ingredients. And instead of calling for a fresh herb I recommend using the fennel fronds from the fennel bulbs we’re using in the soup. Fennel fronds add a lovely note of fresh flavor to this Italian white bean soup.
Ingredients in Sausage Kale White Bean Soup
The name gives most of the ingredients away, but here’s the full list! Keep in mind I don’t list oil, salt and pepper.
- Yellow onion, white onion would be a great substitute.
- Crushed red pepper flakes, if you don’t have red pepper flakes, you can use black pepper. And if you prefer a more mild soup, skip this altogether.
- Bulk Italian sausage, hot or mild work here but I find hot adds more flavor and character.
- Fennel bulbs, reserve the fronds for use as an herb at the end. If your fennel bulbs come trimmed, without the stalks and fronds, consider finishing the soup with chopped fresh parsley.
- Fresh garlic
- Low-sodium chicken broth, homemade broth or stock would be absolutely delicious here if you have it.
- Tuscan kale, you can use any dark leafy green you prefer or have on hand.
- Canned cannellini beans, canned beans are a weeknight lifesaver! Great Northern beans are also a great option.
- Whole milk, if you need this to be dairy-free you can substitute any unsweetened, unflavored nut milk or canned coconut milk. And if you want something a bit more comforting and decadent, feel free to use half-and-half or a combo of milk and half-and-half.
- White wine vinegar is important for balancing all of the flavors. If you find most soup recipes fall flat, they likely need a splash of some sort of acid (vinegar or citrus juice) at the end.
- Thick-sliced bread & Parmesan cheese for the Parmesan toasts, which are totally optional!
Storage tip: store this Italian white bean soup in an airtight container in the refrigerator for up to 1 week.
FAQ & Test Kitchen Tips
My answer may be contrary to what you expect—this isn’t for decreasing sodium levels. Low-sodium broth is important for controlling the seasoning level. I'd rather you season every component as you go instead of relying on broth to season everything. If you season in stages, the entire soup, and all of its components, will taste better.
Swiss chard, collard greens and mustard greens are all great options. If you don’t like hardy greens you can use fresh spinach instead.
Red potatoes, parsnips, or celery would all be great options. They will have different cook times, so keep an eye on the soup and check for tenderness occasionally.
You could definitely use ground pork, turkey or chicken. I would opt for 85% lean ground meat for the best flavor (you can always drain off some of the drippings). I would then add some crushed fennel seed (if you have it), a bit more red pepper flakes and a dash of ground nutmeg (again, if you have it) to the meat while it cooks. This will give you that "sausage" flavor.

- 1 tablespoon olive oil
- 1 yellow onion, diced
- Kosher salt
- Crushed red pepper flakes
- 1 pound bulk Italian sausage, hot or mild
- 2 fennel bulbs, fronds reserved
- 4 large cloves garlic, chopped (2 tablespoons)
- 4 cups low-sodium chicken broth
- 1 small bunch Tuscan kale, stems removed, leaves torn into bite-size pieces (about 9 cups)
- 2 (14.5-ounce) cans cannellini beans, drained and rinsed
- 2 cups whole milk, warmed
- 2 tablespoons white wine vinegar
Parmesan Toast, optional
- 6 thick-cut slices whole-wheat or sourdough bread
- 1 cup shredded Parmesan
- Heat oil in a large pot or Dutch oven over medium.
- Add onion, ¼ teaspoon salt and ¼ teaspoon red pepper flakes; cook until softened and translucent, about 5 minutes.
- Add sausage and cook, crushing with a wooden spoon, until cooked through and browned, 6–8 minutes. Drain all but 2 tablespoons drippings from pot.
- Meanwhile, quarter fennel bulbs lengthwise, then slice into ½ inch-thick slices (you should get 4–5 cups). Add fennel and garlic to pot and cook 2 minutes.
- Add broth, bring to a boil, then reduce to a simmer over medium and cook until fennel is nearly tender, about 5 minutes.
- Meanwhile make Parmesan Toasts. Heat broiler to high with rack set 6-inches from element. Arrange bread slices on a baking sheet and broil until lightly toasted, about 2 minutes. Flip bread and top with Parmesan, dividing cheese evenly between toasts. Broil toasts until Parmesan is melty and starting to brown, 2–3 minutes; set aside.
- Stir kale, beans and milk into soup; cook until kale is wilted, about 2 minutes. Stir in vinegar and season with additional salt, red pepper flakes and vinegar to taste.
- Serve soup with Parmesan toast and reserved fennel fronds
If you've got a Parmesan rind floating around in the fridge or freezer, plop that in as the soup simmers. It will infuse the broth with salt, savory goodness.
