Pin There's something about the way sausage hits a hot pot that makes you stop and pay attention—that immediate sizzle and the kitchen filling with the scent of fennel and black pepper. I discovered this soup one October when my neighbor dropped off a bundle of kale from her garden, and I had half a package of Italian sausage sitting in my fridge looking purposeful. What started as a way to use both became the kind of soup I now make without thinking, the one that tastes like someone who knows what they're doing in the kitchen decided to feed you.
I made a massive pot of this for my book club one rainy evening, and I watched people go quiet when they tasted it—not the performative quiet of politeness, but the real kind where you're too busy enjoying yourself to make conversation. One friend asked for the recipe and said it reminded her of a place her grandmother used to take her in Florence. That moment taught me that the best meals are the ones that somehow land differently for everyone who eats them.
Ingredients
- Italian sausage, 1 lb: This is where the soul of the soup lives—the fat renders out and carries all its flavor into the broth, so don't skip browning it properly or use the leanest option you can find.
- Yellow onion, carrots, and celery: The holy trinity that Italian cooking depends on; they soften into the background but build the foundation everything else sits on.
- Garlic, 3 cloves: Added after the vegetables soften so it doesn't burn and turn bitter, which I learned the hard way early on.
- Kale, 2 cups: Strip it from the stems and chop it roughly—it wilts down so much you'll wonder where it went, but that's the point.
- Yukon Gold potatoes: These hold their shape and have a subtle sweetness that balances the herbiness; waxy potatoes are your friend here, not the floury kind.
- Cannellini beans, 2 cans: Rinsing them removes the starchy liquid and keeps your broth from getting gluey.
- Chicken broth, 6 cups: Use low-sodium because you're going to taste this as it reduces, and you want control over the salt.
- Dried oregano, basil, thyme: A measured hand with dried herbs makes the difference between soup that tastes intentional and soup that tastes like someone sneezed spice into it.
- Red pepper flakes, crushed: Optional but transformative if you want heat that builds as you eat rather than hits you upfront.
- Extra-virgin olive oil: Use good oil here because you're not cooking it to death; it's part of the final taste.
- Parmesan cheese: For serving, though some people swear by dropping a rind in while simmering and fishing it out at the end.
Instructions
- Brown the sausage with purpose:
- Heat olive oil in a large pot over medium heat and add your sausage, breaking it into small pieces as it cooks. You want it fully browned and cooked through, about 5 to 6 minutes, because the rendered fat is going to season everything that comes next.
- Build your base with the soffritto:
- Transfer the cooked sausage to a plate, leaving that precious fat behind. Toss in your diced onion, carrots, and celery, stirring occasionally until they start to soften and the kitchen smells like something important is happening—about 5 minutes total.
- Add garlic and let it wake up:
- Stir in your minced garlic and cook for just 1 minute, until you can smell it distinctly but before it turns brown.
- Combine everything and bring to a simmer:
- Return the sausage to the pot and add potatoes, cannellini beans, tomatoes if you're using them, broth, and all your dried herbs. Stir everything together, bring it to a boil, then lower the heat to a gentle simmer with the lid on.
- Cook until the potatoes surrender:
- Let this sit for about 20 minutes—the potatoes will soften, the flavors will marry, and you can step away and do something else for a bit.
- Finish with the kale:
- Stir in your chopped kale and cook uncovered for 5 to 7 minutes until it's completely wilted and tender. Taste as you go and adjust salt and pepper until it tastes like your version of this soup.
Pin There's a particular comfort in eating a soup that feels both simple and substantial, where you're getting vegetables and beans and protein all in one bowl. This one has that quiet generosity to it—the kind of dish that doesn't try to impress you but somehow does anyway.
The Sausage Question
The choice between mild and spicy sausage changes the entire personality of this soup, and I've made it both ways depending on my mood. Mild sausage lets the herbs and vegetables shine and keeps things cozy and approachable. Spicy sausage builds heat that gets more interesting with each spoonful, especially if you add red pepper flakes on top of that. Neither choice is wrong—it's about what you're hungry for that day.
Making It Your Own
Once you understand how this soup works, you start seeing variations everywhere. Some people add a parmesan rind to simmer alongside everything else and fish it out before serving, which deepens the umami in a way that feels like a secret. Others use white beans exclusively or mix in some diced tomatoes for brightness. The base is flexible enough to adapt to what you have on hand and what your family actually wants to eat.
Serving and Storage Wisdom
Serve this soup hot with crusty bread for soaking up the broth, and if you want to grate fresh Parmesan over the top, that's when it becomes the kind of meal you remember. The leftovers actually improve as they sit in the refrigerator because the flavors deepen and the potatoes absorb more of the broth, making it even better the next day.
- This keeps refrigerated for up to 3 days, and you can reheat it gently on the stove without losing its character.
- If you want to make it vegetarian, swap in plant-based sausage and vegetable broth, and it works beautifully.
- Crusty bread on the side transforms this from a soup into something that feels like a proper meal.
Pin This is the kind of soup that earns its place in your regular rotation because it's humble enough to make on a Wednesday night but impressive enough to serve when people you actually care about are coming over. Once you make it, you'll understand why.
Recipe Q&A
- → Can I make this soup vegetarian?
Yes, substitute plant-based sausage for Italian sausage and use vegetable broth instead of chicken broth. The flavors and texture remain excellent.

- → Can I freeze this soup?
Yes, freeze in portions for up to 3 months. Thaw overnight in the refrigerator and reheat gently on the stove.
- → What type of sausage works best?
Italian sausage either mild or spicy works beautifully. Remove casings before cooking to crumble the meat into the soup base.

Absolutely. Use about 1 tablespoon fresh herbs for every teaspoon of dried. Add them in the last 5 minutes of cooking to preserve flavor.
