(Hearty, Garlicky, and Comfort in a Bowl)
There are some soups that just feel like home the moment they start simmering on the stove. This Portuguese Kale Soup is absolutely one of those soups.
Big pot. Simple ingredients. Incredible flavor.
This soup is rustic and hearty in the very best way. Smoky slices of linguica sausage, tender potatoes, creamy cannellini beans, and lots of chopped kale all simmer together in a garlicky broth that somehow tastes even better the next day. And the day after that.
If you’ve ever spent time in New England, you’ve probably come across some version of Portuguese kale soup. It’s a classic in many Portuguese communities and has found its way into kitchens and restaurants all over the region.
I love soups like this because they’re simple, nourishing, and meant to be shared. A big bowl of this soup with a piece of crusty bread on the side? That’s dinner done right.
What Is Portuguese Kale Soup?
Portuguese Kale Soup – often called Caldo Verde in Portugal – is a simple, rustic soup traditionally made with potatoes, greens, olive oil, and sausage. The soup originated in northern Portugal and has become one of the country’s most beloved comfort foods.
Over the years, Portuguese immigrants brought this soup with them to many places, including New England, where it became especially popular in Portuguese communities throughout Massachusetts and Rhode Island. Many families created their own versions using ingredients that were easier to find locally.
Some recipes use thinly sliced collard greens or kale, while others add beans for extra heartiness. The version I make in my kitchen leans into those cozy, hearty ingredients – smoky linguica, tender potatoes, fresh kale, and creamy cannellini beans simmered together in a garlicky broth.
Like so many traditional soups, every family seems to have their own way of making it. But one thing stays the same – it’s a simple, comforting soup meant to be shared around the table.
Why You’ll Love This Portuguese Kale Soup
• Hearty and comforting – Loaded with smoky linguica sausage, potatoes, cannellini beans, and tender kale, this soup is a complete meal in a bowl.
• Big flavor from simple ingredients – Garlic-forward linguica and a rich broth create incredible flavor with pantry staples.
• Naturally thick and satisfying – Puréeing a small portion of the potatoes gives the soup body without adding cream.
• Perfect for leftovers – Like many soups and stews, the flavors deepen overnight, making the next bowl even better.
Let’s Talk About the Ingredients:
One of the things I love most about Portuguese Kale Soup is how such simple ingredients come together to create incredible flavor. A handful of pantry staples, a good smoky sausage, and plenty of greens turn into a hearty, comforting pot of soup.
Let’s Talk About Linguica
The heart and soul of Portuguese Kale Soup is linguica – a smoky Portuguese sausage that brings incredible depth of flavor to the pot.
If you’ve never cooked with it before, think of it as a cousin to sausages like chorizo or andouille, but with its own personality.
While chorizo leans heavily on paprika and spice, and andouille carries that bold Cajun smokiness, linguica is wonderfully garlic-forward. And if you know me at all, you know garlic is basically my middle name.
The sausage is seasoned with plenty of garlic and spices, then smoked, giving it a rich flavor that melts right into the broth as it cooks.
When the linguica sautés in olive oil, it releases all those savory oils into the pan. That oil becomes the flavor base for the onions, garlic, potatoes, and kale that follow.
Around here I usually grab linguica at Stop and Shop (a local big super market), but many grocery stores carry it in the specialty sausage section. If you see it, grab it – it’s fantastic in soups, with eggs, or tossed with roasted potatoes. I grab a few extra and throw them in my freezer for a rainy day!
Cannellini Beans
Cannellini beans are the quiet little heroes of this soup.
These creamy white beans add body, heartiness, and a gentle earthy flavor that balances beautifully with the smoky linguica and tender kale. They soak up all that garlicky broth and make each spoonful feel a little more satisfying.
I usually reach for canned cannellini beans for convenience – just drain and rinse them before adding them to the soup near the end of cooking. They only need a few minutes to warm through.
Between the potatoes, beans, kale, and that garlicky linguica, this soup really is a complete meal in a bowl.
Yukon Gold Potatoes
Yukon Gold potatoes are perfect for this soup. They hold their shape nicely while simmering but also have a naturally creamy texture that helps give the broth some body.
In this recipe, a small portion of the cooked potatoes and broth are puréed and added back to the pot. This is an old-school trick that thickens the soup naturally without adding cream or flour. It keeps the soup rich and hearty while still letting all the other ingredients shine.
Fresh Kale
Kale is what gives this soup its signature look and flavor. Once it hits the hot broth it softens beautifully while still holding a bit of texture.
I like to remove the thicker stems and chop the leaves into roughly two-inch pieces before adding them to the pot. It might seem like a lot of kale at first, but it quickly cooks down and becomes perfectly tender in the soup.
Onion and Garlic
Every good soup starts with aromatics, and this one is no exception. The onion and garlic sauté in the flavorful oil left behind by the linguica, which adds another layer of richness to the broth.
And since the linguica is already wonderfully garlic-forward, the extra fresh garlic in the pot makes the entire kitchen smell amazing while the soup cooks.
Olive Oil and Broth
A generous drizzle of good olive oil helps build the base of this soup and carries the flavor from the sausage through the entire pot. Combined with chicken broth and hot water, it creates a light but flavorful broth that allows the sausage, potatoes, and kale to really shine.
Portuguese Kale Soup
Ingredients
- ⅓ cup extra virgin olive oil
- 1 pound linguica smoked sausage sliced
- 1 medium onion chopped
- 4 cloves garlic minced
- 4 large Yukon Gold potatoes peeled or unpeeled and cut into bite-sized pieces
- 1 teaspoon sea salt
- ½ teaspoon crushed red pepper
- 4 cups unsalted chicken broth
- 4 cups hot water
- 1 pound kale chopped into 2-inch pieces
- 2 cans cannellini beans drained and rinsed
- ½ cup parsley chopped (optional)
- Additional sea salt and black pepper to taste
Instructions
- Slice the linguica into bite-sized pieces.
- Prep the onions and garlic and set aside.
- Cut the potatoes into bite-sized chunks and set aside.
- Coat the bottom of a six-quart sauté pan or Dutch oven with olive oil. Add the linguica to the warmed oil and sauté for about three minutes over medium-high heat.
- Remove the sausage to a bowl and set aside.
- Add the onions and garlic to the linguica-flavored oil. Sauté over medium heat for about five minutes until the onions are soft and translucent.
- Add the potatoes, chicken broth, salt, and crushed red pepper. Bring the mixture to a boil, then reduce heat to low and simmer for about ten minutes.
- Remove 1 cup of potatoes and 1 cup of broth from the pot and place them in a food processor. Purée for about 15 seconds until smooth. Set aside. This will naturally thicken the soup.
- Add the four cups of hot water to the pot and bring it back to a boil.
- Add about half of the chopped kale to the pot and stir it down. As the kale softens and collapses, continue adding the remaining kale until it all fits in the pot.
- Stir in the puréed potato mixture and return the cooked linguica to the soup.
- Simmer on low heat for about 15 minutes.
- Stir in the cannellini beans during the last few minutes of cooking, just long enough to heat them through.
- Add chopped parsley if using.
- Taste the soup before adding additional salt or pepper. The linguica already brings plenty of flavor, so you may not need much more.
- Serve hot with a nice piece of crusty bread.
Notes
This Portuguese Kale Soup is one of those recipes that just gets better with time. The flavors deepen overnight, the broth becomes even richer, and somehow the next bowl tastes better than the first.
Make a big pot, grab a loaf of crusty bread, and enjoy a cozy bowl today … and tomorrow … and maybe even the day after that.
Because if you ask me, a pot of soup on the stove is always a good idea!
