Caldo Verde (Green [Kale] Soup)
- Jul 8
- 4 min read
Some recipes don't need reinventing. Caldo Verde is one of them.
It's one of Portugal's most iconic dishes, and for good reason. With just a handful of humble ingredients, it somehow manages to become greater than the sum of its parts. Creamy potatoes. Sweet onions. Peppery olive oil. Smoky chouriço. And those impossibly thin ribbons of kale floating through every spoonful.
Simple? Absolutely. Boring? Not even close. There's a reason it's been around for centuries. Some recipes come and go. Caldo Verde sticks around.

Why You'll Love This Recipe
One pot.
Surprisingly inexpensive.
Authentic Portuguese comfort food.
Even better the next day.
Perfect year-round, even though everyone thinks it's only a winter soup.
Ingredients
2 pounds Agria potatoes, peeled and diced (900g)
Substitution: Yukon Golds make for a naturally creamier soup, so I'd avoid russets if possible.
1 large onion, diced
3 garlic cloves, minced
3 tablespoons extra virgin olive oil (45ml)
6¾ cups chicken stock (1.6L)
Vegetarian Option: Use vegetable stock.
8 ounces Portuguese chouriço (225g), sliced
Substitution: Portuguese linguiça is an excellent alternative.
5 ounces Portuguese couve-galega (140g), cut into paper-thin ribbons
Substitution: Lacinato (Tuscan) kale is my first choice. But we work with what we've got! And what we have in the US (that works better than US kale) is collard greens.
Salt and freshly ground black pepper, to taste
To Finish
A generous drizzle of excellent Portuguese extra virgin olive oil
Instructions
Step 1: Build the Base
Heat the olive oil in a large Dutch oven over medium heat.
Add the onion and cook until softened, about 6 to 8 minutes. Add the garlic and cook for another minute.
Your kitchen should already be starting to smell like Portugal.
Step 2: Add the Potatoes
Add the diced potatoes and pour in the stock. Bring everything to a boil before reducing the heat to a gentle simmer.
Cook for about 20 minutes, or until the potatoes are completely tender.
Step 3: Blend
Using an immersion blender, purée the soup until completely smooth. No immersion blender? Carefully blend it in batches using a countertop blender before returning it to the pot.
This should be silky. Not chunky.
Step 4: Add the Chouriço
Return the soup to a gentle simmer. Add most of the sliced chouriço, reserving a few slices for garnish if you'd like.
Let it simmer for about 10 minutes. The smoky paprika and garlic from the sausage begin flavoring the broth almost immediately.
Step 5: The Kale
Add the kale during the final 5 minutes of cooking. It should soften while still keeping its vibrant green color and just a little bite. If using another type of green, think slightly softer than al dente.
Taste and season with salt and pepper if needed.
Step 6: Serve
Ladle into warm bowls. Top with a few slices of chouriço. Finish with a generous drizzle of good Portuguese olive oil.
Serve immediately with plenty of crusty bread. Because somebody's going to wipe the bowl clean.
Tuga Tip
Slice the kale as thinly as humanly possible. I'm talking ribbons. Not strips. If you think it's thin enough... Slice it one more time.
Those delicate ribbons are one of the signatures of a truly authentic caldo verde.
How We Enjoy It in My Portuguese Casa
There's always bread. Always. Sometimes it's warm pão caseiro. Sometimes it's fresh papo-secos. Either way, somebody's tearing off a piece before the soup even hits the table.
We usually drizzle a little extra olive oil over the top, pile on a few more slices of chouriço than we probably should, and call it dinner. Simple food. Good company. That's really what Portuguese cooking is all about.
Good to Know
Can I make it ahead?
Absolutely.
Like many soups, it's even better the next day.
Can I freeze it?
Yes, but I recommend freezing it before adding the kale. Stir in fresh kale when reheating for the best texture and color.
Do I have to blend it?
For traditional caldo verde, yes. The creamy potato base is one of the defining characteristics of the soup.
Can I make it vegetarian?
Definitely. Swap in vegetable stock and omit the chouriço, or use a good smoked vegetarian sausage. It'll be different, but still delicious.
One Last Bite
Caldo Verde has never tried to impress anyone. It doesn't rely on expensive ingredients or complicated techniques. Instead, it quietly reminds us why Portuguese cooking has endured for generations.
Take a few humble ingredients. Treat them with care. Share them with people you love. And somehow, you've created something far greater than the sum of its parts. That's the magic of this soup.
And around my Portuguese casa, it never lasts long enough for seconds.
