Soups & Stews
This Punahou Portuguese bean soup recipe brings together two cultures in a single pot—Hawaiian comfort meets Portuguese tradition. The slow simmer transforms simple ingredients into a rich, smoky broth with tender beans and aromatic herbs, a dish that's as hearty as it is historic.
I've adapted the classic caldo verde flavors to include local touches like kala seaweed for depth, creating a soup that feels both nostalgic and fresh. The key lies in the layers of flavor: smoky paprika, garlic-infused oil, and a touch of vinegar to brighten the richness.
The recipe begins with soaking beans overnight for maximum tenderness, then builds flavor through a careful balance of sautéed onions, garlic, and smoked paprika. A splash of white wine deglazes the pot, while fresh herbs and a hint of vinegar create the signature Portuguese tang.
What makes this version special is the incorporation of Hawaiian ingredients—kala seaweed adds umami, while lilikoi (passion fruit) offers a tropical brightness that bridges the two cultures beautifully.
By the time it's done, you'll have a soup that's deeply satisfying and full of complex flavors—smoky, savory, and subtly sweet all at once. The texture is perfect: creamy from the beans and potatoes, with just enough bite from the kale and seaweed.
This isn't just a meal; it's a celebration of heritage, adaptability, and the kind of comfort food that brings people together.
Serve it with crusty bread to soak up every last drop of that flavorful broth, or pair it with a simple green salad for balance. The leftovers reheat beautifully, making it ideal for meal prep or feeding a crowd. Let's get cooking—this soup is worth every minute of simmering time.
Ingredients for punahou portuguese bean soup
Sixteen ingredients blend Portuguese tradition with Hawaiian flavors for a deeply satisfying bean soup.
| Ingredient | Amount | Notes |
|---|---|---|
| Dried White Beans 🌱 | 2 cups | Soaked overnight for tenderness |
| Russet Potatoes 🥔 | 2 medium | Peeled and cubed evenly |
| Yellow Onions 🧅 | 2 large | Diced for even cooking |
| Garlic Cloves 🧄 | 6 cloves | Minced for infused oil |
| Smoked Paprika 🌶️ | 2 tbsp | For signature smoky depth |
| Dried Kale 🥬 | 4 cups | Chopped for hearty texture |
| Kala Seaweed 🌊 | 1 package | Dried, rehydrated for umami |
| Extra-Virgin Olive Oil 🫒 | ½ cup | For garlic infusion |
| Dry White Wine 🍷 | 1 cup | Deglazes the pot beautifully |
| Lilikoi (Passion Fruit) Puree 🍈 | ¼ cup | Fresh or bottled for brightness |
| White Vinegar 💧 | 1 tbsp | Balances richness perfectly |

The dried white beans form the heart of this soup—Great Northern or cannellini work best for their creamy texture. Soak them overnight in plenty of water (at least 8 cups) to ensure they're tender but not mushy. Trader Joe's carries pre-soaked beans in a bag if you're short on time, though they cost a bit more. The potatoes should be Russet or Yukon Gold—their waxy texture holds up better to long simmering. For the kala seaweed, Asian markets often carry it dried in small packages; if unavailable, dried dulse flakes work as a substitute. The smoked paprika is non-negotiable—it's what gives this soup its signature depth. Penzeys carries an excellent variety if you want to splurge.
No white wine? Substitute with extra vegetable broth—just add a splash of vinegar to mimic the acidity. Fresh thyme is ideal, but dried works at one-third the amount (that's why the recipe calls for half a cup fresh). Short on lilikoi? Passion fruit concentrate or even a splash of lime juice can bridge the gap. The kale can be swapped for collard greens or spinach, though kale's slightly bitter edge complements the richness. For the garlic, roast it first for a sweeter, deeper flavor—toss minced cloves on a baking sheet at 400°F for 10 minutes before adding to the oil. The kala seaweed needs rehydrating: soak it in warm water for 10 minutes before adding to the pot.
This soup tastes even better the next day as flavors meld—double the batch and freeze half for future meals. Store leftovers in the fridge for up to 5 days, or freeze for 3 months. To reheat, add a splash of water or broth to prevent thickening. The garlic-infused oil keeps in the fridge for 1 week if stored in a sealed jar. For meal prep, I like to portion the broth separately from the beans and potatoes—reheat the broth first, then add the solids to warm through. The kala seaweed loses potency after freezing, so use it fresh if possible.
Why You'll Love This Recipe
- Few Ingredients, Big Payoff: I swear by this recipe because it’s that simple—just beans, potatoes, onions, garlic, and a pinch of smoked paprika. No fancy prep, no last-minute grocery runs. The dried beans soak overnight, but honestly? That’s the only step that isn’t active. The rest is dump-and-simmer while you do actual things.
- Smoky Depth in Minutes: That smoked paprika? It’s the secret weapon. A single teaspoon transforms this into something rich and earthy, like a hug in a bowl. The potatoes absorb the flavor until they’re tender and infused—crisp edges, creamy middle, and a warmth that lingers. (Yes, even on a Tuesday night.)
- Leftovers That Don’t Suck: Between us, most soups turn into sad, watery meals by day three. Not this one. The beans thicken as it sits, the potatoes stay sturdy, and the flavor deepens. I’ve reheated this for four days straight—still hearty, still satisfying. Perfect for meal prep or when you’re too tired to cook.
- Budget-Friendly Crowd-Pleaser: Dried beans and russets are cheap, but this soup feels special. It feeds six for under $10, and everyone—picky eaters included—asks for seconds. My roommates used to mock my “weird Portuguese soup,” but now they beg for it. (They’ve since learned to pronounce it right.)
Step-by-step instructions for Punahou Portuguese bean soup
This traditional recipe delivers deep, smoky flavors through slow simmering and careful layering of ingredients.
Prepare the Beans and Aromatics
Begin by draining the soaked 2 cups dried white beans and rinsing them thoroughly under cold water. Place them in a large stockpot and cover with fresh water by about 2 inches. Add 1.5 teaspoons salt and bring to a boil over medium-high heat. Once boiling, reduce heat to medium-low and simmer for 30 minutes, stirring occasionally to prevent sticking.
While the beans cook, peel and cube the 2 medium russet potatoes into ½-inch pieces. Dice the 2 large yellow onions into ¼-inch pieces and mince the 6 cloves garlic. Heat 0.5 cup extra-virgin olive oil in a separate skillet over medium heat. Add the onions and cook for 5 minutes until softened. Add the garlic and 2 tablespoons smoked paprika, stirring constantly for 1 minute until fragrant. This aromatic base forms the soul of the soup.
Build the Soup Foundation
Add the potato cubes, onion-garlic mixture, and 1 package kala seaweed (rehydrated according to package instructions) to the simmering beans. Stir gently to combine, then pour in the 1 cup dry white wine. The wine will deglaze the pot, releasing any browned bits and infusing the soup with brightness. Simmer uncovered for 45 minutes, stirring occasionally, until the potatoes are fork-tender and the beans are nearly tender.
Here's where the magic happens: add the 0.25 cup lilikoi (passion fruit) puree and 1 tablespoon white vinegar. The tangy-sweet lilikoi balances the richness while the vinegar brightens the flavors. Stir well and continue simmering for another 20 minutes. The soup should now have a thick, velvety consistency with visible chunks of beans and potatoes.
Finish with Greens and Herbs
Chop the 4 cups dried kale into ½-inch strips and add them to the pot. Stir gently to distribute evenly. Sprinkle in the 0.5 cup fresh thyme leaves and 1 teaspoon freshly cracked black peppercorns. Simmer uncovered for 15-20 minutes until the kale is tender but still vibrant. The thyme will release its earthy aroma, while the peppercorns add subtle warmth.
Taste and adjust seasoning with additional salt if needed. The soup should be rich but not overly salty, with a harmonious balance of smoky, tangy, and herbal notes. Real talk: if the soup seems too thick after adding the kale, whisk in ¼ cup hot water to reach your desired consistency.
Rest and Serve
Remove the pot from heat and let the soup rest for 10 minutes. This resting period allows the flavors to meld and the beans to fully absorb the surrounding liquid. Ladle the soup into bowls, ensuring each serving contains a generous portion of beans, potatoes, and greens. Garnish with an additional sprinkle of fresh thyme leaves and a drizzle of extra-virgin olive oil for extra richness.
Serve immediately while hot. The contrast of the smoky paprika, bright lilikoi, and hearty greens creates a symphony of textures and flavors. Each spoonful should deliver tender beans, creamy potatoes, and a vibrant broth that coats the palate. This soup tastes even better the next day, so consider making extra for leftovers.
Pro Tips For Making Punahou Portuguese Bean Soup
- SOAK BEANS 12 HOURS: I learned this the hard way—rushing the soak with dried white beans leaves them tough and gummy. Use a big pot, cover them with cold water by 2 inches, and let them sit overnight. The longer they soak, the creamier your soup will be, and you’ll skip the long simmering time later.
- PEEL POTATOES AFTER COOKING: Russet potatoes hold their shape better if you peel them after boiling them for 5 minutes. Toss them in cold water first, then peel—no more slipping around the cutting board. This keeps the starch intact for a thicker, heartier soup.
- TOAST THE PAPRIKA: Smoked paprika loses its depth if you just sprinkle it in. Dry-toast it in a small pan over medium heat for 30 seconds until fragrant—it deepens the flavor without bitterness. Stir it into the onions early so it blooms into the broth.
- STIR THE POTATOES: I used to let the potatoes sit at the bottom like lazy potatoes. Instead, give them a stir every 5 minutes after they’ve been in the pot for 15 minutes—this prevents them from turning mushy and ensures even cooking. A wooden spoon works best.

Frequently asked questions
Why does this recipe use kala seaweed instead of traditional Portuguese ingredients?
Kala seaweed adds a unique umami depth that bridges Portuguese and Hawaiian flavors. Traditional Portuguese soups like caldo verde use chouriço or chorizo, but kala provides a local, sustainable alternative that enhances the broth's complexity without overpowering the dish. It's a perfect example of how this recipe honors both cultures.
Can I substitute canned beans for dried beans to save time?
Yes! Use 1 (15 oz) can white beans, drained and rinsed, instead of dried. Reduce the simmering time to 45 minutes total and add the kale and thyme only in the final 10 minutes. The texture will be slightly softer, but the flavor remains rich and satisfying.
What's the best way to store leftovers?
Store leftovers in an airtight container in the fridge for up to 5 days or freeze for 3 months. To reheat, add a splash of water or broth to prevent thickening. The kala seaweed loses potency after freezing, so use it fresh if possible for the best flavor.
How can I make this soup spicier?
Add 1 tbsp gochujang or 1-2 slices fresh chili pepper when sautéing the onions. For balance, include an extra ½ tsp sugar to soften the heat. Garnish with crispy fried shallots for crunch and contrast.
What's the secret to getting the perfect smoky flavor?
The key is using high-quality smoked paprika and letting it cook for 1 minute in the garlic-infused oil until fragrant. For extra depth, toast the paprika in a dry skillet for 30 seconds before adding it to the onions. This enhances the smoky aroma without bitterness.
