What is Icelandic Fish Soup?

Icelandic Fish Soup, also known locally as “Fiskisúpa,” is a creamy, rich, and aromatic fish chowder that holds a beloved place in Icelandic cuisine. Traditionally made with the day’s catch—usually cod, haddock, or halibut—it’s a practical dish born from necessity and refined with layers of flavor. Think of it like New England clam chowder’s minimalist, Nordic cousin. It doesn’t try too hard—there’s no need for overly fancy ingredients or elaborate techniques.

Instead, it leans on buttery sautéed vegetables like leeks and celery, a hint of curry for warmth, and a touch of tomato paste to deepen the broth. The key is letting the fish shine. And if you’re picturing this soup simmering away in a seaside Icelandic cottage kitchen, you’re not far off. What sets it apart is that dollop of whipped cream swirled on top just before serving—yes, whipped cream!—which melts into the broth and gives it that signature luscious finish. It’s hearty without being heavy, and it’s definitely more than just “fish soup.”

Reasons to Try Icelandic Fish Soup

First of all, Icelandic Fish Soup is dinner hero material. It’s quick, filling, and has that magical quality of feeling luxurious without making your kitchen look like a tornado hit it. The ingredient list is mostly staples—onion, celery, leeks, potatoes—and you can swap in whatever white fish you’ve got. That kind of flexibility makes it both accessible and budget-friendly. But let’s talk flavor. The mellow curry spice mingling with the cream and fish is like a warm sweater for your taste buds. It’s cozy, a little unexpected, and extremely satisfying.

And unlike some heavier chowders, this one doesn’t sit like a rock in your stomach. It’s rich but clean, thanks to a light chicken stock base. Bonus? If you’ve got kids, this soup usually flies under the radar of suspicion—they just think it’s creamy and tasty. And if you’re looking for more warm, soothing recipes that don’t require a culinary degree, you might also love our Creamy Roasted Jerusalem Artichoke Soup or the Soup Dumplings in Creamy Gochujang Sauce. Because let’s face it—comfort food should be easy to love and easier to make.

Ingredients Needed to Make Icelandic Fish Soup

• 1.5 lbs halibut or other white fish like cod or striped bass
• 2 tbsp butter
• 1 tbsp olive oil
• 1 leek, about 1 cup sliced
• 3 stalks celery, about 1/2 cup diced
• 1 medium onion, about 1.5 cups diced
• 1 tsp salt
• 1/2 tsp curry powder
• 2 tbsp tomato paste
• 32 ounces chicken stock
• 3/4 lb potatoes (about 4 small Yukon golds), cut into 1″ chunks
• 1 cup heavy cream
• 1/4 cup heavy cream, whipped (optional)
  Garnish
• 1 tbsp chopped chives
• Celery leaves

Instructions to Make Icelandic Fish Soup – Step by Step

Step 1: Sauté the Aromatics

Start by grabbing a large stock pot and placing it over medium heat. Melt the butter and olive oil together until they start to bubble—this combo gives your soup a silky richness that olive oil alone just can’t match. Toss in the sliced leeks, diced celery, and chopped onion. Let those simmer and sizzle for about 7 minutes, stirring occasionally. You’re looking for them to turn soft and translucent, not browned. This is where the base of your soup’s flavor is born, and it smells amazing—like the beginning of something good.

Step 2: Build the Flavor

Once your veggies have softened, it’s time to layer in the magic. Add 1 teaspoon of salt, 1/2 teaspoon of curry powder, and 2 tablespoons of tomato paste. Stir it all together and let it cook for another 2 minutes, just until everything is fragrant and the tomato paste starts to darken slightly. This little step deepens the flavor and gives the broth its signature golden-orange hue. Don’t skip it—it’s what makes this more than just “fish in broth.”

Step 3: Simmer with the Stock and Potatoes

Pour in the 32 ounces of chicken stock and bring the pot to a gentle boil. Add your diced Yukon gold potatoes and reduce the heat to a simmer. Let everything cook together for 15 to 25 minutes, depending on how large your potato chunks are. You want them fork-tender but not falling apart. If you’re multitasking (aka wrangling toddlers or answering emails), set a timer. This simmer time is hands-off and gives you a breather—or a chance to throw together a Southern Potato Salad for tomorrow’s lunch.

Step 4: Whip the Cream Garnish

While the potatoes are doing their thing, whip 1/4 cup of heavy cream using a hand mixer or a whisk if you’re feeling ambitious. Beat it just until soft peaks form—not stiff like dessert whipped cream. This little topping might sound unusual, but trust the process. Icelandic Fish Soup is all about contrasting textures, and this airy cream melts into the hot broth in the most luxurious way.

Step 5: Add the Fish Gently

Now, gently nestle your fish pieces into the soup. Whether you’re using halibut, cod, or striped bass, make sure it’s cut into large chunks so it doesn’t fall apart. Cook for 2 to 4 minutes—yes, that’s it! The fish should be opaque and flake easily. Overcooking it is basically a crime in this dish. If you’re feeling adventurous, you can even use shrimp or scallops instead, just like they do in Iceland. Or go wild and let the hot broth finish off some raw lobster tails—no extra cooking required.

Step 6: Swirl in the Cream

Turn off the heat and slowly pour in 1 cup of heavy cream, stirring gently as you go. The soup will turn creamy and rich without becoming overly thick. This step gives Icelandic Fish Soup its classic silky texture and comforting mouthfeel. Don’t rush it—pour slowly and enjoy watching your soup go from brothy to beautiful.

Step 7: Garnish and Serve

Ladle the soup into bowls and top each with a spoonful of your homemade whipped cream. Sprinkle chopped chives and celery leaves on top for a pop of color and a bit of fresh flavor. Serve it hot with a chunk of crusty bread or even a light salad like our Lemon Capellini Salad on the side for contrast. And then—dig in. You’ve earned this.

What to Serve with Icelandic Fish Soup

Icelandic Fish Soup is rich enough to stand alone but plays well with sides. A warm, crusty sourdough or rustic rye bread is perfect for dipping into the creamy broth. Want something a little lighter? A tangy salad like our Honeycrisp Apple Broccoli Salad balances the richness with crunch and brightness. For an extra comforting dinner, pair with Creamy Pistachio Cake or the Butter Pecan Praline Poke Cake for dessert. Yes, you deserve it.

Key Tips for Making Icelandic Fish Soup

Use a thick cut of fish like halibut or cod—thinner fillets tend to fall apart in the broth. Dice your potatoes into even chunks so they cook uniformly, and don’t skip sautéing the vegetables; that’s where your soup’s depth comes from. The curry powder may feel like a wild card, but it adds warmth without making the dish spicy. And that whipped cream? Try it once. It’s the kind of “why didn’t I do this sooner?” detail. Bonus tip: this soup tastes even better the next day after the flavors have time to mingle. Just reheat gently and enjoy.

Storage and Reheating Tips Icelandic Fish Soup

Got leftovers? Lucky you. Store any remaining Icelandic Fish Soup in an airtight container in the fridge for up to 3 days. Reheat it gently on the stovetop over medium-low heat to avoid overcooking the fish or separating the cream. If it thickens too much, add a splash of chicken stock or water to loosen it. Avoid freezing—the cream can split, and the potatoes go mushy. Trust me, it’s worth enjoying fresh. If you’re into meal planning, this soup makes a fantastic next-day lunch with some Italian Grinder Pasta Salad or even a Lemon Basil Pasta Salad.

FAQs

Can I make Icelandic Fish Soup dairy-free?
Sure thing! Swap the heavy cream for full-fat coconut milk or an unsweetened cashew cream alternative. It won’t taste exactly the same, but it’ll still be cozy and creamy.

What’s the best fish for this soup?
Halibut’s the gold standard, but cod, haddock, or even striped bass work beautifully. Just go for a firm white fish that holds up to gentle simmering.

Can I use seafood instead of fish?
Absolutely. Shrimp, scallops, or even chunks of lobster make delicious stand-ins. In Iceland, it’s common to cook the seafood directly in the broth without extra heat.

Is this soup freezer-friendly?
Unfortunately, not really. The cream and potatoes don’t love the freezer, and thawing can leave you with a separated, grainy texture. Stick to fresh, or plan for tasty leftovers within a few days.

Does it taste fishy?
Not at all! It’s mild, creamy, and comforting—perfect for folks who say they “don’t like fish.” This might just change their mind.
