Cooking Traditional Finnish Soups Lohikeitto Kalakeitto and Perfect Seasoning Tips

A good Finnish soup does not try to impress with complicated steps. It wins with clean broth, tender potatoes, fresh fish, a handful of herbs, and seasoning that knows when to stop.

That simplicity is what makes soups like lohikeitto, the beloved creamy salmon soup, and kalakeitto, a classic fish soup, so satisfying. They are practical, warming dishes built for cold weather, busy kitchens, and ingredients close to home. For home cooks, they are also forgiving. Once the potatoes are soft and the fish is just cooked, dinner is nearly done.

Finnish soups often use humble ingredients, but the flavor depends on timing, freshness, and balance. Dill should taste bright, not dull. Fish should stay moist. Cream should soften the broth without covering up the salmon or whitefish. Salt should bring everything forward, not make the soup taste salty.

If you want to Learn how to cook and season soups from Finland, start with these two classics and the small habits that make them taste truly comforting.

Lohikeitto is simple, creamy, and built around fresh salmon and dill.

Why Finnish soups taste clean, hearty, and comforting

Traditional Finnish soups are shaped by the northern climate and by ingredients that store well or come from nearby waters, fields, and forests. Potatoes, carrots, onions, leeks, rutabaga, fish, cream, herbs, and rye bread all fit naturally into the Finnish kitchen.

The flavors tend to be gentle rather than spicy. Finnish soup seasoning often leans on:

• Dill

• Allspice

• White pepper

• Bay leaf

• Parsley

• Chives

• Salt

• Butter

• Cream

  
  

That does not mean the soups are bland. The best versions taste layered. A little butter gives the vegetables sweetness. Fish bones or skin can strengthen the broth. Dill adds a fresh, green lift at the end. Cream rounds the edges. White pepper adds warmth without changing the character of the soup.

Fresh herbs and local produce matter because there are so few places to hide. If the potatoes are waxy and flavorful, the soup tastes better. If the dill is fresh, the whole pot wakes up. If the fish is high quality, the broth feels clean instead of heavy.

For a Finnish-style meal, serve soup with rye bread, butter, and a simple cucumber or beet salad. The bread is not an afterthought. It makes the soup feel complete.

Lohikeitto brings salmon, cream, potatoes, and dill together

Lohikeitto is the Finnish salmon soup many people fall in love with first. It is creamy but not thick like chowder. The texture should stay brothy enough to spoon easily, with chunks of salmon, tender potatoes, and sweet vegetables.

Essential ingredients for lohikeitto

A classic pot of lohikeitto needs only a short list:

Ingredient	What it does in the soup
Salmon	Adds rich flavor and soft texture
Potatoes	Make the soup hearty and filling
Leek or onion	Builds sweetness in the base
Carrot	Adds color and gentle sweetness
Fish stock or water	Forms the broth
Cream	Makes the soup smooth and rich
Dill	Gives the soup its signature freshness
Butter	Adds depth to the vegetables
White pepper	Brings quiet warmth
Salt	Sharpens every flavor

Skin-on salmon works especially well if the fish is fresh. You can simmer the skin briefly in the broth for extra flavor, then remove it before serving. If using skinless fillets, choose pieces that look moist and smell clean, never strongly fishy.

For the potatoes, use waxy or all-purpose potatoes. They hold their shape better than very starchy potatoes. Yukon Gold potatoes are a good choice in many U.S. kitchens because they become tender without falling apart too quickly.

A simple lohikeitto method

Start by melting butter in a soup pot. Add sliced leek or onion and cook until soft, not browned. Add diced carrots and potatoes, then pour in fish stock or water. Add a bay leaf if using, plus a small pinch of white pepper.

Simmer until the potatoes are almost tender. This is the key moment. If the potatoes are fully cooked before the salmon goes in, the fish can cook gently without waiting too long.

Cut salmon into large bite-size pieces. Add it to the pot and simmer very gently. Do not boil hard. Salmon cooks quickly, and rough boiling can make it dry or cause it to break into flakes.

Once the salmon turns opaque, stir in cream. Warm the soup through, then turn off the heat. Add chopped fresh dill right before serving.

The best lohikeitto tastes softly rich, with the dill and salmon still clear and fresh.

Seasoning tips for lohikeitto

Season lohikeitto in stages. Add some salt when the potatoes go in, then adjust near the end. Fish stock can vary in saltiness, so final seasoning matters.

Use white pepper with a light hand. It should be noticeable only as warmth in the background. Black pepper is acceptable if that is what you have, but white pepper gives a more traditional Finnish feel.

Add dill late. If dill boils for too long, it loses its fresh aroma and turns dull. Stir most of it in at the end and save a little for the bowls.

A small pat of butter added off the heat can make the soup taste richer without adding more cream. This is useful if the broth tastes good but needs a little softness.

Kalakeitto shows how simple fish soup can be deeply flavorful

Kalakeitto means fish soup, and it can take many forms. Some versions are clear and light. Others use milk or cream. The fish might be perch, pike, whitefish, cod, pollock, or another mild fish. The idea is flexible, which makes kalakeitto a useful recipe for home cooks.

Where lohikeitto centers on salmon and cream, kalakeitto often feels more rustic. It is a smart way to use seasonal fish and common vegetables. The result should taste fresh, mild, and warming.

Kalakeitto can be light and brothy or enriched with milk or cream.

Essential ingredients for kalakeitto

A basic kalakeitto usually includes:

• Mild white fish, cut into pieces

• Potatoes, peeled or scrubbed and diced

• Onion, leek, or both

• Carrots or other root vegetables

• Fish stock, vegetable stock, or water

• Bay leaf and allspice berries

• Fresh dill, parsley, or chives

• Salt and white pepper

• Milk or cream, if making a creamy version

  
  

Allspice is one of the seasonings that gives Finnish fish soup its distinct character. Use whole berries if possible. They add warmth and a faint sweetness without making the soup taste like baking spices. Remove them before serving if you can, or tie them in a small piece of cheesecloth.

A simple kalakeitto method

Cook onion or leek in butter until soft. Add potatoes, carrots, stock, bay leaf, a few allspice berries, salt, and white pepper. Simmer until the vegetables are tender.

Add the fish near the end. This is the same rule as lohikeitto, but it matters even more with lean white fish. Cod, pollock, and similar fish can dry out if boiled for too long.

For a clear kalakeitto, stop there and finish with fresh herbs. For a creamy version, lower the heat and add milk or cream once the fish is nearly cooked. Warm gently.

If using milk, avoid a hard boil after adding it. Milk can separate if overheated. Cream is more stable, but it still tastes better when treated gently.

Clear, milky, and creamy versions

Kalakeitto has room for personal style. A clear broth version tastes light and clean, especially with fresh dill and parsley. A milk-based version feels traditional and homely. A cream version is richer and closer in spirit to lohikeitto.

Version	Best for	Seasoning approach
Clear kalakeitto	Fresh mild fish and lighter meals	Dill, parsley, bay leaf, allspice, white pepper
Milk kalakeitto	Everyday comfort food	Gentle salt, white pepper, onion, dill
Creamy kalakeitto	Cold weather and richer dinners	Butter, cream, dill, restrained allspice

If the soup tastes flat, it may not need more herbs first. It may need more salt. Add a little, stir, wait a minute, and taste again. If it tastes rich but heavy, add more fresh dill or parsley at the end.

Seasoning Finnish soups is about restraint and freshness

Finnish soup seasoning rewards patience. Instead of adding many spices, choose a few and let them do their work.

Use dill like a main ingredient

Dill is central to Finnish fish soups. It pairs naturally with salmon, white fish, potatoes, and cream. Use the tender fronds, chopped shortly before serving.

For the best flavor:

• Add stems to the simmering broth if they are clean and fresh

• Add chopped fronds at the end

• Sprinkle more dill over each bowl

• Avoid dried dill unless fresh is not available

  
  

Dried dill can help in a pinch, but it will not give the same bright finish.

Let allspice stay in the background

Allspice appears in many Nordic kitchens, often in savory dishes. In fish soup, whole allspice berries add depth. Use only a few. The flavor should sit behind the fish and vegetables.

If using ground allspice, use a tiny pinch. It can take over quickly.

Choose local produce when possible

Finnish soup traditions come from cooking with what is nearby and in season. That idea works anywhere. Use the best local potatoes, carrots, onions, herbs, and fish available.

In the U.S., that might mean:

• Yukon Gold potatoes from a farm stand

• Local carrots in fall or winter

• Fresh dill from a garden or market

• Sustainable salmon or white fish from a trusted fishmonger

• Leeks when they look firm and fresh

  
  

Local produce often has better texture and a cleaner flavor. Since Finnish soups use simple ingredients, that difference shows.

Build flavor before adding liquid

Do not rush the first step. Cooking onion, leek, or carrot in butter gives the soup a sweeter, fuller base. Keep the heat moderate. Browning is not the goal. Softness is.

Once the broth goes in, simmer gently. Finnish fish soups should not feel aggressive. A quiet simmer keeps vegetables intact and helps the broth stay clear and pleasant.

Finish with balance

Before serving, taste for four things:

Salt

The soup should taste rounded, not sharp or dull.

Freshness

Dill, parsley, or chives should lift the bowl.

Richness

Cream, milk, or butter should support the broth.

Fish texture

The fish should be just cooked and tender.

If the soup tastes too rich, add herbs. If it tastes thin, simmer the vegetables a little longer next time or start with better stock. If the fish tastes dry, add it later and lower the heat.

Practical tips for making Finnish soups at home

These soups fit weeknight cooking, but small choices make them better.

Cut potatoes and carrots into similar sizes so they cook evenly. Keep fish pieces larger than the vegetables because they cook fast and can break apart. Stir gently after adding fish.

Use fish stock if you have it. If not, water can work, especially with salmon, butter, vegetables, and herbs. A light vegetable stock is another option, but avoid strongly flavored broths that cover the fish.

If making soup ahead, cook the base first and add the fish when reheating. This keeps the fish tender. Creamy soups can be reheated gently on the stove. Avoid boiling them after the cream or milk has been added.

Serve Finnish soups simply. A bowl of lohikeitto or kalakeitto with rye bread and butter is enough. Pickled cucumbers, beet salad, or a crisp green salad can add contrast.

Leftovers keep best if cooled quickly and stored in the refrigerator. Reheat gently and add a little fresh dill before serving. The herbs make the soup taste new again.

Frequently Asked Questions

Can I make lohikeitto without fish stock?

Yes. Water works if the salmon is fresh and you build flavor with butter, leek or onion, potatoes, carrots, salt, and dill. Fish stock adds depth, but it is not required.

What fish works best for kalakeitto?

Mild white fish such as cod, pollock, perch, pike, or whitefish works well. Choose fresh fish with a clean smell and firm texture. Avoid fish that falls apart too easily.

Can I use frozen fish in Finnish soup?

Yes. Thaw it safely in the refrigerator, pat it dry, and add it near the end of cooking. Frozen fish can release extra liquid, so taste and adjust the salt before serving.

Is lohikeitto supposed to be thick?

No. Lohikeitto is creamy, but it is usually more like a brothy soup than a thick chowder. The potatoes add body, while the cream gives smoothness.

What herbs are most traditional for Finnish fish soups?

Dill is the classic choice, especially with salmon. Parsley and chives also work well. Add fresh herbs at the end so they stay bright and fragrant.

Bring Finnish comfort to the table

Lohikeitto and kalakeitto prove that simple soup can feel special. The method is easy to learn: soften vegetables in butter, simmer potatoes until tender, add fish late, season with care, and finish with fresh herbs.

Start with lohikeitto if you want something creamy and familiar. Try kalakeitto when you have good white fish and want a lighter bowl. Keep the seasoning calm, use fresh dill generously, and let local produce do its work.

A pot of Finnish soup does not ask for much. It asks for good ingredients, gentle heat, and a final handful of herbs. That is more than enough for a comforting meal at home.
