Components

Base

potatoesessentialPeeled and cubed; provide body and starch to the soup.

Protein

fresh Atlantic salmon (skinless, boneless)essentialAdded in chunks, either poached in the broth or gently simmered to retain tenderness.

Aromatics

leek (white and light‑green parts)essentialSautéed in butter to develop a sweet, mellow flavor.

fresh dillessentialAdded near the end to preserve bright, herbal aroma.

Fat

butteressentialUsed for cooking the leek and enriching the overall texture.

Acid

lemon juice (optional)optionalA small squeeze can brighten the broth.

Liquid

milk or creamessentialCreates the creamy broth base; whole milk or a blend of milk and cream are typical.

Seasoning

white pepperoptionalProvides a subtle hint of heat.

Garnish

fresh dill sprigsoptionalUsed for visual appeal and extra aroma.

Technique

Sautéing leek in butter
Develops a sweet, aromatic foundation without browning that would alter the soup’s color.
Simmering potatoes in dairy liquid
Releases starch to thicken the broth naturally while cooking the potatoes through.
Gentle poaching of salmon
Keeps the fish tender and flaky; overcooking makes it dry and crumbly.
Adding dill at the end
Preserves its fresh, vibrant flavor which would dissipate with prolonged heat.
Tempering dairy before adding to hot liquid
Prevents the milk from curdling when introduced to the hot broth.

  • Swedish Laxsoppa · Sweden

    Often uses a light fish stock in addition to milk and may add carrots.

    Similar ingredient list but sometimes includes a hint of caraway.

  • Salmon and shrimp soup · Finnish coastal region

    Adds peeled shrimp for extra umami and texture.

Related dishes

  • ancestor Fish soup (Nordic)

    The broader tradition of Nordic fish soups provides the conceptual foundation for Lohikeitto.

  • sibling Kalakukko (Finnish fish pie)

    Shares the use of fish and rye but is a baked, pastry‑enclosed dish rather than a soup.

  • descendant Salmon chowder

    Adopts the creamy broth and salmon but adds more vegetables and often a flour thickening.

  • pairs-with Rye bread

    Traditional accompaniment used to soak up the broth and complement the fish.

Substitutions

  • fresh salmon → smoked salmoninadmissible

    Produces a completely different flavor and texture; not a safe substitution for classic Lohikeitto.

  • cream or milk → coconut milkadmissible

    Provides dairy‑free creaminess while preserving the soup’s body; flavor changes but acceptable.

  • potatoes → sweet potatoesadmissible

    Alters the flavor slightly; still yields a creamy soup, considered a safe variation.

  • leek → onionadmissible

    Onion provides similar aromatic base; safe substitution if leek is unavailable.

  • butter → olive oiladmissible

    Makes the dish dairy‑free but reduces richness; safe for dietary needs.

  • dill → parsleyinadmissible

    Loses the characteristic Finnish dill note; not recommended for authentic flavor.

Common mistakes

  • Overcooking the salmon, causing it to become dry and crumbly.
  • Adding cold dairy directly to the hot broth, leading to curdling.
  • Skipping the sauté step for leeks, resulting in a weaker flavor foundation.
  • Adding dill too early, which dissipates its fresh aroma.
  • Using smoked salmon instead of fresh, altering the dish’s identity.

Provenance

Lohikeitto has been a staple of Finnish rural and coastal kitchens since at least the 19th century, appearing in early Finnish home‑economics manuals and cookbooks. Its development reflects the abundance of fresh Atlantic salmon in Finnish waters combined with the northern European tradition of using dairy as a thickening and enriching agent. While similar cream‑based fish soups exist in neighboring Baltic and Scandinavian cuisines, the precise combination of fresh salmon, potatoes, leek and dill is recognized as distinctly Finnish.
