Lohikeitto (Finnish salmon soup)

Updated 21 October 2026

A creamy salmon and potato soup eaten warm as the kitchen's slow follow-up to the löyly. The Finnish pot is kept ready on the stove while the steam is still on the stones, so the body moves straight from bench to bowl without a long cooling gap. Salt from the broth is what the tradition reaches for first, since sweat is just leaving the skin.

Herbs and practices affect people differently — nothing here suits everyone. Take it as reference.

Tonight, try this

Simmer a pot tonight, started about twenty minutes before you step into the sauna. A piece of salmon, a couple of potatoes, a sliced leek, stock to cover, a pour of cream at the end, and a fistful of fresh dill over the top. Ladle it while it is still steaming and eat it before the sweat has fully cooled on the skin.

Ingredients

Salmon fillet, skin off, cut into rough chunks
Floury potatoes, peeled and cubed
A leek or an onion, sliced into thin half-moons
Fish or light chicken stock, enough to cover the vegetables
Cooking cream, or full-fat milk for a lighter bowl
A generous handful of fresh dill, chopped
Salt and a few grinds of white pepper, to taste

How it is made

Sweat the sliced leek or onion in a knob of butter over a quiet heat until it goes soft and sweet.
Pour in the stock and bring the pot up to a low simmer.
Drop in the cubed potatoes and cook until a knife slides through them without resistance.
Slip the salmon pieces into the broth and let them poach just until they flake at the edge.
Stir in the cream, taste the broth, and season with salt and white pepper.
Pull the pot off the heat, scatter a handful of dill over the top, and bring the whole pot to the table for ladling.

When it is made

The kitchen starts the pot while the sauna stove is still warming, so the bowl is ready the moment the löyly ends. In the Finnish reading of the custom the soup is the unhurried second half of the sauna evening: warm, lightly salted, and easy on a stomach that has just been wrung out by heat. The same pot turns up at weekend family gatherings where the wood-fired sauna has been running for an hour or two, and at the lakeside cottage where the bath and the meal are planned as one long evening rather than two separate events. The point is rhythm, not portion — a quiet bowl that lets the body settle without rushing into anything cold or rich.

Disclaimer

At culinary amounts salmon and cream are everyday foods with no well-documented interactions. If you take blood-thinning medication, eating oily fish several times a week is worth a quick mention to a clinician, since the deep-sea variety carries more than lean river fish. After a long hot sauna, sip plain water alongside the bowl — the soup is hearty and warming rather than hydrating on its own.
