About Saltfiskur með Lauksmjöri
The traditional Icelandic dish Saltfiskur með Lauksmjöri offers a wonderful combination of salty stockfish and delicate onion butter. It is not only a genuine treat for the palate but also a fine example of Nordic cooking at its most straightforward.

Anyone who loves the tastes of the far north should try this recipe at least once.
Ingredients (serves 1–2)
- 250 g salted stockfish
- 100 g butter
- 1 large onion, finely chopped
- 2 tablespoons fresh parsley, chopped
- Salt and pepper to taste
- Optional: lemon juice, to finish
Shopping for the ingredients
When shopping for Saltfiskur með Lauksmjöri, pay close attention to the quality of the salt cod. It is stocked by many international grocers and is also easy to order online. Make sure the fish has been properly salted, as this is what gives the dish its authentic character. Fresh onions and good-quality butter matter just as much — they are what round the whole plate off.
Preparing the dish
Before you start cooking, the stockfish needs to soak in cold water for several hours. This draws out the excess salt and allows the full, rounded flavour of the fish to come through. Aim for at least six to eight hours of soaking for the best result, changing the water once or twice if you can. Once soaked, drain the fish thoroughly and cut it into evenly sized pieces.
Step-by-step instructions
- Bring the soaked stockfish to the boil in a pan of fresh water and cook for around 10 minutes.
- Meanwhile, heat the butter in a frying pan and sauté the finely chopped onion until translucent.
- Lift the cooked fish carefully out of the water and add it to the onion butter.
- Stir through the parsley and season with salt and pepper.
- Finish with a squeeze of lemon juice and serve warm.
Gluten-free / lactose-free version
For a gluten-free and lactose-free version of Saltfiskur með Lauksmjöri, simply replace the ordinary butter with a lactose-free alternative. Gluten-free accompaniments such as rice or quinoa work beautifully alongside it. The fish itself is naturally gluten-free, so the sides are the only thing to watch. With these small adjustments, everyone at the table can enjoy the dish regardless of dietary restrictions.
Tips for vegans and vegetarians
Although Saltfiskur með Lauksmjöri is a traditional fish dish, vegans and vegetarians can still enjoy similar flavours. In place of the stockfish, try braised vegetables such as courgette or aubergine, which take on the onion butter well. Plant-based spreads make an excellent stand-in for the dairy butter. That way the hearty character of Icelandic cuisine is within reach without using any animal products.
More tips and tricks
To get the very best from your dish, let the stockfish soak a few hours longer to reduce the salt content further. You can also vary the herbs and spices in the onion butter to make it more aromatic — a hint of garlic or a good grind of pepper brings welcome depth. When frying the onions, keep them pale and soft rather than dark, so the flavour stays mild and sweet. The same gentle approach pays off in a comforting bowl of Plokkfiskur.
Adapting the recipe to your taste
Adjusting Saltfiskur með Lauksmjöri to personal preference could hardly be simpler. If you like a bit of heat, stir some fresh chilli into the onion butter. The sides can change with the seasons too — a crisp salad or a bowl of mashed potato both suit the fish well. Experiment with herbs such as thyme or oregano to discover new directions for the dish.
Ingredient substitutions
If salted cod proves hard to find, seafood or even smoked fish make good alternatives and give the plate a slightly different accent — much as they do in Reyktur Lax. For a dairy-free version, olive oil or margarine can stand in for the butter. Whichever route you take, choose the freshest produce you can to keep the flavours bright. With sensible substitutions, the dish remains every bit as good.
Drink pairing ideas
Light white wines and Nordic beers are the natural partners for Saltfiskur með Lauksmjöri. A crisp Sauvignon Blanc complements the salty notes of the fish beautifully. If you prefer beer, look for an Icelandic craft ale or something with a gentle malty sweetness. Sparkling water with a slice of lemon is a refreshing non-alcoholic option that suits the dish just as well.
Serving and presentation ideas
Presentation goes a long way towards making Saltfiskur með Lauksmjöri feel like a delicacy. Serve it on a handsome plate and garnish with fresh herbs or lemon slices. Colourful sides such as a vegetable salad or crisp potato rösti add both interest and contrast, and a basket of Rugbraud on the side is very much in the Icelandic spirit. Do not forget to bring the onion butter to the table in a small dish so everyone can help themselves.
A bit of history
The tradition of Saltfiskur is rooted in Iceland’s fishing culture, which stretches back many centuries. Given the country’s geography, salting was essential to preserve fish through the long winter months. The dish is therefore not merely something good to eat but a piece of Icelandic history and culture in its own right — a lineage it shares with preserved specialities such as Hardfiskur. In recent years Saltfiskur með Lauksmjöri has found an international audience and now appears on menus in Nordic restaurants far beyond the island.
