National Dish Iceland: Harðfiskur með Smjöri (Recipe)
In this article
Few things say Iceland quite like Harðfiskur með Smjöri — feather-light strips of wind-dried fish, torn by hand and spread thickly with cold, creamy butter. It is a snack born of the North Atlantic wind, made with nothing more than fish, air and time, and it has sustained Icelanders for centuries. Crisp, savoury and surprisingly moreish, it takes minutes to put together and delivers a genuine taste of the island’s larder.
About Harðfiskur með Smjöri
Harðfiskur með Smjöri is a traditional Icelandic dish that embodies the harsh conditions of the northern landscape. Preparing dried fish — usually cod — has a long history in Iceland and stands as proof of the art of preserving food without modern technology. The dried fish has a crisp, papery texture and an intense flavour that is perfectly rounded off by a generous layer of creamy butter. It is not only remarkably simple to prepare but also a genuine delicacy, offering a unique window into Icelandic gastronomy.
Ingredients (serves 1–2)
- 100g harðfiskur (dried cod or another dried fish)
- 50g butter, at room temperature
- A pinch of sea salt (optional, for extra flavour)
- Fresh bread or crispbread, to serve
Shopping for the ingredients
The ingredients for this dish are relatively easy to track down. Harðfiskur can be found in specialist food shops or in Nordic and Icelandic grocers. If you live in a larger city there are often online retailers stocking these products as well. Take care to choose fresh, good-quality butter, as it makes all the difference to the final result — the same principle that applies to a plate of Flatbraud Med Smjoeri.
Preparing the dish
Preparing Harðfiskur með Smjöri could hardly be simpler. First, make sure the butter has come up to room temperature so that it spreads easily. If you like to use sea salt, you can mix a little into the butter at this stage to underline the natural flavour of the fish. It is also worth laying out the bread in advance, as it makes the perfect accompaniment to the fish.
Step-by-step instructions
- Tear or cut the dried fish (harðfiskur) into small, manageable pieces.
- Spread the butter evenly over the slices of bread or crispbread.
- Lay the pieces of harðfiskur on top of the buttered bread.
- Optional: scatter over a pinch of sea salt.
- Serve and enjoy straight away.
Gluten-free / lactose-free version
To make Harðfiskur með Smjöri gluten-free, use one of the widely available gluten-free crispbreads or plain rice cakes in place of ordinary bread. For the butter, you can turn to plant-based alternatives such as margarine or a good vegetable-oil spread. These options make sure the dish can be enjoyed without lactose. When shopping, check that your ingredients are clearly labelled “gluten-free” or “lactose-free”.
Tips for vegans and vegetarians
While harðfiskur traditionally contains fish, you might consider a vegan alternative by using sun-dried tomatoes or thinly sliced seitan to mimic the savoury, chewy character. These ingredients are not only tasty but also endlessly versatile. Be sure to replace the butter with a plant-based margarine and enjoy the dish in an adapted vegan version. That way the original spirit of the recipe survives while remaining open to everyone.
More tips and tricks
The single most important tip for a perfect result is to use high-quality ingredients. Line-caught fish or locally sourced products can make all the difference. Experiment with different seasonings to adjust the dish to your own taste. Adding fresh herbs such as dill or parsley can open up new layers of flavour and lift the whole plate to another level — dill works just as beautifully in Raekjusalat Med Dill.
Adapting the recipe to your taste
One of the great virtues of Harðfiskur með Smjöri is its flexibility. If you like a bit of heat, you can add chilli flakes or a dash of hot sauce to give the dish a spicy edge. Alternatively, diced avocado makes an extra creamy component that enriches every bite. There are no limits to what you can try, so everyone can shape it exactly to their own liking.
Ingredient substitutions
If harðfiskur is not available, you can fall back on dried mackerel or sardines, which are similar in flavour. For the butter, vegan alternatives work equally well and cover most special dietary requirements. Olive oil is also excellent if you are after something lighter. These substitutions deliver a comparable texture and taste experience, much as smoked fish does in Reyktur Lax.
Drink pairing ideas
A number of drinks go beautifully with Harðfiskur með Smjöri. A light Icelandic beer or a crisp cider makes a refreshing companion. A herbal tea or simply sparkling water also suits the intense flavour of the fish very well. Choose a drink that underlines the flavours of the dish and rounds out the overall experience.
Serving and presentation ideas
Presentation plays an important part in this dish. Serve Harðfiskur með Smjöri on a rustic wooden board to underline its Nordic character. Garnish with fresh herbs or a few citrus slices for a touch of colour. You can also offer small bowls of different dips alongside, which makes the eating more interactive and adds to the enjoyment.
A bit of history
Harðfiskur has a long tradition in Iceland and is a relic of life before modern preservation methods. Historically the fish was dried in cold, windy weather so that it would keep for months at a time. This method is typical of Northern European cooking and shows clearly what resources people actually had to hand. The dish remains an important part of Icelandic culture to this day and, like so much of Icelandic cuisine, speaks of a close relationship with the natural world — a thread that also runs through Hakarl.
