Iceland’s food culture is inseparable from its geography. For most of Icelandic history, the island had no grains, no orchards, and no overland trade routes. Everything that Icelanders ate had to be produced locally or preserved through the winter - and that constraint shaped a culinary tradition unlike anywhere else in the Nordic world.
Skyr: Iceland’s Oldest Food
Skyr has been made in Iceland for over 1,000 years. It predates Eddic poetry, predates Snorri Sturluson, and predates most of the buildings visible in the Reykjavík skyline. Early Icelandic settlers brought the technique from Scandinavia in the ninth century, but it died out on the continent while Iceland continued making it uninterrupted.
Skyr is technically not yoghurt - it is a fresh acid-set cheese from which the whey has been removed, then cultured with live bacteria. The result is thicker than Greek yoghurt, lower in fat, and higher in protein. Traditional Icelandic skyr was made with a small quantity reserved from the previous batch to inoculate the new one - a continuous chain of bacterial culture that, in some Icelandic farms, was maintained for generations.
The modern industrial version (Skyr Íslenskur, or brands now sold internationally) is broadly similar but produced at scale. Small dairies in North Iceland, particularly around Akureyri and the Skagafjörður valley, still make skyr in smaller batches with noticeably different texture - grainier, tangier, and less uniform than the supermarket version.
Skyr was historically eaten with milk and crowberries (krækiber, the small dark berries that grow across Icelandic lava fields). Modern Icelandic breakfast tables serve it with honey, blueberries, or granola - but the crowberry version, particularly from late August onwards when the berries ripen, is the most Icelandic way to eat it.
Lamb: The Architecture of Icelandic Cooking
Icelandic sheep are unlike commercial European breeds. Descended from the animals brought by Viking settlers in the ninth century, they have been geographically isolated for over 1,100 years with minimal cross-breeding. They roam Iceland’s interior highlands from May to September, eating wild grasses, angelica, Arctic thyme, and heather. The meat is leaner, more intensely flavoured, and more aromatic than standard commercial lamb - closer in character to mountain mutton.
The most important lamb preparation in Icelandic tradition is hangikjöt - smoked lamb. The smoking was originally done over dried sheep dung (tað), which gives the meat a distinctive, slightly sweet smoke note that birchwood or beech does not replicate. Traditional hangikjöt is eaten cold, sliced thin, on rye bread with béchamel sauce and pickled red cabbage. It is the centrepiece of the Icelandic Christmas table and appears on café menus as an open sandwich year-round.
Kjötsúpa (lamb soup) is the other essential preparation - a bone broth made with lamb neck or shoulder, turnips, carrots, potatoes, and rice. It is Iceland’s comfort food and its most democratic dish: every household makes it, every rural café serves it, and the recipe varies only in proportion. The broth is made long - typically two to three hours - and the result is deeply savoury in a way that a short-simmered stock never achieves.
Lamb chops (lamb kotilletar) are grilled simply - salt, pepper, and a hot pan. The quality of the meat makes complexity unnecessary. Icelandic restaurants that serve them well tend to leave them rare.
Harðfiskur: Viking Protein
Harðfiskur is air-dried fish, most often cod or haddock, hung in frames in the cold north Atlantic wind until completely desiccated. The process removes roughly 80% of the fish’s water content, concentrating the protein and extending the shelf life to months or years. Vikings carried it on voyages across the North Atlantic. Basque fishermen traded for it in medieval Iceland. It was Iceland’s primary export commodity for centuries.
The eating is simple: tear a strip from the stiff, pale-beige plank of dried fish and eat it with salted butter. The texture starts hard and becomes progressively more pliable as you chew; the flavour is intensely savory and slightly mineral. It requires more jaw work than most modern foods, which is perhaps why younger Icelanders tend to eat it less than older generations - but it remains the most purely Icelandic snack food in existence, and the best version to try is bought loose at Kolaportið flea market by the Reykjavík harbour rather than vacuum-sealed from a supermarket.
Hverabrauð: Bread Baked in the Earth
Geothermal rye bread - hverabrauð or lava bread - is baked underground in pots buried in geothermally heated ground, typically for 24 hours at around 100°C. The process creates a bread unlike anything made in a conventional oven: dense, dark, very slightly sweet, with a moist crumb that holds together rather than crumbling.
The technique is most associated with the Mývatn area in North Iceland, where volcanic activity keeps the ground hot at shallow depth. At the Mývatn Nature Baths and at Vogafjós farm restaurant near Reykjahlíð, bread is pulled directly from the earth in sealed pots as part of the meal service. In Reykjavík, the tradition is maintained in some kitchens though without genuine geothermal heat - the bread is recognisably similar but not identical.
Hverabrauð is traditionally eaten with butter and smoked fish (usually Arctic char or smoked lamb) and served alongside skyr at farm breakfasts. It is not a bread you eat in quantity - it is dense and filling. One or two slices is a meaningful portion.
Hákarl and the Logic of Fermentation
Fermented Greenlandic shark - hákarl - is the food most closely associated with Iceland internationally, usually by people who have never eaten it and often misrepresented as a Viking delicacy. The reality is more specific and more interesting.
Greenlandic shark (Somniosus microcephalus) is toxic when fresh, containing high concentrations of trimethylamine oxide. The traditional fermentation process - burying the shark in gravel pits and allowing it to drain and break down over several months, then hanging it to dry - converts the toxins into harmless amines and produces an edible (if pungent) product. The ammonia smell is genuine; the flavour, once past the initial shock, is closer to very strong blue cheese than to anything fishy.
Hákarl is not a daily food for Icelanders. It appears at midwinter festivals (þorrablót, held in January and February), served alongside other traditional preserved foods - singed sheep’s head (svið), blood pudding (blóðmör), liver sausage (lifrarpylsa), and pickled ram’s testicles (súrsaðir hrútspungar). Þorrablót is less a gastronomic occasion than a cultural ritual - an opportunity to eat the foods that kept Icelanders alive for a thousand winters and to appreciate, at a distance of one century, how hard those winters were.
New Nordic Iceland
Iceland’s contemporary restaurant scene exists in a specific relationship with its Nordic neighbours. When the New Nordic Cuisine movement emerged from Copenhagen in the 2000s - centred on local ingredients, traditional preservation techniques, and seasonal constraint - Icelandic chefs recognised something already present in their own food culture: the reliance on preservation, the intimacy with a specific and unforgiving landscape, the long-standing use of fermentation and smoke.
The result has been a generation of Icelandic chefs who take traditional ingredients seriously rather than importing aspirational ones. Arctic char is served raw. Angelica (hvönn), wild throughout Iceland, appears as seasoning. Seaweed from Breiðafjörður is dried and ground. Icelandic salt - harvested from North Atlantic seawater by producers near Reykjanes - has won international attention.
This is not cuisine built from imports. The constraint that shaped Icelandic food for a thousand years - you eat what the landscape provides - is now reframed as a culinary philosophy. The outcome is a food culture with one of the clearest senses of terroir in the world.
What Icelanders Actually Eat at Home
All of the above is the ceremonial and cultural layer. Daily Icelandic eating is considerably more ordinary. Skyr for breakfast, an open-faced sandwich (smörbrauð) for lunch, and a dinner that is likely lamb, chicken, or fish with boiled potatoes and vegetables. Icelandic home cooking is not particularly elaborate - it reflects a farming and fishing culture where meals were sustenance rather than entertainment.
Pylsur (the Icelandic lamb hot dog) is genuinely what many Icelanders eat when they don’t want to cook. Supermarket sushi is a lunchtime staple. Pizza and pasta, absorbed from Italian and American influence, are eaten regularly. Alcohol is expensive enough that home consumption (bought from the state monopoly Vínbúðin) vastly outweighs restaurant consumption - Icelanders rarely drink out as often as Reykjavík’s bar scene might suggest.
The gap between traditional food culture and daily food habits is not hypocrisy - it is what happens to every food culture that industrialises rapidly. Iceland went from subsistence farming to full modernity faster than almost any country in the twentieth century. The foods that preserved the culture survive as ceremony, as identity, and - increasingly - as culinary distinction.
