What to Eat in Reykjavik: Kjotsupa Lamb Soup, Pylsur Hot Dogs, Arctic Char & Skyr

Shaped by cold, clean North Atlantic waters, summer highland pastures where sheep graze wild berries and Arctic thyme, and geothermal greenhouses heated by volcanic steam, Reykjavík's food scene bridges thousand-year-old Nordic preservation traditions with contemporary New Nordic cooking. Here are the five essential flavours to seek out across Miðborg and the Old Harbour.

1. Traditional Icelandic Lamb Soup (Kjötsúpa) & Slow-Roasted Highland Lamb

Since the ninth-century Settlement era, Icelandic sheep, a pure-bred northern short-tailed lineage unchanged for over a millennium, have roamed free across unfenced mountain valleys from June to September. The quintessential dish on a crisp Reykjavík afternoon is a steaming bowl of kjötsúpa (Icelandic meat soup): bone-in cuts of lamb shoulder and shank slow-simmered in a clear, rich broth thickened with rolled oats or pearl barley and loaded with golden rutabaga (rófur), potatoes, carrots, cabbage, and dried highland herbs.

2. The Icelandic Lamb Hot Dog (Pylsa): Ordering "Eina með öllu" Since 1937

Iceland's unofficial national street food is the pylsa, whose distinctive savoury flavour and crisp snap come from a sausage link made primarily of free-range Icelandic lamb blended with pork and beef in a natural casing. Join the queue at the tiny red-and-white kiosk of Bæjarins Beztu Pylsur ("The Best Hot Dogs in Town"), operating at Tryggvagata 1 between Austurvöllur and Harpa since 1937, and ask for "eina með öllu" ("one with everything"): tucked inside a steamed bun over a bed of raw chopped white onions and crunchy fried onions, then striped with ketchup, sweet brown pylsusinnep mustard, and tangy caper-and-gherkin remoulade.

3. Arctic Char (Bleikja), Atlantic Cod & Plokkfiskur with Geothermal Rye Bread

Along the Old Harbour and Grandi, fishermen land pristine Atlantic cod (þorskur), haddock (ýsa), cold-water langoustine (humar, prized in creamy langoustine bisque), and delicate pink Arctic char (bleikja) raised in glacial river water. For traditional home-style comfort, order a cast-iron skillet of plokkfiskur: flaked poached cod or haddock folded with boiled potatoes, sweet onions, white béchamel, and a gratin crust of melted cheese, always served alongside thick slices of dense, dark, molasses-sweetened rúgbrauð (geothermal rye bread) smeared with salted Icelandic butter.

4. Heirloom Skyr with Wild Bilberries

Brought to Iceland in wooden barrels by Norse settlers over 1,100 years ago, skyr looks like thick Greek yoghurt but is actually a strained skim-milk fresh cheese fermented with heirloom bacterial cultures and rennet. Naturally fat-free and packed with protein, it is traditionally served for breakfast or dessert topped with cold cream and wild dark-blue Icelandic bilberries (bláber) or crowberries.

5. Cardamom Knots & Cinnamon Snúður at Reykjavik's Artisan Bakeries

Fuel your morning walks at downtown bakeries such as colourful graffiti-facade Brauð & Co (on Frakkastígur) or fourth-generation Sandholt (on Laugavegur, founded 1920) with a warm sourdough cardamom bun or a classic coiled Icelandic snúður glazed with chocolate, caramel, or pink sugar icing alongside freshly roasted Nordic filter coffee.
