Every year on the evening of 10 November, kitchens across southern Sweden and Denmark fill with the smell of roasting bird. In Skåne it is a goose, preceded by a dark, spiced soup made with goose blood. In Denmark it is usually a duck, stuffed with apples and prunes and served with caramelised potatoes. The Swedes call the night Mårten Gås (or Mårtensafton); the Danes call it Mortensaften. Both are named after the same man: Saint Martin of Tours, a fourth-century soldier-turned-bishop who, legend says, was betrayed by a flock of noisy geese.
It is one of the least known Scandinavian food traditions outside the region, yet for many families it is the start of the dark-season feasting that runs through Lucia and into Christmas. Here is where St Martin’s Eve came from, what goes on the table, and how to celebrate it at home.
Who was St Martin, and why the goose?
Martin of Tours was born around 316 in what is now Hungary and served as a soldier in the Roman army before leaving to devote himself to the Church. He founded one of the first monasteries in Gaul and became one of the most popular saints of medieval Europe. His feast day is 11 November, so the celebration traditionally takes place on the evening before.
The goose comes from a legend. When the people of Tours wanted to make Martin their bishop in 371, the humble monk did not want the job and hid in a goose pen. The geese cackled so loudly that he was found and duly made bishop. In the folk version, the geese paid for their gossip by ending up on the dinner table once a year.
The practical explanation is just as convincing. Martinmas fell at the natural end of the farming year. The harvest was in, geese had been fattened on the stubble of the fields, and animals that could not be fed through winter were slaughtered. In many places it was also the day servants and farmhands changed employers and were paid. A fat goose was the obvious way to mark the moment before the lean months began.
A Lutheran twist
Martin Luther was born on 10 November 1483 and baptised the next day, St Martin’s Day, which is why he was given the saint’s name. After the Reformation, when saints’ days lost much of their religious weight in the Nordic countries, some people came to link the evening with Luther instead. Today most Swedes and Danes see it simply as a food tradition, whichever Martin they have in mind.
Mårten Gås: Skåne’s goose dinner
The goose custom reached Sweden from the continent, most likely via Germany. According to Nordiska museet, there are records of goose being eaten on St Martin’s Eve from the 1500s, but at first it was a meal for the nobility and wealthy town dwellers. Goose farming only became common on Skåne farms in the 1800s, and around the same time restaurants in the south began serving goose dinners for the occasion. That is why Mårten Gås today is so strongly tied to Skåne, the fertile southern province around Malmö, Lund and Ystad (familiar to crime fiction fans as Kurt Wallander country).
A proper Mårten Gås dinner, or gåsamiddag, usually has three courses.
Starter: svartsoppa (black soup)
The most talked-about part of the meal is svartsoppa, a dark, glossy soup made from goose blood (pig’s blood was often used in the past) mixed with stock and fruit purée and seasoned with warming spices such as cloves, ginger, allspice and cinnamon. A splash of wine, port, Madeira or cognac is common. The result is sweet, sour and spiced at the same time, closer to a thick sauce than a broth.
It is served with an array of garnishes: slices of gåsleverkorv (goose liver sausage), stewed prunes, apple slices and sometimes boiled potatoes. It is an acquired taste, and plenty of Swedes skip it, but for traditionalists the dinner is not complete without it.
Main course: roast goose
The goose itself is stuffed with apples and prunes, roasted slowly so that the fat renders and the skin turns crisp, and served with red cabbage, Brussels sprouts, boiled or roast potatoes and a rich gravy made from the pan juices. Many cooks add a spoonful of lingonberries or apple sauce on the side. The goose fat is carefully saved for roasting potatoes later in the winter.
Dessert: spettkaka or apple cake
The classic Skåne dessert is spettkaka, a tall, lacy cake made from eggs, sugar and potato flour that is piped onto a rotating spit over an open fire. It is so delicate and labour-intensive that most people buy it from a specialist bakery. Others finish with a simple apple cake and vanilla sauce, a nod to Skåne’s orchards, which also supply much of Sweden’s cider.
Mortensaften: Denmark’s duck night
In Denmark the saint is known as Morten Bisp (Bishop Morten), and the evening of 10 November is Mortensaften. The Danish tradition is first documented in the early 1600s and, as in Sweden, goose was originally the meal of the well-off. Over time most Danish families swapped the goose for duck, which is cheaper, smaller and easier to fit into a home oven. Some families with older members still insist on goose, and some restaurants offer both.
The Danish menu will look familiar to anyone who has eaten a Danish Christmas dinner, because it is essentially a preview of it:
- Roast duck (andesteg) stuffed with apples and prunes
- Brunede kartofler, small potatoes caramelised in butter and sugar
- Rødkål, sweet-and-sour braised red cabbage
- Sauce made from the duck juices, often with a little cream and redcurrant jelly
- Boiled potatoes on the side for those who find the caramelised ones too sweet
If you would like a quicker weeknight version of the flavours, our recipe for Danish duck breast with orange sauce (andebryst) is a good place to start.
Mortensaften is not a public holiday, and many younger Danes treat it as optional. But it remains a popular reason to gather the family on a dark November weeknight, and some schools and kindergartens tell the story of Morten and the geese.

What about Norway, Finland and the rest of the Nordics?
St Martin’s Day is far less prominent elsewhere in the Nordic region. In Norway, Mortensmesse appears on the old runic calendar sticks (primstav) as a marker of the coming winter, but there is no widespread goose or duck dinner. In Finland the autumn feasting traditionally belonged to kekri, the old harvest festival held around the start of November, and Martinmas never developed into a food holiday of its own. Iceland and the Faroe Islands have no strong St Martin’s tradition either. Mårten Gås and Mortensaften are, in practice, a southern Scandinavian custom, shared across the Øresund strait by two regions that were once part of the same kingdom: Skåne belonged to Denmark until 1658.
Weather lore and old sayings
Like many old saints’ days, Martinmas came with weather predictions. One Swedish saying holds that if there is snow on St Martin’s Day, the ground will be bare by St Andrew’s Day (30 November), and the other way around. Farmers also looked at the goose itself: the colour of its breastbone was said to foretell whether the winter would be hard or mild. Nobody takes these seriously any more, but they show how firmly the day marked the turn from autumn to winter.
How to celebrate St Martin’s Eve at home
You do not need to live in Malmö or Odense to join in. A few tips:
- Pick your bird. A goose of 4 to 5 kg feeds six to eight people; a duck of around 2.5 kg feeds three to four. Order early, as butchers in Scandinavia often sell out in the week before 10 November.
- Stuff with fruit, not bread. Quartered tart apples and pitted prunes, plus a few sprigs of thyme or marjoram, are all you need. The fruit flavours the meat and becomes part of the garnish.
- Go low and slow. Roast at around 160 °C, allowing roughly an hour per kilo for goose and a little less for duck, pouring off the fat as it collects. Finish with a blast of high heat to crisp the skin.
- Make the red cabbage a day ahead. Like most braises, rødkål and rödkål taste better the next day.
- Try the soup if you dare. Some Swedish supermarkets sell ready-made svartsoppa in November, which is the easiest way to taste it without sourcing goose blood.
- Drink something warming. Red wine is the usual pairing, but a small glass of aquavit or an early batch of glögg suits the season.
Eating out: Mårten Gås and Mortensaften in restaurants
If you are travelling, look out for set “gåsamiddag” menus at inns, castles and country restaurants across Skåne in the first weeks of November; many are booked months in advance. Stockholm and Gothenburg restaurants increasingly offer them too. In Denmark, traditional restaurants and old inns (kroer) serve Mortensaften menus, and Copenhagen is a good base for finding one. See our Copenhagen city guide or head to Funen with our Odense travel guide for countryside inns.
The opening act of the Nordic feast season
Mårten Gås and Mortensaften are small, regional and easy to overlook, but they hold a special place in the Scandinavian calendar. They are the first big shared meal of the dark season, a last celebration of the harvest before winter, and a rehearsal for the Christmas table. Once the goose bones are cleared away, attention turns to Christmas markets, saffron buns for Lucia, and the full spread of the Swedish julbord. If you want a taste of how Scandinavians mark the turn of the year, a plate of roast goose or duck on 10 November is a delicious place to begin.
