National Dish Finland: Hernekeitto (Recipe)
In this article
Discover Hernekeitto, the thick, warming pea soup that Finns have been ladling out for centuries. Made from humble dried peas, a handful of root vegetables and a good broth, it is the kind of honest cooking that fills a kitchen with comfort on a grey winter afternoon. Simple enough for a first-time cook, satisfying enough to become a weekly habit — and traditionally eaten on Thursdays across Finland.
About Hernekeitto
Hernekeitto, the classic Finnish pea soup, wins people over not only with its hearty flavour but also with how straightforward it is to make. This traditional dish is a fixture of Finnish food culture and is especially popular during the colder months of the year. The soup relies on a small number of good-quality ingredients that together produce something nourishing and genuinely filling. Its uncomplicated method makes it just as suitable for beginners as for seasoned cooks.
Ingredients (serves 1–2)
- 250 g dried green peas
- 1 onion
- 1 carrot
- 1 piece of celeriac (about 50 g)
- 1 litre vegetable or meat stock
- Salt and pepper, to taste
- Optional: smoked meat (bacon, for example)
Shopping for the ingredients
Making Hernekeitto calls for a mix of fresh and dried ingredients. Head to your local supermarket or a good greengrocer to find the best dried green peas and the freshest vegetables. Check that the peas are of decent quality and take a look at the best-before date, since older peas take considerably longer to soften. Fresh onions and carrots carry much of the flavour here, so choose organic produce where you can — the same principle that pays off in a bowl of Vihanneskeitto.
Preparing the dish
Before you start cooking Hernekeitto, it is important to soak the dried peas overnight in plenty of cold water. This shortens the cooking time considerably and gives the soup a much better consistency. The next day, drain and rinse the peas thoroughly. While that is happening, wash the onion, carrot and celeriac and cut them into small, even dice so everything cooks at the same rate.
Step-by-step instructions
- Put the soaked peas into a large pan along with the chopped vegetables.
- Pour in the stock and bring everything to the boil.
- Turn the heat down and let the soup simmer for about an hour, until the peas are soft.
- Blend the soup with a stick blender until it reaches the consistency you like.
- Season to taste with salt and pepper.
- Optional: add the smoked meat and warm it through briefly.
Gluten-free / lactose-free version
Hernekeitto is naturally gluten-free and lactose-free, provided you avoid additions such as cream or stocks that may contain gluten-based ingredients. When buying stock, check the label to make sure it is certified gluten-free — stock cubes are a common hidden source. The soup itself is an excellent choice for anyone managing allergies or intolerances, and needs no special substitutions to get there.
Tips for vegans and vegetarians
To make Hernekeitto suitable for vegans and vegetarians, simply swap the meat stock for a well-flavoured vegetable stock. The quality of your ingredients matters more than usual in a soup this simple, so pick fresh, seasonal vegetables for the best result. Smoked spices such as smoked paprika are worth adding too: they lend the soup the extra depth that the meat would normally provide, much as they do in Kasvispihvit.
More tips and tricks
When making Hernekeitto it pays to be a little adventurous. Herbs such as thyme or a bay leaf dropped into the cooking liquid will enrich the flavour noticeably, and a squeeze of lemon just before serving helps refresh the aromas after the long simmer. Do not skip the garnish either — fresh dill or parsley scattered over the top brings a welcome brightness to what is otherwise a very earthy bowl.
Adapting the recipe to your taste
Depending on your own preferences, the Hernekeitto recipe is easy to adjust. Add your favourite vegetables, or change the type of pea you use. Play with the consistency as well: more liquid gives you a lighter, brothier soup, less gives you something closer to a thick purée that almost stands a spoon up. That flexibility is exactly what makes this dish so enduring and leaves plenty of room for creative tweaks.
Ingredient substitutions
If you have no green peas to hand, yellow split peas work just as well and produce an equally hearty result. Instead of shop-bought vegetable stock, homemade stock will intensify the flavour considerably. As for the smoky element, the options are wide open — try smoked tofu in place of bacon for a smoky note without the meat, or take inspiration from the smoked flavours in Savuporokeitto.
Drink pairing ideas
A warm bowl of Hernekeitto goes very nicely with something light and lively to drink. A pale beer or a dry white wine harmonises beautifully with the savoury soup and cuts through its richness. For an alcohol-free alternative, a ginger or herbal tea works well, its spicy aroma echoing the seasoning in the pan. It is worth experimenting with a few different drinks to find the pairing you like best.
Serving and presentation ideas
The presentation of your Hernekeitto can be lifted with a few simple touches. Serve the soup in brightly coloured bowls to set off its muted green. Fresh herbs scattered on top add visual appeal as well as flavour, and a swirl of mustard — the traditional Finnish accompaniment — looks striking against the surface. Some crisp pieces of bread served alongside, such as Ruisleipae, add texture and round out the meal.
A bit of history
Hernekeitto has a long history in Finland and is closely associated with the country’s Independence Day. It was originally cooked as a plain but nourishing meal for working people, made from ingredients that stored well through the long northern winter. Over the decades it has grown into a comfort dish that many Finns link with childhood memories — and the Thursday pea soup tradition, still followed in schools, canteens and the armed forces, keeps it firmly in daily life. That history is part of what makes this pillar of Finnish cuisine such a natural choice on a cold day.
