Krupnik - Traditional Polish Barley Soup

Krupnik is one of my favourite soups from childhood and a staple of Polish home cooking. It is a clear poultry broth with fine pearl barley, potato and simple vegetables, filling without being heavy, finished with a little cream tempered in at the end so it does not split.

I build mine on a whole poussin, simmered gently for an hour and then shredded back into the broth, but any chicken pieces on the bone will do the same job. The barley is what decides the soup: more of it and you get the thick, almost gooey krupnik I grew up on, less and it stays brothy.

One thing worth saying: krupnik is also the name of a Polish honey vodka. This is the soup. Soup comes first at almost every Polish meal, and my guide to Polish food lays out the others worth knowing.

Why You’ll Love This Krupnik

This krupnik is simple on the surface, but a few small choices make a big difference to how the soup turns out. Cooking the bouillon first and only then building the soup keeps the broth clean and prevents the barley and vegetables from breaking down too much. It also gives you much better control over the final flavour.

Using small-grain pearl barley is another key detail. It cooks evenly and thickens the soup gently, so the krupnik stays comforting rather than heavy. Larger barley can easily overpower the broth if you’re not careful.

Seasoning is added only once the soup comes together. By using Kucharek at that stage, the flavour stays balanced and you avoid over-salting the bouillon. Finally, the soup is finished with a little cream, tempered first so it blends smoothly and just softens the edges of the flavour without turning the krupnik into a creamy soup.

These are the kinds of details that come from cooking this soup many times at home, and they’re what make this version reliable every time.

Kucharek and Vegeta Seasoning in Polish Cooking

If you grew up in a Polish kitchen, chances are Kucharek or Vegeta were always within reach. These seasoning blends have been used for decades and are a familiar shortcut for building savoury depth in soups, stews and sauces. They combine salt with dried vegetables and spices, which is why they work so well in simple dishes like krupnik.

In this recipe, Kucharek (or Vegeta) is added only when the soup is built, not during the bouillon stage. This gives better control over seasoning and keeps the broth clean. A small amount is enough to bring everything together without overpowering the natural flavour of the chicken and barley.

If you don’t have Kucharek or Vegeta, simply season the soup with salt to taste instead. The krupnik will still be delicious, just slightly different from the flavour many of us remember from Polish home cooking.

Parsley Root, and Why It Is Not a Small Parsnip

This is the question English speakers ask about krupnik more than any other, and it is worth answering properly because the two things sit next to each other on a market stall and look almost identical.

Parsley root (pietruszka) is exactly what it sounds like: the taproot of a variety of parsley grown for its root rather than its leaves. It tastes of parsley, green and slightly peppery, with a clean finish. Parsnip (pasternak) is a different plant altogether and it is sweet, almost sugary when cooked. Swap one for the other and the soup does not fail, but it goes noticeably sweeter, and Poles cooking abroad make this substitution by accident all the time.

My version does not use either. I build the bouillon on a celery stalk instead, which keeps it savoury and lets the barley and the chicken carry the soup. If you can find parsley root, add one alongside the carrot and you will have something closer to what most Polish kitchens make. If all you can find is parsnip, use half of one, not a whole.

About the Barley (Kasza) Used for Krupnik

The type of barley you use makes a real difference to how krupnik turns out. For this soup, I always use small-grain pearl barley (kasza jęczmienna drobna), which is finer than the more common large pearl or “wiejska” barley.

Small-grain barley cooks more evenly and releases its starch gradually, which helps the soup thicken naturally without becoming heavy or gluey. It blends into the broth rather than dominating it, so every spoonful tastes balanced and comforting.

Larger barley grains absorb more liquid and swell much more as they cook. If used here without adjustment, they can quickly turn krupnik into something closer to a stew than a soup. That’s why this finer barley is such an important detail in this recipe.

If you can’t find small-grain barley, you can still make the soup, but it’s worth reducing the amount slightly or cooking the barley separately and adding it towards the end.

What Chicken to Use for Krupnik

Krupnik is very forgiving when it comes to the choice of chicken. Any chicken parts on the bone will work well, as the flavour comes mainly from the bones and gentle simmering rather than from a specific cut.

In this recipe, I use a whole poussin because it has a lot of flavour and a good amount of breast meat, which stays tender once cooked and added back to the soup. The bones give the bouillon depth, while the meat keeps the soup filling without feeling heavy.

That said, chicken legs, thighs, wings, or even a leftover carcass will all work just as well. The key is to use chicken on the bone. Boneless cuts won’t give the same depth of flavour, even if the soup itself is well seasoned. My chicken guide goes through which cut I use for what.

Krupnik is only as good as the stock under it, and people ask me for a proper rosół. I have never written one up. Lois at Polish Housewife has a rosół I like very much, so that is where I send them.

How to Make Krupnik, Step by Step

1. Put the poussin in a big pot and cover it with cold water. Cold, not hot, and only just covering it. Use a pot of at least four litres.Starting cold draws the flavour out of the bird slowly into the water, which is the point of a bouillon. Boiling water seals the outside and keeps more of it in the meat. A big pot leaves room to skim.
2. In go the vegetables and aromatics. Onions, carrot, celery, garlic, bay and allspice, whole or halved, not chopped.Big pieces give up their flavour over the hour and then lift straight out. Diced vegetables would fall apart and cloud the broth.
3. Bring it up slowly and simmer, covered, for an hour. Slowly is what matters. Keep it at a bare tremble, the odd bubble, not a churn.A gentle stock stays clear. A hard boil mixes the fat into the liquid, so it turns cloudy and greasy instead of the fat sitting on top where you can skim it off.
4. Lift everything out and keep what you need. Take out the bird and all the vegetables. The onion, celery, bay and allspice go in the bin. Keep the carrot and the garlic cloves for later.The softened garlic is what makes this soup mine rather than a standard krupnik.
5. Strip the meat and return it to the pot. Skin and bones out, meat pulled into pieces and back into the broth. Do it while the bird is still warm.Warm, the meat falls off. Cold, you will be prising it. A poussin gives less meat than you expect, which is right here: krupnik is a barley soup with chicken in it, not a chicken soup.
6. Add the potatoes, the barley and the saved garlic. Dice the potatoes small. 80 g of barley in two litres gives a brothy soup. Go to 120 or 140 g for the thick, almost porridge-like version most Polish households would know.Small potatoes cook in the same time as the barley. The barley is the whole texture of the dish, so this is where you choose what kind of krupnik you get.
7. Season with Kucharek and pepper. Go lighter than you think. You will taste again at the end.The barley soaks up seasoning as it swells and the soup reduces a little, so what tastes right now can taste salty in twenty minutes.
8. Simmer covered for 15 to 20 minutes, until the barley is tender. Bite a grain to check, do not go by the clock. With pot barley (pęczak) or ordinary pearl barley, give it 30 minutes or more and add water as needed.Fifteen to twenty minutes is right for the fine barley this recipe uses. Coarser grains take longer and drink far more.
9. Stir the diced carrot in and turn the heat off.The carrot is already cooked from its hour in the bouillon, so it only needs warming through. Added early it goes to mush and loses its colour.
10. Temper the cream before it goes anywhere near the pot. Ladle a little hot soup into the cream and stir, then a little more, then stir the loosened cream into the pot, which should be off the heat by now.Poured straight from the tub into hot soup, cream can split into threads, and you cannot bring it back.
11. Taste, adjust and serve with parsley. This is the seasoning that counts. When you reheat it the next day, loosen it with a splash of water or stock.By now the barley has taken what it wants and the cream has softened everything. The barley keeps soaking up liquid overnight, so it will be thicker tomorrow.

Instructions

Tap a step to tick it off as you cook.

Prepare the Poultry Bouillon

1

Cover the Poussin with Cold Water

Put the whole poussin in a large pot of at least 4 litres and cover it with cold water, only just. Starting cold lets the flavour draw out slowly, and the big pot gives you room to skim.

2

Add Vegetables and Aromatics to the Pot

Add the carrots, garlic, onions, celery, bay leaves and allspice, whole or halved rather than chopped. Big pieces give up their flavour over the hour and lift straight out, where diced ones would cloud the broth.

3

Simmer the Bouillon Gently

Bring slowly to a boil, then reduce the heat so the liquid only gently simmers. Cover and cook for 60 minutes, until the meat is tender and the bouillon well flavoured.

4

Remove Meat and Vegetables to Finish the Bouillon

Remove the poussin and all vegetables and aromatics from the pot. Discard onions, celery, bay leaves, and allspice. Set the meat aside to cool slightly. At this stage, the pot should contain clear poultry bouillon only.

Prepare Krupnik Soup

5

Return the Cooked Poussin Meat to the Bouillon

Strip the meat from the poussin while it is still warm, discarding the skin and bones, and return it to the bouillon. It falls off the bone warm and has to be prised off once cold.

6

Add Potatoes, Small-Grain Barley, and Garlic

Add the diced potatoes, small-grain barley and the saved garlic cloves. Dice the potatoes small so they cook in the same time as the barley.

7

Season the Soup with Kucharek and Black Pepper

Season with Kucharek and black pepper, but go lighter than you think. The barley soaks up seasoning as it swells, so taste again at the end.

8

Simmer Until Barley and Potatoes Are Tender

Bring to a boil, then reduce to a gentle simmer. Cook covered for 15-20 minutes or until potatoes and barley are cooked through.

9

Add Diced Carrot and Stop the Cooking

Stir in the diced carrot saved from the bouillon and turn off the heat. It is already cooked, so it only needs warming through, and adding it earlier turns it to mush.

10

Temper and Add the Cream

Temper the cream in a bowl by stirring in a ladle of hot soup, then another, before stirring it back into the pot gently. Poured straight from the tub into hot soup, it can split into threads.

11

Adjust Seasoning and Serve

Taste and adjust the seasoning now, once the barley has taken what it wants. Serve hot with chopped parsley. It thickens overnight, so loosen it with a splash of water or stock when you reheat.

Chef’s notes＋

• Start the bird in COLD water and bring it up slowly. A stock held at a bare tremble stays clear; boiled hard it turns cloudy and greasy.
• 80 g of barley gives a brothy soup. Use 120 to 140 g for the thick, almost porridge-like krupnik, and expect to loosen it the next day either way.
• 15 to 20 minutes is right for fine-grain kasza only. Pot or pearl barley needs 30 minutes or more and drinks far more liquid.
• Temper the cream with a few ladles of hot soup before it goes in, off the heat, or it can split into threads and there is no way back.

What to Serve With Krupnik

Serve the krupnik hot and season it to taste in the bowl. If you like, a small splash of Maggi added just before eating is a very traditional touch and something many of us grew up with. These days I also cook this soup for my toddler daughter, and she absolutely loves it, which makes it even more special for me. I hope you enjoy this lovely Polish soup as much as we do: it’s simple, comforting, and truly feels like home.

FAQ for Krupnik

A Few Words from the Chef

How thick your krupnik turns out is all down to the barley, and that is personal. I like plenty of it, which makes the soup lovely and thick, almost gooey. If you prefer a lighter, more brothy soup, simply use less barley. Cook it your way: that is the beauty of a home soup.
