Ingredients
  • pearl barley, rinsed 80g dry
  • chestnut mushrooms, thickly sliced 200g
  • dried porcini mushrooms 10g
  • hot water (for soaking porcini) 200ml
  • onion, finely diced 1
  • carrot, diced small 1
  • celery sticks, sliced 2
  • garlic cloves, minced 2
  • vegetable stock 1 litre
  • olive oil 1 tsp
  • soy sauce 1 tbsp
  • flat-leaf parsley, chopped large handful
  • to taste salt & black pepper
Method
  1. 1

    Soak the dried porcini in 200ml hot water for 20 minutes. Drain, reserving the soaking liquid. Roughly chop the rehydrated porcini.

  2. 2

    Heat olive oil in a large pot over medium heat. Add onion and cook for 5 minutes until soft. Add carrot, celery, and garlic. Cook a further 4 minutes.

  3. 3

    Add chestnut mushrooms and the chopped porcini. Cook for 5–6 minutes until the mushrooms are golden and any liquid has evaporated.

  4. 4

    Add the rinsed pearl barley, vegetable stock, strained porcini soaking liquid, and soy sauce. Bring to a boil.

  5. 5

    Reduce heat, cover, and simmer for 35–40 minutes until barley is tender and the soup has thickened.

  6. 6

    Taste and adjust seasoning. The soy sauce adds depth without making it taste Asian — it should not be identifiable. Serve with a generous scatter of parsley.

💡 Natali's tip: Don't skip the dried porcini — they are the soul of this soup. The soaking liquid contains deep umami flavour; strain it through a fine mesh to remove any grit and add it straight to the pot.

In Poland and Belarus, barley mushroom soup — sometimes called krupnik — is the kind of meal that appears at every family table in winter. It is humble, thick, and deeply nourishing. The combination of fresh and dried mushrooms creates a broth that is genuinely complex without any meat.

Pearl barley is an underrated grain: rich in beta-glucan fibre (the same kind found in oats), filling, and slow-releasing. This soup is even better the day after it is made, as the barley continues to absorb the stock overnight.

Frequently asked questions

Can I make this soup gluten-free?

Pearl barley contains gluten. Swap it for buckwheat groats or brown rice — add them later in the cooking, as both cook faster than barley.

What if I can't find dried porcini?

Use extra chestnut mushrooms plus a teaspoon of soy sauce for the deep umami the porcini normally provide.

How long does it keep?

Up to 4 days in the fridge — the flavour improves overnight. The barley keeps thickening, so loosen with a splash of stock when reheating. Freezes well for 3 months.
