The Soul of Dutch Winter Cooking

There are few dishes more quintessentially Dutch than erwtensoep — a thick, hearty split pea soup traditionally eaten on cold winter days. So thick, in fact, that a Dutch saying holds a proper erwtensoep should be able to stand a spoon upright. It's the kind of dish that warms you from the inside out, filling the kitchen with a deep, smoky aroma that feels like home.

Traditionally served with roggebrood (Dutch rye bread) and sliced rookworst (smoked sausage) on the side, this soup is a complete meal. It's also one of those dishes that tastes even better the next day — making it perfect for batch cooking.

Ingredients (Serves 6–8)

  • 500g dried green split peas, rinsed
  • 1 smoked pork knuckle (or 200g smoked bacon lardons)
  • 1 rookworst (Dutch smoked sausage) — or a good-quality smoked sausage
  • 2 medium onions, diced
  • 3 stalks of celery (including leaves), sliced
  • 2 medium carrots, diced
  • 2 medium potatoes, peeled and diced
  • 1 leek, sliced
  • 2 litres water or light stock
  • Salt, white pepper, and fresh flat-leaf parsley to taste

Method

  1. Soak the peas overnight if possible (though split peas can be used without soaking — they'll just need longer cooking).
  2. Start the base. Place the split peas and pork knuckle (or bacon) in a large pot with the water or stock. Bring to a boil, skim any foam, then reduce to a gentle simmer.
  3. Add vegetables. After about 30 minutes, add the onion, celery, carrot, potato, and leek. Stir well.
  4. Simmer low and slow. Continue cooking on a low heat for 60–90 minutes, stirring occasionally, until the peas have broken down completely and the soup is thick and creamy.
  5. Add the rookworst. In the last 15 minutes, nestle the whole smoked sausage into the soup to warm through. Remove, slice, and stir back in.
  6. Season generously with salt and white pepper. Finish with chopped parsley.

Tips for the Perfect Erwtensoep

  • Day-old is better: Reheat the next day for deeper flavour — the peas continue to thicken overnight.
  • Consistency check: If it's too thick, add a splash of hot water. Too thin? Simmer uncovered for longer.
  • Vegetarian version: Skip the pork and rookworst, use vegetable stock, and add smoked paprika for depth. Finish with a drizzle of good olive oil.
  • Freezes beautifully — make a double batch and freeze in portions.

Serving Suggestions

Serve steaming hot in deep bowls with thick slices of roggebrood spread with butter. A small glass of Dutch jenever (gin) on the side is the traditional accompaniment — though any good bread and mustard work just as well.

Erwtensoep is more than a recipe — it's a ritual. Making it is an act of care, and sharing it is an act of warmth. That's the Dutch spirit at its best.
