Erwtensoep (Dutch Split Pea Soup)

Thick, savoury and unmistakably Dutch, erwtensoep is split pea soup treated as a substantial meal rather than a light starter. The peas are simmered until they collapse into a dense, spoon-coating base, enriched here with tender pork shoulder, bay, celeriac, carrot and leek. Slices of fully cooked smoked sausage are warmed through at the end, adding the smoky, salty depth that makes the soup so recognisable. It is practical cold-weather cooking: economical, filling and even better once the flavours have had time to settle, though it should be loosened gently when reheated as it thickens in the fridge.

Why this recipe works

  • Naturally thick texture: Split peas break down as they simmer, creating a dense, creamy soup without needing cream or a separate thickener.
  • Deep savoury flavour: Pork, bay leaves, root vegetables, leek and smoked sausage build a rounded flavour with both sweetness and smoke.
  • Improves as it stands: The soup thickens and the flavours settle after chilling, making it well suited to cooking ahead and reheating gently.

Authenticity notes

  • Cooked until very thick: Erwtensoep is recognisable for its dense, almost stew-like consistency rather than a thin broth.
  • Smoked sausage finish: Fully cooked smoked sausage is usually added near the end so it warms through while keeping its texture.
  • Traditional serving: Rye bread is a classic accompaniment, especially when the soup is served as a hearty main meal.

Texture tips

  • For a thicker soup: Let the peas simmer until they collapse fully, stirring often as the base becomes heavier.
  • For a looser consistency: Add a little hot stock while reheating or near the end of cooking, then adjust the seasoning to taste.
  • For a smoother finish: Mash some of the soup against the side of the pot and stir it back in, leaving some vegetables intact for texture.

Common mistakes

  • Simmer gently: A hard boil can make the thickening peas catch on the bottom of the pot, so keep the heat low once they start breaking down.
  • Do not stop too early: The peas should be soft enough to lose their shape; if they remain firm, the soup will taste thinner and less integrated.
  • Add the sausage at the end: The smoked sausage is already cooked, so it only needs enough time in the soup to become piping hot.

Make-ahead tips

  • Good the next day: Chilling allows the soup to thicken further and gives the savoury flavours time to settle.
  • Reheat gently: Warm over a low heat, stirring regularly and loosening with a splash of stock if the soup has become too thick.
  • Freezes well: Cool quickly, freeze in portions, then thaw and reheat until piping hot throughout.

  1. Cut the pork shoulder into large chunks. Rinse the split peas in a sieve-strainer under cold water until the water runs mostly clear.
  2. Put the pork, split peas, vegetable stock, bay leaves, fine sea salt and black pepper into a stockpot. Bring to the boil, then reduce to a gentle simmer and skim off any foam.
  3. Simmer gently for 60 minutes, stirring now and then, until the peas are breaking down and the pork is tender. If it starts to catch, lower the heat and stir more often.
  4. Meanwhile, peel the celeriac and cut it into small dice. Peel the carrot and slice it, then wash the leek well and slice it.
  5. Stir the celeriac and carrot into the pot. Simmer for 20 minutes until the vegetables are tender and the soup is thick and spoon-coating.
  6. Add the leek and simmer for 10 minutes until softened. Remove and discard the bay leaves, then taste and adjust with a little more fine sea salt and black pepper if needed.
  7. Slice the smoked sausage and stir it into the soup. Warm through for 5 minutes until piping hot, then ladle into bowls.

Recipe notes

Tips

  • Keep the simmer gentle and stir regularly once the peas start to break down, as the soup can catch on the bottom.
  • If you prefer a smoother texture, mash a portion of the soup against the side of the pot with a wooden spoon, then stir back in.
  • If serving vulnerable groups, make sure the smoked sausage is heated until piping hot throughout.

Substitutions

  • Replace Pork shoulder with Pork belly for a richer, more traditional-style soup.
  • Replace Vegetable stock with Chicken stock for a deeper savoury base.
  • Replace Smoked sausage with Smoked turkey for a lighter, less fatty finish.

Storage

  • Refrigerate up to 3 days
  • Cool quickly, then refrigerate in a sealed container. The soup will thicken as it stands; loosen with a splash of vegetable stock when reheating, and heat gently on the hob until piping hot.
