Linsensuppe

Germany's smoky lentil soup: thick with Beluga lentils, root vegetables, and sliced Würstchen, finished with a dash of vinegar

Origin: Germany

From the journey of Lentils.

Linsensuppe is one of Germany's most deeply embedded winter dishes, with roots in medieval peasant cooking. It is eaten across Germany but is perhaps most beloved in Swabia (Baden-Württemberg), where it is traditionally served with Spätzle (egg noodles) rather than sausage. The Swabian version, Linsen mit Spätzle und Saitenwürste, is a regional dish of near-religious status. The characteristic German finish of a splash of red wine vinegar at the end echoes the Greek tradition of fakes soupa, both culinary cultures discovering independently that acid is the key that opens lentils' earthy depth.

Ingredients

Base

  • 350 g brown or Beluga lentils, rinsed
  • 1 litre good beef or chicken stock
  • 2 tbsp tomato paste

Meat

  • 200 g smoked Würstchen or frankfurters, sliced into rounds
  • 100 g smoked bacon lardons

Aromatics

  • 1 large onion, diced
  • 2 medium carrots, diced
  • 2 stalks celery, diced
  • 1 medium parsley root or parsnip, diced
  • 2 cloves garlic, minced

Herbs

  • 2 bay leaves
  • 4 sprigs fresh thyme

Spices

  • 1 tsp ground marjoram

For cooking

  • 2 tbsp neutral oil

Finish

  • 2 tbsp red wine vinegar or apple cider vinegar, to finish

Garnish

  • 2 tbsp flat-leaf parsley, chopped

Method

  1. Heat the oil in a large pot. Fry the bacon lardons over medium heat until the fat renders and they begin to crisp, about 4 minutes. Add the onion, carrots, celery, and parsley root. Cook for 8 minutes until softened.
  2. Add the garlic, tomato paste, marjoram, bay leaves, and thyme. Stir for 2 minutes.
  3. Add the lentils and stock. Bring to a boil, skim any foam, then reduce to a steady simmer. Cook for 30–35 minutes until the lentils are completely tender.
  4. Add the sliced Würstchen. Simmer for 5 minutes to warm the sausages through and allow them to flavour the soup.
  5. Remove the bay leaves and thyme sprigs. Season generously with salt, pepper, and the vinegar. The vinegar is essential; add it gradually and taste.
  6. Ladle into deep bowls. Scatter with parsley. Serve with dark rye bread or pumpernickel.

Notes

The Swabian version (Linsen mit Spätzle) omits the sausage in favour of Spätzle, small egg noodles added directly to the soup, and is considered the purer regional dish. Both versions finish with vinegar. Leftovers improve overnight as the lentils continue to absorb the smoky stock.
