Linsensuppe mit Würstchen (German Lentil Soup with Frankfurters)
Why this recipe works
- Hearty and sustaining: Lentils, root vegetables and frankfurters make the soup filling without needing a complicated method.
- Built-in depth: Leek, celeriac, carrot and smoked paprika create a savoury base before the lentils simmer into the stock.
- Bright finish: Red wine vinegar added at the end cuts through the richness and makes the lentils taste fuller.

Authenticity notes
- Home-style German soup: Linsensuppe is commonly served as a thick, practical lentil soup rather than a light broth, with vegetables cooked until they help enrich the base.
- With frankfurters: Adding Würstchen is a familiar variation that turns the soup into a complete meal while keeping the preparation simple.
Ingredient notes
- Use lentils that hold their shape: Green lentils are a good fit because they soften while still giving the soup some texture.
- Add vinegar at the end: Stirring in the vinegar after simmering preserves its brightness and lets you adjust the tang to taste.
- Dice the vegetables evenly: Small, even pieces of carrot and celeriac cook at the same pace and blend naturally into the thick soup.
Texture tips
- For a thicker soup: Mash a small portion of the cooked lentils against the side of the pot, then stir them back through the soup.
- Keep the sausages gentle: Once the frankfurters are added, keep the soup at a gentle simmer so they heat through without splitting.
Make-ahead tips
- Good for meal prep: The soup keeps well in the fridge and thickens as it sits; loosen it with a splash of water when reheating.
- Freeze without the frankfurters: For the best texture, freeze the lentil soup base on its own and add freshly warmed frankfurters when serving.
- Reheat gently: Warm the soup in a saucepan until piping hot, stirring occasionally so the lentils heat evenly.

Ingredients
Instructions
- Trim and rinse the leek well, then dice it. Peel and dice the carrots and celeriac into small, even pieces so they cook at the same rate.
- Heat the olive oil in a large pot over medium heat. Add the leek, carrots and celeriac with the smoked paprika, salt and pepper, then cook for 8 to 10 minutes, stirring, until the vegetables soften and smell sweet.
- Stir in the lentils and bay leaves, then pour in the vegetable stock. Bring to the boil, then reduce to a gentle simmer and cook for 45 to 55 minutes, stirring occasionally, until the lentils are tender and the soup is thick.
- Add the frankfurters and keep the soup at a gentle simmer for 5 to 7 minutes, just until the sausages are warmed through. Remove and discard the bay leaves.
- Stir in the red wine vinegar and taste, adjusting salt and pepper if needed. Ladle into bowls and finish with the parsley.
Recipe notes
Tips
- For a thicker, more traditional texture, lightly mash a ladleful of lentils against the side of the pot, then stir back in.
- Keep the soup at a gentle simmer once the frankfurters go in so they stay juicy rather than splitting.
- If serving to pregnant people, young children, older adults, or anyone immunocompromised, make sure the frankfurters are piping hot all the way through before serving.
Substitutions
- Replace red wine vinegar with apple cider vinegar for a slightly fruitier tang.
- Replace fresh parsley with fresh dill for a more herb-forward finish.
- Replace smoked paprika with sweet paprika for a milder, less smoky flavour.
Storage
- Refrigerate up to 3 days
- Cool quickly, then refrigerate in a sealed container. Reheat gently in a saucepan until piping hot, adding a splash of water if it has thickened; freeze without the frankfurters for best texture, then add freshly warmed frankfurters when serving.
