German White Bean and Onion Salad Weisser Bohnensalat Recipe
This simple salad of white beans, onion and a herby vinegar dressing is popular in southern Germany as a side dish for grilled sausages and roasted meats. It is filling yet light, because instead of mayonnaise it has a winey, herb-infused dressing. It’s a bit like an Italian bean salad, but with a more pronounced vinegary note and a German character thanks to the addition of mustard.
Such tangy bean salads are typical of the southern German states, where they’re often served with sausages and cold cuts as part of a “Brotzeit”. They often appear on beer-hall buffets alongside potato salad and pickled cucumbers.
This salad combines pantry staples into a flavourful German-style side that works year-round. The tangy mustard-vinegar dressing cuts through the creaminess of the beans, making it both satisfying and refreshing.
Why this version works
- Canned beans cut down the prep time without compromising texture, as long as you drain them well.
- Soaking sharp onion softens its bite while keeping a pleasant crunch.
- A simple vinegar-and-mustard dressing is easy to adjust to your preferred level of acidity.
Chef's tips
Don’t skip the resting time – it allows the beans to absorb the dressing and makes a big difference to the final taste. If you cook the beans yourself, leave them slightly firm so they hold their shape in the salad.
How to serve
Serve slightly chilled or at room temperature alongside grilled meats, sausages or roasted vegetables. It also packs well in lunch boxes and is great for picnics or potlucks.
Watch out for
- Beans that are too wet will thin the dressing and make the salad watery.
- If you add a lot of salt before the salad has rested, it may end up too salty after it sits – it’s better to finish salting at the end.
Substitutions
- Instead of red onion you can use white onion or shallots for a milder flavour.
- Replace some of the dill pickles with sweet-and-sour gherkins if you prefer a gentler acidity.
- You can swap white wine vinegar for apple cider vinegar if you want a fruitier note.
Ingredients
- white beans cooked or from a can, drained - 400 g
- red onion small to medium - 1 piece
- pickled cucumber medium - 2 piece
- parsley leaves chopped - 3 tablespoons
- white wine vinegar - 3 tablespoons
- vegetable oil e.g. rapeseed or sunflower - 4 tablespoons
- mustard mild or medium hot - 1 teaspoon
- sugar to balance the flavour - 0.5 teaspoons
- salt to taste
- black pepper freshly ground, to taste
Preparation
- If using canned beans, drain them in a sieve and rinse very thoroughly under cold water until they no longer foam. Leave them in the sieve for at least 5 minutes, until the droplets stop running off – the beans should be moist but with no visible brine.
- Peel the onion and cut it into very thin slices or a fine dice. If it’s very sharp, cover it with cold water for 5 minutes or sprinkle lightly with salt, then squeeze it out – it should stay crunchy but taste milder.
- Cut the dill pickles into a fine dice so their flavour is evenly distributed throughout the salad. Chop the parsley not too finely so you still see small green leaves in the finished dish.
- In a small bowl, prepare the dressing: mix the wine vinegar, oil, mustard, sugar, salt and pepper. Whisk vigorously until the dressing is homogeneous, slightly thicker, and without streaks of oil on the surface.
- Put the well‑drained beans into a large bowl, add the onion, pickles and most of the parsley. Gently mix with a wide spoon, lifting the ingredients from the bottom – the beans should stay whole, without crushed skins.
- Pour the dressing over the salad and again mix very gently until every bean is lightly coated in the sauce. A thin layer of dressing may collect at the bottom of the bowl, but the salad should not be swimming in it.
- Let the salad rest for at least 20–30 minutes at room temperature or in the fridge so the flavours can meld. After this time the beans will be more aromatic and the vinegar smell will be less sharp and pleasantly winey.
- Before serving, taste the salad and, if necessary, adjust with more salt, pepper, or a few drops of vinegar if you like a stronger tang. Sprinkle with the reserved parsley so the top looks fresh and green.
Storage
Store leftover salad covered in the fridge for up to 2–3 days. The flavours will deepen over time; just refresh with a little extra oil and vinegar before serving if needed.
I often double the dressing and keep some in a jar – it’s perfect not only for this salad but also for quick green salads or potato salads. A small spoonful of mustard really gives the beans a pleasant, savoury kick.
