Real German Potato Salad

A cold German-style potato salad known as Kartoffelsalat in the northern and western regions of Germany, distinct from the warm, bacon-and-vinegar southern version most Americans recognize as “German potato salad." Diced apple is the signature addition that separates this from American potato salad. It brings a cool, slightly tart crunch that cuts the richness of the dressing.

The dressing itself is simple: mayonnaise, dill relish, and prepared mustard, with hard-boiled eggs stirred in for extra substance. Mustard is the flavor anchor. German mustard (a stronger, spicier variety than American yellow) works best, but any prepared mustard will do in a pinch.

The overnight rest in the fridge is non-negotiable. At least two hours, but ideally 12 to 24 in the cold, gives the potatoes time to absorb the dressing and for flavors to meld. Freshly mixed German potato salad tastes harsh and separate; rested salad tastes cohesive and creamy, with every component playing its part.

Kitchen Tips

• Use waxy potatoes (Yukon Gold, red, or fingerling) instead of russets. Waxy potatoes hold shape when sliced; russets fall apart into mush.
• Slice potatoes while still warm, not hot. Warm potatoes absorb the dressing better; hot ones make the mayo greasy.
• Use sweet-tart apples like Granny Smith, Honeycrisp, or Gala. Soft baking apples turn to mush in the salad.
• Season generously with salt. Cold salads need more salt than warm dishes; the cold mutes flavors and you’ll need more than you think.

Variations

• Swap dill relish for chopped cornichons or capers for a more refined bite.
• Add crumbled crisp bacon or diced ham for a heartier version.
• Finish with chopped fresh dill or chives just before serving for herbal brightness.
