German potato salad made with mayonnaise, cider vinegar, green bell pepper, and onion is a creamy, tangy side that comes together in about 35 minutes. The vinegar cuts through the mayo so it never tastes heavy. It serves two generously, and it works alongside grilled meat, sandwiches, or just on its own.
Why this recipe works
Two things carry this salad. First, the cider vinegar goes into the dressing before the potatoes arrive โ that means the mayo is already seasoned and slightly loosened, so it coats the potato cubes evenly instead of clumping. Second, letting the potatoes cool completely before you cut and mix them is what keeps the salad from turning to mush. Hot potatoes absorb dressing unevenly and break apart under a spoon. Give them real time to cool โ 20 to 30 minutes on the counter โ and they hold their shape when you fold everything together.
What can go wrong
- Potatoes fall apart in the bowl. This usually means they were overcooked or still warm when mixed. Check them at 20 minutes by piercing with a fork โ you want tender, not crumbling. Drain immediately and spread them out so steam escapes fast.
- The dressing tastes flat. Onion salt and black pepper do the heavy lifting here, so measure carefully rather than eyeballing. Taste the dressing before the potatoes go in and adjust โ it should taste slightly too sharp on its own, because the potatoes will mellow it out.
- The bell pepper releases water and thins the dressing. Cut the pepper into small, uniform pieces and pat them dry with a paper towel before mixing. Excess surface moisture is what dilutes a mayo-based dressing.
- Everything sticks to the bottom of the bowl. Use a bowl that is bigger than you think you need. A cramped bowl makes folding difficult and breaks up the potato cubes. Fold gently with a large spoon or spatula rather than stirring in circles.
- The celery seed flavor disappears. Celery seed is subtle and can get lost if added too late. Mix it into the dressing with the vinegar and onion salt so it has time to bloom before the potatoes are added.
Storage and make-ahead
Store the finished salad in an airtight container in the refrigerator for up to three days. The flavors actually improve after a few hours as the vinegar and onion salt work into the potatoes, so making it the morning before you need it is a genuinely good idea. That said, dress it at the table if you are serving it at a gathering โ a pre-dressed salad that sits out for more than an hour goes limp and the mayo can separate. If you want to prep ahead, keep the dressing and the chopped vegetables in one container and the cooled, cubed potatoes in a separate one, then combine up to an hour before serving. Give it a gentle stir and taste for seasoning before it goes out, since chilled food often needs a small extra pinch of salt.

FAQ
Do I need to peel the potatoes before boiling?
No, you can boil them with the skin on and peel after cooling if you prefer โ the skin actually helps them hold together during cooking. Once cooled, the skin slips off easily with your fingers, or you can leave it on for extra texture.
What kind of potatoes work best here?
Waxy potatoes like Yukon Gold or red potatoes hold their shape after boiling and cubing. Russets are starchier and tend to crumble when mixed, which gives you a rougher, less defined salad.
Can I make this for more than two people?
Yes โ the recipe card has a 2x and 3x scaling option built in. Keep in mind that a larger batch of potatoes will take closer to the full 30 minutes to cook through, so check them a few minutes earlier and go by feel rather than the clock.
Is there anything I can substitute for mayonnaise?
A full swap for plain Greek yogurt works if you want something lighter, though the flavor will be tangier and less rich. You can also do half mayo and half Greek yogurt to keep the creaminess while cutting some of the fat.
