German potato salad is dressed with hot bacon fat, cider vinegar and onion instead of mayonnaise. It is served warm or at room temperature, never chilled, because warm potatoes absorb the vinegar dressing and cold bacon fat turns waxy. It takes about 45 minutes and it is better after resting half an hour.

Long weekend coming, and somebody is going to bring potato salad.
Make this one instead. It takes the same amount of work, it holds up better on a table outdoors, and it comes with a story that is a good deal more interesting than the creamy bowl beside it.
This is the older recipe. German immigrants were making it in American kitchens by the mid-nineteenth century, decades before anyone bought mayonnaise in a jar. The full recipe is in the card at the bottom. What follows is everything the card does not have room for.
What makes it different from American potato salad
One choice, and everything else follows from it.
American potato salad is bound with mayonnaise. That makes it rich, mild and slightly sweet, and it has to be served cold. German potato salad is dressed with vinegar and fat. That makes it sharp, savory and salty, and it wants to be warm.
The two versions even take opposite instructions. Mayonnaise needs the potatoes cool or the sauce splits. Vinegar needs them hot, or the dressing never gets in. Same vegetable, opposite recipe.
Which Germany does this come from
Worth knowing, because Germany does not agree with itself here.
In Swabia and much of the southwest, Kartoffelsalat is made with oil, vinegar and often a little warm broth. No bacon anywhere near it. It is served at room temperature and turns almost creamy from the potato starch, not from anything you add.
The version with hot bacon fat and onion belongs further north and east. That is the one German immigrants brought to America, and it is what North Americans mean when they say German potato salad.
If a German tells you this isn’t authentic, they are probably Swabian. They are also not entirely wrong.
Why the American version has mayonnaise at all
The vinegar version came first here, and it went wherever German communities went. Beer gardens, church suppers, union picnics.
It was on the tables at the first Labor Day, which was a beer garden picnic in New York in September 1882. That’s why I went looking for this recipe in the first place.
In 1882, mayonnaise was a restaurant sauce. Made by hand, unstable, and not something you built a picnic bowl around. Commercially bottled mayonnaise did not reach American grocery shelves until the early twentieth century. When it did, it was cheap, shelf-stable, and effortless, and the creamy version took over so completely that the older one had to be renamed after the people who brought it.
So the traditional potato salad most of us grew up on is the newer one. This is the original.
What actually matters when you shop
Four things, and only one of them is worth being fussy about.
Potatoes. Buy waxy ones, red or Yukon Gold. They hold their shape when you slice them hot and fold them through dressing. Russets and other floury bakers collapse and you end up with warm mash. This substitution ruins the dish, and it is the only one I would call a rule.
Vinegar. Cider vinegar is softer and reads a little sweet against the bacon. White is sharper and perfectly traditional. Use what is in the cupboard.
Bacon. Thick cut gives you something to bite. Thin cut disappears into the salad. Both work.
And do not pour away all the potato water. Save half a cup for the dressing. It carries starch, and the starch is what gives the dressing enough body to cling to the potatoes instead of pooling in the bottom of the bowl. It costs nothing, and most recipes never mention it.
The one step that decides whether it works
Hot dressing on warm potatoes. That is the whole technique.
A warm potato is still open. Its starch is swollen with water, and it pulls the vinegar dressing straight in, all the way through the slice. A cold potato has firmed up and closed, so the dressing slides off and settles at the bottom. You will taste the difference immediately, and adding more dressing does not fix it.
This is why the recipe has you peel potatoes while they are still too hot to hold comfortably. Use a folded tea towel and a paring knife and accept a bit of discomfort. Three minutes of inconvenience for the dish’s entire point.
It is also why this salad should never go in the fridge before serving. Cold bacon fat is not a texture anyone enjoys.
Does skipping the mayonnaise make it safe to leave out?
No, and I want to be straight about this because plenty of recipe sites suggest otherwise. I believed it myself for years.
The idea that mayonnaise is the dangerous part of potato salad is a myth. Commercial mayonnaise is made with pasteurized eggs and carries enough vinegar and lemon juice to be genuinely acidic. Food scientists have found that pathogens introduced into it tend to die rather than multiply, and researchers at the University of Georgia found commercial mayonnaise actually reduced Salmonella in meat salads.
The risk in potato salad is the potato. Cooked potatoes are low in acid and perfectly comfortable for bacteria. The usual culprits in outbreaks are Staphylococcus aureus and Clostridium perfringens, introduced by hands and then given time at the wrong temperature.
So the rule is the same for both bowls. Two hours out, or one hour if it is above 90F, then it goes in the fridge.
This version doesn’t give you safety. The dish is designed to be eaten warm or at room temperature, so it is at its best during exactly the window when it is safe to sit out. The creamy one is best cold and gets worse every minute it sits on the table. That is a real advantage. It is just not the one people think they are getting.
What to put it next to
Bratwurst and sausages, which is the traditional pairing and still the best one. Roast pork. Pork chops. Smoked ham. Grilled chicken. Anything off a barbecue that needs something sharp beside it.
If you want the full 1880s beer garden table, add rye bread, a jar of sharp mustard, good pickles and a cold lager. That is more or less what New Yorkers were eating on the day this recipe came from.
Making it ahead
- Best made three or four hours before serving and left covered on the counter. The resting is not optional; it is when the potatoes take up the dressing.
- Keeps three to four days in the fridge in an airtight container.
- Bring refrigerated leftovers back to room temperature for at least half an hour, or warm them gently in a low oven. Never serve it cold.
- Add fresh parsley when you revive leftovers. It goes drab overnight.
- Freezing works, but the potatoes soften. Only worth doing if you will serve it warm.
Frequently asked questions
Is German potato salad served hot or cold?
Warm or at room temperature, never chilled. The vinegar dressing needs warm potatoes to soak in properly, and the bacon fat turns waxy in the fridge. Make it a few hours ahead, leave it covered on the counter, and add fresh parsley before serving.
Why does German potato salad have no mayonnaise?
Because it predates convenient mayonnaise. German cooks dressed potatoes with vinegar, fat and onion long before bottled mayonnaise reached American shelves in the early twentieth century. The creamy American version came after, and the older style kept the name of the people who brought it.
What potatoes are best for German potato salad?
Waxy potatoes such as red potatoes or Yukon Gold. They hold their shape when sliced hot and folded through dressing. Avoid russets and other floury baking potatoes, which break down and turn the salad to mash. This substitution is most likely to ruin the dish.
Can you make German potato salad ahead of time?
Yes, and it is better for it. Make it three to four hours before serving and leave it covered at room temperature so the potatoes absorb the dressing. If you make it the day before, refrigerate it and bring it back to room temperature for at least 30 minutes before serving.
Is potato salad without mayonnaise safer to leave out?
No. Mayonnaise is not the risky ingredient; commercial mayonnaise is acidic enough to suppress bacteria. The potatoes are the risk in either version. The USDA rule applies to both: keep it out for 2 hours at room temperature, or 1 hour above 90F, then refrigerate.
Can I make German potato salad without bacon?
Yes. Use three tablespoons of butter or olive oil instead of the bacon fat, and add a teaspoon of smoked paprika to replace the smokiness. The Swabian version uses no bacon at all and is entirely traditional.
What is the difference between German and American potato salad?
German potato salad is dressed with vinegar, fat and onion and served warm, giving a sharp and savory result. American potato salad is bound with mayonnaise and served cold, giving a rich, mild result. The dressing choice also reverses the method: one wants hot potatoes, the other cool.
A final thought
This is a hundred and forty-year-old picnic dish that solves a modern problem: half the table avoids mayonnaise, and the other half worries about the cooler.
It also happens to be what people were eating in a New York beer garden on the afternoon that turned into Labor Day. If you want that story, with the parade, the kegs and the man who nearly cancelled the whole thing before breakfast, it is here.
Make it in the morning. Leave it on the counter. Enjoy your weekend.
German Potato Salad Without Mayonnaise
Ingredients
- 2 lb 900 g waxy potatoes, such as red or Yukon Gold, scrubbed but not peeled
- 6 slices thick cut bacon chopped
- 1 medium medium onion finely chopped
- 1/4 cup 60 ml cider vinegar
- 1/2 cup 120 ml hot potato cooking water
- 1 tbsp sugar
- 1 tsp dry mustard
- 1 tsp salt plus more to taste
- Black pepper generously
- 3 tbsp chopped parsley
Instructions
- Boil the potatoes whole in salted water until a knife slides in with no resistance, about 20 to 25 minutes. Reserve half a cup of the cooking water before you drain them.
- Peel the potatoes while they are still hot. The skins come away with a paring knife and a tea towel. Slice them about a quarter inch thick into a wide bowl.
- Fry the bacon in a heavy pan until crisp. Lift it out and set it aside, leaving the fat behind.
- Cook the onion in the bacon fat over medium heat until soft and just golden, about five minutes.
- Add the vinegar, the reserved potato water, the sugar, the dry mustard, the salt and plenty of pepper. Bring it to a simmer and let it bubble for one minute.
- Pour the hot dressing over the warm potatoes. Add the bacon and parsley and fold it through gently. Warm potatoes drink the dressing. Cold ones do not, which is why timing matters more than technique here.
- Let it sit at least 30 minutes before serving. Taste again at the end. It will want more salt and more pepper than you expect.
Notes
Sharper: swap a tablespoon of the vinegar for pickle brine.
Make ahead: holds two days in the fridge. Bring it back to room temperature and add fresh parsley before serving.
Serve it with cold ham, rye bread, sharp mustard and a lager. That is the Elm Park table, more or less.
