I grew up on the mayo-based potato salad that shows up at every cookout, and I still love it. But the first time I had German potato salad — warm, tangy, and glossy with bacon fat instead of mayonnaise — I understood why it has its own following.
It tastes like a potato salad that’s been to a barbecue and come back with more flavor.
This version rests on three things that separate a good German potato salad from a great one. Slice the potatoes before boiling, so they cook evenly and don’t crumble when you toss them.
Add the vinegar while the potatoes are still steaming, so the warm starch drinks it in and seasons them from the inside.
Whisk the dressing into the warm bacon fat off the heat until it emulsifies into a smooth, glossy vinaigrette instead of a greasy slick.
I’ve made this on different occasions, and the detail that matters most is the double mustard — whole-grain for texture and Dijon for the emulsion. The Dijon is what stabilizes the bacon fat and vinegar into a dressing that clings to the potatoes instead of pooling at the bottom of the bowl.
It’s a tablespoon, and it’s the difference between a salad that looks like the photo and one that looks like potatoes in grease.
Why This Recipe Works
Slicing the potatoes before boiling is what keeps them intact. Whole baby potatoes are boiled and then sliced; the warm crumble at the edges turns to mash. Cut into uniform half-inch pieces before they hit the water; they cook evenly and hold their shape through the toss. The cut sides also absorb more of the vinegar.
Pouring two tablespoons of cider vinegar over the hot, drained potatoes seasons them from the inside out. Warm starch absorbs liquid, and the vinegar soaks into the potatoes as they cool. If you wait and add all the vinegar to the dressing, it sits on the surface instead of penetrating, and the salad tastes sharp on the outside and bland in the middle.
The double mustard — whole-grain plus Dijon — is what makes the vinaigrette emulsify. Whole-grain mustard gives you texture and a sharp, seedy bite. Dijon is finer and acts as an emulsifier, binding the bacon fat and vinegar into a smooth, creamy dressing. Without one, you get either a grainy dressing or a thin one.
Whisking the dressing off the heat is what keeps it glossy instead of broken. Bacon fat and vinegar separate if you add them together over high heat. Turning the heat to low, adding a splash of warm water, and whisking vigorously for a minute is what brings the fat and liquid together into a stable emulsion. If it looks greasy, it wasn’t whisked enough.
A tablespoon of brown sugar balances the vinegar without making the dressing sweet. German potato salad is tangy, not sugary. The sugar rounds off the sharp edges of the cider vinegar, and a tablespoon is enough without turning the dressing into a glaze.
Fresh parsley and chives go in at the very end, off the heat. They stay bright green and fresh, and they give the salad a herbal note that cuts through the bacon. If you add them earlier, they wilt and turn dark.
The point is to serve it warm or at room temperature. German potato salad isn’t a cold salad. Warm, the vinegar is sharper, and the bacon fat is liquid and glossy. At room temperature, the flavors meld, and the dressing thickens slightly. Either way, it’s better than cold.
Ingredients That Matter
Most of this list is flexible. Three ingredients are easy to get wrong, so those are the ones worth explaining.
Small red potatoes, cut into half-inch pieces before boiling. Red potatoes hold their shape better than russets and have thin skins that don’t need peeling. Cut them into uniform pieces so they cook at the same rate — uneven pieces mean some crumble while others stay firm.
Apple cider vinegar, divided. Add two tablespoons to the hot potatoes, and the rest to the dressing. Cider vinegar is the traditional choice — it’s sharper and fruitier than white vinegar, and it’s what gives the salad its tang. White vinegar works in a pinch but tastes flatter.
Use whole-grain mustard and Dijon mustard together. The whole-grain brings texture and a seedy bite; the Dijon brings the emulsifying power that holds the dressing together. Don’t substitute one for the other — they do different jobs.
How to Make It
Step 1: Boil and season the potatoes.
Place 3 pounds of red potatoes, cut into ½-inch pieces, in a large pot and cover with cold water by 1 inch. Add 1 tablespoon kosher salt, bring to a boil, then reduce heat to medium and simmer 10 to 12 minutes, until tender when pierced with a fork. Drain thoroughly, return the potatoes to the warm pot, and immediately drizzle with 2 tablespoons of the apple cider vinegar. Gently toss and cover to keep warm.
Step 2: Crisp the bacon.
Cook 8 ounces of chopped bacon in a large skillet over medium heat for 6 to 8 minutes, stirring occasionally, until deeply golden and crispy. Transfer the bacon to a paper towel-lined plate with a slotted spoon, leaving the rendered fat in the skillet.
Step 3: Sauté the onions.
Reduce the heat to medium. Add 1 finely chopped yellow onion and 1 teaspoon of salt to the warm bacon fat. Sauté for 4 to 5 minutes, until soft, translucent, and lightly golden.
Step 4: Emulsify the vinaigrette.
Turn the heat to low. Whisk in the remaining apple cider vinegar, 2 tablespoons whole-grain mustard, 1 tablespoon Dijon mustard, 1 tablespoon brown sugar, ½ teaspoon black pepper, and 2 tablespoons warm water. Whisk vigorously for 1 minute, until the bacon fat and liquids emulsify into a smooth, glossy dressing. Remove from the heat.
Step 5: Toss and serve.
Pour the warm dressing over the warm potatoes. Add the crispy bacon and toss gently with a rubber spatula until every potato is coated. Fold in ½ cup of finely chopped flat-leaf parsley and 2 tablespoons of fresh chives. Taste and add salt if needed. Serve warm or at room temperature.
Tips and Troubleshooting
The potatoes crumbled when I tossed them. They were boiled whole and sliced warm, or they were overcooked. Cut them before boiling, cook until just tender, and toss gently with a spatula rather than a spoon.
The dressing looks greasy and separated. You didn’t whisk it enough, or the heat was too high. Turn the heat to low, add a splash of warm water, and whisk vigorously until it comes together. If it’s already on the potatoes, a tablespoon of Dijon and a hard stir can pull it back.
The salad tastes too sharp. The vinegar was stronger than expected, or you left out the sugar. Add a pinch more brown sugar and taste. German potato salad should be tangy, not sour.
The salad tastes flat. It needs salt. Taste the dressing before it goes on the potatoes and add salt if needed — the potatoes absorb a lot.
The bacon is soggy. It was cooked at too low a heat or crowded in the pan. Cook it in a single layer over medium heat and stir occasionally until it’s deeply golden.
The herbs turned dark. They went in too early or the heat was too high. Fold them in at the very end, off the heat.
The salad is dry the next day. The potatoes absorb the dressing as it sits. Reheat gently with a splash of water or a little extra vinegar and oil, or serve it at room temperature with a drizzle of olive oil.
Storage and Make-Ahead
Store the salad in a sealed container in the refrigerator for up to 3 days. It’s best warm or at room temperature on the day it’s made, and the flavor deepens overnight as the potatoes absorb the dressing.
To make it ahead, boil the potatoes and cook the bacon and onions up to a day in advance and store them separately in the refrigerator. Make the dressing and toss everything together right before serving so the herbs stay bright.
I don’t recommend freezing this salad. The potatoes turn watery, and the texture breaks down.
Store leftovers in the refrigerator within 2 hours of serving, and discard anything left at room temperature for more than 2 hours — this salad has bacon and a warm dressing, so the two-hour rule matters.

FAQ
Can I make this potato salad ahead of time?
Yes. Boil the potatoes, cook the bacon, and sauté the onions up to a day ahead, then store each separately in the refrigerator. Make the dressing and toss everything together right before serving so the herbs stay bright.
What kind of potatoes work best?
Small red potatoes are the traditional choice because they hold their shape and have thin skins. Yukon Gold works too but is a little softer. Avoid russets, which fall apart.
Can I use white vinegar instead of apple cider vinegar?
Yes, but cider vinegar is sharper and fruitier and gives the salad its traditional flavor. White vinegar works in a pinch but tastes flatter.
Is this German potato salad served warm or cold?
Warm or at room temperature. It’s not a cold salad — the dressing is liquid and glossy when warm, and it thickens slightly as it cools. Both ways are good.
Can I make this without bacon?
You can, but the bacon fat is the base of the dressing. If you skip it, use 3 tablespoons of olive oil instead and add a pinch of smoked paprika for depth. The flavor will be different but still good.
What do you serve with German potato salad?
It’s a classic side for bratwurst, grilled sausages, schnitzel, and anything off the grill. It also works with roasted chicken or a simple sandwich.
