German potato salad skips the mayo entirely. The dressing here is built from bacon fat, apple cider vinegar, Dijon, and whole grain mustard โ it soaks into warm Yukon Gold slices and turns a simple side into something genuinely filling. Forty-five minutes start to finish, one skillet for the dressing, and it feeds four.
Shopping notes
- Yukon Gold potatoes: Worth seeking out specifically. Red potatoes are an acceptable swap โ they hold their shape similarly. Russets will fall apart when you fold in the dressing.
- Whole grain mustard: Adds texture and a slightly milder bite alongside the Dijon. If you only have Dijon, use 2 tablespoons total โ the salad will still work, just with a smoother, sharper edge.
- Thick-cut bacon: Regular bacon renders less fat and produces smaller, less satisfying pieces. Stick with thick-cut if you can.
- Apple cider vinegar: White wine vinegar is the closest swap. Plain white vinegar is sharper and can overpower โ use a little less if thatโs all you have.
Before you start
Two things determine whether this salad is good or just fine. First, donโt overcook the potatoes โ pull them the moment a fork slides in with light resistance, around 10 minutes. Overcooked slices turn to mash when you fold in the dressing. Second, add the potatoes to the skillet while theyโre still hot. Hot potatoes absorb the vinegar-mustard dressing; cool potatoes sit on top of it. Drain them, let the steam escape for a minute, then go straight into the pan โ dress it at the table if youโre serving a crowd, but for this recipe, folding everything together while warm is exactly the point.
If something goes sideways
- Dressing tastes too sharp: The vinegar can dominate if the sugar didnโt fully dissolve. Add a pinch more sugar and stir over low heat for another minute before adding the potatoes.
- Potatoes are falling apart: They were cooked too long or cut too thin. Next time, aim for a true half-inch slice and start checking at 9 minutes. For now, serve it as-is โ the texture is softer but the flavor is still there.
- Not enough dressing to coat everything: This happens when the bacon rendered less than 2 tablespoons of fat. Add a tablespoon of olive oil to the skillet to make up the difference, then re-whisk the dressing before adding the potatoes.
- Salad tastes flat: Vinegar-based dressings need adequate salt to come alive. Taste after folding and add salt in small increments โ the bacon contributes some, but itโs rarely enough on its own.
- Bacon turned chewy instead of crispy: The pan was too crowded or the heat too low. Spread pieces in a single layer and give them space. If itโs already done, a quick minute in a dry skillet over medium-high heat can crisp them back up before you add them in.
Keeping leftovers crisp
Store leftovers in an airtight container in the refrigerator for up to three days. The potatoes will absorb more dressing as they sit, so the salad gets denser and more intensely flavored by day two โ thatโs not a bad thing. Reheat gently in a skillet over low heat with a splash of apple cider vinegar to loosen it up, or eat it at room temperature straight from the fridge. The parsley wilts and discolors overnight, so hold it back and add fresh parsley only to the portion youโre serving immediately. Thereโs nothing crisp to protect here the way there would be with greens, but the bacon does soften in storage โ if that bothers you, keep a few extra strips separate and add them when you reheat.
German Mustard Potato Salad
Equipment
- Large pot
- Colander
- Mixing bowl
- Whisk
- Large skillet
- Wooden spoon
Ingredients
- 2 lbs Yukon Gold potatoes Scrubbed and cut into ยฝ-inch slices
- 6 slices thick-cut bacon chopped
- 1 small yellow onion finely diced
- โ cup apple cider vinegar
- 1 tbsp Dijon mustard
- 1 tbsp whole grain mustard
- 1 tbsp granulated sugar
- ยฝ tsp salt adjust to taste
- ยฝ tsp black pepper freshly ground
- ยผ cup chopped fresh parsley for garnish
Instructions
- Place the sliced potatoes in a large pot and cover them with cold salted water. Bring to a boil over medium-high heat and cook until just fork-tender, about 10-12 minutes. Drain and set aside.
- In a large skillet over medium heat, cook the chopped bacon until crispy, about 6-8 minutes. Transfer to a paper towel-lined plate, leaving about 2 tablespoons of bacon fat in the skillet.
- Reduce heat to medium-low and sautรฉ the diced onion in the bacon fat until soft and translucent, about 3-4 minutes.
- Whisk in the apple cider vinegar, Dijon mustard, whole grain mustard, sugar, salt, and black pepper. Let simmer for 1-2 minutes, stirring frequently.
- Add the drained potatoes and crispy bacon back into the skillet. Gently fold them into the dressing, letting the potatoes absorb the flavors for 2-3 minutes.
- Remove from heat and sprinkle with fresh parsley before serving warm.
Notes
- For an extra punch of flavor, let the salad rest for 10 minutes before serving to allow the ingredients to meld together.

Frequently asked questions
Can I make this ahead for a party?
Yes, but serve it warm or at room temperature rather than cold from the fridge. Make it up to two hours ahead, keep it covered in the skillet, and reheat gently over low heat with a small splash of vinegar just before serving.
Is there a way to make this without bacon?
You can, but youโll need to replace the bacon fat with olive oil โ about 2 tablespoons. The smoky depth will be missing, so add half a teaspoon of smoked paprika to the dressing to compensate.
How do I keep the potatoes from turning mushy when I fold everything together?
Use a wide spatula and fold gently rather than stirring. Cutting the potatoes to a consistent half-inch thickness also helps โ thinner slices break down faster under heat.
What do I serve this with to make it a full meal?
A couple of bratwurst or a pan-seared pork chop alongside a portion of this salad is genuinely filling. The bacon and potatoes together have enough substance that you donโt need much else on the plate.
Can I use a different vinegar?
White wine vinegar is the best substitute โ similar acidity, clean flavor. Red wine vinegar works too but adds a slightly more robust bite. Avoid balsamic, which is too sweet and will throw off the balance of the dressing.
My dressing separated in the pan โ is it ruined?
No, just whisk it again over low heat for 30 seconds before adding the potatoes. Fat-and-vinegar dressings donโt emulsify the way mayo-based ones do, so some separation is normal.
