Authentic German Potato Salad (Schwäbischer Kartoffelsalat)
This authentic German potato salad recipe known as Schwäbischer Kartoffelsalat is what you will find served in restaurants throughout the country and is made with broth, vinegar, oil, and a dash of mustard and sugar. This remains my favorite potato salad and is made just the way my Mutti and Oma always made it!
Servings: 6
Ingredients
- 3 lb small firm yellow-fleshed waxy potatoes (e.g. Yukon Gold) of similar size, skins scrubbed and peels left on
- 1 medium yellow onion chopped
- 1½ cups water, mixed with 4 teaspoons beef bouillon granules (Vegans: use vegetable bouillon)
- ½ cup white vinegar
- A few splashes of Essig Ezzenz (highly recommended for the best, authentic flavor)
- ¾ Tbsp salt
- ½ tsp freshly ground white pepper
- 1 tsp sugar
- 2 tsp mild German mustard If you can't get it, use regular yellow mustard
- ⅓ cup neutral-tasting oil
- Fresh chopped chives for garnish
Instructions
- Boil the potatoes in their skins in lightly salted water until tender. Allow the potatoes to cool until you can handle them. Peel the potatoes and slice them into 1/4 inch slices. Put the sliced potatoes in a large mixing bowl and set aside.
- Add onions, beef broth, vinegar, salt, pepper, sugar, and mustard in a medium saucepan and bring to a boil. As soon as it boils, remove from heat and pour the mixture over the potatoes. Cover the bowl of potatoes and let sit for at least one hour.
- After at least one hour, gently stir in the oil and season with salt and pepper to taste. If too much liquid remains, use a slotted spoon to serve. Serve garnished with fresh chopped chives. Serve at room temperature. Note: This potato salad is best the next day (remove from fridge at least 30 minutes before serving).
Notes
Key German Potato Salad Ingredients
The ingredients in a traditional Swabian potato salad recipe are few and simple, but there are a few tricks that are absolute musts for getting it right. Here are the key ingredients:- The right potatoes: This is the biggest challenge here in the U.S. In Germany you can find potatoes that you simply cannot find here. Unlike Russet potatoes, for example, which are flaky, mealy, and generally flavorless, the kind used in potato salads in Germany are firm, deep yellow in color, buttery and flavorful. And they keep their shape well. The closest you can get to those here are Yukon Gold potatoes and those are the ones I recommend for this recipe. Also, be sure to boil the potatoes in their skins – don’t peel them first.
- Beef broth: For the best flavor there is no substitute, it must be beef broth. And it must be very strong beef broth. And it must be hot when you pour it over the potatoes so they soak it up. Make sure you let the potatoes sit for at least a full hour after you pour the broth over. If you’re vegetarian or vegan you can substitute vegetable broth.
- German mustard: I know the recipe doesn’t call for much, but it must be German mustard (mild) if you want it to taste the way it’s supposed to. The kind I use in most of my German recipes is the Alstertor Düsseldorf Style Mustard .
- Vinegar: No apple cider or balsamic vinegar. It needs to be the strong white vinegar. A vinegar very commonly used in Germany for this salad and salad dressings is called Essig Essenz (can also be found in some Asian grocery stores – Koreans like to use it for kimchi). It’s super concentrated vinegar and you only need a very little of it. If you have access to this vinegar, you would add just a teaspoon or two in addition to the white vinegar, and reduce the amount of white vinegar accordingly. Of course you’ll always want to do a “taste test” before pouring the final mixture over the potato salad.
- Onions: You want them crunchy but not overly so, and you want them saturated with flavor. So add them to the beef broth/vinegar mixture when you heat it up.
- Oil: Lots of it. In olden days homemade beef broth would be used which contained plenty of fat. Nowadays we mostly use store-bought broth in cans or beef bouillon cubes/granules which are all void of fat. So adding oil is absolutely essential to achieving the right texture. As my German mom says, Schwäbischer Kartoffelsalat needs to be “schmalzig”. Use a neutral-tasting oil. Germans typically use either rape seed oil (Rapsöl) or sunflower oil.
