What Exactly is German Potato Soup?
At its core, German potato soup, or Kartoffelsuppe, is a celebrated and versatile dish in German cuisine. Unlike its often thicker, cheese-laden American counterparts, traditional Kartoffelsuppe typically boasts a brothier base, achieving creaminess through the natural starch of potatoes and sometimes a touch of dairy. It’s often classified as an Eintopf, meaning a « one-pot meal, » reflecting its humble origins and ability to provide a complete, satisfying dinner. While variations exist, the signature characteristics often include a chunky texture from diced potatoes and vegetables, a savory depth from smoked meats like bacon or sausage, and an unmistakable bright tang delivered by a splash of vinegar or pickle juice. Key flavor notes often come from marjoram and parsley, making this a distinct and memorable soup.
The Regional Flavors of Kartoffelsuppe
Just like Germany itself, Kartoffelsuppe is a tapestry of regional traditions. Head north, and you might encounter a clearer, brothier version, perhaps with crispy bacon and a lighter touch. Journey south to Bavaria or Swabia, and the soup often takes on a creamier consistency, frequently incorporating local specialties like Frankfurter, Wiener, or Bockwurst sausage, or even small dumplings (Spätzle) for extra heartiness. Whether it’s a rustic Bavarian potato soup or a more refined Swabian potato soup, each region adds its unique spin, making every bowl a culinary discovery.

Ingredients You’ll Need
Creating a truly authentic and delicious German potato soup starts with understanding each ingredient’s role. Here’s a breakdown of what you’ll need to bring this traditional Kartoffelsuppe to life:
The Best Potatoes for Soup
For the perfect texture in your German comfort food, the choice of potatoes is crucial. While starchy Russets can make the soup too mushy, and overly waxy potatoes might not release enough starch for a creamy consistency, Yukon Golds are the best potatoes for soup. They strike a perfect balance: holding their shape well when cooked, yet starchy enough to create a wonderfully creamy body when lightly mashed. Red potatoes are also a good, slightly waxier alternative.
Choice of Meat: Sausage, Bacon, or Both?
The savory depth of a German potato and sausage soup is often the star. Classic choices include high-quality smoked sausages like Frankfurter, Wiener (similar to a hot dog), or Bockwurst, which add incredible flavor and texture. For an extra layer of smokiness, rendering diced bacon or pancetta at the beginning of the process provides a rich fat base for sautéing vegetables, and the crispy bacon bits make a fantastic topping. A smoked ham hock can also be simmered with the broth for an even deeper, more complex smoky flavor.
The Aromatic Foundation (Suppengrün)
Every great soup begins with a strong foundation of aromatics. In German cooking, this is often referred to as Suppengrün (soup greens). For this Kartoffelsuppe recipe, you’ll need finely diced onions, carrots, and celery. A leek is also a wonderful addition, offering a mild, sweet onion flavor. Sautéing these vegetables slowly in bacon fat or butter is key to building the first, essential layer of flavor that will permeate your entire soup.
Essential Herbs & Spices
The signature herb for German potato soup is undoubtedly marjoram, offering a delicate, earthy, slightly sweet, and peppery flavor that sets it apart. You’ll also want fresh parsley for a vibrant, fresh finish. Other traditional spices include a pinch of nutmeg to enhance the potato flavor, a bay leaf for depth during simmering, and, of course, freshly ground salt and black pepper to taste. Caraway seeds are an optional but authentic addition, especially in Bavarian versions, providing a warm, slightly pungent note.
The Broth and Finishing Touches
A good quality broth is paramount. Use either chicken or vegetable broth, ensuring it’s flavorful but not overly salty. For richness, a splash of heavy cream or milk stirred in at the end adds a luxurious mouthfeel without making it overly thick. And finally, the secret ingredient that brightens and balances all the flavors: a small amount of white wine vinegar or apple cider vinegar. This acidity cuts through the richness, elevating the entire dish, creating that distinctive tang found in the best potato soup with vinegar.
How to Make German Potato Soup: A Step-by-Step Guide
Creating this easy German potato soup is a rewarding process. Follow these steps for a perfect pot of Kartoffelsuppe every time:
Step 1: Prepare Your Ingredients (Mise en Place)
Start by washing, peeling, and dicing your potatoes into 1/2-inch to 3/4-inch cubes. Dice your onions, carrots, celery, and leeks into similar small pieces. If using bacon, cut it into small lardons. Slice your chosen sausages into rounds or half-moons. Having all your ingredients prepped and ready will make the cooking process smooth and enjoyable.
Step 2: Build the Flavor Base
In a large, heavy-bottomed pot or Dutch oven, render the diced bacon over medium heat until crispy. Remove the bacon with a slotted spoon and set aside, leaving the delicious rendered fat in the pot. If not using bacon, add a tablespoon or two of butter. Add the diced onions, carrots, celery, and leeks to the pot. Sauté gently for 8-10 minutes until the vegetables are softened and translucent, but not browned. This step is crucial for developing the foundational flavors of your soup.
Step 3: Simmer the Soup
Add the diced potatoes to the pot with the sautéed aromatics. Pour in the chicken or vegetable broth, ensuring the potatoes are just covered. Add the bay leaf and dried marjoram. Bring the soup to a boil, then reduce the heat to low, cover, and simmer for 15-20 minutes, or until the potatoes are fork-tender. Do not overcook them to the point of disintegration.
Step 4: Create the Perfect Texture
Once the potatoes are tender, it’s time to achieve your desired consistency. For a rustic, chunky soup, use a potato masher to lightly mash about one-third to half of the potatoes directly in the pot. This will release starch and create a creamy texture while leaving plenty of satisfying chunks. For a smoother, creamy potato soup with sausage, you can use an immersion blender to blend a portion of the soup, or carefully transfer about 2-3 cups to a regular blender, blend until smooth, and return it to the pot.
Step 5: The Finishing Touches
Stir the sliced cooked sausage into the soup and heat through for 5 minutes. Remove and discard the bay leaf. Now, stir in the heavy cream (if using), a crucial splash of white wine vinegar or apple cider vinegar, and the fresh parsley. Taste the soup and adjust the seasonings as needed. Add more salt, pepper, or vinegar until the flavors sing. The vinegar should be subtle, brightening the soup without making it taste sour.
Pro Tips for a Perfect Pot of Kartoffelsuppe
Even an easy German potato soup can benefit from a few expert touches. Here are some tips to ensure your Kartoffelsuppe recipe is always exceptional:
- Don’t Rush the Sauté: The initial sautéing of aromatics (onions, carrots, celery, leeks) builds the core flavor. Be patient and let them soften properly for maximum depth.
- The Magic of Vinegar: Seriously, don’t skip it! A small splash of white wine or apple cider vinegar at the very end brightens all the flavors, cutting through the richness beautifully. It’s what makes this a true German potato soup with vinegar.
- Let it Rest: Like many stews and braises, this soup tastes even better the next day. The flavors continue to meld and deepen, making it perfect for meal prep.
- Taste and Adjust: Always taste your soup before serving. Adjust salt, pepper, and especially the vinegar. A little more salt or a tiny extra splash of vinegar can transform it.
- Creamy Without Cream: For a lighter option, blend a larger portion of the cooked potatoes. Their natural starch will thicken the soup, providing creaminess without the need for dairy.
Delicious Variations and Substitutions
This German potato soup is wonderfully adaptable. Feel free to experiment and make it your own!
Vegetarian or Vegan Kartoffelsuppe
Creating a vegetarian Kartoffelsuppe is simple. Use a flavorful vegetable broth as your base. Swap out the sausage for smoked tofu (sautéed until slightly crispy), hearty sautéed mushrooms, or plant-based sausages. For a vegan version, omit the cream or use a plant-based alternative like oat milk, cashew cream, or a touch of full-fat coconut milk for richness.
Making it in a Slow Cooker or Instant Pot
For a slow cooker Kartoffelsuppe, sauté the aromatics and bacon (if using) on the stovetop first, then combine all ingredients (except cream and fresh herbs) in the slow cooker. Cook on low for 6-8 hours or high for 3-4 hours. Mash potatoes at the end and stir in finishing ingredients. For an Instant Pot German potato soup, use the sauté function for bacon and aromatics, then add potatoes, broth, and seasonings. Cook on high pressure for 8-10 minutes, followed by a natural release, then proceed with mashing and finishing steps.
Other Add-ins
Feel free to boost the nutrition and flavor with other vegetables. Parsnips or celeriac can add an earthy sweetness, while green beans or peas stirred in at the end provide freshness and color.
What to Serve with German Potato Soup
While this hearty winter soup recipe is a complete meal in itself, certain pairings elevate the experience and turn it into a truly authentic German feast.
- Crusty Bread: A must-have! A hearty rye bread (Roggenbrot), fresh German bread rolls (Brötchen), or a good quality sourdough for soaking up every last drop of the delicious broth.
- Toppings: Elevate individual bowls with crispy bacon bits (if not already in the soup), fresh chives or additional parsley, or a dollop of sour cream or crème fraîche for extra richness.
- A Simple Salad: A light, crisp green salad with a tangy vinaigrette offers a refreshing contrast to the richness of the soup, cutting through the flavors beautifully.
Storing, Freezing, and Reheating
This German Eintopf recipe is fantastic for leftovers, often tasting even better the next day!
- Refrigeration: Store leftover German potato soup in an airtight container in the refrigerator for up to 4 days.
- Freezing: If you plan to freeze the soup, it’s best to do so before adding any heavy cream or dairy. Dairy can sometimes separate or become grainy upon thawing and reheating. Freeze portions in airtight, freezer-safe containers for up to 3 months. Thaw overnight in the refrigerator before reheating.
- Reheating: Gently reheat the soup on the stovetop over medium-low heat, stirring occasionally. If the soup has thickened too much, add a splash of extra broth, water, or milk to achieve your desired consistency. If freezing without dairy, stir in the cream or milk during the reheating process.
Frequently Asked Questions (FAQ)
What is the difference between German and American potato soup?
German potato soup, or Kartoffelsuppe, is traditionally broth-based, deriving its complex flavor from smoked meats (like sausage or bacon), a specific blend of aromatics (like leeks, carrots, celery), marjoram, and a distinctive tangy finish from vinegar. It often has a rustic, chunky texture. American potato soups, conversely, are typically much thicker, creamier, and often dairy-heavy, flavored with ingredients such as cheddar cheese, crispy bacon, and sour cream, resembling a « loaded baked potato. »
How do you thicken German potato soup?
The primary thickening agent for German potato soup is the natural starch released from the potatoes themselves. This is achieved by either lightly mashing a portion of the cooked potatoes directly in the pot with a potato masher, or by blending a small amount of the soup until smooth and stirring it back in. For an even thicker consistency, a small cornstarch slurry (cornstarch mixed with cold water) can be whisked in at the end and simmered briefly.
What kind of potatoes are best for soup?
For Kartoffelsuppe, waxy or all-purpose potatoes like Yukon Gold are best. They are starchy enough to contribute to the soup’s creamy texture when partially mashed or blended, yet they hold their shape well during simmering, providing pleasant chunks in every spoonful. Red potatoes are also a good choice for similar reasons.
Why do you put vinegar in potato soup?
Adding a small amount of vinegar (typically white wine or apple cider vinegar) to German potato soup with vinegar at the end of cooking is a traditional and essential step. The acidity from the vinegar cuts through the richness of the potatoes, fat from the meat, and the cream, brightening the overall flavor profile. It provides a subtle tang that balances the savory elements without making the soup taste overtly sour, enhancing the depth and complexity of the dish.
Can I make this recipe gluten-free?
Yes, this Kartoffelsuppe recipe is naturally gluten-free. Just ensure that the broth you use is certified gluten-free (many standard broths are, but it’s always good to check the label) and that your chosen sausage does not contain any hidden gluten-containing ingredients or fillers. Most traditional German sausages are naturally gluten-free.
