German Soup Names: Classic Dishes and Potato Soup

Kartoffelsuppe, or German potato soup, is a hearty soup made with potatoes, vegetables, broth, and herbs; it is served throughout Germany in regional and family versions. German soup names such as Erbsensuppe (pea soup) and Linsensuppe (lentil soup) often describe a main ingredient, while names such as Hochzeitssuppe point to a traditional occasion. This creamy, gently seasoned Kartoffelsuppe is a useful starting point for exploring those dishes, and it can be made on a weeknight with ordinary ingredients.

Ingredients

2 tablespoons (28 g) unsalted butter or 2 tablespoons (30 ml) neutral oil
1 medium yellow onion, about 1 cup chopped (150 g)
1 medium leek, white and light-green parts only, about 1 cup sliced (130 g), rinsed well
2 medium carrots, about 1 cup diced (130 g)
2 celery ribs, about ¾ cup diced (90 g)
2 pounds (900 g) starchy potatoes, such as russets, peeled and cut into ¾-inch (2 cm) cubes
6 cups (1.4 L) low-sodium vegetable broth
1 dried bay leaf
1 teaspoon (1 g) dried marjoram
¾ teaspoon (4 g) fine salt, plus more to taste
¼ teaspoon (0.5 g) freshly ground black pepper, plus more to taste
⅛ teaspoon (0.3 g) ground nutmeg
½ cup (120 ml) heavy cream
2 tablespoons (8 g) chopped fresh flat-leaf parsley
1 teaspoon (5 ml) apple cider vinegar, optional, for finishing

Instructions

Prepare the vegetables. Chop the onion, leek, carrots, and celery into small, roughly even pieces so they soften at a similar pace. Rinse the sliced leek in a bowl of cold water, separating the layers to remove trapped grit, then lift it out and drain. Peel the potatoes and cut them into cubes about ¾ inch (2 cm) across. Keep the potato pieces reasonably uniform; very large chunks take longer to cook, while tiny ones can dissolve before the vegetables are tender.
Soften the aromatics. Set a large heavy pot or Dutch oven over medium heat and add the butter or oil. When the butter has melted, stir in the onion, leek, carrot, and celery. Cook for 7 to 8 minutes, stirring occasionally, until the onion looks translucent and the vegetables begin to soften. If the leek or onion starts to brown, lower the heat. The aim is a gentle, sweet vegetable base, not deeply caramelized vegetables.
Add the potatoes and broth. Stir in the potato cubes, broth, bay leaf, marjoram, salt, and pepper. Raise the heat until the liquid reaches a gentle boil, then turn it down so the soup simmers steadily rather than bubbling hard. Cover the pot partly, leaving a small gap for steam to escape. This keeps the soup from boiling over and helps the potatoes cook evenly.
Simmer until tender. Cook for 20 to 22 minutes, stirring once or twice and scraping the bottom of the pot. The potatoes are ready when a knife or fork slips into a cube easily. If they are still firm in the center, simmer for a few more minutes and check again. Remove and discard the bay leaf before blending; its flavor has steeped into the broth, but the leaf itself should not be eaten.
Make the texture creamy. Take the pot off the heat. Use an immersion blender to blend about half the soup, moving the blender carefully through the pot, then stir well. This leaves some vegetable and potato pieces intact while thickening the broth. For a smoother soup, blend more; for a chunky, rustic bowl, mash a portion of the potatoes with a potato masher instead. Avoid running a countertop blender full of hot soup, since steam can force the lid off; if using one, work in small batches and follow the blender maker’s instructions.
Finish and season. Stir in the cream and nutmeg, then return the pot to low heat for about 3 minutes, stirring until the soup is hot. Do not let it boil vigorously after adding the cream. Taste and adjust the salt and pepper. Add the optional cider vinegar a little at a time if the soup tastes too rich; it should brighten the flavor without making the broth noticeably sour. Stir in the parsley just before serving.
Serve hot. Ladle the soup into warm bowls, making sure each serving has a mixture of creamy broth and tender vegetable pieces. Offer extra parsley and black pepper at the table. The recipe makes six moderate portions as a main course with bread, or six to eight smaller first-course portions.

Tips

Choose the potato for the texture you want. Russets break down readily and help thicken the soup. Yukon Gold potatoes hold their shape a little better and have a naturally buttery texture, so use them if you want more distinct pieces. You can also use half of each type. Avoid waxy salad potatoes if you want the partly blended broth to become thick and cohesive.
Clean leeks thoroughly. Dirt often collects between a leek’s layers. Slicing it first and rinsing the pieces in a bowl makes it easier to loosen grit than washing only the outside of a whole leek. Lift the pieces out of the water instead of pouring the bowl through a strainer, which can send the grit back over the vegetables.
Adjust thickness after blending. Potatoes vary in starchiness, and blending time changes how thick the soup feels. If it is thicker than you like, add warm broth a splash at a time. If it seems thin, simmer it uncovered for a few minutes before adding the cream. Blend only part of the soup at first; you can always make it smoother, but it is difficult to restore larger pieces once everything has been puréed.
Use dairy thoughtfully. Heavy cream makes the finish rich, but half-and-half also works. For a dairy-free pot, use olive oil instead of butter and unsweetened oat cream or a little extra broth in place of the cream. The result will be less rich, so taste again for salt, pepper, and a small splash of vinegar at the end.

Serving Suggestions

Serve Kartoffelsuppe as a substantial lunch or an easy supper with rye bread, a crusty wheat roll, or seeded bread for dipping. A crisp green salad with a mustard vinaigrette provides a fresh contrast to the soft potatoes and creamy broth. For a more filling meal, add a plate of sliced cheese, pickles, or a simple cabbage salad alongside the soup. If serving it as a first course, pour smaller portions and follow with roasted vegetables, a savory tart, or a modest meat dish.

Some German potato soups are served with sausage, but this recipe is vegetarian as written. If you want that style, prepare cooked sausage separately according to its package directions, slice it, and add it to individual bowls. That keeps the base flexible for guests who do not eat meat and prevents the sausage from overpowering the mild marjoram and leek. A few croutons or a little extra parsley are easy toppings when you want crunch without changing the soup’s character.

Variations

German soup names are often descriptive. Erbsensuppe means pea soup, commonly made with dried split peas; Linsensuppe is lentil soup, often prepared with vegetables and sometimes sausage; and Grießklößchensuppe is broth with semolina dumplings. Flädlesuppe, especially associated with southern Germany, is clear broth served with thin strips of pancake. Hochzeitssuppe, or wedding soup, is a festive name for a clear broth with assorted additions such as dumplings, noodles, or small meatballs; recipes vary by region and household. These names offer a helpful introduction, but they do not point to one fixed recipe in every home.

To vary this Kartoffelsuppe, add ½ teaspoon (1 g) of caraway along with the marjoram for a more earthy, aromatic note. Stir in 1 cup (150 g) of frozen peas during the final 5 minutes for extra color and sweetness. For a smokier bowl, use smoked paprika sparingly—start with ¼ teaspoon (0.5 g)—rather than trying to make the entire soup taste like a smoked sausage. You can also replace up to 2 cups (480 ml) of the broth with water if your stock is strongly flavored, then correct the seasoning at the end.

For a chunky version, skip the immersion blender and mash only a few potatoes against the side of the pot. For a fully smooth soup, blend carefully in batches and return it to the pot before adding cream. If you use a countertop blender, never fill it to the top with hot liquid. A lid that allows steam to escape, small batches, and a kitchen towel held over the lid can reduce splashing, but follow the appliance instructions first.

Storage and Reheating

Refrigerate the soup within 2 hours of cooking, dividing a large pot among shallow containers so it cools more quickly. Keep it covered in the refrigerator and use it within 3 to 4 days. The potatoes may absorb broth as the soup sits, so expect it to thicken; loosen each portion with a little water or broth while reheating. If you plan to freeze some, freeze it before adding the cream for the best texture. Store it in a freezer-safe container with room for expansion and use within about 2 to 3 months for good quality.

Reheat soup gently in a saucepan over medium-low heat, stirring regularly, until the entire portion reaches 165°F (74°C). Check with a food thermometer, especially when reheating a large quantity. Avoid a hard boil, which can make a cream-based soup look grainy. Thaw frozen soup in the refrigerator overnight when possible, then heat it thoroughly and stir in cream after it is hot. Repeatedly cooling and reheating the same pot can affect both quality and safe handling, so warm only the amount you expect to serve.

Frequently Asked Questions

What does Kartoffelsuppe mean?
Kartoffelsuppe literally means “potato soup” in German: Kartoffel means potato and Suppe means soup. It is a broad dish name, not one single standardized formula. Some versions are smooth, some are chunky, and ingredients vary according to local preference and what is available.

What are some other well-known German soup names?
Useful names to recognize include Erbsensuppe (pea soup), Linsensuppe (lentil soup), Flädlesuppe (broth with pancake strips), Grießklößchensuppe (broth with semolina dumplings), and Hochzeitssuppe (a festive broth with varied additions). Gulaschsuppe, or goulash soup, is also served in Germany, though related goulash traditions extend across Central Europe. The name alone does not guarantee that every cook uses the same ingredients.

Can I make this soup without a blender?
Yes. Use a potato masher to crush some of the cooked potato against the pot, then stir until the broth thickens. You can also leave all the vegetables in pieces for a lighter, more brothy soup. A blender changes the texture, not whether the potatoes are fully cooked, so check that they are tender before choosing how much to mash.

Can I make Kartoffelsuppe ahead?
Yes. Cook the soup through the potato simmering and blending steps, cool it promptly, and refrigerate it. Reheat it to 165°F (74°C), then stir in the cream and parsley near the end. Making it ahead can deepen the blended flavors, although the potatoes may make the chilled soup thicker; add broth or water as needed while reheating.

Why did my potato soup turn gluey?
Potatoes can become gummy if they are blended for a long time, especially with a high-speed blender. For a creamy but not stretchy texture, blend only part of the soup briefly with an immersion blender, or mash a few pieces by hand. Starchy potatoes are useful for thickening, but prolonged processing breaks down their starch too thoroughly.

Is German potato soup usually vegetarian?
It can be, but there is no single rule for every regional or household recipe. Some cooks use vegetable broth and serve the soup without meat, while others add sausage or use a meat-based stock. This version uses vegetable broth and contains no meat; check broth labels if you are cooking for someone who avoids animal ingredients.
