German Cream of Mushroom Soup with Fresh Herbs

German cream of mushroom soup, often called Champignoncremesuppe, is a smooth, savory soup made with mushrooms, broth, cream, and herbs. This home-style version browns the mushrooms for deeper flavor, then blends most of them into a velvety soup while keeping a few pieces for texture.

Ingredients

1 lb (450 g) cremini or white button mushrooms, wiped clean and sliced
4 tbsp (56 g) unsalted butter, divided
1 medium yellow onion, finely diced, about 1 cup (150 g)
2 garlic cloves, finely chopped, about 1 tsp (6 g)
3 tbsp (24 g) all-purpose flour
4 cups (950 ml) low-sodium chicken or vegetable broth
1 cup (240 ml) heavy cream
1 tsp (1 g) fresh thyme leaves, or ½ tsp (0.5 g) dried thyme
⅛ tsp (0.25 g) ground nutmeg
¾ tsp (4.5 g) fine salt, plus more to taste
¼ tsp (0.5 g) ground black pepper, plus more to taste
1 tbsp (15 ml) lemon juice
2 tbsp (8 g) chopped fresh parsley, for finishing

Instructions

Prepare the ingredients. Allow about 20 minutes to wipe the mushrooms with a damp paper towel, trim any dry stem ends, and slice them about ¼ inch (6 mm) thick. Avoid soaking mushrooms in water; they can absorb moisture and steam rather than brown. Dice the onion, chop the garlic and parsley, and measure the remaining ingredients before you start cooking.
Brown the mushrooms. Melt 2 tablespoons (28 g) of the butter in a wide, heavy pot or Dutch oven over medium-high heat. Add half the mushrooms in a single layer and cook for about 5 minutes, stirring once or twice, until they release moisture and begin to turn golden. Transfer them to a plate and repeat with the remaining mushrooms and 1 tablespoon (14 g) butter. Set aside a few browned slices to use as a garnish. Cooking in two batches gives the mushrooms room to brown; if they are crowded, they tend to soften in their own liquid.
Cook the aromatics and flour. Reduce the heat to medium and add the remaining 1 tablespoon (14 g) butter to the pot. Add the diced onion and cook for 5 minutes, stirring often, until softened but not deeply browned. Stir in the garlic and cook for 1 minute. Sprinkle in the flour and stir continuously for 1 minute, scraping the bottom of the pot so the flour coats the onion and does not scorch. The mixture will look thick and pasty; that is expected.
Simmer with broth and mushrooms. Pour in about ½ cup (120 ml) of the broth while whisking to loosen the flour mixture. Gradually whisk in the remaining broth until smooth. Return the mushrooms to the pot, then add the thyme, nutmeg, salt, and pepper. Bring the soup just to a gentle simmer, lower the heat, and cook uncovered for 15 minutes, stirring occasionally. Keep it at a quiet simmer rather than a hard boil, which can make the base reduce unevenly or catch on the bottom.
Blend and add the cream. Remove the pot from the heat and blend the soup until smooth with an immersion blender, or leave it slightly textured if you prefer. For a countertop blender, work in small batches, fill the jar no more than halfway, and vent the lid according to the manufacturer’s directions; hot liquid expands when blended. Return the soup to the pot if needed, stir in the cream, and warm over low heat for about 5 minutes. Do not let it boil once the cream is added.
Finish and serve. Stir in the lemon juice and parsley, then taste and adjust the salt and pepper. Let the soup warm for about 3 minutes, without boiling. Ladle into bowls and top with the reserved mushroom slices. The lemon should brighten the creamy flavor rather than make the soup taste distinctly sour, so add it gradually if your broth is already tangy.

Tips

Choose mushrooms with a mix of flavor and texture. Cremini mushrooms have a slightly deeper, earthier flavor than white button mushrooms, while buttons make a mild, classic soup. A mixture works well, too. Clean them with a damp cloth rather than rinsing them under running water, and slice them evenly so they cook at roughly the same rate.
Give the mushrooms space. Use a broad pot and cook in batches if needed. A crowded pan traps steam, so mushrooms soften before they brown. Browning builds the soup’s savory flavor; if liquid collects in the pot, continue cooking until most of it evaporates before moving on.
Keep the soup smooth without overheating it. Whisk the broth into the flour gradually to prevent lumps, and stir the pot while it simmers. Once cream is added, use low heat and avoid boiling. If the finished soup seems too thick, loosen it with a splash of broth; if it seems thin, simmer it gently for a few minutes before adding the cream.
Substitute thoughtfully. Vegetable broth makes the soup vegetarian, while chicken broth gives it a fuller savory note. Half-and-half can replace heavy cream for a lighter, less rich result, but it is more prone to separating if boiled. For a gluten-free version, use a measure-for-measure gluten-free flour blend and check that the broth is labeled gluten-free; the texture may be a little less silky.

Serving Suggestions

Serve this soup hot as a light first course or make it the center of a simple lunch with a substantial side. Rye bread, crusty sourdough, or warm rolls are useful for dipping and balance the soup’s creamy texture. A green salad with a sharp vinaigrette adds freshness, while a sandwich with sliced cheese or roasted vegetables makes a more filling meal.

For a German-inspired table, offer the soup before a main course of roasted vegetables, potato dishes, or a simple roast. Finish each bowl with the reserved browned mushrooms, parsley, and a few grinds of black pepper. A small spoonful of cream swirled over the top looks attractive, but it is optional; the soup is rich enough without extra garnish.

Variations

There is no single fixed version of German mushroom cream soup: home recipes vary in the mushrooms, broth, seasonings, and whether the soup is completely blended. For a more rustic bowl, blend only half the soup and leave the rest of the mushrooms whole. For a lighter mushroom-forward version, use ¾ cup (180 ml) cream and add an extra ¼ cup (60 ml) broth.

To add more woodland character, replace up to ¼ lb (115 g) of the fresh mushrooms with rehydrated dried porcini or another dried mushroom. Soak the dried mushrooms in hot water until tender, chop them, and strain the soaking liquid through a coffee filter or fine cloth before adding it in place of an equal amount of broth. Dried mushrooms bring a more concentrated, earthy flavor. Fresh chives can stand in for parsley, while a pinch of marjoram can replace some of the thyme for a different herbal note.

For a dairy-free adaptation, use olive oil or a plant-based butter alternative and an unsweetened, unflavored cooking cream made for savory dishes. Choose one that tolerates gentle heating, and expect a less buttery flavor and possibly a thinner finish. You can also omit the cream and blend in a cooked potato for body, though the result will taste less traditionally creamy; add broth a little at a time to reach the consistency you like.

Storage and Reheating

Cool leftovers promptly and refrigerate them within 2 hours in a covered container. The soup keeps for 3 to 4 days in the refrigerator. For the best texture, reheat only the portion you plan to eat. Warm it in a saucepan over medium-low heat, stirring often, until it reaches 165°F (74°C); use a food thermometer to check the temperature. Avoid a rolling boil, which can cause the cream to separate.

You can freeze the soup for up to 2 months, although cream-based soups may separate or become grainy after thawing. For a better texture, freeze the soup before adding the cream, then thaw it overnight in the refrigerator, reheat it, and stir in the cream near the end. If freezing the fully finished soup, thaw it in the refrigerator and whisk gently as it warms; blending briefly can help bring it back together. Do not leave soup at room temperature to cool for an extended period.

Frequently Asked Questions

Can I make German cream of mushroom soup without a blender?
You can serve it as a chunky soup without blending. For a partly smooth texture without a blender, finely chop the mushrooms before cooking and mash some of the softened mushrooms against the side of the pot with a spoon. The flour thickens the broth, so the soup will still have body.

What mushrooms are best for this soup?
Cremini and white button mushrooms are widely available and both work well. Cremini bring a deeper flavor, while white buttons taste milder. A small amount of shiitake or rehydrated porcini can add a more pronounced earthy note, but use them alongside the main mushrooms rather than replacing the entire amount if you want a familiar, balanced soup.

Why did my soup turn out thin or lumpy?
A thin soup may need a few more minutes of gentle simmering before the cream goes in, or it may have had too much broth added. A lumpy base usually means the broth was poured in too quickly or the flour was not stirred into the butter evenly. Whisking in the first small addition of broth until smooth, then adding the rest gradually, helps prevent lumps.

Can I prepare the soup ahead of time?
Yes. Make the soup through the simmering step, cool it promptly, and refrigerate it for up to 3 to 4 days. Reheat it to 165°F (74°C), then stir in the cream, lemon, and parsley near the end and warm gently. You can also prepare the mushrooms and diced onion a day ahead and keep them covered in the refrigerator.

Can I use milk instead of cream?
Milk can be used, but the soup will be thinner and less rich. Whole milk is the best choice if that is what you have; stir it in over low heat and do not boil the soup. For a closer cream-like texture, use half-and-half. If the soup needs more body after using milk, blend it thoroughly or simmer the broth base a little longer before adding the dairy.
