Hungarian Cream of Mushroom Soup, Rich and Paprika-Scented

Hungarian cream of mushroom soup is a savory, gently tangy soup built around mushrooms, sweet paprika, broth, milk, sour cream, and fresh dill. This Hungarian-style version keeps the mushrooms in slices and finishes the soup with dairy for a creamy, comforting bowl; proportions and seasonings vary among cooks, so the paprika and dill can be adjusted to taste.

Ingredients

3 tablespoons unsalted butter (42 g)
1 tablespoon olive oil (15 ml)
1 medium yellow onion, finely chopped (about 150 g)
1 pound cremini or white button mushrooms, cleaned and sliced (454 g)
2 teaspoons sweet Hungarian paprika (about 5 g); use hot paprika for a spicier soup, or a mixture of sweet and hot
1/4 cup all-purpose flour (30 g)
3 cups low-sodium chicken or vegetable broth (720 ml)
1 cup whole milk (240 ml)
1/2 cup full-fat sour cream (120 g)
1 tablespoon fresh lemon juice (15 ml)
2 tablespoons chopped fresh dill (about 6 g), plus extra for serving if desired
1 teaspoon kosher salt (about 5 g), or to taste
1/2 teaspoon freshly ground black pepper (about 1 g)

Instructions

Prepare the ingredients. Chop the onion, slice the mushrooms, and measure the remaining ingredients before you start cooking. Wipe mushrooms with a damp towel or brush off any visible dirt; avoid soaking them, since water clinging to the surface can slow browning. Keep the sour cream chilled until it is time to temper it.
Soften the onion. Set a heavy soup pot or Dutch oven over medium heat. Add the butter and olive oil. When the butter has melted, add the onion and cook for 5 minutes, stirring now and then, until it is soft and translucent but not browned. If it begins to take on color quickly, lower the heat.
Cook the mushrooms. Add the sliced mushrooms, salt, and black pepper. Cook for 9 minutes, stirring every couple of minutes. They will release moisture, shrink, and then begin to look glossy and tender. Let most of the liquid evaporate before moving on; the mushrooms do not need to be deeply browned, but a little color adds savory flavor.
Add the paprika and flour. Take the pot off the heat briefly and stir in the paprika so it coats the mushrooms without scorching. Sprinkle in the flour and stir until no dry patches remain, then return the pot to medium heat and cook for 1 minute. This brief cooking helps remove the raw-flour taste. Paprika can turn bitter if it sits against a very hot pot, so keep stirring and do not let it darken.
Make the broth base. Pour in the broth a little at a time, stirring well after each addition to loosen the flour mixture and prevent lumps. Once the broth is incorporated, bring it just to a gentle simmer. Reduce the heat to medium-low and simmer uncovered for 12 minutes, stirring occasionally and scraping the bottom of the pot. The soup should thicken lightly while the mushrooms remain tender.
Add the milk. Stir in the milk and heat the soup gently for 3 minutes, until steaming. Do not let it boil vigorously. Taste a spoonful and check the texture: it should be creamy and spoonable, not as thick as a sauce. If you prefer a looser soup, stir in a splash of broth or milk.
Temper and stir in the sour cream. In a small bowl, whisk the sour cream with a ladleful of hot soup until smooth. Stir that mixture back into the pot over low heat. Add the lemon juice and dill, then warm gently for about 2 minutes, stirring, without bringing the soup to a boil. Taste and adjust the salt, pepper, lemon, or dill. Serve hot.

Tips

Choose the right paprika. Sweet Hungarian paprika gives the soup its characteristic warm, rounded flavor without making it hot. Paprika can lose its aroma as it ages, so use a fresh, fragrant tin if available. If you only have ordinary sweet paprika, it will work; the finished soup may taste a little less vivid. For gentle heat, replace up to half with hot paprika rather than adding a large amount all at once.
Give the mushrooms room. Use a broad pot and stir in batches if your pot is small. Crowded mushrooms release moisture and steam instead of cooking down, so allow that liquid to evaporate before adding the flour. Cremini mushrooms have a deeper, earthier flavor, while white button mushrooms make a milder soup.
Keep the dairy smooth. Take time to whisk hot soup into the sour cream before returning it to the pot, and keep the finished soup below a boil. A hard boil after adding sour cream can make the dairy look grainy or separated. Full-fat sour cream is more forgiving; reduced-fat versions can be thinner and more prone to splitting.
Adjust thickness carefully. The flour thickens the broth, and the soup will thicken further as it stands. If it is too thick, loosen it with broth or milk a few tablespoons at a time. If it seems thin, simmer the broth base for another few minutes before adding the milk and sour cream rather than boiling the finished soup.

Serving Suggestions

Serve the soup in warm bowls with a little extra chopped dill and a small spoonful of sour cream on top. Crusty bread, rye bread, or buttered toast is useful for dipping and makes the meal more filling. For a simple lunch, pair a bowl with a green salad dressed with a sharp vinaigrette; its freshness balances the creamy soup. At dinner, serve smaller portions before roasted vegetables, a baked potato, or a plate of dumplings.

The soup is satisfying but not meant to be a thick purée: the sliced mushrooms give each spoonful texture, while the broth stays creamy enough to sip. If you want a more substantial bowl, add cooked egg noodles or boiled potatoes just before serving, rather than simmering them in the soup for a long time. They can absorb broth as they sit, so keep extra broth nearby for loosening leftovers or individual portions.

Variations

Make it vegetarian: Use vegetable broth. A flavorful, not overly salty stock helps the mushrooms and paprika remain prominent. The chicken-broth version is a common option, but the soup does not depend on meat for its main flavor.

Use dried mushrooms: Replace up to 2 ounces (55 g) of the fresh mushrooms with dried porcini or another dried mushroom. Rehydrate them in hot water according to the package directions, chop them, and strain the soaking liquid through a fine sieve or a coffee filter to catch grit. Use some of that liquid in place of an equal amount of broth. Dried mushrooms make the soup more intensely earthy, so start with a modest quantity.

Make it gluten-free: Replace the all-purpose flour with 2 tablespoons (about 16 g) cornstarch mixed with 2 tablespoons (30 ml) cold water. Omit the flour step, add the broth and simmer the mushrooms, then stir in the slurry and simmer until lightly thickened before adding milk and sour cream. Check that the broth and paprika are labeled gluten-free if that matters for your cooking needs.

Change the herbs or richness: Fresh parsley can replace the dill for a milder, less distinctive finish, though dill is a familiar partner for creamy mushroom soup. For a richer bowl, replace half the milk with light cream. For a lighter texture, use whole milk as written and do not reduce the sour cream too far, since it contributes both body and tang.

Storage and Reheating

Let the soup stop steaming heavily, then transfer it to a shallow, covered container and refrigerate it within 2 hours of cooking. It keeps for 3 to 4 days in the refrigerator. The sour cream may look slightly less smooth after chilling; stir the soup gently as it warms. Avoid leaving the pot at room temperature for an extended period.

Reheat only the portion you plan to serve in a saucepan over low to medium-low heat, stirring frequently. Heat leftovers to 165°F (74°C), checking with a food thermometer, and avoid a rolling boil because the dairy may separate. If the soup has thickened in the refrigerator, stir in a little broth or milk while reheating. You can also microwave a serving in a covered, microwave-safe bowl, stirring at intervals and checking that it reaches 165°F (74°C) throughout.

Freezing is possible, but soups containing sour cream and milk can separate or become grainy after thawing. For the best texture, freeze the mushroom-and-broth base before adding the milk, sour cream, lemon, and dill. Cool it promptly, freeze in a sealed freezer-safe container, and use within about 2 to 3 months for best quality. Thaw in the refrigerator, reheat the base, then add the dairy and finish as directed. If freezing the fully finished soup, expect some texture change and whisk gently as it warms.

Frequently Asked Questions

Can I make Hungarian cream of mushroom soup ahead?

Yes. For the smoothest texture, prepare the mushroom and broth base a day ahead, refrigerate it promptly, and add the milk, tempered sour cream, lemon, and dill while reheating. You can also make the complete soup ahead; warm it slowly and stir often, adding a splash of broth if it has thickened.

Why did my sour cream curdle?

Sour cream is more likely to separate if it is added cold to very hot soup or if the soup boils afterward. Whisking a ladleful of hot soup into the sour cream first gradually warms it, and adding it over low heat helps keep the mixture smooth. If the soup has already separated, gentle stirring may improve its appearance, but avoid blending it aggressively while hot.

Can I use canned cream of mushroom soup instead of fresh mushrooms?

Not as a direct replacement in this recipe. Canned condensed soup already contains thickeners and seasonings, so using it in place of the fresh mushrooms would change the flavor and texture substantially. If fresh mushrooms are unavailable, frozen sliced mushrooms can work; thaw and drain them, then cook off excess liquid before adding the flour.

Is this soup spicy?

With sweet paprika, it is savory and aromatic rather than hot. Paprika varieties differ, so check the label: sweet paprika adds warmth without much heat, while hot paprika brings a clear kick. Use a blend if you want a little spice, and taste before adding more because the soup’s flavor develops as it simmers.

Can I make the soup without sour cream?

Yes. Use an equal amount of crème fraîche for a similarly tangy, rich finish, or stir in plain yogurt off the heat for a lighter but more tart result. Yogurt is more likely to split, so temper it carefully and do not boil the soup. If you omit the sour cream altogether, the soup will be less tangy and less creamy; a small extra splash of milk will not fully replace its richness.
