Hungarian mushroom soup is a Central European–inspired soup of mushrooms, paprika, dill, and a creamy, lightly tangy broth. This version builds flavor by browning the mushrooms before simmering them with broth and milk, then stirring in sour cream and lemon; family and regional versions vary in their herbs, richness, and use of paprika.
Ingredients
- 3 tablespoons (42 g) unsalted butter
- 1 tablespoon (15 ml) neutral cooking oil
- 1 medium yellow onion, finely chopped (about 1 cup / 150 g)
- 1½ pounds (680 g) cremini or white button mushrooms, cleaned and sliced
- 2 teaspoons (about 4 g) sweet Hungarian paprika
- 1 teaspoon (1 g) dried dill, or 1 tablespoon (3 g) chopped fresh dill
- ¼ cup (30 g) all-purpose flour
- 4 cups (950 ml) low-sodium vegetable broth
- 1 cup (240 ml) whole or 2% milk
- 1 tablespoon (15 ml) soy sauce
- ¾ teaspoon (4 g) fine salt, plus more to taste
- ¼ teaspoon (0.5 g) freshly ground black pepper
- ½ cup (120 g) sour cream, preferably full-fat
- 1 tablespoon (15 ml) fresh lemon juice
- 2 tablespoons (8 g) chopped fresh parsley, for serving (optional)
Instructions
- Prepare the vegetables. Chop the onion and slice the mushrooms into even pieces, roughly ¼ inch (6 mm) thick. If the mushrooms are gritty, wipe them with a damp paper towel or rinse them briefly and dry thoroughly; soaking them can make them harder to brown. Measure the remaining ingredients before you begin cooking.
- Soften the onion, 5 minutes. Melt the butter with the oil in a large heavy-bottomed pot or Dutch oven over medium heat. Add the onion and cook, stirring often, until soft and translucent but not browned, about 5 minutes. The oil helps the butter resist scorching while the onion softens.
- Cook the mushrooms, 10 minutes. Add the sliced mushrooms and stir to coat them in the fat. Cook for about 10 minutes, stirring occasionally. They will release liquid, shrink, and then begin to brown as that liquid evaporates. If the pot looks crowded, give the mushrooms a little more time rather than turning the heat very high; browning adds flavor, while steaming leaves the soup less savory.
- Add the seasonings and flour, 2 minutes. Reduce the heat to low. Stir in the paprika and dill for about 30 seconds, just until fragrant; paprika can taste bitter if scorched. Sprinkle the flour evenly over the mushrooms and stir for about 1 minute so it coats them and loses its raw-flour smell.
- Make the broth and simmer, 15 minutes. Pour in the vegetable broth gradually, stirring and scraping the bottom of the pot to loosen any browned bits. Stir in the milk, soy sauce, salt, and pepper. Bring the soup just to a gentle simmer, then reduce the heat so it bubbles softly. Simmer uncovered for 15 minutes, stirring from time to time, until the mushrooms are tender and the broth has thickened slightly. Avoid a hard boil, which can make milk-based soup more likely to separate.
- Finish with sour cream, 3 minutes. Put the sour cream in a small bowl and whisk in a ladleful of hot soup a little at a time. This warms it gradually and helps it blend smoothly. Turn the pot to low, stir the tempered sour cream into the soup, and add the lemon juice. Warm gently for about 3 minutes without boiling. Taste and adjust the salt, pepper, or lemon, then ladle into bowls and scatter with parsley if you like.
Tips
- Choose paprika with a fresh aroma. Sweet Hungarian paprika is the classic flavor cue, but smoked paprika is not a direct match: it gives the soup a noticeably smoky taste. If Hungarian paprika is unavailable, use fresh, mild sweet paprika; avoid hot paprika unless you specifically want heat.
- Brown in batches if needed. A crowded pan traps steam. If your pot is small, cook the mushrooms in two batches, transferring the first batch to a plate while you cook the second. Return them to the pot before adding the paprika and flour.
- Keep the dairy smooth. Lower the heat before adding sour cream, temper it with hot broth, and do not let the finished soup boil. Full-fat sour cream is less prone to splitting than low-fat versions; plain Greek yogurt can work in a pinch, but it is tangier and may separate more easily.
- Adjust thickness at the end. The soup thickens as it stands. If it becomes thicker than you like, stir in warm broth or milk a few tablespoons at a time. If it seems thin, let it simmer gently before adding sour cream rather than boiling it afterward.
Serving Suggestions
Serve the soup hot as a first course or make it a light main dish with crusty bread, rye bread, or buttered toast for dipping. A crisp green salad with a simple vinaigrette balances the creamy texture, while boiled potatoes or buttered egg noodles make the meal more filling. If serving noodles, keep them separate until plating so they do not absorb the broth during storage.
For a simple bowl, finish with a little chopped parsley and a small spoonful of sour cream. A few drops of lemon can brighten the flavor, especially if the mushrooms are particularly earthy. Offer salt and pepper at the table, but taste first: broth and soy sauce can contribute quite a bit of salt, even when the broth is labeled low-sodium.
Variations
Use a mix of mushrooms: Replace some of the cremini or button mushrooms with shiitake or oyster mushrooms. A mixed selection brings a deeper, more varied mushroom flavor, though dried mushrooms are not a one-for-one substitute by weight and should be rehydrated according to their package directions before use.
Make it vegetarian without soy sauce: The recipe is vegetarian when made with vegetable broth. If avoiding soy, use 1 tablespoon (15 ml) Worcestershire-style vegetarian seasoning or 1 teaspoon (5 ml) miso dissolved in a little warm broth. The flavor and salt level will change, so season gradually and taste before serving.
Make a richer soup: Replace up to ½ cup (120 ml) of the milk with light cream. This makes the broth richer and less bright, so keep the lemon juice and add it to taste. For a lighter texture, use 1% milk, but expect a thinner broth and take extra care not to boil it.
Add a little heat: Stir in a pinch of cayenne or use a small amount of hot paprika alongside the sweet paprika. Start with about ⅛ teaspoon (0.3 g); it is easier to add heat than to correct an overly spicy pot. Keep the dill and lemon, which help the flavors stay balanced.
Storage and Reheating
Refrigerate leftover soup within 2 hours of cooking in a covered, shallow container. It keeps for 3–4 days in the refrigerator. The broth may thicken overnight, and the mushrooms may soften further; stir in a splash of broth or milk when reheating if needed.
Reheat only the portion you plan to eat in a saucepan over medium-low heat, stirring frequently, until steaming throughout. For food safety, USDA FSIS guidance is to reheat leftovers to 165°F (74°C); check the center with a food thermometer. Keep the soup below a boil after reheating to help the sour cream stay smooth. A microwave also works: cover loosely, heat in short intervals, and stir between intervals so the soup warms evenly.
You can freeze the soup, but dairy-based soups may separate or become grainy after thawing. For the best texture, freeze the mushroom-and-broth base before adding the milk and sour cream, then thaw it overnight in the refrigerator, reheat it, and finish with the dairy and lemon. If freezing the completed soup, cool and freeze it in airtight containers, thaw in the refrigerator, and whisk gently while reheating; expect some change in texture.
Nutrition Facts

These are estimates, not laboratory measurements. The actual values vary with the type of mushrooms, milk, sour cream, broth, and soy sauce you use, as well as how generously the bowls are filled. Low-sodium broth and reduced-sodium soy sauce can lower the sodium; using cream instead of milk can increase calories and fat.
Frequently Asked Questions
What makes Hungarian mushroom soup different?
Sweet paprika and dill are defining flavors in many versions, alongside mushrooms and a creamy, often tangy broth. Recipes vary: some use more paprika, some use additional herbs or vegetables, and some are thicker or richer. This recipe uses lemon and sour cream for a gently tangy finish without claiming to represent every Hungarian or family version.
Can I use fresh dill instead of dried dill?
Yes. Use 1 tablespoon (3 g) chopped fresh dill in place of 1 teaspoon dried dill. Fresh dill tastes brighter, so stir it in near the end of cooking rather than simmering it for the full 15 minutes. You can reserve a little extra for garnish if you enjoy its flavor.
Can I make the soup ahead?
Yes. Make it through the simmering step, cool it promptly, and refrigerate it for up to 3–4 days. Reheat the base gently and stir in the tempered sour cream and lemon near the end for the smoothest texture. If the soup is already finished, it can still be reheated; use low heat and avoid boiling.
How can I make this soup gluten-free?
Use a measure-for-measure gluten-free flour blend in place of the all-purpose flour, and check that the broth and soy sauce are labeled gluten-free. Tamari is a common alternative to soy sauce, but check its label as products vary. The soup may thicken a little differently, so add broth gradually and adjust the consistency at the end.
Why did my soup turn out thin?
It may need more gentle simmering before the sour cream is added, or the flour may not have been evenly mixed into the mushrooms. Let the soup simmer uncovered for a few extra minutes, stirring often. If it is already finished, mix 1 teaspoon (3 g) cornstarch with 1 tablespoon (15 ml) cold water, stir it into the gently simmering soup, and cook briefly until thickened; do not boil hard after adding the sour cream.
Can I make it without sour cream?
Yes. Use crème fraîche for a richer, less tangy finish, or plain yogurt for a sharper flavor; stir either in off the heat or over very low heat to reduce the chance of curdling. You can also omit the sour cream and add a little extra milk, though the soup will be less creamy and less tart. Taste and adjust the lemon accordingly.
