Hungarian Mushroom Soup: What It Is and How to Make It

Hungarian mushroom soup is a stovetop soup of mushrooms, onion, paprika, and dill, usually finished with milk or sour cream for a creamy, tangy broth. It is associated with Hungarian home cooking, though family recipes vary; this version balances earthy mushrooms with sweet paprika and a gentle sour-cream finish.

Ingredients

2 tablespoons unsalted butter (28 g)
1 tablespoon neutral oil (15 ml)
1 medium yellow onion, finely chopped (about 150 g)
2 pounds mushrooms, such as cremini, white button, or a mixture, sliced (900 g)
2 teaspoons sweet Hungarian paprika (about 5 g)
3 tablespoons all-purpose flour (24 g)
6 cups low-sodium vegetable or chicken broth (1.42 L)
1 cup whole milk (240 ml)
1 teaspoon soy sauce (5 ml), optional, for a savory note
1 teaspoon fine salt (6 g), plus more to taste
1/4 teaspoon freshly ground black pepper (about 0.5 g)
2 tablespoons chopped fresh dill (about 6 g), divided
1/2 cup sour cream (120 g)
2 teaspoons lemon juice (10 ml), or to taste
1 tablespoon chopped fresh parsley (about 4 g), optional garnish

Instructions

Prepare the ingredients. Wipe the mushrooms clean with a damp towel or brush off any soil; trim the ends and slice them about 1/4 inch (6 mm) thick. Chop the onion and dill, measure the remaining ingredients, and set the sour cream out while you cook so it is not refrigerator-cold. This prep takes about 20 minutes, depending on how quickly you slice the mushrooms.
Soften the onion. Set a large heavy-bottomed pot or Dutch oven over medium heat. Add the butter and oil. When the butter has melted, add the onion and cook for about 6 minutes, stirring occasionally, until it is soft and translucent but not browned. If the pot looks dry or the onion starts to catch, lower the heat slightly.
Cook the mushrooms. Add the sliced mushrooms, salt, and black pepper. Stir to coat them in the fat, then cook for 9 minutes, stirring every minute or two. They will release liquid, shrink, and become tender. Let that liquid mostly evaporate before moving on; a little browning adds flavor, but do not let the pot scorch.
Add paprika and flour. Reduce the heat to low and sprinkle the paprika over the mushrooms, stirring for about 30 seconds so it becomes fragrant without burning. Sprinkle in the flour and stir for another 30 seconds to coat the vegetables evenly. Paprika can turn bitter if fried too long, so add the broth promptly.
Simmer the soup. Pour in the broth gradually while stirring and scraping the bottom of the pot to loosen any browned bits. Add the optional soy sauce and 1 tablespoon of the dill. Bring the soup to a gentle simmer, then cook uncovered for 10 minutes, stirring occasionally. Keep it at a steady simmer rather than a hard boil; this gives the flour time to thicken the broth without making it gluey.
Add milk and finish the base. Stir in the milk and cook at a gentle simmer for 4 minutes. Do not let the soup boil vigorously after adding dairy. Taste a spoonful and check that the mushrooms are tender and the broth is lightly thickened. If you prefer a thinner soup, add a small splash of broth; if it seems too thin, simmer gently for another minute or two.
Temper and stir in the sour cream. Put the sour cream in a small bowl and whisk in about 1/2 cup (120 ml) of hot soup, a spoonful at a time. This warms it gradually and helps prevent curdling. Take the pot off the heat, stir the tempered sour cream into the soup, then add the lemon juice and remaining dill. Taste and adjust salt, pepper, or lemon. Serve hot, garnished with parsley if desired. The cooking time is about 35 minutes in total.

Tips

Choose mushrooms with dry, firm caps and slice them evenly so they cook at the same pace. Cremini bring a deeper, earthier flavor; white button mushrooms are milder. A mix is useful when you want more complexity without relying on specialty varieties.
Use sweet Hungarian paprika if it is available: it gives the soup its recognizable warm, gently sweet pepper flavor. Regular sweet paprika is a practical substitute. Smoked paprika will make the broth taste noticeably smoky, so use only part of the amount if you want to keep the soup closer to the mild, classic style.
Keep the heat low once paprika and flour go into the pot. Burnt paprika tastes harsh, and flour can stick to a hot, dry pan. Stirring in the broth gradually is the easiest way to avoid lumps; a whisk can help if the flour does clump.
Temper the sour cream rather than adding it straight from the refrigerator to boiling soup. If the broth is already very hot, take the pot off the heat first. The soup may separate slightly if boiled after the sour cream is added, but gentle reheating usually keeps the texture smooth.

Serving Suggestions

Serve Hungarian mushroom soup in warm bowls while it is hot, with extra dill or parsley on top. A slice of crusty bread, rye bread, or a simple roll is useful for dipping and makes the soup feel like a complete meal. For a heartier table, pair it with a crisp green salad dressed with a light vinaigrette; the fresh, acidic vegetables balance the creamy broth.

The soup is filling enough to serve as a first course in a smaller portion or as a main course with bread. If offering toppings, put out a little extra sour cream, chopped dill, and black pepper so diners can adjust their bowls. Add garnishes just before serving rather than stirring them into the whole pot, especially if you expect leftovers.

Variations

For a vegetarian version, use vegetable broth; for a richer, more savory base, use chicken broth. The optional teaspoon of soy sauce adds depth but is not essential and is not a defining traditional ingredient. Leave it out if you prefer a simpler paprika-and-mushroom flavor, or use a small splash of tamari if that suits your pantry. Check broth labels if you need the finished dish to meet a particular dietary requirement.

For a lighter texture, replace the whole milk with 2% milk, knowing the soup will be less creamy. For a richer soup, use half-and-half in place of the milk, but keep the heat gentle. If sour cream is unavailable, plain full-fat yogurt can work as a topping or stirred-in finish; temper it carefully and expect a tangier result that may be more prone to curdling.

Fresh dill is a characteristic herb in many versions. If you cannot find it, use 2 teaspoons dried dill instead of the fresh amount, adding it with the broth so it has time to soften. The flavor will be less bright. You can also add a small pinch of caraway for a different aromatic note, but it will change the soup’s flavor, so start sparingly.

For a thicker, more substantial bowl, add a peeled, diced potato with the broth and simmer until tender, allowing extra time if needed. The potato starch will make the broth heavier and more filling. Another option is to blend a cup of the cooked mushrooms and broth, then return it to the pot; this thickens the soup without adding more flour or dairy.

Storage and Reheating

Refrigerate leftovers within 2 hours of cooking in a covered, shallow container. The soup keeps for 3 to 4 days in the refrigerator. It may thicken as it chills, and the dairy can look slightly separated; stir it gently as it warms. For the best texture, reheat only the portion you plan to eat rather than repeatedly warming and cooling the full pot.

Reheat on the stovetop over low to medium-low heat, stirring often, until steaming throughout. USDA FSIS guidance says leftovers should be reheated to 165°F (74°C); check the center with a food thermometer. Avoid a rolling boil, which can make the sour cream split. Add a splash of broth or milk if the soup has become too thick. You can also microwave an individual serving in a covered, microwave-safe bowl, stirring partway through and checking the temperature in more than one spot.

To freeze it, cool the soup promptly and freeze in a sealed, freezer-safe container for up to 2 months for best quality. Dairy-based soups can separate after thawing, so freeze only if a slightly less smooth texture is acceptable. Thaw overnight in the refrigerator and reheat gently, stirring well; a whisk can help bring the broth back together. Do not leave the soup at room temperature to thaw.

Frequently Asked Questions

What is Hungarian mushroom soup?
It is a savory mushroom soup associated with Hungarian cooking, typically flavored with paprika and often dill, then finished with milk, sour cream, or both. This recipe uses sliced mushrooms in a lightly thickened broth with a tangy dairy finish. There are family and regional variations, so the exact herbs and degree of creaminess differ.

Is Hungarian mushroom soup spicy?
Not usually. Sweet Hungarian paprika adds a rounded pepper flavor and color but is not hot like chili pepper. If you want a little heat, add a pinch of hot paprika or cayenne at the table so the whole pot does not become too spicy for other diners.

Can I make it without sour cream?
Yes. You can omit the sour cream and serve the soup with a squeeze of lemon, or use plain yogurt tempered with hot broth. Without sour cream, the soup will be less creamy and tangy, so taste before serving and adjust the lemon and seasoning gradually.

Why did my sour cream curdle?
Sour cream can separate when it meets very hot liquid or when the soup boils after it is added. Temper it by whisking hot broth into the sour cream a little at a time, take the pot off the heat, and stir the mixture back in. If it has separated slightly, gentle whisking may improve the appearance, though it may not become perfectly smooth.

Can I make the soup ahead?
Yes. Make it up to 3 days ahead and refrigerate it promptly. For the smoothest result, prepare the soup through the milk stage, cool and store it, then reheat gently and add the tempered sour cream, dill, and lemon just before serving. If the sour cream is already mixed in, reheat slowly and do not let the soup boil.

What mushrooms work best?
Cremini and white button mushrooms are easy to find and hold their shape in the soup. Cremini taste deeper, while white buttons are mild. You can add a modest amount of shiitake or another flavorful mushroom to a familiar base, but use varieties you know and trim any tough stems before slicing.
