Hungarian Mushroom Soup Recipe for UK Home Cooking

Hungarian mushroom soup is a paprika-seasoned soup of mushrooms, onion, stock and dill, finished with sour cream for a creamy, gently tangy bowl. This version uses ingredients readily found in UK supermarkets and gives you a rich, comforting soup without needing a long simmer; Hungarian households and recipes have their own variations.

Ingredients

2 tablespoons unsalted butter (28 g)
1 tablespoon olive or neutral oil (15 ml)
1 medium yellow onion, finely chopped (about 1 cup or 150 g)
7 cups sliced chestnut or button mushrooms (about 500 g)
1½ tablespoons sweet Hungarian paprika (about 10 g)
2 tablespoons plain flour (16 g)
4 cups vegetable or chicken stock (950 ml)
1 bay leaf
¾ teaspoon fine salt (about 4 g), plus more to taste
¼ teaspoon freshly ground black pepper (about 0.5 g)
½ cup whole milk (120 ml)
½ cup full-fat sour cream (120 g), at room temperature
2 tablespoons chopped fresh dill (about 6 g)
1 tablespoon lemon juice (15 ml)

Instructions

Prepare the ingredients, about 15 minutes. Finely chop the onion and slice the mushrooms to a similar thickness so they cook evenly. Measure out the paprika and flour before you start; paprika can scorch quickly, so having them ready makes the next step easier. Let the sour cream come towards room temperature while you cook, which helps it blend smoothly into the soup.
Soften the onion, 5 minutes. Set a large, heavy-based saucepan over medium heat and add the butter and oil. Once the butter has melted, stir in the onion. Cook for about 5 minutes, stirring occasionally, until softened and translucent but not browned. If the onion begins to catch, lower the heat rather than adding extra butter.
Cook the mushrooms, 10 minutes. Add the sliced mushrooms, salt and black pepper. Stir to coat them in the buttery onion, then cook for about 10 minutes. They will release moisture, shrink and become tender. Stir every couple of minutes, and wait until most of the liquid in the pan has evaporated; this concentrates their flavour and prevents the soup from tasting watery.
Add paprika and flour, 1 minute. Turn the heat to low and sprinkle in the paprika and flour. Stir continuously for 1 minute, coating the mushrooms and onion evenly. Keep the mixture moving and do not let the paprika darken or burn, as scorched paprika can taste bitter. The flour will make a light paste around the vegetables and thicken the stock later.
Simmer the soup, 15 minutes. Pour in the stock gradually, stirring as you go to loosen any flour from the base of the pan. Add the bay leaf, bring the soup to a gentle simmer, then reduce the heat so it bubbles softly rather than boiling hard. Simmer uncovered for 15 minutes, stirring once or twice. Remove the bay leaf when the mushrooms are tender and the broth has thickened slightly.
Stir in the milk and sour cream, 3 minutes. In a small bowl, whisk the milk into the sour cream a spoonful at a time until smooth. Stir a ladleful of hot soup into this mixture, then slowly pour it back into the saucepan while stirring. Keep the soup over low heat for about 3 minutes, until hot and cohesive. Do not let it boil after adding the sour cream, because high heat can make it split or turn grainy.
Finish and taste, 1 minute. Stir in the chopped dill and lemon juice. Taste the soup and adjust the salt, pepper or lemon as needed. Serve hot. If it seems thicker than you like, stir in a splash of stock or milk; if it seems thin, give it a minute more over low heat before serving.

Tips

Choose paprika with care. Sweet Hungarian paprika gives the soup its characteristic mellow, warm flavour. It is stocked by many UK supermarkets, but if you cannot find it, use good-quality sweet paprika. The soup will still work, though it may taste less distinctly Hungarian. Avoid using hot paprika as the full replacement; add a small pinch of chilli only if you specifically want heat.
Brown the mushrooms by giving them room. A wide saucepan helps moisture evaporate. If your pan is small and the mushrooms are crowded, cook them in two batches so they soften and concentrate rather than steam. Chestnut mushrooms have a deeper flavour, while white button mushrooms make a milder soup; either is suitable.
Keep the dairy smooth. Full-fat sour cream is less prone to splitting than a low-fat version. Bring it towards room temperature, whisk in milk, and temper it with hot soup before adding it to the pan. Once it is in, keep the heat gentle and avoid a rolling boil.
Adjust thickness at the end. Mushroom moisture and stock brands vary, so the finished soup can be a little thicker or thinner from one batch to another. Add stock or milk a tablespoon at a time to loosen it. If you want it thicker, let it simmer briefly before adding the sour cream rather than boiling the finished soup.

Serving Suggestions

Serve the soup in warm bowls with an extra spoonful of sour cream, a little chopped dill and a light dusting of paprika. Crusty bread, rye bread or a warm bread roll is useful for soaking up the creamy broth. For a more substantial meal, pair it with a simple green salad dressed with vinegar or lemon; the fresh acidity balances the richness of the soup.

If serving it as a first course, use smaller portions and keep the garnish restrained so the paprika and mushrooms remain the main flavours. As a main meal, offer bread and perhaps a plate of sliced cucumber or radishes alongside. The soup is best served promptly after finishing, while the dill is fresh and the sour cream is still silky.

Variations

Make it vegetarian: Choose vegetable stock and check that it is suitable for your preferences. The rest of the ingredients are vegetarian-friendly. For a more savoury, earthy note, replace up to 150 g of the chestnut mushrooms with rehydrated dried porcini. Soak the porcini according to the packet instructions, chop them, and strain the soaking liquid carefully through a fine sieve or coffee filter before adding some of it in place of an equal amount of stock. Dried porcini are not essential, but they add a more concentrated mushroom flavour.

Use fresh mushrooms in a mix: A combination of chestnut, button and a few oyster mushrooms gives varied texture. Keep the total at about 500 g so the stock-to-mushroom balance stays close to the original. For a more traditional-style tang, some cooks use cultured sour cream; ordinary full-fat sour cream is a practical UK option. Crème fraîche can be substituted in the same quantity, but it is richer and less tangy, so add the lemon gradually and taste.

Make it gluten-free: Replace the plain flour with 1 tablespoon (8 g) cornflour mixed with 2 tablespoons (30 ml) cold water. Do not add it with the paprika. Simmer the soup as directed, stir in the cornflour mixture near the end, and simmer gently for 1–2 minutes until thickened before adding the dairy. Check that your stock is labelled gluten-free. The texture may be slightly glossier and less softly flour-thickened.

Add a little heat: Stir in a small pinch of hot paprika alongside the sweet paprika, or offer chilli flakes at the table. Keep sweet paprika as the main seasoning so the soup retains its rounded flavour. A large quantity of hot paprika can overwhelm the mushrooms and make the dairy finish taste less balanced.

Storage and Reheating

Cool leftovers promptly and refrigerate them within 2 hours of cooking in a covered, shallow container. Keep the soup refrigerated for 3–4 days. Because sour cream is already stirred in, the texture may be less smooth after chilling, but gentle reheating usually brings it back together. Do not leave the pot at room temperature for an extended period while it cools.

Reheat only the portion you plan to eat in a saucepan over low to medium-low heat, stirring regularly and avoiding a hard boil. Add a splash of milk or stock if it has thickened in the fridge. Reheated leftovers should reach 165°F (74°C); check the centre with a food thermometer. You can also reheat an individual serving in the microwave, stopping to stir at intervals so it heats evenly, and checking that it reaches the same temperature.

For longer storage, freeze the soup in portions for up to 2 months for best quality. Dairy-based soups can separate slightly after thawing, so defrost overnight in the refrigerator and reheat gently while whisking. If you know you will freeze some, an option is to freeze the soup before adding the sour cream and milk, then thaw, reheat and add the dairy fresh. Do not can this soup at home.

Frequently Asked Questions

Can I make Hungarian mushroom soup without sour cream?
Yes. Crème fraîche is the closest easy swap and gives a richer, somewhat less tangy result. Plain full-fat yoghurt can work, but it is more likely to split, so bring it towards room temperature, temper it with hot soup and stir it in off the heat. You can also leave out the sour cream and serve the soup as a brothier, dairy-free version, though it will no longer have the classic creamy finish.

Can I use dried dill instead of fresh?
Yes. Use about 2 teaspoons (2 g) dried dill in place of 2 tablespoons fresh. Dried herbs are more concentrated and have a different aroma, so stir them in during the last few minutes of simmering rather than relying on them as a fresh garnish. If you have fresh parsley, a small amount can add colour at serving, but it will not taste exactly like dill.

Why did my soup turn grainy or split?
The dairy was probably heated too quickly or brought to a boil. Sour cream is easier to incorporate when it is not fridge-cold, whisked with milk, and tempered with a ladleful of hot soup before it goes into the pan. Keep the soup at a gentle heat afterwards. If it has only just begun to separate, take it off the heat and whisk gently; it may improve, although it might not become perfectly smooth again.

Can I make it ahead?
Yes. Make the soup through the stock simmer, cool it safely and refrigerate it, then reheat gently and add the tempered milk and sour cream shortly before serving. You can also make the complete recipe a day ahead, but the dairy may need a careful whisk while reheating. Keep the soup refrigerated and use it within 3–4 days.

What mushrooms work best in the UK?
Chestnut mushrooms are a dependable choice because they have a fuller flavour than standard white button mushrooms and are widely available. Button mushrooms are a good, mild alternative, and a mix can add variety. Use fresh, firm mushrooms and slice them evenly. Avoid washing them under a running tap for a long time; brush off dirt or wipe them with a damp cloth so they do not carry unnecessary water into the pan.
