Ingredients
- 1 1/2 lb cremini or white mushrooms, sliced
- 1 large yellow onion, diced
- 3 tbsp unsalted butter
- 2 tbsp sweet Hungarian paprika
- 1 tbsp all-purpose flour
- 4 cups vegetable or chicken broth
- 2 tbsp soy sauce
- 1 cup sour cream, at room temperature
- 1/2 cup milk or half-and-half
- 1 tsp fresh lemon juice
- 2 tbsp chopped fresh dill, plus more for serving
- 1 tsp kosher salt, plus more to taste
- 1/2 tsp black pepper
Instructions
- Sauté the mushrooms. Melt the butter in a large pot or Dutch oven over medium-high heat. Add the mushrooms and onion; cook 7–8 minutes, stirring occasionally, until the mushrooms release their liquid and turn golden.
- Bloom the paprika. Reduce heat to medium. Stir in the paprika and flour and cook 1 minute, stirring constantly — blooming the paprika in fat unlocks its deep, sweet flavor. Do not let it scorch.
- Build the broth. Pour in the broth and soy sauce, scraping up any browned bits. Simmer 10 minutes until slightly thickened and the flavors meld.
- Temper the sour cream. In a bowl, whisk the room-temperature sour cream with the milk. Ladle in 1 cup of hot soup, whisking constantly, then stir the mixture back into the pot. This keeps the sour cream silky instead of curdled.
- Finish bright. Stir in the lemon juice, dill, salt, and pepper. Taste and adjust — the soup should be earthy, paprika-rich, and just tangy.
- Serve. Ladle into warm bowls, swirl with extra sour cream, and shower with more dill. Crusty bread for dunking is essential.
💡 Soup smarts
Sweet Hungarian paprika is worth seeking out — it is fruitier and deeper than generic paprika and makes the whole soup. Room-temperature sour cream plus tempering is the anti-curdle insurance; never boil the soup after the dairy goes in. A mix of mushroom varieties (cremini plus shiitake or oyster) adds wonderful depth. Leftovers keep 4 days refrigerated and reheat gently over low heat.
Common questions
Can I make this vegan?
Yes — use olive oil or vegan butter, vegetable broth, and swap the sour cream for a cashew cream or plain unsweetened vegan yogurt stirred in off the heat.
Why did my soup curdle?
The sour cream was likely too cold or the soup was boiling when it went in. Temper it with hot broth first and keep the soup at a gentle simmer after adding dairy.
Can I freeze Hungarian mushroom soup?
It freezes okay for up to 2 months, but dairy soups can separate. For best results, freeze before adding the sour cream, then stir it in fresh when reheating.
What do I serve with it?
Crusty sourdough or rye bread for dunking, and a simple green salad. It is rich enough to be a full meatless dinner on its own.
