Ingredients
Method
- In a large Dutch oven or heavy-bottomed pot, melt the butter over medium heat. Add the diced onion and sauté for 3 to 4 minutes until softened and translucent. Stir in the sliced mushrooms and cook for 5 minutes, until they release their moisture and start to brown.
- Mix in the dried dill, Hungarian paprika, soy sauce, and vegetable broth. Reduce the heat to medium-low, cover the pot, and let the soup gently simmer for 15 minutes.
- In a small bowl, whisk together the cornstarch and milk until completely smooth. Pour this mixture into the soup while stirring constantly. Replace the lid and continue to simmer gently for another 10 minutes, stirring occasionally to prevent sticking.
- Remove the soup from the heat. Stir in the sour cream, fresh lemon juice, chopped parsley, salt, pepper, and a pinch of cayenne if using. Return to low heat and cook for 3 minutes more, just until warmed through. Do not let it boil, or the sour cream may curdle.
- Ladle the soup into bowls. Garnish with sautéed mushrooms, a dollop of sour cream, and extra parsley. Serve immediately with crusty bread on the side.

Notes
Do not boil the soup after adding the sour cream, as high heat can cause curdling. For the best flavor, use authentic Hungarian sweet paprika; regular paprika won't deliver the same depth. If you want a spicier soup, substitute half-sharp Hungarian paprika. This soup thickens as it cools, so you can thin it with a splash of broth when reheating. Store leftovers in the refrigerator for up to 3 days; reheat gently on the stove. For a dairy-free version, use olive oil instead of butter, and substitute canned coconut milk for the whole milk and a dairy-free sour cream.
