Everyday Polish mushroom soup features popular white button mushrooms cooked along with potatoes and vegetables for a satisfying dish. Easy to make, delicious and ready in under 40 minutes!
Prepare mushrooms: Finely chop ⅓ of the mushrooms and cut the remaining mushrooms into thin slices. Set aside.
Cook vegetables: Heat half the oil and butter in a pot, add the bay leaf, allspice berries and onion and cook gently for about 3 minutes stirring often. Add the celeriac, carrot and finely chopped mushrooms. Cook over a medium heat for about 8 minutes or until the moisture has been absorbed, stirring frequently. Stir in the flour until no longer visible.
Cook soup: Add the potatoes, stock, pepper to taste, cover and bring to the boil then lower the heat and simmer for about 15 minutes.
Brown mushrooms: In the meantime, prepare the rest of the mushrooms. In a large pan melt the remaining butter with oil, add the sliced mushrooms and season with salt and pepper. Cook over a moderately high heat for 8-10 minutes until the moisture has been absorbed and the mushrooms are lightly browned, stirring occasionally.
Add mushrooms: Stir the mushrooms into the soup and continue cooking for 3-4 more minutes. Remove from the heat.
Add cream: In a bowl combine the cream and sour cream, stir in 2-3 tablespoons of the hot soup then pour the entire mixture into the soup stirring with a whisk until fully incorporated. Add the parsley, adjust the seasoning as needed and serve.
Notes
Use ordinary white button or closed cup mushrooms.
*Wipe the mushrooms clean with kitchen paper (do not rinse).
