Mushroom cream soup from champignons
Mushroom cream soup with champignons and potato is a tender, diet-friendly and remarkably fragrant first course that you can confidently make for fasting days (without cream) and for a healthy family menu. This soup is easy to digest while being surprisingly filling and wholesome thanks to the mushrooms (a source of plant protein) and celery root, which gives the dish a characteristic savory aroma and a subtle refreshing flavor. Compared to ordinary mushroom soup with chunks, the puree version turns out significantly more tender and creamy. Slice the champignons and sauté with onion in butter or oil until soft. Boil the potato and celery root in vegetable broth until completely tender. Combine everything in the pot, add cream and blend with an immersion blender to a smooth creamy consistency. Serve with croutons and herbs. Proportions for 4 servings inside.

Mushroom cream soup made from champignons is a beautifully light first course that fits perfectly into Lenten cooking, vegetarian meals, or weight-management diets. The soup contains celery root, parsnip, and parsley root along with carrots — root vegetables packed with vitamins and earthy depth. The cream texture comes entirely from blending the cooked vegetables, with no cream or animal fat needed. The result is a smooth, fragrant, almost silky soup that rivals restaurant versions while costing pennies per portion. Easy to make, quick to cook, beautiful on the plate.

- champignons – 200 g;
- celery root – 40-50 g;

Prepare all the ingredients for making the mushroom cream soup from champignons. Peel and wash the vegetables. Cut the mushrooms into slices. Having everything prepped in advance keeps the cooking flow smooth from start to finish.

Cooking
1. All the vegetables will be blended later, so precise cutting is not required. However, cut the vegetables into approximately the same size for even cooking. Cut the potatoes into cubes about 2 cm on a side.

2. Cut the root vegetables into sticks or any convenient shape. The celery, parsley, and parsnip roots are softer than potato so they cook quickly — even matchstick cuts work fine.

3. Cut the carrot in the same way into sticks. Carrot adds the warm orange hue and natural sweetness that brightens the finished soup beautifully.

4. Chop the onion randomly, but not too large. Even-sized pieces ensure the onion cooks evenly during the brief sauté before joining the soup.

5. Place the chopped potatoes in a small pot. Add one or one and a half liters of drinking water, depending on the desired thickness of the soup. Less water gives a thicker, more luxurious cream soup; more water produces a lighter version.

6. Fry the prepared root vegetables in vegetable oil until semi-cooked over medium heat. Then transfer them to the pot with the potatoes. Now the potatoes and root vegetables boil together, building the layered flavor base.

7. Separately sauté the mushrooms in vegetable oil. Cooking the champignons takes only about ten minutes — mushrooms cook quickly. Remove from heat but do not add to the vegetable broth yet.

8. Once the vegetable broth is ready, remove from the heat and blend it using an immersion blender. The blending transforms separate vegetables into the silky uniform cream that defines this style of soup.

9. Blend the vegetables until completely homogeneous. The result is a smooth cream soup. Put the pot back on the stove and add the champignons so the vegetables absorb the deep mushroom aroma. At this moment, salt the soup and adjust the taste. Add pepper or other favorite spices to preference.

10. The dietary mushroom cream soup made from champignons with potatoes is ready. The soup turns out incredibly fragrant thanks to the root vegetables and mushrooms, and the carrot gives it a light orange hue. Pour into a serving bowl, add spicy seasonings, a sprig of parsley, and serve. Such a soup is a real find when you want something light and healthy — great as a warming first course in cool weather. Add croutons if you like extra texture.

Tips and Tricks
Tip 1. Cook the mushrooms in a dry pan first to drive off moisture before adding oil. Champignons release surprising amounts of water, and starting with oil produces stewed, soggy mushrooms instead of the deep browned flavor you want. Wait for the surface to dry, then add fat. The browning that follows builds intense umami flavor that becomes the soul of the finished soup.
Tip 2. Use a homemade vegetable broth instead of plain water for a more complex flavor. Save vegetable trimmings (onion ends, carrot tops, celery leaves) in the freezer all week, then simmer 30 minutes for instant homemade broth. The depth difference is dramatic. The same technique enriches countless other recipes including mushroom soup with dried porcini.
Tip 3. Reserve a few sliced mushrooms whole rather than blending them all into the soup. The visual contrast of mushroom slices floating in the smooth cream adds restaurant elegance and provides textural interest in each spoonful. Garnish each bowl with a handful of the reserved mushrooms before serving.
Tip 4. Drizzle a thin spiral of cream, olive oil, or truffle oil on top of each bowl just before serving. The visual swirl looks professional, and the fat bloom adds richness that complements the lean broth. A scattering of fresh chopped parsley or chives finishes the presentation. Serve with crusty homemade bread on the side for a complete light meal.
FAQ
Can I use other mushrooms instead of champignons?+
Yes, and the results will be excellent. Cremini mushrooms (baby portobello) bring deeper flavor than white champignons. Wild mushrooms like porcini, chanterelles, or oyster mushrooms turn this from a humble soup into something extraordinary. Mix several varieties for the most complex flavor. If using dried mushrooms, soak first in warm water for 30 minutes and use the soaking liquid as part of the broth.
Why is my soup grainy after blending?+
Either the vegetables were not cooked through, the blender did not run long enough, or you used the wrong tool. Cook the vegetables until very soft — a fork should slide through with no resistance. Blend with an immersion blender for at least 2 full minutes, working all corners of the pot. For the silkiest texture, pass the blended soup through a fine-mesh sieve, though this is rarely necessary if the vegetables were properly cooked.
Can I make this soup creamier without adding dairy?+
Yes. Add a peeled raw potato to the cooking liquid — extra starch produces a thicker, creamier base. A handful of cashews soaked overnight in water and blended into the soup adds richness without dairy. Coconut milk works too, though it shifts the flavor toward Asian profiles. For a more luxurious texture without dairy, use less water during cooking to concentrate the natural starches.
How long does mushroom cream soup keep?+
Stored in a covered container in the refrigerator, the soup keeps for 3-4 days. The flavor actually deepens overnight as the mushroom essence permeates the vegetables fully. Reheat gently on the stove with a splash of water if the soup has thickened. Cream soups can also be frozen for up to 2 months in portion-sized containers; the texture may separate slightly upon thawing but a quick blend with the immersion stick restores smoothness.
