Cauliflower Soup with Potatoes and Dill Recipe
Cauliflower soup with potatoes and dill is a well‑known Polish classic, cooked on a light vegetable or chicken stock. It has a delicate, slightly buttery flavor, noticeable pieces of cauliflower and potatoes, and plenty of fresh dill. In this version the thickness comes from the well‑cooked cauliflower core and a little cream, without a heavy flour roux.
This is one of the classic everyday soups cooked in Poland with seasonal cauliflower – it often appears in summer and early autumn as a simple, standalone lunch.
This cauliflower soup combines the taste of a homely broth with a lighter approach – the thickness comes from the cauliflower itself rather than flour. It has a clear buttery‑dill aroma while still remaining delicate and light. You also use the whole cauliflower, including the core, so there is less waste.
Why this version works
- Sautéing the leek in butter builds a deep flavor without a heavy flour roux.
- Adding the cauliflower florets only after the potatoes have partially cooked prevents them from overcooking.
- Finely diced cauliflower core naturally thickens the soup and helps avoid food waste.
- Tempering the cream with hot soup keeps it smooth and prevents curdling.
Chef's tips
If you’re using stock cubes, add less than the package suggests and season with salt only at the end – it’s easy to oversalt once the soup reduces. If it turns out too thin, ladle out some vegetables with a bit of liquid, mash them with a potato masher and return to the pot instead of reaching for flour. The cauliflower is perfect when the florets hold their shape but easily break apart under gentle pressure from a spoon.
How to serve
Serve the soup with a thick slice of wheat‑rye bread or an extra portion of boiled potatoes if you want a more filling meal. It works well as a first course before roast chicken, meatballs or a pasta bake. For a quick weekday lunch, a bowl of this soup and a simple carrot slaw are enough.
Watch out for
- Don’t cook the dill in the soup for long – add it at the very end or it will turn gray and lose its aroma.
- Avoid a vigorous boil after adding the cream, as it may curdle and make the soup grainy.
- Don’t cut the cauliflower florets too small, or they will quickly fall apart and the soup will become mushy.
Substitutions
- Replace 18% cream with 12% cream or thick evaporated milk for a lighter version.
- You can swap the butter for a tablespoon of rapeseed oil, though the flavor will be less buttery.
- Use vegetable stock instead of chicken stock if you want a fully meat‑free version.
Ingredients
- cauliflower - 1 piece
- potatoes - 4 piece
- carrot - 1 piece
- parsley root - 0.5 piece
- leek (white part) - 0.5 piece
- vegetable or chicken stock - 1.5 l
- 18% cooking cream - 100 ml
- butter - 20 g
- fresh dill - 3 tablespoon
- salt
- pepper ground black
Preparation
- Rinse the cauliflower in cold water and shake off well. Break it into bite‑sized florets. Cut off the core, peel away the tough fibers and dice it finely – it will easily break down and naturally thicken the soup.
- Peel the potatoes, carrot and parsley root. Cut the potatoes into medium cubes, and the carrot and parsley root into thin half‑moons or small cubes. Rinse the leek thoroughly between the layers and slice it thinly so it softens quickly.
- In a large pot melt the butter over medium heat. Add the leek and fry for 3–4 minutes until soft and translucent – it should be tender and fragrant but not browned, as overly browned leek can give a bitter taste.
- Pour in the stock, add the potatoes, carrot, parsley root and diced cauliflower core. Bring to a boil, then reduce the heat and cook for about 10 minutes, until the potatoes are soft at the edges but still offer slight resistance in the center when pierced with a knife.
- After 10 minutes add the cauliflower florets. Cook for another 10–12 minutes over low heat, until a fork slides into the cauliflower without force but the florets still hold their shape and don’t fall apart when stirred.
- Remove the pot from the heat. In a mug, mix the cream with 3–4 tablespoons of hot soup until smooth and uniform. Pour it in a thin stream back into the pot, stirring constantly so it doesn’t curdle.
- Return the pot to very low heat and warm for another 1–2 minutes, without letting it boil – the surface of the soup should only tremble slightly. Season with salt and freshly ground pepper until the flavor is distinct yet still delicate.
- Finally, add the finely chopped dill, stir and remove from the heat right away so it keeps its bright green color and fresh aroma. Serve hot, while the vegetables are still firm and the soup is gently steaming in the bowl.
Storage
Store the soup in the fridge for up to 3 days; the cauliflower and potatoes will get softer each day and the stock will develop a deeper flavor. Reheat over low heat without a rolling boil so the cream stays smooth and doesn’t curdle.
I most like to cook it on cooler days when I have one beautiful cauliflower and little time to stand by the stove. I often throw in leftover green beans from the fridge – the soup becomes even more vegetable‑rich.
