Short answer

Blend a starchy ingredient into it — potato, white beans, bread, cashews, or some of the soup's own vegetables. All of them thicken and enrich without dulling the flavour the way cream does.

Cream makes soup richer but it also flattens it, muting the very flavours you spent time building. Every method here adds body from something that already tastes of something.

Step by step

Blend part of the soup itself.Take out a ladleful or two, blend it smooth and stir it back. It thickens with no new ingredient and no dilution of flavour. The simplest method and often the best.
Add a potato at the start.One medium floury potato per litre, diced and cooked with everything else, then blended in. It gives a velvety texture and almost no flavour of its own.
Use white beans.A drained tin of cannellini or butter beans blended in adds body, protein and a subtle sweetness. Excellent in tomato, leek and greens soups.
Use bread.Stale bread soaked in stock and blended in is the traditional Mediterranean thickener. It gives a soft, rich texture and it is how gazpacho and many bean soups are built.
Use blended nuts.Cashews soaked in hot water for twenty minutes, or ground almonds, blended into the soup. Genuinely creamy, and the standard dairy-free approach.
Roast the vegetables first.Roasting rather than boiling concentrates flavour and sugars, so the soup tastes richer at the same thickness. Especially effective with squash, carrot, cauliflower and tomato.
Finish with a fat that tastes of something.Good olive oil swirled in, a knob of butter, tahini, coconut milk, or a spoonful of yoghurt. Fat creates the impression of creaminess even in small quantities.
Reduce it rather than thickening it.Simmering uncovered concentrates everything at once. It is slower but it improves flavour as well as body, which no addition does.
Season again at the end.Thickeners dilute seasoning. Taste and add salt and acid — a squeeze of lemon lifts a thick soup out of heaviness.

Tips

Blending part of the soup back into itself is the cheapest and cleanest method.
A splash of acid at the end stops a thick soup tasting heavy.
Roasting the vegetables before making the soup does more for richness than any thickener.

Common mistakes

Adding flour or cornflour to a vegetable soup — Starch slurries give a slightly gluey, sauce-like texture and add no flavour, which is a poor trade in something whose whole point is the vegetables. Blending the vegetables themselves does the same job better.
Reaching for cream by default — Cream mutes flavour as well as adding richness, so a carefully seasoned soup often tastes duller after it goes in. If you want cream, add it at the table so people can choose.

If it doesn't work

Thin and watery

Cause: Too much stock — Fix: Blend a ladleful and stir it back, or simmer uncovered to reduce.

Thick but tastes dull

Cause: Overthickened or underseasoned — Fix: Loosen with stock, then add salt and lemon or vinegar.

Grainy after blending

Cause: Vegetables not fully cooked, or fibrous ones used — Fix: Cook until completely soft, and pass fibrous soups such as celeriac or asparagus through a sieve.

Split after adding yoghurt

Cause: Too hot — Fix: Take the pan off the heat and stir yoghurt in at the end, or stabilise it by stirring a spoonful of the hot soup into the yoghurt first.

Questions people ask

What is the best dairy-free way to make soup creamy?

Blended soaked cashews or a tin of white beans. Both give genuine body rather than just fat, and neither dominates the flavour. Coconut milk works but brings a strong taste of its own.

Does adding potato make soup taste of potato?

Barely, if you use one floury potato per litre. It disappears into the texture. Use more than that and it starts to dominate and can turn gluey when blended.
