Food and nutrition expert Sara Haas has shared a simple technique for making creamy soup without using any cream, relying instead on a tin of white beans. Speaking to The Spruce Eats, she explained that her classical French culinary training taught her that texture is about technique, not dairy.
"The funny thing about creamy soups is that many of the good ones don't have much cream in them at all," she said. Often, a splash of cream is stirred in at the end purely to round out the flavours, contributing very little to the overall texture.
The bean purée method
Haas prefers using blended beans as a thickener. "It's simple," she told The Spruce Eats. Ladle some hot broth into a blender alongside drained, rinsed cannellini or other white beans, blitz until completely smooth, then pour the purée back into the simmering pot and allow everything to combine.
She describes the result as one that "looks creamy" and "tastes creamy," yet no cream, flour, or cornstarch has been added whatsoever. Butter beans work just as well as cream, with fewer calories.
Nutritional benefits over cream
Substituting heavy cream for blended white beans renders soup luxuriously smooth while considerably boosting its nutritional value. Unlike cream, which contributes little beyond saturated fat and calories, a full tin of puréed beans provides roughly 350 kcal, yet delivers a substantial boost of dietary fibre (up to 20 grams) and plant-based protein (15-20 grams), alongside essential micronutrients such as iron and folate.
For a comparable number of calories (approximately 350 kcal), heavy cream offers almost none of these nutritional benefits, being composed predominantly of saturated fat. Cream should only be used to finish a soup, as depending on it for bulk can dilute the flavour of your stock and, according to culinary experts, it is prone to splitting or curdling when reheated.
Other thickening alternatives
When blended until completely smooth with hot liquid, beans produce a glossy consistency that replicates dairy without the heaviness, allowing vegetables, herbs, and quality stock to take centre stage. Haas also advocates for vegetable purées as discreet thickening agents. Cauliflower — steamed or roasted — is a particularly strong option because, as she notes, it has a "neutral flavour like beans," meaning it fades into the background while still adding body.
Stir a cup of blitzed cauliflower into a pan of mushroom, broccoli, or parsnip soup, and you'll notice an immediate silkiness, with your aromatics and stock doing the talking. Built-in thickening is another worthy alternative to cream. "Another idea is to puree part of your soup and add it back to the pot," said Sara, a technique that works particularly well with starchy vegetables such as potatoes and winter squash. Spoon out a serving of your simmered soup — perhaps sweet potato bisque or roasted butternut — blend it until silky-smooth, then pour it back into the pan.
