Cucumber-Dill Soup with Spring onions

This chilled cucumber and dill soup is a vibrant, refreshing choice for a light vegetarian lunch or an elegant starter on a warm day. By blending fresh cucumbers with tangy buttermilk and Greek-style yogurt, the recipe creates a beautifully silky base that carries the punchy flavours of citrus and garlic. The addition of aromatic dill provides a classic herbal lift that complements the cool, crisp temperament of the vegetables.

Ideal for hosting, this easy homemade soup can be prepared well in advance to allow the flavours to develop in the fridge. It is a naturally healthy, low-calorie option that feels indulgent thanks to its creamy texture. Serve it in chilled bowls with a final twist of white pepper and a crusty loaf of sourdough for a satisfying, seasonal meal.
