Courgette-Basil Soup

This vibrant courgette and basil soup is a celebration of fresh, seasonal produce. By using both the delicate skins and the tender flesh of the courgettes, this recipe achieves a beautiful depth of colour and a silky texture. The addition of aromatic basil provides a fragrant, peppery finish that perfectly complements the mild sweetness of the sautéed onions and garlic. It is a wonderfully light and healthy option for a summer lunch or a delicate first course for a dinner party.

As a naturally vegan dish, this soup relies on high-quality olive oil and clever preparation techniques rather than dairy to create a rich mouthfeel. The julienned courgette garnish adds a professional touch and a pleasant bite to every spoonful. Serve this comforting homemade soup with a slice of crusty sourdough or some gluten-free crackers for a simple yet satisfying plant-based meal that the whole family will enjoy.

Cook onion and garlic in oil in a 3- to 4-quarts heavy saucepan over medium-low heat, stirring occasionally, until softened, about 5 minutes. Add chopped courgette and 1 teaspoon salt and cook, stirring occasionally, 5 minutes. Add 725ml water and simmer, partially covered, until tender, about 15 minutes. Purée soup with basil in 2 batches in a blender (use caution when blending hot liquids).

Bring remaining cup water to a boil in a small saucepan and blanch julienned courgette 1 minute. Drain in a sieve set over a bowl (use liquid to thin soup if necessary).

Season soup with salt and pepper. Serve in shallow bowls with julienned courgette mounded on top.
