Kale Minestrone with Pistou

This vibrant kale minestrone with pistou is a sophisticated take on the classic Italian vegetable soup. It is a hearty, nourishing dish that celebrates the deep, earthy flavours of Tuscan kale and creamy cannellini beans. The base is built with a traditional sofritto of carrots, celery and leeks, simmered slowly with a Parmesan rind to create a rich, savoury broth. For the best results, use high-quality tinned tomatoes and fresh herbs to provide a robust foundation for the seasonal vegetables.

Perfect as a healthy midweek meal or a comforting weekend lunch, this vegetarian soup is topped with a bright, zesty pistou. This French-style condiment, made with fresh basil, lemon zest and olive oil, cuts through the richness of the stew to add a hit of modern freshness. Serve with a thick slice of crusty sourdough bread for a satisfying, wholesome dinner that the whole family will enjoy.

Tie oregano, rosemary, and bay leaves together with kitchen twine.

Heat oil in a large heavy pot over medium. Add pancetta, if using, and cook, stirring often, until browned around the edges, about 5 minutes. Add onion, leek, carrots, celery, garlic, and red pepper flakes; season with salt. Cook, stirring often, until onion is translucent and carrots are tender, 10–12 minutes. Add tomato paste and cook, stirring to coat, until slightly darkened, about 3 minutes.

Add tomatoes, crushing with your hands as you go, then herb bundle, Parmesan rind, if using, and 1450ml water or reserved bean cooking liquid, or a combination. Season with salt and pepper and bring to a boil. Add potatoes, reduce heat, and simmer until potatoes are tender and flavours have melded, 20–25 minutes. Add kale and beans; cook until kale is tender, about 5 minutes. Discard Parmesan rind and herb bundle.

Do ahead: Soup can be made 2 days ahead (or 2 months if frozen). Let cool; transfer to airtight containers and chill.

Pulse garlic and basil in a food processor until finely chopped. Transfer to a small bowl and stir in oil, Parmesan, and lemon zest; season with salt. Serve soup topped with pistou.
