Creamy Tomato Soup

This is a creamy tomato soup, hearty with root vegetables and a bright tomato base. Onions, celery, carrots, and potatoes are gently softened before simmering with chopped tomatoes, passata, and stock. Once blended until smooth, a splash of milk adds richness and a velvety texture. It's a great make-ahead option, chilling well for a few days or freezing for longer.
