This variation on the Italian classic cooks up into a thick, delicious soup that's perfect for a cold winter night. The secret to making great minestrone is to sauté the vegetables over medium heat, adding each one in turn. Starting with the onion builds a robust, flavorful base that provides a solid backbone for the soup. Take your time to ensure that the vegetables are cooked and you'll reduce your overall cooking time. Prep: 30 min Cook: 3 hours Total: 3 hours 30 min Serves 10 to 12
