Comforting and hearty, this soup embodies the rich taste of squash in a perfect autumnal dish. Vegetables like celery, carrots, and onions add depth, maple syrup-glazed apples bring sweetness, and ginger finishes it all off. A perfect balance of flavor, this seasonal creation is great as a meal or appetizer. Plus, since it's all made in the slow cooker, it barely requires any work!
