Slow Cooker Minestrone Soup Recipe

This slow cooker minestrone soup delivers a hearty medley of vegetables, beans, herbs, and pasta, simmered to a tender and comforting finish. The recipe uses a base of sautéed aromatics combined with pureed white beans and a mix of fresh and dried herbs, enriched by Parmesan rind for depth. It's slowly cooked in broth to develop layered flavors and finished with fresh greens and al dente pasta for texture and substance.
