Skip the broccoli and let rich, creamy cheddar take center stage. Our Slow-Cooker Cheddar Soup is deeply savory, with a velvety texture that dials up the comfort. Thanks to the slow cooker, making this dish is almost effort-free—just set it, forget it, and come back to a show-stopping bowl that stands on its own. Crusty bread or fresh chives can dress it up, but honestly, this soup shines without any extras.
