Slow Cooker Roasted Gourd and Sweet Potato Soup

This autumn-inspired soup is made by simmering roasted gourds and sweet potatoes in a slow cooker, resulting in a thick, velvety texture. Flavored with cinnamon and apple cider, it develops deep, layered notes as the ingredients break down and blend together over hours of gentle cooking. The final dish is warm, inviting, and has a smooth, hearty appearance.

Notes

Add a small squeeze of lemon juice or apple cider vinegar before serving to brighten the flavors.
