This hearty, brothy soup is an ideal way to warm up during cold weather. It has butternut squash and kale as its base but features a variety of other vegetables—carrot, onion, celery—that deepen the flavor. To save time, look for already cubed, peeled squash in the produce section at the grocery store. Sage helps make this soup sing. It’s intensely aromatic and has distinct flavor. Unlike some other herbs, sage leaves are sturdy, with their own unique shape and texture—we’ve called for chopping them in this recipe. Fresh sage leaves are worth seeking out as they provide considerably more flavor.
