Squash + Wild Rice Gratin

There are only 91 days of fall, but this bake channels the season 365. Tender, perfectly sweet delicata squash (how festive), nutty wild rice, and earthy French lentils are the hearty base of this operation. Red cabbage, Brussels sprouts, and celery root keep the message on-brand but the umami-rich, gravy-like parsnip sauce steals the show and coats this medley of ingredients.
