I first made this apple butternut squash gratin for my sister’s baby shower last year and it was completely devoured. Not a crumb was left. I was a little sad because once I had had a taste of it, I was already dreaming about leftovers. I’ve been meaning to make it again every since, but it somehow slipped from my mind and then the next thing I knew, it was spring. When a good friend and his mother made the trip up to have dinner with us earlier this fall, this gratin instantly came to mind. It just seemed like the perfect dish. Warm and satisfying, while being perfectly seasonal with roasted butternut squash, sautéed apple, fresh rosemary, nutty gruyere, and a dash of cream, all topped with crunchy, garlicky breadcrumbs, this gratin is both deliciously sweet and savory. It is also guaranteed to make your house smell absolutely amazing.
The dish is substantial enough to serve as a main dish, pairing beautifully with a harvest salad of pear or apple, walnuts, and gorgonzola, but it would work equally well as a side to any fall meal. It would be an especially nice accompaniment to a Thanksgiving dinner, especially if you are looking for something that will work for both your vegetarian and meat-eating guests alike.
