Tips
To make this dish ahead of time, don’t top the gratin with the breadcrumbs. Cover and refrigerate the gratin and breadcrumb mixture separately for up to 2 days. To prepare the gratin, sprinkle it with the breadcrumb mixture and bake, uncovered, at 400° for 45 minutes or until it’s heated through, squash is tender and top is golden brown.
Try replacing Gruyère cheese with different cheeses such as smoked Gouda, Monterey Jack and/or smoked Cheddar.
