10 best winter squash casserole recipes

1. Merritt's Butternut Squash Gratin

"Slightly sweet golden squash is topped with a savory herbed cheese-breadcrumb topping," says Merrittorious. "It's been my signature dish every Thanksgiving for the last 12 years. It takes a bit of work, but it is so, so worth it. Your guests will ask you for the recipe, so be prepared."
