Tender cauliflower is surrounded by Gruyere cheese sauce under a crunchy coat of breadcrumbs in this make-ahead Thanksgiving side dish. Make the cauliflower and cheese sauce mixture up to two days in advance; top with breadcrumbs just before baking.
I've been making mashed cauliflower for years, but John Besh has an added step in his recipe. He puts the cooked florets in the oven for 5 minutes to dry out before mashing. I bet this could also help when making cauliflower pizza crust.
