Cheesy Cauliflower & Cannelini Bean Gratin

Cheesy Cauliflower & Cannellini Bean Gratin layers tender cauliflower florets and white beans in a garlic-butter sauce, then bakes them under a crisp, cheesy breadcrumb topping until golden. Prep requires just 15 minutes of chopping and assembly, with a 30-minute bake time. This dish delivers protein and fiber from the beans alongside the natural sweetness of roasted cauliflower. Serve hot as a hearty side or a vegetarian main for a satisfying, fuss-free meal.
