A warm, comforting, and quick creamy spinach gratin topped with a crispy Parmesan crust, perfect as a side or main dish.
Use freshly grated Parmesan for best crispy crust. Warm milk and cream before adding to roux to avoid lumps. Drain spinach well to prevent watery gratin. Tent with foil if crust browns too fast. Can substitute gluten-free flour and omit breadcrumbs for gluten-free version. For dairy-free, use coconut cream and plant-based butter.
