A comforting and easy-to-make creamy cheesy au gratin potatoes dish with a crispy golden crust and tender, silky potatoes underneath. Perfect as a side for any occasion.
If the topping browns too quickly, tent the dish loosely with foil halfway through baking. Use gluten-free flour and breadcrumbs for a gluten-free version. For dairy-free, substitute butter with dairy-free margarine or olive oil, use coconut or almond milk, and dairy-free cheese alternatives. Let the dish rest before serving to help the sauce set and prevent sliding.
