A comforting baked mac and cheese casserole with a unique twist of sweetness from honey and tanginess from Dijon mustard, topped with a crispy breadcrumb crust.
Warm the milk before adding to the roux to prevent lumps and speed up thickening. Undercook pasta slightly as it will bake again. Toss breadcrumbs in melted butter before baking for a crunchy topping. Let casserole rest 5 minutes after baking to set. If topping browns too fast, cover loosely with foil halfway through baking.
