A rich and creamy twist on classic mac and cheese, this dish swaps pasta for tender cauliflower florets coated in a velvety cheddar sauce. The golden breadcrumb topping adds a satisfying crunch, making it a comforting low-carb side or main.
Storage: Keep leftovers in an airtight container in the fridge for up to 3 days. To reheat, place individual portions in a microwave-safe dish and heat in 30-second bursts until hot, or reheat in a 350°F (177°C) oven for 10-15 minutes. Freezing: Assemble the casserole but do not bake, wrap tightly, and freeze for up to 2 months. Thaw overnight in the refrigerator, then bake as directed, adding 5-10 minutes to the baking time. The breadcrumb topping may soften after freezing; for a crunchier finish, sprinkle fresh breadcrumbs on top before reheating.
