To prepare this delicious rotini pasta casserole, begin by preheating your oven and greasing a baking dish. Cook the rotini pasta according to the package instructions, then drain and set aside.

In a small bowl, mix some melted butter with breadcrumbs and sprinkle this mixture over the casserole for a nice crunchy topping.
Finally, bake the dish in the preheated oven for approximately 30 minutes, or until the sauce bubbles and the breadcrumbs turn golden brown.
