Using cottage cheese makes this dish extra creamy, and using dry pasta saves a step. The extra moisture of a young cheddar will add to the creaminess of the sauce. Cavatappi pasta is a corkscrew shape and its grooved sides hold more of the cheese mixture, but if you can’t find cavatappi, feel free to use elbow pasta. For added luxury, top with buttered breadcrumbs before the second bake.
