Traditional southern and midwestern baked macaroni recipes default to standard elbow macaroni. Younger trades those smooth curves for corkscrew-shaped cavatappi pasta noodles, occasionally labeled as cellentani. This switch is functional rather than aesthetic.
Heavy, high-fat sauces easily slide off smooth elbow macaroni, pooling at the bottom of the casserole dish. Cavatappi offers two distinct structural advantages: external ridges running down its circumference and a hollow center coiled like a spring. The grooves catch the sauce mechanically, while the spiral hollows draw cheese into the interior through capillary action. Every single bite delivers a balanced proportion of pasta to sauce. Boiling the noodles two minutes short of al dente ensures they absorb the remaining liquid in the oven without turning to mush.
