Arrabiata in Italian simply means “angry” and references the excessive spicy notes this sauce traditionally has. Do not feel the need to go beyond what you like. If you like it milder, halve the amount or even omit the red pepper flakes from the sauce. While marinara sauce is also a classic tomato-based pasta sauce, I always see arrabiata as marinara’s angry (spicy) cousin. This is such a tasty sauce on its own but can be served with chicken or eggplant Parmesan on the side for an Italian American feast. One note: while not traditional, if your sauce is too spicy for your taste, a splash of cream can really help mellow it out.
