This is pasta dressed with almost-Caesar salad dressing, with a fried egg on top if you like that.
Very similar to a pasta dish from prior Nigella COTM Cook, Eat, Repeat β except in this, nothing is sauteed β the raw sauce is poured over hot pasta and heated gently to take off the edge at the end.
It benefits from a bit of acid to finish, and toasted breadcrumbs for texture. A bit of heat from red chilli flakes is also nice, though not strictly necessary.
