Oud en Nieuw is the Dutch name for the New Year's Eve and New Year's Day celebration associated with eating oliebollen.
The phrase literally means “old and new,” referring to the transition from the old year to the new one. Dutch families commonly celebrate with gatherings, fireworks, and festive foods. Oliebollen are deep-fried balls of dough, often containing raisins or currants and served with powdered sugar.
The food's name means “oil balls,” a direct reference to the frying method. Oliebollen are sold by temporary seasonal stalls and bakeries during the winter holiday period, and they are especially associated with the turn of the year.
Oud en Nieuw is not the name of a single parade or television program. It describes the holiday period itself. Another Dutch New Year's food, appelbeignets, consists of battered apple rings, but those are distinct from oliebollen.
