Mentai tamagoyaki is a traditional dish consisting of a light and fluffy omelet with Alaskan pollock roe called mentaiko. In order to prepare it, the eggs are usually mixed with mayonnaise and mirin, and when the eggs starts to firm, it's rolled up, then cut into small sushi-like rolls.

Mentaiko roe can be incorporated into the omelet before it's cut or it can be placed on top of the rolls before serving. The dish is typically prepared in a tamagoyaki pan.
