Recipe Tips

  • Shaping onigiri can be tricky, especially if the rice sticks to your hands. To make it easier, dampen your hands with water or use plastic wrap to handle the rice without mess.
  • When shaping the rice, since eggs can be slippery and may not adhere well to the rice, using plastic wrap makes the shaping process easier and more manageable.
  • When wrapping with nori, pay attention to the texture of the sheet—one side is shiny, and the other is slightly rough. Make sure the shiny side faces outward for a more polished and appetizing look.

Storage and Reheating

Wrap each Onigiri tightly in plastic wrap to preserve their moisture and store them in the fridge for a couple of days. When ready to enjoy, microwave each Onigiri for about 20 seconds to restore its fluffy rice texture. By the way, freezing is not recommended as the process can alter the texture of the egg.

Variations

For more egg onigiri filling, I suggest trying scrambled eggs. It’s a quick and straightforward option—just mix them with rice!

  1. I like the idea that you can use an egg in the onigiri. Also I love the idea of sandwiches……
    Also if one is using ordinary rice and it’s not sticking together one could always use some melted coconut oil.

    This looks absolutely delicious. I will definitely make this soon. I gave it a 5 rating because I like eggs, I like onigiri, and I know it will be great.

    This sounds so good! I’ll be making some as soon as I get some mirin. 🙃
    I think I’ll also try my favorite marinated eggs too. (Hard boild eggs, peeled, with small holes through the whites into the yolk. Then drop the eggs into the brine from pepperoncini peppers. Let them soak at least three days in the fridge.)
