Flavours of the World: How to make Japanese onigiri

Onigiri is delicious and easy to make!

One of the wonderful things about homeschooling is that being in the kitchen can definitely be part of the curriculum! We’re studying Japan at the moment and one of the suggestions in our Kiwico Atlas Discover Japan box was to try our hand at onigiri.

At it’s simplest, onigiri is a fun gluten free snack that uses a sticky rice to create a treasure box sandwich around a delicious filling of your choice. They are wonderfully easy to make and can be as creative (or quick) as you like.

The key ingredient that you will need is Japanese Short Grain Rice. This is sometimes marketed as ‘sushi rice’ in Western supermarkets although this is actually a misnomer, the same rice can be used to make sushi but while sushi uses vinegar, salt, and sugar to provide seasoning, onigiri uses plain steamed rice and relies on the nori (dried seaweed) and filling for flavour.


Your choice of fillings; for instance:

  • Smoked salmon and cream cheese
  • Tinned tuna chunks + mayonnaise + cooked corn
  • Bonito flakes and soy sauce
  • Cooked chicken and avocado
All kinds of onigiri designs are possible

Think about what design you would like to use for your onigiri. If you want to keep it simple, use scissors to cut the nori sheets into smaller and shorter strips that you wrap around the base of the onigiri as a handhold. You can also get creative and decorate them into whatever you can imagine! There are fascinating videos on YouTube with plenty of ideas – be aware that fancier designs may utilize special tools to cut the seaweed and moulds to press the rice into. These can often be picked up cheaply online or from stores specializing in Japanese homewares.


  1. Cook your rice fresh and allow to cool slightly (it should be warm while making the onigiri). I like to use a rice cooker and make just enough rice for the meal.
  2. Prepare your filling while the rice is cooking.
  3. Have a bowl of water available to wet and wash your hands (the rice is sticky!).
  4. Traditionally, salt is rubbed onto both hands and helps to flavour the rice while you shape it. You then scoop some warm rice onto one hand, make it into a flattish nest shape, place 1-2 tsp of filling in the middle, then gently squeeze into a ball or triangular shape. Tip: If this feels a bit tricky, try lining a small bowl with gladwrap and laying the rice on top. Apply filling to centre, pop a little more rice on top, and then pull the gladwrap up at the corners (into a raindrop shape) and mould the rice (keeping the filling in the centre).
  5. You can then decorate the onigiri as you like.

Tip: You don’t need to use any nori but it does provide a pleasant umami flavour. You may prefer to simply dip your onigiri in soy sauce or coconut amino acids (an allergy friendly substitute). You may also like to sprinkle a furikake seasoning onto your onigiri; there are a range of flavours.
