Onigiri

If you’re looking for a way to turn dinner into a hands-on, curiosity-filled experience, onigiri is the perfect place to start.

These simple Japanese rice balls are soft, salty, and incredibly satisfying, but more than that, they’re an invitation. An invitation to explore a new food culture, to try something different, and to let your kids play with their food in the best possible way.

Onigiri have been part of Japanese food culture for centuries. Often tucked into lunchboxes, enjoyed on the go, or made fresh at home, they’re a staple built on simplicity and care. Traditionally, they’re shaped by hand and sometimes filled with ingredients like salted salmon, pickled plum, or tuna.

And the best part? They’re wonderfully simple and nearly impossible to mess up, making them the perfect starting point for families who want to explore how people around the world eat, one small (and delicious) step at a time.

How to make onigiri at home

Here is a brief overview of how to make this recipe. For the full set of written directions, please scroll down to the recipe card below.

Step One: Make the rice

Start by placing the rice in a bowl and covering it with water. Let it soak for 20 minutes (this helps the rice cook evenly and gives it the right texture). Drain the soaking water and rinse the rice until the water runs mostly clear.

Add the rice and 2 cups of water to your Instant Pot. Cook on high pressure for 2 minutes, then allow a natural release. Once the rice is done, carefully remove the lid and let it cool slightly until it’s safe to handle.

Step Two: Shape and Assemble

Fill a small bowl with water (this will be your best friend while shaping the rice).

Wet your hands, then scoop about ½ cup of rice. Gently press and shape it into a triangle (or any shape your family likes). If you’re using an onigiri mold, wet it first and follow the package directions.

Sprinkle a little sea salt on both sides of the rice ball, if using. Wrap a strip of nori around the rice ball, on the side, underneath, or across the top, so it’s easy to hold and adds extra flavor.

Repeat with the remaining rice, keeping your hands wet as you go to prevent sticking.

Tips for making Japanese rice balls

• Do not substitute long grain rice in this recipe. You must use sushi rice.
• Keep your hands wet at all times to prevent sticking
• Use a rubber spatula or silicone spoon to handle the hot rice
• Don’t over-pack the rice, gentle pressure works best
• If using a mold, wet it before each use

Make it a family food adventure

This is where onigiri really shines, not just as a recipe, but as an experience.

Instead of shaping all the rice balls yourself, set up a simple “onigiri station” and invite your kids to be part of the process. Give everyone a small portion of rice, a bowl of water for their hands, and let them create their own.

How kids can help

• Shape the rice into triangles, circles, or fun designs
• Sprinkle on salt or wrap the nori strips
• Choose and add their own fillings
• Help scoop and portion the rice (with a spoon or scoop)

It might get a little messy and that’s part of the fun.

As your family gets more comfortable, you can turn this into a mini taste adventure by offering a few filling options and letting everyone build their own combinations.

Fun filling ideas to try

• Tuna salad
• Cooked salmon
• Teriyaki chicken
• Avocado slices
• Pickled vegetables

To add a filling, place about ¼ cup of rice in your hands or mold, add a small spoonful of filling in the center, then top with another ¼ cup of rice and gently press to seal.

You can keep it simple with familiar flavors, or try something new together and talk about how these kinds of fillings are used in Japanese cooking.

Either way, you’re doing more than making dinner, you’re helping your kids explore the world through food, one rice ball at a time.
