Ingredient Breakdown
What You’ll Need to Make Onigiri
To whip up these delightful rice balls, gather the following ingredients. Onigiri is pretty versatile, so feel free to mix and match!
Short-Grain Rice (preferably sushi rice):
- 4 cups, this is the star of the show. The stickiness is what helps shape the onigiri.
- Tip: If you can’t find sushi rice, any short-grain rice will work, but you might need to adjust your water-to-rice ratio!
Water:
- 4 ½ cups for cooking the rice. The right ratio helps achieve that perfect sticky texture.
Salt:
- 1 teaspoon for seasoning the rice. A couple of pinches goes a long way in bringing out the flavors.
Rice Vinegar:
- 2 tablespoons, this adds a lovely zesty flavor to the rice.
Fillings (choose any combination):
- Pickled Plum (Umeboshi): A classic option that’s both tart and savory.
- Tuna Salad: Mix canned tuna with mayo and a dash of soy sauce, kid-approved!
- Grilled Chicken: Shredded and seasoned, it makes for a hearty filling.
- Avocado and Cream Cheese: For a fresh twist! This mix is, hands down, my go-to for non-traditional onigiri.
- Seaweed Sheets: Nori strips for wrapping or adding flavor.
Optional Toppings:
- Sesame Seeds or Furikake: Sprinkle some over the finished rice balls to give them that extra pop of flavor!
When it comes to onigiri, the best part is the versatility. You can even use whatever you have on hand, so if you have leftover veggies or meats, toss them in!
Let’s Get Cooking!
Step-by-Step Instructions
Prepare the Rice (10 minutes)
- Rinse the 4 cups of sushi rice thoroughly under cold water until the water runs clear, this removes excess starch. You want that rice to be beautifully fluffy, not gummy.
- Drain it well and let it sit for about 30 minutes it’s like giving your rice a mini spa day!
Cook the Rice (20 minutes)
- In a large pot, combine the rinsed rice and 4 ½ cups of water. Bring it to a boil over medium-high heat.
- Once it’s boiling, reduce the heat to low, cover the pot, and let it simmer for 15-20 minutes. You’ll know it’s done when you see little holes form in the rice and it smells heavenly!
Season the Rice (5 minutes)
- Once the rice is cooked, remove it from heat and let it sit covered for another 10 minutes. This lets it finish steaming.
- In a small bowl, mix the 1 teaspoon of salt with 2 tablespoons of rice vinegar.
- After the rice has cooled slightly, fluff it with a fork and gently mix in the vinegar mixture. You want to coat the rice evenly, giving it that mild, zesty flavor that enhances the onigiri!
Shape the Onigiri (10 minutes)
- Wet your hands with water and sprinkle a touch of salt on your palms, this keeps the rice from sticking and adds a nice flavor.
- Take about ½ cup of rice and mold it into a triangular shape in your hands, or a round ball if you prefer.
- If you’re adding a filling, create a small indentation in the center and fill it with your choice of goodness, then seal it back up.
Wrap It Up! (Optional, 5 minutes)
- If you like, wrap a strip of nori around the onigiri. This not only adds flavor but makes for easier handling too!

And voilà! You’ve got your beautiful onigiri ready to serve!
