How to Make Onigiri Step-by-step

Now that you know what ingredients to mix in. Let’s move on to creating your own Onigiri! I will show you the ingredients and step-by-step instructions in the following section!

📋 Ingredients

Here are the ingredients for Onigiri (amounts are in the recipe card below).

• Cooked Japanese rice (Japanese short-grain rice): See below
• Fillings of your choice: See below
• Salt

Japanese Short-grain Rice

The best rice for Onigiri is Japanese short-grain rice (or Japonica rice), which is more starchy than long-grain type and is easy to stick together and keep shape when making Onigiri. Long-grain rice like Jasmine rice and basmati rice will fall apart as they are not sticky enough.

Koshihikari rice is the most famous and popular brand of Japanese rice. Or you can use the one labeled “sushi rice” on the packaging.

While standard Onigiri is typically made with white plain rice, you can also opt for brown rice if you prefer a more nutritious option.

How to Cook Rice

A rice cooker is easy and convenient to cook rice; however, I like the traditional method – using just a pot! You can find helpful tips, equipment to use, and step-by-step instructions in this Japanese rice recipe.

Fillings

🔪Instructions

Let me walk you through how to make it step by step. These steps are the same for any ingredient. Click here to watch the How to Make Onigiri recipe video.

1. Mix rice and ingredients: Put cooked rice in a large bowl, add the ingredients of your choice, and mix.
2. Wet hands: Set aside a small bowl of water and a small plate of salt, and wet both hands with water.
3. Add some salt: Put salt on your finger (I usually dip two fingers), place it on the palm of your hand, and rub it between your hands.
4. Spread the salt: You can see the salt spread on the entire palm.
5. Rice on your palm: Put 1/3 (small size) or 1/2 (regular size) of rice on your hand.
6. Form: Hold the rice with both hands to make it stick together. Then, form a triangle shape (or round shape) by pressing gently with your palms and fingers while rolling it several times.

Serve

There you go! Here are five onigiri variations for you! Which one is appealing to you?

With these colorful rice balls, it would be fun to have an onigiri party (our kids love it).

🔪Instructions: Using Plastic Wrap

Using plastic wrap is a super easy and quick way to shape Onigiri. Also, it’s safer, as holding rice with wet hands will increase germs over time.

1. Place the cooked rice onto a plastic wrap. Lightly sprinkle a pinch of salt evenly over the rice.
2. Wrap the rice.
3. Using both your palms and fingers, gently apply pressure to shape the rice into a triangular form.

If you are in one of the situations below, shaping rice with plastic wrap is a good idea.

• You want to take Onigiri as a bento (lunch box).
• You want to store Onigiri in the freezer to eat later.
• You are in a furry.
• The rice is too hot to hold.

Onigiri Molds

If you find it difficult to form Onigiri by hand, don’t worry! You can use a tool like Onigiri molds or Onigiri press to make the process easier and more consistent.

Storage

If you don’t eat the Onigiri immediately, wrap each with plastic and store them in an airtight container.

• Room temperature: You can store the wrapped Onigiri at room temperature for half a day if it’s not a hot summer day.

• Refrigerate: You can store the wrapped Onigiri in the refrigerator for a couple of days. But if you keep it in the fridge, the rice will be dried out and get hard. So I recommend heating it in a microwave oven to have a more fluffy texture before you eat it.

• Freeze: You can store the wrapped Onigiri in the freezer for up to one month. When you’re ready to enjoy your frozen Onigiri, heat them in a microwave oven just before consuming them. Avoid thawing them at room temperature as it may cause them to become dry.

What to Serve With

Onigiri pairs well with almost anything, such as grilled fish, tamagoyaki (Japanese rolled omelet), stir-fried vegetables, and simmered dishes.

This one example is perfect if you like to have a light meal.

• Corn Onigiri
• Stir-fried Tofu and Broccoli
• Pickled Cucumbers
• Daikon Salad with Sesame Dressing
• Kabocha miso soup would be an excellent addition to this.

Let’s Grab an Onigiri and Go for a Walk!
