Ingredients You’ll Need

What makes the Simple Shio Onigiri so wonderful is how beautifully the few ingredients come together. Each plays a unique role in creating the perfect balance of flavor, texture, and tradition.

  • Japanese short-grain rice: The star of the show, this sticky rice is essential for shaping the onigiri and giving it that comforting chew.
  • Salt: It’s simple seasoning, but the right amount enhances the rice’s natural sweetness and preserves the onigiri’s authentic flavor.
  • Nori (seaweed sheets): Adds a delicate crunch and a subtle salty, umami-rich wrapper that keeps your hands clean and your onigiri tasty.
  • Water: For rinsing and cooking the rice, clean water ensures the grains cook evenly and achieve that ideal sticky texture.

How to Make Simple Shio Onigiri (Salted Japanese Rice Ball)

Step 1: Rinse and Cook the Rice

Begin by thoroughly rinsing the Japanese short-grain rice under cold water until the water runs clear. This step removes excess starch to prevent the rice from becoming gummy. After draining, cook the rice in a rice cooker or on the stovetop with the appropriate water ratio to achieve perfectly tender, sticky rice.

Step 2: Season the Rice with Salt

Once the rice is steamed and still hot, transfer it to a large bowl and gently fold in salt to taste. This seasoning is what transforms plain rice into the classic salted rice ball you love, so be generous but balanced to enhance, not overpower.

Step 3: Shape the Onigiri

Lightly wet your hands with water and sprinkle a pinch of salt on your palms to prevent sticking and add an extra hint of flavor. Scoop about half a cup of rice and press it firmly but gently into a triangular or round shape, making sure the rice bonds well to hold its form.

Step 4: Wrap with Nori

Cut the nori sheet into strips or rectangles large enough to wrap around the rice ball. Wrap each shaped onigiri with nori just before serving to keep the seaweed crisp, giving that perfect contrast to the tender rice.

Garnishes

While Simple Shio Onigiri shines on its own, you can elevate it with simple garnishes like a sprinkle of toasted sesame seeds, a dot of umeboshi (pickled plum), or even a tiny piece of grilled salmon tucked inside for a burst of flavor. These touches add layers of color and taste without complicating the integrity of this classic.

Side Dishes

This rice ball pairs beautifully with light sides such as miso soup, steamed vegetables, or a fresh cucumber salad. The contrasting textures and subtle flavors complement the onigiri’s simplicity and make for a balanced, nourishing meal.

Creative Ways to Present

Think beyond the traditional triangle shape and try molds to create round or oval onigiri. You can also make mini bite-sized balls for snacking or pack them in a bento box alongside colorful veggies and protein. Presenting them garnished with a sprinkle of furikake (Japanese seasoning) can make a humble dish feel extra special.

Make Ahead and Storage

Storing Leftovers

If you have leftover Simple Shio Onigiri, wrap each rice ball tightly in plastic wrap and store in the refrigerator. It’s best eaten within a day to maintain freshness and texture. Refrigerated onigiri tend to dry out, so consuming soon after preparation is key.

Freezing

You can freeze shaped onigiri by individually wrapping them in plastic and placing them in an airtight container or bag. When frozen, they remain delicious for up to a month. This is perfect if you want to prep several servings in advance for quick meals later on.

Reheating

To reheat, unwrap the onigiri and warm gently in a microwave for about 30-45 seconds until heated through. If you wrapped with nori, it’s best to remove it before microwaving and add a fresh sheet after reheating to keep the seaweed crispy.

FAQs

What type of rice is best for Simple Shio Onigiri (Salted Japanese Rice Ball)?

Japanese short-grain rice is ideal because its natural stickiness helps the rice ball hold its shape without falling apart. Long-grain rice won’t work as well due to its fluffier, less sticky texture.

Can I add fillings inside the Simple Shio Onigiri?

Absolutely! While this recipe highlights the pure salted flavor, common fillings like pickled plum (umeboshi), grilled salmon, or tuna mayonnaise can be added to the center for variety.

Is it okay to use store-bought sushi rice instead of Japanese rice?

Sushi rice can be a good substitute as it’s also short-grain, but make sure it’s not pre-seasoned. The seasoning should only come from the salt you add, to keep the onigiri simple and authentic.

How salty should the Simple Shio Onigiri taste?

It should have a gentle saltiness that enhances the natural sweetness of the rice without overwhelming the palate. Think balanced and subtle rather than heavily salty.

What’s the best way to eat Simple Shio Onigiri?

The best way is with your hands, enjoying the contrast of warm rice inside and crisp nori outside. They’re perfect for on-the-go meals, picnics, or as a quick breakfast.
