Ingredients
- Cooked Japanese Short-Grain Rice: 3 cups (cooked according to package instructions) – Use freshly cooked rice for the best results. Sushi rice is ideal, but regular short-grain rice works well too.
- Nori Seaweed Sheets: 4-6 sheets, cut into strips – Use roasted nori for the best flavor and texture.
- Water: For wetting your hands – This prevents the rice from sticking to your hands.
- Salt: A pinch, for seasoning the rice – Enhances the flavor of the rice.
- Optional Fillings (choose one or more):
- Canned Tuna Salad: 1/2 cup, drained well – Mix tuna with mayonnaise, chopped celery, and a pinch of pepper.
- Flaked Salmon: 1/2 cup, cooked and flaked – Season with a little soy sauce or furikake.
- Umeboshi (Pickled Plum): 2-3 plums, pitted and chopped – Adds a salty and sour flavor.
- Kombu Tsukudani (Simmered Kelp): 1/4 cup, chopped – A savory and slightly sweet filling.
- Bonito Flakes (Katsuobushi): 1/4 cup – Adds a smoky and umami flavor.
- Spicy Cod Roe (Mentaiko): 1/4 cup – Adds a spicy and savory kick.
- Optional: Sesame seeds, for sprinkling – Adds a nutty flavor and visual appeal.

Instructions
- Prepare the Rice: Cook the Japanese short-grain rice according to the package instructions. Once cooked, fluff the rice gently with a rice paddle or fork. Lightly sprinkle with a pinch of salt and mix well. Allow the rice to cool slightly until it’s warm but not too hot to handle.
- Prepare Your Workspace: Have a bowl of water readily available to wet your hands. Cut the nori seaweed sheets into strips, approximately 1-2 inches wide and 4-6 inches long. Prepare your chosen fillings.
- Wet Your Hands: Wet your hands thoroughly with water. This is crucial to prevent the rice from sticking to your hands. Shake off any excess water.
- Shape the Onigiri: Grab about 1/2 cup of the warm rice. Gently form a loose ball in the palm of your hand.
- Add the Filling (Optional): If using a filling, make a small indentation in the center of the rice ball. Place a small amount (about 1-2 teaspoons) of your chosen filling into the indentation.
- Seal the Filling: Gently close the rice around the filling, ensuring it’s completely enclosed.
- Form the Shape: Gently shape the rice ball into a triangular or round shape. To create a triangle, gently press the rice ball between your palms, forming a pointed shape. To create a round shape, simply keep the rice ball rounded. Avoid squeezing the rice too tightly, as this will make it dense and less appealing.
- Wrap with Nori: Take a strip of nori and wrap it around the base of the onigiri, covering the bottom third or half of the rice ball. Press the nori gently to adhere to the rice. You can also use small pieces of nori to decorate the onigiri.
- Repeat: Repeat steps 3-8 with the remaining rice and fillings.
- Serve and Enjoy: Serve the onigiri immediately or pack them for lunch or a snack. They are delicious served at room temperature.
Tips for Success
- Use Freshly Cooked Rice: Freshly cooked rice is stickier and easier to shape than day-old rice.
- Don’t Overcook the Rice: Overcooked rice will be mushy and difficult to work with.
- Wet Your Hands Regularly: Keep your hands wet throughout the shaping process to prevent the rice from sticking.
- Don’t Squeeze Too Tightly: Gently shape the rice without squeezing it too hard, as this will make the onigiri dense.
- Experiment with Fillings: Get creative and try different fillings to find your favorite combinations. Consider adding pickled vegetables, grilled meats, or even vegetarian options like avocado or tofu.
- Use a Rice Cooker: A rice cooker will ensure perfectly cooked rice every time.
- Season the Rice: A pinch of salt is essential for enhancing the flavor of the rice. You can also add other seasonings like furikake or sesame oil.
Storage Instructions
Onigiri are best enjoyed fresh, but they can be stored for later. To store onigiri:
- Room Temperature: Onigiri can be stored at room temperature for up to 2 hours, especially if it’s a hot day.
- Refrigerator: Wrap each onigiri individually in plastic wrap and store them in the refrigerator for up to 24 hours. The rice may become slightly firm in the refrigerator, but it will still be edible.
- Freezer: For longer storage, wrap each onigiri individually in plastic wrap and then place them in a freezer-safe bag or container. Freeze for up to 1 month. To thaw, transfer the onigiri to the refrigerator overnight or microwave for a short period of time until warmed through.

FAQ
- Can I use brown rice? While traditional onigiri are made with white short-grain rice, you can use brown rice if you prefer. Keep in mind that brown rice is less sticky than white rice, so it may be more difficult to shape.
- Can I use a mold to shape the onigiri? Yes, you can use onigiri molds to create perfectly shaped rice balls. These molds are available at most Asian grocery stores or online retailers.
- What if I don’t have nori seaweed? While nori is a classic component of onigiri, you can omit it if you don’t have any. You can also try using other types of seaweed or even lettuce leaves to wrap the rice balls.
- Can I make onigiri ahead of time? Yes, you can make onigiri ahead of time and store them in the refrigerator or freezer. Just be sure to wrap them tightly to prevent them from drying out.
- What are some other filling ideas? The possibilities are endless! Some other popular filling ideas include teriyaki chicken, shrimp tempura, kimchi, and edamame.
