The Ultimate Guide to Making Delicious Vegan Onigiri: Homemade Japanese Rice Balls with Chickpea Tuna
Onigiri, also known as Japanese rice balls, are a beloved handheld snack and a staple in Japanese cuisine. Imagine perfectly seasoned sushi rice molded into a convenient shape, often a triangle or cylinder, and lovingly wrapped in a strip of savory nori (seaweed). At its heart, onigiri typically conceals a delicious filling, making each bite a delightful surprise. They are incredibly fun to make at home and even more satisfying to eat, offering a taste of authentic Japanese comfort food with every delicious morsel.
Onigiri have a rich history as traditional rice balls in Japan, serving as portable meals for travelers, samurai, and farmers for centuries. Their enduring popularity stems from their convenience, versatility, and comforting nature. If you’ve been a longtime reader of my blog, you’ll know my passion for creating delicious vegan renditions of classic Japanese dishes right in my own kitchen. From vegan Japanese milk bread to vegan katsu curry, I love bringing these flavors home. Today, we’re adding another fantastic creation to that list: a delightful vegan onigiri recipe!
The essence of making onigiri involves carefully molding sticky short-grain rice into various shapes, most commonly triangles, and securing them with a strip of crispy nori seaweed. While traditional onigiri often feature fillings like pickled ume (plum), salted salmon, or other seafood, our plant-based version takes a creative and delicious turn by incorporating a savory chickpea “tuna” filling. This not only makes the recipe accessible to those following a vegan diet but also introduces a wonderfully textured and flavorful alternative that’s sure to impress even the most discerning palates.

Essential Ingredients for Perfect Vegan Onigiri
Crafting delicious onigiri starts with selecting the right ingredients. Each component plays a crucial role in achieving the desired taste and texture. Below, we delve into the details of what you’ll need.
For precise ingredient quantities and detailed step-by-step instructions, please scroll down to the full recipe card.
- Sushi Rice (Japanese Short Grain Rice): This is the foundation of your onigiri. Japanese short grain rice is naturally sticky when cooked, which is essential for molding it into shapes that hold together without falling apart. Unlike long grain varieties, which are fluffy and separate, sushi rice develops a cohesive, slightly chewy texture perfect for compaction. Be sure to specifically look for “sushi rice” or “short grain Japanese rice” at your grocery store.
- Furikake Seasoning: This flavorful Japanese seasoning blend adds an incredible depth of umami and texture to the rice. Traditional furikake typically contains a mix of sesame seeds, dried seaweed (nori), salt, and sometimes dried fish flakes or egg. For a strictly vegan onigiri, it’s crucial to check the label carefully to ensure it does not contain any animal products. There are many fantastic vegan-friendly furikake options available that will perfectly enhance your rice.
- Vegan Chickpea Tuna: This is the star of our vegan filling! My chickpea tuna recipe is incredibly flavorful and mimics the texture of traditional tuna salad beautifully. Made primarily from mashed chickpeas and a blend of seasonings, it’s a protein-packed, wholesome, and delicious plant-based alternative. You can easily prepare this filling in advance, and any leftovers make fantastic sandwiches or wraps!
- Water: Essential for cooking your sushi rice to perfection. Using the correct ratio of water to rice, as specified by your rice cooker or stovetop method, is key to achieving the ideal sticky texture.
- Sea Salt: A pinch of sea salt on your hands when shaping the onigiri not only prevents the rice from sticking but also subtly seasons the exterior, enhancing the overall flavor profile.
- Roasted Nori (Seaweed Sheets): These thin, crispy sheets of roasted seaweed are used to wrap the onigiri, providing a convenient handle, an irresistible briny flavor, and a pleasing textural contrast. Nori can be found in most Asian grocery stores, health food stores, or easily purchased online. Look for full sheets, which you will then cut into strips.
Step-by-Step Guide: Crafting Your Own Vegan Onigiri
Making onigiri is a process that’s both rewarding and enjoyable. Follow these steps for perfectly shaped and delicious Japanese rice balls.
- Rinse the Rice Thoroughly: Place your sushi rice in a large bowl and cover it completely with cold water. Gently swish the rice around with your hand. You’ll notice the water becoming cloudy – this is excess starch. Drain the cloudy water and add fresh cold water. Repeat this rinsing process about 3-4 times until the water runs mostly clear. This step is crucial for achieving the perfect sticky-but-not-mushy texture required for onigiri.
- Cook the Rice to Perfection: For the best results and convenience, I highly recommend using a rice cooker. Follow your rice cooker’s specific instructions for cooking short-grain rice. If you don’t have a rice cooker, you can also cook the sushi rice on the stovetop. The typical ratio is 1 cup of rice to 1.25 cups of water. Bring to a boil, then reduce heat to low, cover, and simmer until all water is absorbed, about 15-20 minutes. Let it rest for 10 minutes, covered, after cooking.
- Season the Cooked Rice: Once the rice has cooked and cooled slightly (it should still be warm, not hot or cold), transfer it to a large mixing bowl. Gently fold in the furikake seasoning, distributing it evenly throughout the rice. Avoid mashing the rice; use a cutting motion with a rice paddle or spoon to incorporate the seasoning without breaking the grains. Taste and adjust the amount of furikake as desired.
- Prepare Your Chickpea Tuna Filling: If you haven’t already, now is the time to prepare your vegan chickpea tuna according to my recipe. It’s ideal if the filling is chilled before you begin shaping your onigiri, as this makes it easier to handle and helps maintain the shape of your rice balls.
- Form the Onigiri (The Art of Shaping): This is where the magic happens! Keep a small bowl of water nearby and wet your hands frequently. Sprinkle a pinch of sea salt onto your wet palms. Scoop about 1 to 2 tablespoons of the seasoned rice into one palm, gently flattening it into a small patty. Place about 1 teaspoon of the chilled chickpea tuna filling in the center of the rice. Carefully cover the filling with an additional 1 to 2 tablespoons of rice, ensuring it’s completely enclosed. Now, using both hands, gently yet firmly press and shape the rice into your desired form – a classic triangle or a round ball are common choices. The key is to apply enough pressure to compact the rice so it holds its shape, but not so much that you crush the grains.
- Wrap it with Nori: Take a full sheet of roasted nori and cut it into strips, typically about 1/3 of the width of a standard perforated nori sheet. Take one strip and carefully wrap it along the bottom or middle of your shaped onigiri, pressing it lightly to help it adhere. The nori not only adds a lovely flavor and texture but also serves as a convenient handle, keeping your fingers clean while you enjoy your snack.
- Repeat and Serve Fresh: Continue the process with the remaining rice and filling until all your onigiri are formed. You can adjust the amount of rice and filling for each to create different sizes. Onigiri are truly at their best when served immediately, while the rice is still warm and the nori is crisp. However, if you’re preparing them for later, be sure to wrap each onigiri individually in plastic wrap to maintain moisture before refrigerating.
Expert Tips for Perfect Onigiri Every Time
Achieving perfectly shaped and delicious onigiri might seem daunting at first, but with these expert tips, you’ll be a pro in no time.
- Avoid Overfilling Your Onigiri: It’s tempting to pack in as much delicious filling as possible, but moderation is key here. Too much filling can compromise the structural integrity of the rice ball, causing it to break apart when handled or eaten. Aim for about 1 teaspoon of filling per 1-2 tablespoons of rice. This ratio ensures that the filling is well-enclosed and the onigiri remains compact and sturdy.
- Keep Your Hands Consistently Wet: This is perhaps the most crucial tip for working with sticky sushi rice. Have a bowl of cold water readily available next to your workstation. Dip your hands in the water frequently, ensuring they remain damp throughout the shaping process. This thin layer of water acts as a barrier, preventing the rice from sticking to your palms and making it much easier to mold into precise shapes. Don’t forget that pinch of salt on your wet hands for extra flavor and non-stick properties!
- Master the Gentle Yet Firm Press: The art of shaping onigiri involves finding the right balance of pressure. You need to press the rice firmly enough to compact it and create a stable shape that won’t crumble, but gently enough to avoid crushing the individual rice grains. Start with light pressure and gradually increase it, feeling how the rice responds. After shaping your first one or two onigiri, you’ll quickly develop an intuitive understanding of the ideal pressure, allowing you to create beautiful, perfectly formed rice balls with ease.
Creative Vegan Filling Ideas for Your Onigiri
The versatility of onigiri allows for endless creativity, especially when it comes to plant-based fillings. Here are some more delicious vegan options to inspire your next batch:
- Savory Shiitake Mushrooms: Elevate your onigiri with the rich, umami flavor of shiitake mushrooms. Prepare these sticky sesame shiitake mushrooms, finely chop them once cooked, and tuck them into your rice balls. Their meaty texture and aromatic flavor are a fantastic addition.
- Marinated Tofu Crumbles: For a protein-packed and satisfying filling, use firm or extra-firm tofu. Press out excess water, then crumble or finely dice the marinated tofu into very small pieces. Sauté it until lightly golden and flavorful. Its neutral base readily absorbs marinades, offering a burst of savory goodness.
- Crunchy Pickled Vegetables: Add a vibrant, tangy crunch to your onigiri with a mix of pickled vegetables. You can explore traditional Japanese pickled vegetables (tsukemono) available at Asian markets, or easily whip up some homemade quick pickled radishes. The acidic brightness contrasts beautifully with the mild rice.
- Flavorful Sesame Spinach: Lightly sauté fresh spinach until just wilted. Season it with a splash of toasted sesame oil, a dash of soy sauce (or tamari for gluten-free), and a generous sprinkle of toasted sesame seeds. This simple yet elegant filling offers a delicate flavor and tender texture.
- Crisp Diced Cucumber: For a refreshing and light filling, finely dice a Persian or English cucumber. Its crisp texture and mild flavor provide a delightful contrast, especially when paired with a touch of seasoning or a creamy vegan mayo.
- “Watermelon Tuna” from Poke Bowls: Get adventurous with a unique and surprisingly convincing seafood alternative. Use the “watermelon tuna” recipe from these vegan poke bowls. The preparation transforms watermelon into a texture and appearance similar to raw tuna, offering an exciting and innovative filling option.
Storing Your Homemade Onigiri
While onigiri are truly a delight when enjoyed fresh, straight after preparation, you can certainly store them for later. The ideal scenario is to consume them within a few hours of making them, as the rice retains its optimal texture and the nori its crispness. If you need to store them, wrap each onigiri individually and tightly in plastic wrap to prevent the rice from drying out. They will keep well in the refrigerator for up to one day. Please note that the nori seaweed may lose some of its crispiness and become slightly softer after refrigeration, but the onigiri will still be delicious. I do not recommend freezing this recipe, as the texture of the rice can become undesirable after thawing, losing its characteristic chewiness and potentially becoming crumbly.

Pin Recipe
Leave a Review
Ingredients
- 400 g sushi rice/Japanese short grain rice
- 1 tablespoon furikake seasoning
- About ½ cup vegan chickpea tuna, see note
- Water
- Sea salt
- Several strips of roasted nori
Instructions
- Place the sushi rice in a large bowl and cover with cold water. Gently swirl the rice with your hand, then drain the water. Repeat this process 3-4 times until the water runs clear. This step is essential to remove excess starch and prevent the rice from becoming too sticky.
- Transfer the washed rice to a rice cooker. Add the appropriate amount of water (refer to your rice cooker’s instructions, typically it’s a 1:1.25 ratio of rice to water). Let the rice cook until done.
- Once the rice has cooled slightly but is still warm, transfer it to a large bowl. Gently fold in the furikake seasoning, ensuring it’s evenly distributed. Adjust the amount of furikake to taste.
- If you haven’t already made the vegan chickpea tuna, prepare it according to the recipe linked here. Ensure it’s chilled before using it as a filling.
- Wet your hands with a little water and sprinkle with a pinch of sea salt. This prevents the rice from sticking to your hands and adds a bit of flavor. Scoop about 1-2 tablespoons of seasoned rice into your palm, then slightly flatten it to form a small patty. Place about 1 teaspoon of the vegan chickpea tuna filling in the center of the rice.
- Cover the filling with an equal amount of rice, then gently press and shape the rice into a triangle or ball, ensuring the filling is completely enclosed. Press firmly but gently to compact the rice without crushing it.
- Cut the roasted nori into strips (around 1/3 of the perforated strip found in most nori packages). Wrap a strip of nori around the bottom of each onigiri, pressing it slightly to adhere. The nori strip helps hold the shape of the onigiri and adds a nice flavor and texture.
- Repeat the process with the remaining rice and filling, adjusting the amount of filling and rice according to your preference. Serve the onigiri immediately, or wrap them individually in plastic wrap and store them in the refrigerator for up to a day.
Notes
- Vegan Chickpea Tuna: This versatile and flavorful filling can be prepared ahead of time and stored in the refrigerator, making your onigiri assembly even quicker. It offers a wonderful texture and savory taste that perfectly complements the seasoned rice.
- Furikake Seasoning: When selecting furikake, ensure it aligns with your dietary needs. Many varieties contain sesame seeds, seaweed, and salt, but some may include dried fish or egg. Look for specifically labeled vegan options to ensure your onigiri are entirely plant-based.
- Serving Suggestions: Onigiri are incredibly flexible! Enjoy them as a quick, satisfying snack, pack them into a vibrant bento box for lunch, or serve them as part of a light and refreshing meal. They are also fantastic for picnics, road trips, and any occasion where you need a convenient, delicious, and mess-free bite.
- Storage: For the best experience, consume your onigiri immediately after preparation, when the rice is perfectly moist and the nori is crisp. If storing, wrap each rice ball tightly in plastic wrap to prevent drying. They will remain fresh in an airtight container in the refrigerator for up to 24 hours. Be aware that the nori may soften slightly upon refrigeration, but the flavors will still be delightful.
