Onigirazu (Sushi Sandwich) Ingredients
For the Sushi Rice
• Sushi Rice – Essential for the sandwich’s structure; use brown or red Thai rice for a healthier twist.
For the Protein Filling
• Tofu (Firm) – The star of the Tofu Katsu; ensure it’s pressed to absorb flavors better.
• Sweet Potato – A naturally sweet alternative that adds delightful texture; you can substitute with any starchy root vegetable.
For the Wrap
• Nori Sheets – These seaweed wraps hold everything together while imparting traditional flavor; crucial for an authentic Onigirazu experience.
Optional Topping
• Quick Pickled Red Cabbage Ingredients – Adds a refreshing crunch and acidity; feel free to substitute with any pickled vegetable.
Step‑by‑Step Instructions for Onigirazu (sushi sandwich)
Step 1: Prepare the Rice
Begin by rinsing 1 cup of sushi rice under cool water until the water runs clear, removing excess starch. In a rice cooker or pot, combine the rinsed rice with 1 ¼ cups of water, bring to a boil, reduce to low heat, cover, and simmer for about 15 minutes until soft and sticky. Once done, fluff the rice gently with a fork and let it cool slightly—this warm rice will help the nori stick.
Step 2: Press the Tofu
While the rice cooks, prepare the tofu for the Tofu Katsu filling. Wrap a block of firm tofu in clean towels and place a heavy pan on top to press out moisture. Allow it to press for about 30 minutes; you want to see water pooling around the tofu. This ensures the tofu absorbs flavors well, becoming crispy during cooking. Once pressed, slice the tofu into thick squares.
Step 3: Cook Fillings
Next, if you’re making Tofu Katsu, set up a breading station. Dredge the pressed tofu slices in flour, dip them in plant milk, and coat them with breadcrumbs. Heat a skillet over medium heat with enough oil to cover the bottom. Fry the tofu until golden brown and crispy, about 4-5 minutes per side. If you prefer the Sweet Potato filling, steam or bake a peeled and diced sweet potato until tender, about 15-20 minutes.
Step 4: Make Pickled Cabbage (if using)
For that extra tangy crunch, prepare the quick pickled cabbage. In a bowl, whisk together equal parts vinegar and water with a teaspoon of sugar and salt until dissolved. Add thinly sliced red cabbage, ensuring it’s submerged. Let it sit for at least 10 minutes for the flavors to meld while you continue with the assembly of your Onigirazu.
Step 5: Assemble Onigirazu
Lay a sheet of nori on a clean, flat surface, shiny side down. Scoop a layer of warm sushi rice onto the nori, forming a circle in the center, about the size of your palm. Place your choice of filling—either the crispy tofu or the sweet potato—and top it with a small handful of pickled cabbage if using.
Step 6: Fold and Serve
Carefully fold the edges of the nori over the fillings, like folding a burrito, tucking the sides in tightly to secure everything. Allow the Onigirazu to rest for a few moments, which helps the nori soften and adhere to the rice. Cut diagonally for a beautiful presentation, then savor your homemade Onigirazu (sushi sandwich) as a satisfying lunch alternative!
Storage Tips for Onigirazu
Fridge: Store Onigirazu in the refrigerator wrapped in plastic wrap for up to 1 day to maintain their freshness and flavor.
Freezer: For longer storage, freeze the assembled Onigirazu in airtight containers for up to 1 month. Just be aware that the texture may change upon thawing.
Reheating: When ready to enjoy, gently reheat in a microwave for about 30 seconds or heat in a skillet on low until warmed through. This ensures the rice remains tender while the nori softens.
Best Fresh: Although delicious, it’s best to consume Onigirazu (sushi sandwich) fresh to enjoy the delightful combination of crispy nori and flavorful fillings.

Expert Tips for Onigirazu
-
Pressing Tofu: Ensure tofu is well-pressed to avoid sogginess. A weight on top for at least 30 minutes will help it absorb flavors better.
-
Sushi Rice Temperature: Use warm sushi rice for easier handling. This moisture also helps the nori stick to the rice, preventing any separation.
-
Breading Technique: When frying tofu, maintain medium heat to cook it evenly. Too high heat can lead to burning, while too low may leave it soggy.
-
Nori Folding: Be gentle and precise when folding the nori around the fillings. A tight fold keeps everything secure and helps maintain the Onigirazu structure.
-
Add Pickled Veggies: Consider including pickled vegetables for extra crunch and tang. Quick pickled red cabbage pairs beautifully with the Onigirazu, balancing flavors perfectly.
-
Storage Tips: If not eating immediately, wrap each Onigirazu tightly in plastic wrap to maintain freshness. They are best enjoyed within a day.

Onigirazu (Sushi Sandwich) Recipe FAQs
How do I choose the right sushi rice for my Onigirazu?
Absolutely! Choose high-quality sushi rice, which is short-grain and has the ideal stickiness. This helps the rice hold together in the sandwich. If you want to switch things up for a healthier option, brown or red Thai rice is a great substitute!
What’s the best way to store Onigirazu?
For the freshest taste, wrap your Onigirazu tightly in plastic wrap and refrigerate for up to 1 day. This keeps them from drying out and maintains their delicious flavors. If you need to store them longer, they can be frozen in airtight containers for up to 1 month.
Can I freeze Onigirazu?
Absolutely! Simply wrap each Onigirazu tightly in plastic wrap or place them in airtight containers. When you’re ready to enjoy, allow them to thaw in the fridge overnight, then reheat them gently in the microwave for about 30 seconds or in a skillet on low heat until warmed through. This should help maintain a pleasant texture.
What should I do if my Tofu Katsu turns out soggy?
No worries! Ensure that you’ve pressed the tofu properly to remove excess moisture—using a weight for about 30 minutes can help! Cooking on medium heat also ensures even frying. If they are already soggy, try frying them again in a little hot oil to crisp up the outside.
Can I make Onigirazu for my gluten-intolerant friends?
Of course! The recipe is inherently gluten-free as long as you use gluten-free coating for the tofu and check the nori packaging to ensure it’s certified gluten-free. You can even create other fillings using gluten-free ingredients to tailor the Onigirazu to their preferences.
Is it okay for kids to eat Onigirazu?
Definitely! Onigirazu is not only fun to eat but also customizable! You can adjust the fillings to suit your kids’ tastes—how about adding avocado or a dash of their favorite sauce? Just be cautious with any choking hazards or allergies related to the ingredients you choose.
