How to Make Sushi Sandwiches (Onigirazu)

Prepare Sushi Rice: Start by rinsing the sushi rice under cold water until the water runs clear; this removes excess starch. Soak for about 30 minutes, then boil and simmer according to package directions until fluffy.
Flavor Rice: Once the rice is cooked, gently fold in a mixture of rice vinegar, granulated sugar, and kosher salt. This step will enhance the flavor and sticky texture; let the rice cool slightly.
Season Salmon: Take your skinless salmon and lightly season with salt. If you prefer a cooked option, pan-sear for about 2-3 minutes per side until fully cooked, or leave it raw if it’s sushi-grade.
Setup Workstation: Place nori sheets shiny side down on a clean, flat surface or bamboo mat. This will be the base for your sushi sandwich.
Layer Ingredients: In the center of each nori sheet, spread a generous amount of warm sushi rice. Top with the seasoned salmon, avocado slices, refreshing cucumber, grated carrot, and crunchy purple cabbage.
Wrap: Fold the nori edges over the filling to form a square-shaped wrap, making sure to seal the edges tightly. Cut in half for serving, and enjoy your sushi sandwiches!

Optional: Serve with a drizzle of extra sriracha for added heat.

How to Store and Freeze Sushi Sandwiches

Room Temperature: Sushi sandwiches are best enjoyed fresh, but if left out, consume within 2 hours to ensure optimal taste and safety.
Fridge: Store leftover sushi sandwiches in an airtight container for up to 2 days. To maintain freshness, keep nori separate if possible, wrapping just before eating.
Freezer: For long-term storage, individually wrap sushi sandwiches in plastic wrap and then place in a freezer-safe bag. They can last up to 1 month; thaw in the fridge overnight before consuming.
Reheating: If you prefer warm sushi sandwiches, briefly heat them in a microwave (wrapped in a damp paper towel) for 15-20 seconds on low. Enjoy your sushi sandwiches at your own pace!

Sushi Sandwiches (Onigirazu) Recipe FAQs

How do I choose the right salmon for sushi sandwiches?
Absolutely! When selecting salmon, it’s best to opt for sushi-grade fish, which is specifically prepared for raw consumption. Look for vibrant color and a fresh, ocean-like smell. If it has a dull color or any unpleasant odor, it may not be the best choice. Always source your salmon from reputable suppliers, and if you’re cooking it, any fresh, high-quality salmon will work wonderfully.

How should I store leftover sushi sandwiches?
For sure! Store leftover sushi sandwiches in an airtight container in the fridge, where they’ll stay fresh for up to 2 days. If possible, keep the nori sheets separate from the fillings to prevent them from becoming soggy. When you’re ready to enjoy your leftovers, just wrap the nori just before eating for that crisp texture!

Can I freeze sushi sandwiches?
Yes, you absolutely can! To freeze sushi sandwiches, wrap each one tightly in plastic wrap and place them in a freezer-safe bag. They can be stored for up to 1 month. For the best experience, simply thaw them in the fridge overnight before consuming. If you like, you can even warm them up in the microwave (wrapped in a damp paper towel) for a cozy bite!

What can I do if my sushi rice is too sticky or dry?
Very common! If your sushi rice is too sticky, it might be due to excess water during cooking. Ensure you rinse it until the water runs clear before cooking. If it’s too dry, consider adding a tiny splash of water and microwaving it for a few seconds to rehydrate. The texture should be just right for molding into your sushi sandwiches!

Are there any dietary considerations I should keep in mind?
Absolutely! If preparing sushi sandwiches for someone with dietary restrictions, be mindful of allergens such as seafood, soy (in soy sauce), and gluten (in soy sauce and nori). You can easily switch to gluten-free tamari and use tofu for a vegetarian version. Always communicate with your guests about their preferences and allergies to ensure everyone enjoys this delicious meal without worries!
