Salmon Onigiri Ingredients

Transform your leftovers into a delightful treat!

For the Salmon Filling

Leftover Salmon – Main protein; canned salmon works well in a pinch.
Kewpie Mayo – Adds creaminess with a hint of tang; regular mayo can be used instead.
Sriracha – Provides just the right kick; adjust to taste or omit for mildness.

For the Rice Base

Leftover Cooked Rice – Use what you have on hand; freshly cooked rice is also great.
Rice Vinegar – Enhances rice flavor; apple cider vinegar can be a handy substitute.
Mirin – Brings a touch of sweetness; feel free to skip it for a non-sweet flavor.

For Pan-Frying

Sesame Oil – Ideal for achieving that crispiness; vegetable or canola oil can be used if needed.
Nori Sheets – Perfect for holding the onigiri and adds flavor; use them if you can.

Optional Flavor Boost

Furikake – A delicious Japanese seasoning sprinkle; adds an extra layer of flavor.

Step‑by‑Step Instructions for Salmon Onigiri

Step 1: Prepare Salmon Filling
Begin by flaking your leftover salmon into a medium bowl. Mix it together with Kewpie mayo and a drizzle of sriracha, adjusting the heat to your liking. This savory filling will elevate your Salmon Onigiri, so make sure to combine thoroughly until creamy. Set the mixture aside while you prepare the rice.

Step 2: Season the Rice
In a separate bowl, heat your leftover cooked rice in the microwave for about 30 seconds, just until warm. Gently fold in seasoned rice vinegar and a splash of mirin to enhance the flavor. The rice should be slightly sticky, which will help it hold together when shaping your Salmon Onigiri.

Step 3: Shape the Onigiri by Hand
Wet your hands with cold water to prevent sticking, then take a handful of the warm rice and flatten it in your palm. Place a spoonful of the salmon filling in the center, then carefully encase it with the rice, forming it into a triangle. Press gently but firmly, ensuring it’s compact and holds its shape. Repeat this process until all the rice and filling are used.

Step 4: Fill the Onigiri Mold
If you have a mold, fill it halfway with rice, pressing it down gently to create a hollow space. Spoon in the salmon filling, followed by topping it with more rice to fully encase the filling. Close the mold tightly and release the onigiri onto a plate. This technique is perfect for achieving a more uniform shape for your Salmon Onigiri.

Step 5: Pan-fry Onigiri
Heat a skillet over medium heat and add a drizzle of sesame oil once hot. Place the shaped Salmon Onigiri in the skillet and cook for about 3-4 minutes on each side, or until golden brown and crispy. Monitor closely to avoid burning, turning them gently using a spatula for an even fry that locks in the flavor.

Step 6: Wrap with Nori
Once the onigiri are beautifully crispy, cut nori sheets into strips. Simply wrap the nori around one side of each onigiri, allowing the warm rice to soften it slightly for a perfect bite. For added flair, sprinkle some furikake on top for a boost of umami, and serve immediately, ready to be enjoyed!

Make Ahead Options

These Salmon Onigiri are perfect for meal prep enthusiasts! You can prepare the salmon filling by mixing leftover salmon, Kewpie mayo, and Sriracha up to 3 days in advance and store it in an airtight container in the refrigerator. The seasoned rice can also be made ahead and stored at room temperature for about 24 hours; however, keep it covered to maintain moisture. When you’re ready to enjoy, simply warm the rice and shape it into onigiri, then pan-fry until golden brown. This way, you’ll enjoy delicious, restaurant-quality Salmon Onigiri with minimal effort, even on the busiest nights! Just remember, freshly made onigiri will taste just as delightful when prepped in advance.

Expert Tips for Salmon Onigiri

• Warm Rice: Ensure your rice is warm to help it stick together while shaping. Cold rice can be crumbly and hard to mold.

• Avoid Sticking: Wet your hands or use a damp cloth to keep rice from sticking to your fingers. This makes shaping easier and cleaner.

• Crispy Perfection: Fry until golden brown for the best texture. Keep an eye on the onigiri as they cook to prevent burning.

• Flavor Variations: Feel free to explore different fillings using leftover proteins or veggies. This way, your Salmon Onigiri stays exciting and diverse!

• Nori Wrapping: Wrap the nori just before serving to prevent it from getting soggy. It will maintain its delightful crunch!

• Experiment Gently: If trying new sauces or seasonings, start with small amounts to find the perfect balance without overpowering the salmon filling.

How to Store and Freeze Salmon Onigiri

Fridge: Keep unwrapped Salmon Onigiri in an airtight container for up to 2 days to maintain freshness.

Freezer: If you want to store them longer, freeze the onigiri in a single layer on a baking sheet, then transfer to a freezer bag, where they can last up to 1 month.

Reheating: To enjoy, thaw overnight in the fridge and pan-fry in a skillet for about 3-4 minutes on each side until heated through and crispy.

Tip: For best taste and texture, avoid refrigerating wrapped onigiri, as the nori can become soggy.

Salmon Onigiri: Flavorful Twists Await!

Feel free to let your creativity shine and make this recipe your own with a few delightful variations.

Protein Swap: Replace leftover salmon with canned tuna, crab, or even cooked tofu for a different taste and texture. Each option will lead to a unique flavor profile.
Sauce Variations: Try a drizzle of teriyaki or spicy mayo in place of Kewpie mayo for an exciting flavor twist. If you enjoy spice, go for a blend like sriracha and miso for depth.
Add Vegetables: Incorporate finely chopped vegetables like green onions, cucumber, or avocado into the filling. This enhances both crunch and nutrition, making your onigiri even more satisfying.
Gluten-Free Option: Use gluten-free soy sauce instead of regular soy sauce to make a gluten-free version without sacrificing taste. This way, everyone at the table can enjoy!
Herb Infusion: Mix fresh herbs like cilantro or chopped basil into the rice for an aromatic surprise. These fresh additions can elevate the taste, giving it a garden-fresh quality.
Spicy Heat: Kick it up a notch by adding finely chopped jalapeños or chili flakes to your salmon filling. For those who love a little fire, this will surely ignite your taste buds!
Vegan Style: Substitute the salmon with mashed avocado and seasoned chickpeas for a plant-based filling packed with protein. It’s a colorful and nutritious change!

Salmon Onigiri Recipe FAQs

How do I select the perfect leftover salmon for my onigiri?
Absolutely! Look for leftover salmon that is moist and not overly dry. It should have a pleasant, light aroma without any dark spots or off-putting smells. If you’re using canned salmon, opt for high-quality brands so it complements your onigiri perfectly.

What’s the best way to store leftover Salmon Onigiri?
I recommend storing your unwrapped Salmon Onigiri in an airtight container in the fridge. They will stay fresh for up to 2 days. If you need to keep them longer, consider freezing them in a single layer on a baking sheet. Once frozen, transfer to a freezer bag for up to 1 month.

Can I freeze Salmon Onigiri for future meals?
Yes, you can! To freeze, first, shape your onigiri then lay them on a baking sheet in a single layer. Freeze until solid, about 1-2 hours, then transfer them to a freezer-safe bag. Just remember to thaw them in the fridge overnight before pan-frying again for that crispy edges goodness!

What should I do if my onigiri falls apart while shaping?
Very common! If your onigiri crumbles, it’s likely due to using cold rice or not enough moisture. Make sure your rice is warm enough to help it stick together, and try wetting your hands more generously. You can also mix in a spoonful of extra Kewpie mayo to the rice to create a stickier texture.

Are there any dietary considerations I should keep in mind when making onigiri?
Of course! For gluten-free options, be sure to use gluten-free soy sauce and verify the ingredients of whichever sauces you add. If sharing with pets or anyone with fish allergies, always mention that salmon is the primary ingredient. Enjoy its deliciousness—just be mindful of your guests’ dietary preferences!

How long can I keep onigiri in the fridge after making them?
You can keep your homemade Salmon Onigiri for up to 2 days in the refrigerator. To keep them fresh and avoid sogginess, store them unwrapped or in a breathable container. Enjoy them within this timeframe for the best taste and texture!
