Salmon Onigiri Ingredients

For the Onigiri
• Leftover Salmon – Provides the main protein and flavor; can substitute with canned salmon.
• Leftover Cooked Rice – Forms the base of the onigiri, providing energy and texture; freshly steamed rice can also be used.
• Rice Vinegar – Used to season the rice, enhancing flavor; can substitute with apple cider vinegar.
• Mirin – Sweet rice wine that adds sweetness and a hint of acidity; substitutes include honey or sugar mixed with water.
• Kewpie Mayo – Adds creaminess and richness to the filling; regular mayonnaise is a suitable alternative.
• Sriracha – Offers a spicy kick to the salmon filling; adjust according to your heat preference.

For Cooking
• Sesame Oil – Used for pan-frying to achieve a crispy texture; any neutral oil can be used in its place.

For Serving
• Nori Sheets – Wraps around the onigiri for added flavor; cut into strips for serving or leave out if avoiding seaweed.
• Furikake (optional) – A topping for extra flavor and texture; optional but highly recommended for authenticity.

These ingredients come together to create the perfect Salmon Onigiri, turning your leftovers into an exciting meal!

How to Make Salmon Onigiri

Prepare the Salmon: Flake your leftover salmon into a bowl, then stir in Kewpie mayo and sriracha until blended. This creamy filling is the heart of your onigiri, packed with flavor.
Season the Rice: Warm the leftover cooked rice in a microwave or over low heat. Stir in rice vinegar and mirin until everything is well combined. The rice should be lightly sticky yet fluffy, perfect for molding.
Shape the Onigiri: Wet your hands to prevent rice from sticking. Grab a handful of seasoned rice and form it into a triangle. Create a small well in the center, then fill it with the creamy salmon mixture and encase it with more rice.
Pan-Fry Onigiri: Brush the shaped onigiri with sesame oil and pan-fry in a skillet over medium heat. Cook until they are golden brown and crispy on all sides—about 3-4 minutes per side.
Wrap with Nori: Once browned, remove from the skillet and wrap each onigiri with nori strips. The nori adds a wonderful flavor contrast to the crispy rice.
Garnish (optional): If you wish, sprinkle sesame seeds over the onigiri for an extra layer of flavor and texture. A dash of taste that elevates this delightful dish!

Optional: Serve with soy sauce or extra spicy mayo for dipping to enhance those flavors even more!

Expert Tips for Salmon Onigiri

Use Fresh Rice: Cold, leftover rice can easily become too firm. Try to use rice that’s just warm for better molding and texture.
Adjust Spice Level: Sriracha can be spicy! Start with a small amount in the salmon filling, then taste and adjust to suit your preference; nobody wants an overpowering heat in their salmon onigiri.
Moisten Your Hands: Keep your hands damp while shaping the onigiri. This simple trick prevents rice from sticking and makes for easier handling while ensuring a perfect shape.
Fry on Medium Heat: Cooking on too high of a heat can result in burnt exteriors while leaving the inside cold. Medium heat is ideal for achieving that golden, crispy crust.
Experiment with Fillings: Don’t hesitate to get creative! Substitute salmon for other proteins or add vegetables for a different twist on the classic salmon onigiri.

How to Store and Freeze Salmon Onigiri

Fridge: Store leftover Salmon Onigiri in an airtight container for up to 2 days. This helps maintain their texture, but they are best enjoyed fresh.
Freezer: For longer storage, freeze the onigiri in a single layer on a baking sheet, then transfer them to an airtight container or freezer bag for up to 1 month.
Reheating: Reheat in a skillet over medium heat to restore crunchiness, or use the microwave for about 30 seconds; a quick pan sear after microwaving revives that crispy texture.
Avoid Moisture: Keep the onigiri wrapped in paper towels if storing them, as excess moisture can make them soggy, especially in the fridge.

Make Ahead Options

These Salmon Onigiri are a fantastic choice for meal prep enthusiasts! You can prepare the salmon filling and season the rice up to 24 hours in advance by refrigerating them separately in airtight containers. The rice should be kept slightly warm or at room temperature to maintain its fluffy texture. When you’re ready to serve, simply reshape the rice and fill it with the already prepared salmon mixture before pan-frying. This not only saves time but ensures that every bite is just as delicious as if you made it fresh. Enjoy your fantastic homemade onigiri with less hassle, perfect for busy weeknights!

Salmon Onigiri Recipe FAQs

How do I choose ripe and fresh salmon for my onigiri?
Absolutely! When selecting salmon, look for vibrant colors and a fresh, ocean-like smell. Avoid any dark spots or dryness on the flesh, as these are signs that the salmon has been sitting too long. If using canned salmon, opt for a brand that packs its fish in water or oil without additional preservatives for the best flavor.

What is the best way to store leftover Salmon Onigiri?
Very! To keep your delightful Salmon Onigiri fresh, store them in an airtight container in the refrigerator for up to 2 days. If possible, place a paper towel in the container to help absorb excess moisture, which can make the onigiri soggy. They taste best when enjoyed fresh, so consider making smaller batches if you anticipate leftovers.

Can I freeze Salmon Onigiri, and how?
Absolutely! Freezing them is a great idea for meal prep. First, lay the formed onigiri in a single layer on a baking sheet lined with parchment paper. Freeze them for about an hour until firm, then transfer them into an airtight container or freezer bag. They can be stored in the freezer for up to 3 months. When you’re ready to eat, thaw them in the fridge overnight and reheat in a skillet for that crispy texture!

What if my onigiri falls apart during cooking?
Very! If your onigiri isn’t holding together, it could be due to using cold rice or not enough rice in the shaping process. Always use slightly warm, sticky rice, and ensure you’re compressing the rice firmly while shaping. A mold can help with the forming process too; if you’re having trouble, consider using one.

Is there a dietary consideration for pets regarding leftovers?
Absolutely! While leftover salmon can be a treat for dogs, always ensure it’s cooked and free of bones before sharing. Avoid giving salmon onigiri to pets because of ingredients like mayonnaise and sriracha, which can be harmful to them. Always check with your vet if you’re unsure about introducing new foods!

Can I modify the spices in the salmon filling?
Of course! Feel free to adjust the sriracha amount in the salmon mixture according to your family’s heat preference. If someone prefers milder flavors, you can skip the sriracha altogether, or use a dash of lemon juice or a sprinkle of herbs for an added zing without the heat.
