Miso Marinated Salmon Onigiri

Have you ever tried miso-zuke?

Today, I'm sharing Miso-Marinated Salmon Onigiri. The savory salmon pairs perfectly with warm Japanese rice! And the best part? These onigiri are freezer-friendly. 🍙

Miso-zuke is a traditional Japanese method of marinating vegetables, meat, or fish in miso. While it was originally used to help preserve food, it also infuses ingredients with a rich miso aroma and enhances their natural flavor.

When fish or meat is marinated in miso, the umami becomes more concentrated, and the texture stays wonderfully moist and tender after cooking.

What is Miso ?

Miso is a traditional Japanese seasoning made from fermented soybeans, salt, and kōji (a fermented rice or grain culture).  The ingredients are mixed together and aged for months to develop a deep, savory umami flavor.  It’s commonly used in miso soup, marinades, sauces, and many Japanese home-cooked dishes.　Miso isn't just delicious—it may also offer some great health benefits, including supporting gut health, promoting healthy skin, and helping support overall wellness.

And when salmon is marinated in miso, it becomes wonderfully moist and flavorful, with a rich savory aroma that makes it even more delicious.

✨ Tips for success

• Use the freshest salmon fillets you can find.

• The longer the salmon marinates, the better the flavor. 

• Wipe off the miso thoroughly before cooking, as it burns very easily.

• Cook over low heat with a lid on, turning once to cook both sides evenly. This gentle steaming method helps keep the salmon moist and tender.
