Crispy, buttery rice, creamy filling, this Creamy Crab Onigiri Rice Ball is the perfect recipe for summer picnics!
Creamy Crab Onigiri is stuffed with creamy, sweet, and savory crab, and the rice is pan-fried till crispy with butter and soy sauce.
It takes less than 15 minutes to make; my Creamy Crab Onigiri has been a favorite household lunch this summer.
All you need to make this delicious Creamy Crab Onigiri is rice, imitation crab or fresh crab, Japanese mayo, green onion, sweet corn, and if you like it spicy, a little bit of Korean red chili paste.
I love adding sweet corn to give it a nice crunch, and it also adds sweetness to the creamy crab onigiri. You can customize your Onigiri to your liking; I have a super CREAMY tuna rice ball that is delicious and takes less than 15 minutes.
To save time and make perfect Creamy Crab Onigiri every single time, I am using a Triangle Onigiri Mold.
Onigiri molds are affordable ($7) and are super convenient for quick and easy lunches.
Using a mold, you can ensure that the rice is tightly packed and doesn’t fall apart. If you don’t have a mold, you can also use your hands instead.
Quick tip – to prevent the rice from sticking to your hands, make sure to wet your hands with water first.
It is OPTIONAL but HIGHLY recommended to pan-fry the Creamy Crab Onigiri in butter.
It gives the rice ball a crispy texture on the outside but soft and creamy on the inside.
I am using butter and a teaspoon of soy sauce to save time, but another delicious option is to use my homemade lemon Miso Butter to give it even more umami flavors!
