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.
