To understand this dish, you have to think of it as a warm sushi salad in casserole form. Unlike traditional nigiri or maki, which are served cold and require precise rolling techniques, a sushi bake is intentionally rustic and approachable. It consists of a thick layer of vinegared sushi rice that acts as the foundation. This base is often seasoned with furikake—a dry Japanese seasoning usually containing seaweed flakes, sesame seeds, and dried fish—before being topped with a luscious mixture of cooked seafood and creamy binders.
