Rinse two cups of sushi rice under cold water for a minute swirling until water is mostly clear. Cook using a rice cooker or stovetop with the usual water ratio for sushi rice. When ready spread rice onto a rimmed baking sheet and gently fold in a quarter cup seasoned rice vinegar with a rice paddle. Allow rice to cool uncovered this prevents it from turning gummy in the bake.

Bake for fifteen to twenty minutes until the salmon flakes easily with a fork and reaches one hundred forty five degrees internal temp. Let cool slightly and use two forks to shred into bite size pieces.
Mix the Filling:
Combine shredded salmon chopped imitation crab Japanese mayonnaise cream cheese sriracha and soy sauce in a large mixing bowl. Stir until the mixture is uniform creamy and the flavors are fully blended. Taste and add extra sriracha or mayo if you crave saucier texture.
Assemble the Sushi Bake:
Lightly press the cooled rice into a nine by thirteen baking dish making an even layer about an inch thick. Sprinkle the entire surface with two tablespoons of furikake making sure to cover the rice edge to edge. Dollop the salmon mixture over the rice and use a spatula to gently spread it in an even layer do not pack too tightly to keep it fluffy.
Broil:

I always add extra furikake as it reminds me of my childhood lunches and brings a nostalgic umami punch to every bite. Once my niece assembled the toppings with me and declared this better than any takeout which made my day.

Storage Tips

Store any leftovers tightly covered in the fridge for up to three days. To reheat use a low oven around three hundred degrees or microwave in short bursts until just warmed through. Try not to microwave too long or the rice can dry out while the filling separates.

Ingredient Substitutions

Fresh cooked crab can replace imitation for a more delicate flavor. If you are dairy free swap the cream cheese for mashed avocado or extra mayo. No furikake available use a sprinkle of crushed roasted nori and toasted sesame seeds. Any cooked salmon including leftovers will work for the filling.

Serving Suggestions

Offer a platter of sliced cucumber and avocado plus lime wedges for squeezing. If you love variety set out both unagi sauce and extra sriracha so everyone can customize each bite. This bake pairs well with miso soup edamame or a crisp Asian slaw.
