The Best Sushi Bake Recipe

If you love sushi but want something easier to assemble at home, this sushi bake is a perfect solution. Think of it as a deconstructed sushi roll: seasoned sticky rice baked briefly, topped with furikake and chunks of salmon, then finished with fresh avocado, green onions, and a drizzle of flavorful mayo. It’s approachable, comforting, and ideal for serving to a crowd or enjoying as a special meal at home.

This version is fully cooked, making it a good pick for anyone who prefers or needs cooked fish. The flavors are familiar — rice seasoned with rice vinegar and sugar, a sprinkle of furikake for umami, and a finishing touch of creamy kewpie or spicy mayo. The result is a rich, satisfying bite that captures the essence of sushi without rolling or raw handling.

What You Will Need

  • Rice vinegar, sugar, & kosher salt – whisk these together to season the sticky rice.
  • White sticky rice (sushi or short-grain rice) – cook according to package directions; use a rice cooker or stovetop.
  • Furikake seasoning – a savory Japanese sprinkle that adds extra depth to the rice.
  • Fresh salmon – you can use thawed frozen salmon if needed; remove skin and cut into cubes before baking.
  • Avocado & green onions – sliced and added after baking for freshness and texture.
  • Kewpie mayo & garlic chili sauce – use kewpie for a creamy finish or blend mayo with chili sauce for spicy mayo.
  • Nori sheets – cut into small squares for serving pieces of sushi bake.
  • Garnish – sesame seeds, pickled ginger, and optional sriracha or soy sauce for serving.

How To Make Sushi Bake

Start by preheating the oven and preparing the rice. Spread cooked sticky rice into an even layer in a quarter baking sheet or similar shallow casserole dish. In a small bowl, whisk together rice vinegar, granulated sugar, and kosher salt, then pour the mixture evenly over the rice. Using wet fingers, press the rice gently into the pan so it holds together. Bake uncovered until the top is slightly golden, about 10–15 minutes at 475°F.

When the rice has cooled enough to handle, sprinkle furikake evenly across the surface. Cut the salmon into roughly 1-inch cubes and remove any skin. Arrange the salmon pieces in a single layer over the seasoned rice and season lightly with kosher salt and black pepper.

Reduce the oven temperature to 400°F and return the pan to bake until the salmon is cooked through, about 12–15 minutes depending on the size of the cubes. Remove from the oven and let the pan cool briefly so the salmon and rice settle before adding toppings.

Top the slightly cooled salmon and rice with sliced avocado, cucumber or cucumber ribbons, sliced green onions, and a drizzle of kewpie or spicy mayo. Sprinkle sesame seeds and add a small amount of pickled ginger on the side if you like a palate cleanser between bites. For a touch of heat, finish with sriracha or a thin drizzle of chili sauce.

Best Ways To Serve A Sushi Bake

Cut the finished sushi bake into small squares and place each on a 2-inch square of nori. Add any extra toppings you prefer before eating: a small spoonful of soy sauce or tamari for a gluten-free option, more kewpie or spicy mayo, or a tiny drizzle of eel sauce if you have it. You can also swap the salmon for imitation crab, cooked real crab, or raw tuna; just note that raw options would not need the final bake step.

  • 5 cups sticky rice (cooked)
  • 1½ pounds salmon fillets (skin removed, cut into 1-inch cubes)
  • 2 tablespoons furikake

Instructions

  1. Prep: Preheat the oven to 475°F.
  2. Bake rice: Whisk the rice vinegar, sugar, and kosher salt together. Spread 5 cups of cooked sticky rice evenly in a nonstick quarter baking pan.
