Baking Instructions

  • Cook sushi rice according to your preferred method and season appropriately. Cover with a damp cloth if not using immediately.
  • Preheat oven to 350°F (175°C). Season salmon with salt and pepper and bake for 10 minutes. Salmon should be slightly undercooked inside.
  • Flake the baked salmon and place it in a large mixing bowl.
  • Add flaked imitation crab, chopped scallions, and half of your spicy mayo or preferred mayo blend to the salmon. Mix until combined.
  • Increase oven temperature to 375°F (190°C). Spread cooked rice evenly in a 13x9 inch baking dish.
  • Sprinkle a generous layer of furikake over the rice.
  • Evenly spread the salmon and crab mixture over the furikake rice layer. Smooth with a spatula.
  • Drizzle unagi sauce and additional mayo of choice over the top. Sprinkle more furikake if desired.
  • Bake for 10 minutes, then broil on top rack for 2–3 minutes until lightly browned and bubbly. Alternatively, use a kitchen torch to finish.
  • Garnish with remaining scallions and optional toppings like fish roe, avocado, or tempura bits. Serve warm with roasted seaweed sheets.

Notes

  • Kewpie mayo gives the best flavor, but regular mayo can be substituted if needed.
  • For a make-ahead option, assemble the dish in advance and bake when ready to serve.
  • You can adjust mayo ratios to balance heat and citrus flavor depending on your preference.
  • This recipe is great for meal prep—leftovers reheat well in an oven or air fryer.
