  • Total Time: 30 minutes
  • Yield: 4 servings (20 pieces)

Ingredients

For the Rice Layer

  • 1.5 cups uncooked short-grain rice (or 4 cups / 800 g cooked short-grain rice)
  • 1 tbsp rice vinegar (or apple cider vinegar or white vinegar)
  • 2 tsp white granulated sugar
  • 1/2 tsp salt
  • 1 tsp vegetable oil (or any neutral oil, for greasing the baking dish)
  • 1 tsp sesame seeds (optional)
  • 1 tbsp furikake (optional)

For the Spicy Tuna Layer

  • 15.87 oz canned tuna in oil (or canned tuna in water or canned salmon, 3 x 5.29 oz / 150 g cans)
  • 4-5 tbsp Japanese mayo (or regular mayo)
  • 1-2 tbsp sriracha
  • 1/4 tsp salt

For the Toppings

  • 4 medium avocado (ripe)
  • 2-3 tbsp Japanese mayo (or regular mayo)
  • 2-3 tbsp sriracha
  • 10 sheets nori (cut in half to make 20 sheets)
  • 1 green onion (finely chopped for garnishing)

Instructions

  1. Prepare Baking Dish: Evenly grease a 9 x 9-inch baking dish with vegetable oil or any neutral oil using a paper towel to prevent sticking.
  2. Cook Rice: Cook the short-grain rice according to the package instructions, either using a rice cooker or stovetop method, until fluffy and fully cooked.
  3. Preheat Oven: Set the oven to broil at 500 degrees Fahrenheit to prepare for baking the sushi bake.
  4. Season Rice: Transfer the hot cooked rice to a large bowl. Add salt, sugar, and rice vinegar, then mix well with a rice paddle or wooden spoon. Spread the seasoned rice evenly and firmly into the greased baking dish.
  5. Add Toppings to Rice: Sprinkle sesame seeds and furikake evenly over the seasoned rice layer for added flavor and texture.
  6. Make Spicy Tuna Mixture: Open canned tuna and drain excess liquid using a fine sieve and fork. In a medium bowl, combine the drained tuna with Japanese mayo, sriracha sauce, and salt. Mix until well incorporated, then evenly spread this spicy tuna mixture over the rice layer.
  7. Prepare Avocado: Peel and thinly slice ripe avocados. Layer the avocado slices evenly over the spicy tuna layer in the baking dish.
  8. Drizzle Sauce: Generously drizzle Japanese mayo and sriracha sauce over the avocado to add creaminess and spice.
  9. Broil: Place the baking dish in the preheated oven and broil for 10 minutes, or until the sauce is bubbling and has turned golden brown.
  10. Garnish and Serve: Remove the dish from the oven, sprinkle finely chopped green onions on top, and let it cool slightly. Slice the sushi bake with a wet knife into 20 pieces. Scoop a portion of the mix onto small nori sheets and enjoy your sushi bake!

Notes

  • If you do not have a rice cooker, cook the rice on the stovetop by bringing water and rice to a boil, then simmering on low heat covered until water is absorbed (about 15 minutes).
  • Use Japanese mayo like Kewpie for authentic flavor, but regular mayo works well too.
  • Adjust the amount of sriracha sauce to control the spice level.
  • For a lower fat version, opt for tuna canned in water instead of oil and reduce mayo quantity.
  • Using a wet knife when slicing prevents the rice from sticking and helps in clean cuts.
  • Furikake adds a great umami flavor but is optional if unavailable.
