What you will need

This recipe uses 8 simple ingredients that you can find at any grocery store:

  • 2 cups cooked short-grain sushi rice, cooled
  • 2 rice vinegar
  • 8 oz sushi-grade tuna, finely diced
  • 3 tbsp Japanese mayonnaise
  • 2 tbsp sriracha sauce
  • 1 tbsp soy sauce
  • 2 tbsp sesame oil
  • 2 tbsp toasted sesame seeds

Step by step instructions

Step 1: Season and Chill the Rice

Mix cooled sushi rice with rice vinegar until well combined. Press the rice firmly into a parchment-lined baking dish to about 1 inch thickness. Refrigerate for at least 1 hour or until very firm so it holds its shape when cut.

Step 2: Cut and Fry the Rice Cakes

Remove chilled rice from the dish and cut into 12 equal rectangles. Heat sesame oil in a large non-stick skillet over medium-high heat until shimmering. Fry rice cakes in batches for 3 to 4 minutes per side until deeply golden and crispy on both sides. Transfer to a paper towel-lined plate.

Step 3: Make the Spicy Tuna Mixture

Combine diced sushi-grade tuna with Japanese mayonnaise, sriracha, and soy sauce in a chilled mixing bowl. Stir gently to coat all the tuna without breaking it down too much. Taste and adjust sriracha for your desired heat level.

Step 4: Assemble the Bowls

Arrange 3 crispy rice cakes per serving on each bowl or plate. Spoon a generous tablespoon of the spicy tuna mixture on top of each crispy rice piece. Press lightly so the topping adheres without falling off.

Step 5: Garnish and Serve

Sprinkle toasted sesame seeds over each assembled crispy rice bite. Serve immediately while the rice remains crispy and the tuna stays cold for the best textural contrast. Add sliced avocado or cucumber on the side if desired.

Easy substitutions

Missing an ingredient? Here are some swaps that work perfectly:

  • sushi-grade tuna → canned premium tuna packed in oil, well drained and flaked
  • Japanese mayonnaise → regular mayonnaise mixed with a small squeeze of lemon juice
  • short-grain sushi rice → leftover jasmine rice packed very tightly into the mold

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Not chilling the rice long enough before cutting which causes the cakes to fall apart in the pan
  • Using freshly cooked warm rice that is too sticky and soft to hold its shape when fried
  • Crowding the pan with too many rice cakes at once which causes steaming instead of crisping
