- Step 4: Sprinkle the sesame seeds and furikake evenly over the rice layer.
- Step 5: Drain the canned tuna thoroughly using a fine sieve and a fork. Transfer to a medium bowl and mix with 4-5 tablespoons Japanese mayo, 1-2 tablespoons sriracha, and 1/4 teaspoon salt. Spread this spicy tuna mixture evenly over the rice.

- Step 10: Using a wet knife, slice the sushi bake into 20 pieces. Scoop a portion of the filling into a small sheet of nori and enjoy immediately.
Tips & Variations
- For a milder version, reduce the sriracha to your preferred heat level or omit it altogether.
- Try substituting canned salmon for tuna for a different flavor.
- If you don’t have furikake, you can sprinkle additional sesame seeds or chopped seaweed flakes for added texture.
- Use leftover cooked rice to make this dish even quicker to prepare.
Storage
Store leftovers covered in the refrigerator for up to 2 days. Reheat gently in the oven or microwave until warmed through. For best texture, avoid storing avocado-topped layers for too long as the avocado may brown.

FAQs
Can I use different types of rice for this recipe?
Short-grain rice works best for sushi bake because of its sticky texture. Using long-grain rice may result in a less cohesive dish.
Is there a way to make this gluten-free?
Yes. Use gluten-free mayonnaise and check that the sriracha and furikake you use do not contain gluten-containing ingredients.
