Variations

Brown Rice or Quinoa: Swap sushi rice for brown rice or quinoa for a fiber-rich option.
Add Crunch: Top with crispy fried onions, nori strips, or tempura bits for extra texture.
Vegan Option: Use mashed chickpeas or tofu in place of tuna and vegan mayo.
Spice Level Control: Adjust the amount of sriracha or replace with chili oil or gochujang.

Storage/Reheating

This rice bowl is best served immediately for optimal texture and freshness. If storing, keep components separate in airtight containers in the refrigerator for up to 1 day. Reheat the rice separately and assemble just before serving. Avoid microwaving the spicy mayo tuna to preserve its creamy texture.

FAQs

What type of tuna should I use?

Use high-quality canned tuna in water or oil, depending on your preference. Drain thoroughly before mixing.

Can I use regular mayonnaise instead of Kewpie?

Yes, but Kewpie mayonnaise adds a richer, umami flavor. You can mimic it by mixing regular mayo with a touch of rice vinegar and sugar.

Is this dish spicy?

It has a moderate level of heat from sriracha. Reduce or omit the sriracha for a milder version.

Can I prepare this ahead of time?

You can prep components like rice, tuna mix, and chopped vegetables ahead. Store separately and assemble before eating.

What’s the best rice for this bowl?

Sushi rice is ideal for its sticky texture, but jasmine or short-grain white rice also works well.

Can I use fresh tuna instead of canned?

Yes, you can use raw sushi-grade tuna diced finely, but it should be kept cold and consumed immediately.

Is this gluten-free?

Use gluten-free sriracha and soy sauce (if adding) to ensure the dish is gluten-free.

How do I keep the avocado from browning?

Add avocado just before serving or toss slices in lemon juice to slow oxidation.

Can I make this bowl low-carb?

Yes, replace the rice with cauliflower rice or shredded cabbage for a low-carb alternative.

Are there other sauces I can use?

Yes, drizzle with ponzu, soy sauce, or a sesame-ginger dressing for a different flavor profile.
