Ingredients for Tuna Rice Bowls
These core ingredients create the perfect balance of creamy, salty, spicy, and tangy. Use fresh ingredients when possible to elevate the overall texture and flavor.
Base:
- 2 cups Cooked White Rice
Japanese short grain or medium grain rice is preferred for its sticky texture and ability to hold toppings well. Warm rice works best—it softens the tuna mix and blends flavors.
Tuna Mixture:
- 1 can (5–6 oz) Tuna, Oil-Packed
Oil-packed tuna has richer flavor and better texture, but water-packed can also be used. Drain thoroughly. If using fresh tuna (sashimi grade), cut into small cubes and marinate briefly in soy sauce and sesame oil. - 2 tablespoons Japanese Mayonnaise (Kewpie)
Kewpie adds more umami and creaminess than regular mayo due to the presence of egg yolk and rice vinegar. If unavailable, regular mayo can be used. - 1–2 teaspoons Sriracha Sauce
Adjust depending on your spice preference. Adds a subtle heat that balances the richness of the mayo. - 1 teaspoon Soy Sauce
For salt and deep umami. Avoid overdoing it, as too much liquid can make the tuna mixture watery. - 1 teaspoon Toasted Sesame Oil
Just a touch adds nutty, roasted aroma. Do not substitute with regular sesame oil—it lacks depth. - 1 teaspoon Rice Vinegar
Brightens the tuna mix, cutting through the richness. Can substitute with apple cider vinegar if needed, but rice vinegar is milder and traditional.

Optional Toppings:
- 1/2 Cucumber, thinly sliced or julienned
Offers crunch and a clean, fresh taste. - 1 sheet Nori Seaweed, cut into thin strips or small squares
Adds a savory ocean flavor. Optional but highly recommended. - 1 tablespoon Furikake (optional)
A Japanese rice seasoning made with seaweed, sesame seeds, and sometimes bonito flakes. Adds texture and flavor in one sprinkle. - 1 Scallion (Green Onion), finely sliced
Adds sharpness and a fresh bite on top of the creamy tuna. - 1 teaspoon Black or White Sesame Seeds
Great for garnishing. Toast them lightly for added depth.
Variations for Tuna Rice Bowls
This recipe welcomes creative changes, making it easy to adjust based on what you have on hand or personal dietary preferences.
- Make it a Spicy Tuna Poke Bowl: Use raw, sushi-grade tuna and marinate briefly in soy sauce and sesame oil. Then mix with sriracha mayo as above.
- Add Avocado: Cubed or sliced avocado offers buttery richness that pairs perfectly with the spicy mayo tuna.
- Use Brown Rice or Quinoa: For added fiber or a lower glycemic index option.
- Add Kimchi or Pickled Veggies: These introduce a fermented tang that balances the creamy elements.
- Tropical Option: Add cubed mango for a sweet contrast.
- Low-Carb Version: Serve the tuna mixture over cauliflower rice or spiralized cucumber noodles.
How to Make Tuna Rice Bowls – Step-by-Step Instructions
1. Cook the Rice (if not using pre-cooked)
- Rinse 1 cup of short-grain white rice under cold water until the water runs clear. This removes excess starch and prevents clumping.
- Add to a rice cooker or small saucepan with 1¼ cups water. Cook according to your device’s instructions or bring to a boil, then reduce heat and cover. Simmer on low for 15 minutes. Let sit covered for 5 minutes, then fluff with a fork.
- Keep rice warm until ready to serve.
Tip: For meal prep, you can cook the rice ahead of time and store it in the fridge. Reheat with a splash of water to soften.
2. Prepare the Tuna Mixture
- Open and drain the tuna completely. Press lightly with a fork or spoon to remove excess oil or water.
- In a medium mixing bowl, combine:
- 1 can of tuna
- 2 tablespoons Kewpie mayonnaise
- 1–2 teaspoons sriracha (adjust to taste)
- 1 teaspoon soy sauce
- 1 teaspoon toasted sesame oil
- 1 teaspoon rice vinegar
- Mix gently with a fork until the tuna is evenly coated and creamy but not overly wet.
Pro Tip: Don’t overmix—the tuna should still have texture, not turn into a paste.

3. Slice and Prep Toppings
- Thinly slice cucumber and scallions.
- If using nori sheets, stack and cut into thin strips or small squares with clean scissors.
- Toast sesame seeds in a dry pan over medium heat for 2–3 minutes, stirring often, until fragrant.
4. Assemble the Bowls
In each serving bowl, layer the ingredients in the following order:
- Base Layer: Spoon about 1 cup of warm cooked rice into each bowl.
- Tuna Mix: Add a generous scoop of your prepared tuna mixture.
- Fresh Toppings: Arrange sliced cucumber, scallions, and avocado (if using) around or over the tuna.
- Flavor Boosts: Sprinkle with sesame seeds, nori strips, or furikake seasoning.
- Extra Drizzle: For more heat, add a light swirl of sriracha or a drizzle of soy sauce.
Presentation Tip: Keep the toppings separated in sections for a clean, colorful look.
Serving and Decoration
These bowls are visually appealing and taste even better when warm rice contrasts with cool toppings. For a beautiful finish:
- Add thin avocado slices arranged in a fan shape.
- Place cucumber in ribbon shapes.
- Sprinkle everything lightly with toasted sesame seeds.
Pair it with miso soup or a side of pickled ginger for a complete meal.
Storing Tuna Rice Bowls
Refrigeration:
- Store the tuna mixture in an airtight container for up to 3 days.
- Cooked rice can be stored separately for up to 4 days.
- Keep vegetables like cucumbers or avocado unmixed and slice fresh when serving to avoid sogginess or browning.
Reheating:
- Gently reheat rice in the microwave with a splash of water to restore moisture.
- Do not reheat the tuna mixture—serve it cold over warm rice for best results.
Tips and Tricks for Success
- Use Warm Rice: The contrast between warm rice and chilled tuna creates a more satisfying texture and enhances flavor.
- Drain Tuna Thoroughly: Excess moisture can water down the creamy sauce. Press tuna gently after draining to remove liquid.
- Balance the Sauce: Start with less sriracha if you’re unsure about heat levels. You can always add more later.
- Use Kewpie Mayo if Possible: Its rich, egg-yolk base gives the tuna mixture a smoother and deeper flavor.
- Toast Your Sesame Seeds: Just a quick dry-toast in a pan will enhance their flavor and aroma dramatically.
- Customize to Taste: These bowls are flexible. Add crunchy carrots, pickled onions, or even edamame for more variety.
