Sushi rice forms the base of this dish. It is sticky and holds together well. It pairs perfectly with fresh, sashimi-grade tuna. The tuna gives the bowl a rich flavor. I like to mix it with mayonnaise and sriracha for a spicy kick.
Next, fresh vegetables add crunch and color. Slices of creamy avocado and crisp cucumber are my go-to choices. I also like to add julienned carrots for a little sweetness.
Finally, the toppings complete the dish. Sesame oil brings out the flavors. Green onions add a nice bite, and sesame seeds give a lovely crunch. You can even add toasted seaweed strips for extra texture.
With these ingredients, you create a satisfying and tasty meal. Each element balances flavors and textures, making each bite a delight.

Step-by-Step Instructions
Cooking the Sushi Rice
1. Rinsing and boiling: Start by rinsing the sushi rice under cold water. You want to rinse until the water runs clear. This step helps remove excess starch. In a medium pot, combine 1 cup of rinsed rice with 1 1/4 cups of water. Bring it to a boil over medium heat.
2. Seasoning the rice: Once boiling, reduce the heat to low. Cover the pot and let it simmer for 15 minutes. After 15 minutes, turn off the heat but keep it covered for another 10 minutes. This allows the rice to finish cooking in steam.
3. Cooling process: For seasoning, mix 2 tablespoons of rice vinegar, 1 tablespoon of sugar, and 1/2 teaspoon of salt in a small bowl. Microwave this mixture for 15-20 seconds until combined. Fluff the rice gently with a fork, then fold in the vinegar mixture. Let the rice cool to room temperature.
Preparing the Spicy Tuna
1. Mixing tuna with mayonnaise and sriracha: In a separate bowl, take 8 ounces of diced sashimi-grade tuna. Add 2 tablespoons of mayonnaise and 1 tablespoon of sriracha. Stir until the tuna is fully coated in the spicy sauce.
2. Adjusting heat levels: If you want more heat, add a bit more sriracha. Taste your mixture to find the right balance for you. This is where you can make the dish your own!
Assembling the Sushi Bowls
1. Layering rice and toppings: Grab your serving bowls and start with a base of sushi rice. Top it with the spicy tuna mixture.
2. Garnishing the dish: Next, add sliced avocado, thinly sliced cucumber, and julienned carrot on top. For extra flavor, drizzle some sesame oil and soy sauce over the bowls. Finish by sprinkling sliced green onions, sesame seeds, and optional toasted seaweed strips for added texture.

Tips & Tricks
Perfecting Your Rice
To get the best sushi rice, start with rinsing it. Use a fine mesh strainer. Rinse the rice under cold water until the water runs clear. This step removes extra starch. It helps the rice not to clump.
Next, for cooking time, follow the ratio of 1 cup of rice to 1.25 cups of water. Bring the water to a boil, then lower the heat. Cover it and let it simmer for 15 minutes. After that, let it rest for 10 minutes off the heat. This allows the rice to absorb all the moisture.
Tuna Preparation Tips
When choosing tuna, look for sashimi-grade tuna. It should be bright red and smell fresh. A good piece of tuna is key for flavor and safety.
For mixing, use a bowl that allows space to stir. Combine diced tuna, mayonnaise, and sriracha. Mix gently to coat the tuna evenly. If you prefer less heat, add less sriracha. You can also mix in some chopped green onions for extra flavor.
Serving Suggestions
When serving, presentation matters. Start with a base of rice in a bowl. Add a generous scoop of spicy tuna on top. Arrange avocado, cucumber, and carrots around the tuna for color.
You can drizzle sesame oil and soy sauce over the top. Garnish with sesame seeds and sliced green onions. For added crunch, include toasted seaweed strips. This makes your dish look vibrant and appealing.
Pro Tips
- Rinse the Rice Well: Rinsing the sushi rice until the water runs clear is essential to remove excess starch, which helps achieve that perfect sticky texture.
- Use Quality Tuna: Always opt for sashimi-grade tuna for the best flavor and safety. Freshness is key when eating raw seafood.
- Customize Your Heat: Adjust the amount of sriracha in the spicy tuna mixture according to your spice tolerance. Start with a little and add more if desired.
- Fresh Toppings Matter: Use fresh vegetables for crunch and flavor. You can also experiment with different toppings like radishes or pickled ginger for variety.
Variations
Alternative Proteins
You can switch up the tuna for other tasty proteins. Salmon works great and adds a rich flavor. It has a nice, buttery texture that pairs well with the other ingredients. You can also use cooked shrimp or crab meat for a different twist. If you want a meat-free option, try marinated tofu or chickpeas. Both options soak up flavors and add protein.
Different Vegetable Combinations
Adding veggies brings crunch and color to your sushi bowl. You can use thinly sliced radishes for a peppery kick. Shredded purple cabbage adds a nice crunch and a pop of color. Carrots, cucumbers, and avocado are classic picks, but don't stop there! Consider seasonal veggies like bell peppers or zucchini. You can even throw in some pickled vegetables for a tangy twist.
Flavor Twists
Spicy mayo is a fantastic way to amp up flavor. You can mix the mayo with wasabi for an extra kick or add some lime juice for brightness. If you love a sweet touch, try mixing in some hoisin sauce. Drizzling sesame oil adds a nutty flavor too. Experiment with sauces to find your perfect balance!
Storage Info
Storing Leftovers
To keep your sushi rice fresh, store it in an airtight container. This keeps it from drying out. Sushi rice can last in the fridge for up to three days. If you have leftover spicy tuna mix, place it in a separate container. It should stay fresh for about two days.
Reheating Tips
When reheating sushi rice, use a microwave. Add a few drops of water to keep it moist. Heat in short bursts, stirring often. This way, the rice warms evenly. After heating, you can serve it with your favorite toppings again.
Freezing Options
You can freeze sushi rice but it may change texture. It’s best to use it fresh. If you must freeze it, let it cool first. Place it in a freezer-safe bag and remove air before sealing. For the tuna and veggies, yes, you can freeze them too. Just make sure they are in tight containers to avoid freezer burn.
