Crispy Rice Spicy Tuna Ingredients
For the Sushi Rice
• Sushi Rice – Essential for stickiness and shape retention; use short-grain sushi rice for the best texture.
• Water – Provides hydration for cooking the rice; ensure precise measurements for perfect consistency.
• Rice Vinegar – Used for seasoning the sushi rice; opt for unseasoned rice vinegar to avoid overpowering flavors.
• Sugar – Adds a touch of sweetness to balance the vinegar; white granulated sugar is recommended.
• Salt – Enhances flavor; adjust as necessary based on personal taste.
For Frying the Rice
• Vegetable Oil (Sunflower/Pegnut Oil) – Essential for achieving a crispy exterior; heat oil to 350°F (180°C) for frying.
For the Spicy Tuna Mixture
• Sushi-Grade Ahi Tuna – The main protein element with a delicate flavor; alternative: use cured smoked salmon or well-drained canned tuna.
• Japanese Kewpie Mayonnaise – Provides an authentic creamy taste; regular mayo can be substituted, but flavor may differ.
• Sriracha Sauce – Adds a mild heat; adjust the quantity based on your desired spice level.
• Soy Sauce – Complements the spicy mayo and enhances umami flavor; use it to add depth to the mixture.
• Lime Juice – Brightens flavors; fresh-squeezed juice is best, but lemon juice can be a suitable substitute.
For the Toppings
• Avocado – Adds creaminess; select a ripe but firm avocado for easy slicing.
• Jalapeños – An optional topping that adds a spicy kick; remember to remove seeds if you prefer less heat.
• Sesame Seeds – Optional garnish mainly for decorative purposes.

Step‑by‑Step Instructions for Crispy Rice Spicy Tuna
Step 1: Prepare Sushi Rice
Rinse 1 cup of sushi rice under cold water until the water runs clear, which may take about 3-4 rinses. In a medium saucepan, combine the rinsed rice with 1 ¼ cups of water and bring to a boil over medium-high heat. Once boiling, reduce the heat to low, cover, and let it simmer for 18-20 minutes until the water is absorbed. Remove from heat and allow the rice to rest for 10 minutes with the lid on.
Step 2: Make Sushi Rice Seasoning
In a small saucepan, combine 2 tablespoons of rice vinegar, 1 tablespoon of sugar, and ½ teaspoon of salt. Heat over low flame, stirring frequently until the sugar dissolves. This seasoning will enhance the sushi rice’s flavor. Once ready, remove from heat and set aside until the rice has cooled slightly.
Step 3: Season & Shape Rice
Gently mix the sushi rice with the prepared seasoning, being careful not to mash the grains. Transfer the seasoned rice into an 8”x8” square pan lined with plastic wrap, pressing down firmly to create an even layer about 1 inch thick. Cover with additional plastic wrap and chill in the refrigerator for at least 30 minutes to firm up and hold its shape, crucial for your crispy rice spicy tuna.
Step 4: Cut the Rice
Once chilled, remove the rice from the pan using the plastic wrap for ease. Place it on a cutting board and, using a sharp knife, cut the rice into rectangles measuring approximately 2 inches by 1 inch to yield around 15 pieces. Cut carefully to maintain the integrity of the shapes, as these will be fried for your crispy rice spicy tuna.
Step 5: Fry the Rice
In a large, deep skillet, heat 1 inch of vegetable oil to 350°F (180°C) over medium-high heat. Carefully add the rice rectangles in batches, frying for about 2-3 minutes per side, or until they’re golden brown and crispy. Use a slotted spatula to remove them and transfer to a paper towel-lined plate to drain any excess oil. You now have the perfect crispy base for your spicy tuna topping!
Step 6: Prepare Spicy Tuna
In a mixing bowl, combine 4 ounces of chopped sushi-grade Ahi tuna with 2 tablespoons of Japanese Kewpie mayonnaise, 1 tablespoon of Sriracha sauce, 1 teaspoon of soy sauce, and the juice of half a lime. Mix gently until the tuna is well-coated, and adjust the spice level to your preference. This creamy, zesty blend is the star of your crispy rice spicy tuna dish!
Step 7: Slice Toppings
While the crispy rice cools, slice one ripe avocado into thin wedges and, if using, dice 1-2 jalapeños. The avocado will provide a creamy contrast to the spicy tuna, and jalapeños will add a delightful kick if you choose to include them. Arrange the toppings so they are ready for assembly.
Step 8: Assemble
On each piece of crispy rice, place a slice of avocado, followed by a generous spoonful of the spicy tuna mixture. If desired, finish with diced jalapeño and a sprinkle of sesame seeds for garnish. Serve your crispy rice spicy tuna immediately, allowing your guests to experience the vibrant flavors and textures right away!

Storage Tips for Crispy Rice Spicy Tuna
Fridge: Store leftover crispy rice and spicy tuna separately in airtight containers. The rice is best eaten within 1 day, while the spicy tuna can last up to 2 days in the fridge.
Freezer: For longer storage, freeze plain crispy rice squares in a single layer on a baking sheet, then transfer to a freezer-safe bag after they’re frozen. They’ll retain quality for up to 2 months.
Reheating: To reheat crispy rice, bake in a preheated oven at 375°F (190°C) for about 10 minutes until heated through to regain some of its crunch. Avoid microwaving, as it can make the rice soggy.
Assembling: It’s best to assemble the crispy rice spicy tuna fresh. If you plan to serve later, keep all components separate and combine before serving to enjoy optimal freshness and texture.

Crispy Rice Spicy Tuna Recipe FAQs
What kind of rice should I use for the crispy rice spicy tuna?
You should use short-grain sushi rice for the best texture. This type of rice has the perfect level of stickiness, which is essential for shaping the rice squares. When rinsing, make sure the water runs clear—you’ll typically need to rinse it 3 to 4 times to remove excess starch.
How should I store leftover crispy rice and spicy tuna?
To maintain the quality, store leftover crispy rice and spicy tuna separately in airtight containers. The crispy rice is best consumed within 1 day for optimal texture, while the spicy tuna can last up to 2 days in the fridge. Make sure it’s sealed well to prevent it from drying out.
Can I freeze crispy rice spicy tuna?
Absolutely! For freezing, lay the plain crispy rice squares in a single layer on a baking sheet and freeze until solid, then transfer them to a freezer-safe bag. They’ll keep their quality for up to 2 months. However, it’s important to note that the filled crispy rice should be assembled fresh for the best taste and texture.
What do I do if my crispy rice turns out soggy?
If your crispy rice isn’t as crispy as you’d like, check the oil temperature. It should be at 350°F (180°C) when frying; using a kitchen thermometer is key! If they’re soggy, consider frying them a bit longer, but be cautious not to burn them. Also, make sure to rinse thoroughly before cooking to minimize starch.
Are there any dietary considerations for the ingredients?
Yes! If you’re serving this dish to someone with seafood allergies, I recommend using canned tuna or smoked salmon as substitutes. For those with specific dietary preferences, you can skip the spicy mayo or use a plant-based alternative. Always keep in mind any specific allergies when preparing for guests—it’s always better to double-check!
Can I prepare the rice in advance?
Definitely! You can prepare the sushi rice a day ahead. Just make sure to chill it in the refrigerator for at least 30 minutes after seasoning to ensure it holds its shape when you cut and fry it the next day. This makes for a convenient prep step if you’re hosting!
