Spicy Tuna Crispy Rice Ingredients

For the Rice
• Sushi Rice – Essential for structure and texture; a short-grain rice that is sticky when cooked. Use rinsed sushi rice for best results.
• Water – Cooks the rice; the key to achieving the right rice consistency.
• Salt – Adds flavor to the rice.
• Rice Vinegar – Provides a tangy flavor that complements the salty texture of sushi rice.
• Granulated Sugar – Balances the acidity from the rice vinegar; can be adjusted to taste.
• Sesame Oil – Adds a nutty flavor to the rice.

For the Spicy Tuna
• Ahi Tuna (sushi grade) – The main protein; ensure it is fresh and vibrant in color. Can substitute with seared ahi if raw fish is a concern.
• Japanese Kewpie Mayonnaise – Creamy texture and rich flavor unique to this dish; regular mayonnaise can be used but will alter the taste.
• Sriracha – Adds heat to the tuna mix; adjust to taste for spiciness.
• Soy Sauce – Enhances the umami flavor of the tuna; use a sushi-specific variety for best results.
• Lime Juice – Freshens the flavor profile of the spicy tuna; adjust to taste.

For Toppings and Garnish
• Avocado – A creamy topping that contrasts the crispiness of the rice.
• Toasted Sesame Seeds – Garnish; enhances flavor and adds texture.
• Chives or Scallions – Fresh note; can substitute with green onions.
• Jalapeño or Serrano Pepper – Provides extra spiciness; can be omitted for a milder taste.

How to Make Spicy Tuna Crispy Rice

Prepare the Rice: Rinse the sushi rice under cold water until the water runs clear. Cook with water and a pinch of salt to achieve the perfect sticky consistency that binds the rice together.
Flavor the Rice: In a separate bowl, whisk together rice vinegar, sugar, and sesame oil. Gently fold this mix into the cooked rice, ensuring it’s evenly distributed for that delicious tangy flavor.
Shape and Chill: Press the flavored rice into a square baking tray, smoothing it out to create an even layer. Chill in the fridge for at least an hour, allowing it to firm up for easier cutting.
Cut Rice: Once chilled, take the set rice out of the tray and cut it into bite-sized rectangles. Each piece should be just the right size for snacking!
Fry Rice: Heat a bit of oil in a skillet over medium heat. Carefully add the rice rectangles and fry until golden brown and crispy on both sides, about 5-6 minutes total.
Prepare Spicy Tuna: In a mixing bowl, combine the chopped sushi-grade tuna, Kewpie mayonnaise, Sriracha, soy sauce, sesame oil, and lime juice. Mix until well combined and creamy.
Assemble: Place a slice of avocado on each crispy rice piece, then top with a generous dollop of the spicy tuna mixture. Finish with a sprinkle of toasted sesame seeds, chopped chives, and jalapeño slices for that extra flair.

Optional: Garnish with fresh cilantro for an added burst of flavor.

Expert Tips for Spicy Tuna Crispy Rice

Choose Fresh Tuna: Always opt for sushi-grade tuna to ensure maximum freshness and minimize health risks. It’s essential for the quality of your spicy tuna mix.
Oil Temperature: Use a thermometer to monitor the oil temperature while frying. Too hot, and the rice will burn; not hot enough, and the squares won’t crisp up.
Avoid Soggy Rice: Once cooked, let the rice cool completely before shaping and chilling. This helps the rice hold its structure and creates that perfect crispy exterior.
Customize Spice Levels: Adjust the amount of Sriracha to suit your spice preference. Start with less, then add more for that signature kick in your spicy tuna crispy rice.
Keep Toppings Fresh: If making in advance, store the crispy rice squares and spicy tuna mixture separately to prevent sogginess before serving.

Storage Tips for Spicy Tuna Crispy Rice

Fridge: Store leftover spicy tuna crispy rice in an airtight container for up to 2 days. To retain crispness, it’s best to keep the crispy rice squares and spicy tuna mixture separate until serving.

Freezer: For longer storage, freeze the plain fried rice squares for up to 2 months. Wrap them tightly in plastic wrap and store in an airtight freezer bag to prevent freezer burn.

Reheating: To reheat frozen rice squares, bake in an oven at 375°F (190°C) for about 10-15 minutes or until heated through and crisped. Avoid microwaving as it can make them soggy.

Prepare Ahead: The spicy tuna mixture can also be made a day in advance and stored in the refrigerator to save time on serving day. Just mix well before topping the crispy rice.

Spicy Tuna Crispy Rice Squares Recipe FAQs

How do I choose the right sushi rice?
Absolutely! Look for short-grain sushi rice, which is essential for achieving that perfect sticky texture. Rinse it under cold water until the water runs clear—this eliminates excess starch and ensures fluffy rice. I recommend using high-quality brands specific for sushi to elevate the flavor!

What’s the best way to store leftovers?
Very! To store leftover spicy tuna crispy rice, place it in an airtight container in the fridge for up to 2 days. I suggest keeping the crispy rice squares separate from the tuna mixture to maintain their crunch. If you’re in a hurry, serve them fresh and enjoy the divine textures and flavors right away!

Can I freeze the crispy rice squares?
Of course! For longer storage, you can freeze the plain fried rice squares for up to 2 months. Wrap each square tightly in plastic wrap and place them in an airtight freezer bag. When you’re ready to enjoy them, simply bake them in the oven at 375°F (190°C) for about 10-15 minutes until they’re heated through and crispy again. This method avoids the sogginess that microwaving can cause.

What if my rice isn’t crisping up properly?
If your rice isn’t crisping up, check the oil temperature to ensure it’s hot enough—around 350°F (175°C) is ideal. Too low, and the rice will absorb oil instead of frying crisp. Fry them for about 5-6 minutes, turning to achieve golden brown on both sides. For best results, don’t overcrowd the skillet—work in batches if necessary for that delightful crunch!

Is there a way to make this dish vegan-friendly?
Absolutely! To make your spicy tuna crispy rice squares vegan, replace the ahi tuna with a mix of diced avocado, cucumber, and a vegan mayonnaise alternative, like chickpea mayo or cashew cream. Add some sriracha and lime juice to mimic that zesty, spicy flavor, and you’ll have a delicious and satisfying vegan treat!

What should I do if I have allergies?
Great question! For common allergies, I recommend ensuring that you use fresh, allergy-friendly ingredients. If you’re concerned about seafood, simply swap the tuna for grilled vegetables or tofu, and keep an eye on any sauces like soy sauce for gluten or nut allergens. Always read product labels to be sure!
