📖 Recipe

This is my Japanese-inspired take on a deconstructed spicy tuna sushi roll without the hassle of filling and rolling sushi! The tender spicy tuna contrasts deliciously with the crunchy cucumbers and the seasoned rice and roasted seaweed complement each other perfectly.

I eat this once a week as it's so satisfying, easy, cheap, and requires little preparation time or ingredients. It's a super simple Asian rice recipe made with pantry ingredients, like canned tuna and roasted seaweed. It's also a great way to add seafood to your diet.

Why This Recipe Works

I tested this with different types of rice and recommend short-grain white rice for its slightly sticky texture and best overall flavour.
Canned tuna in oil works better than tuna in water, giving a richer, more tender result.
Many tuna rice bowls are overloaded with toppings, but I've found this dish works best when kept simple - less really is more.

Ingredients & Substitutes

Please scroll to the recipe card below for exact measurements.

Canned Tuna: Use tuna packed in oil for a more tender texture (I recommend Dongwon, commonly found at Korean grocers such as H-Mart). Substitution: Tuna packed in water.
Cooked short-grain rice (such as Calrose or sushi rice): Short-grain rice gives a slightly sticky texture. Substitutions: medium- or long-grain white rice. Avoid brown rice unless you're comfortable with its firmer texture.
Toasted Sesame Oil: Adds a nutty aroma [I recommend Kadoya or Maruhon]. Avoid substituting with untoasted sesame oil as it doesn't taste the same.
Regular Soy Sauce: Any all-purpose brand works [I recommend Kikkoman or Lee Kum Kee]. Low-sodium or light soy sauce also works.
Roasted Seaweed Flakes (Gimjaban): Seasoned Korean flakes that add a nutty and sweet flavor [I recommend Paik Cook or Bibigo]. Substitution: Crushed nori with a drop of sesame oil and salt.
Sriracha: A garlicky red chili sauce for heat [I recommend Huy Fong]. For a fruitier alternative, use Sky Valley or Shark brands.
Japanese Mayo: A rich, tangy mayo made with egg yolks and rice vinegar [I recommend Kewpie, look for a clear squeeze bottle with a red cap]. Substitution: Mix Hellmann's mayo with a pinch of sugar and rice vinegar.
Cucumbers: For a refreshing crunch. Substitution: Avocado.
Nori: Dry roasted seaweed sheets used for sushi to serve with rice bowl.

Note: Asian ingredients are typically available at most Asian grocery stores, or you can check online.

Instructions

Below are step-by-step instructions on how to make spicy tuna rice bowl:

Spread the hot cooked rice into a large serving bowl. If using leftover rice, cover and microwave for 2-3 minutes, or until heated through.
Season the rice with soy sauce and sesame oil, then mix well with a rice paddle or spoon. Cover to keep warm.
Strain the canned tuna through a fine sieve, using a fork to press out any excess liquid. Spoon half (or more, if desired) over the rice.
Top with thinly sliced cucumbers.
Drizzle generously with sriracha and Japanese mayo, to taste.
Finish with roasted seaweed flakes. Mix and enjoy as is, or scoop spoonfuls onto nori squares to eat.

Expert Tips

Use canned tuna in oil for the best texture; tuna in water works too but tends to be drier.
Strain the tuna well using a fine sieve to remove excess liquid and prevent a soggy rice bowl.
Use freshly cooked rice whenever possible, as it has better moisture and flavour than leftover rice.
If using leftover rice, avoid rice older than 3 days and microwave it covered to help retain moisture.
Keep toppings minimal so the flavour of the tuna, rice, and seasoning can shine.

Variations

Gluten-free version: Swap the soy sauce with tamari sauce, coconut aminos, or gluten-free soy sauce.
Salmon version: Replace the canned tuna with cooked salmon.

Topping Ideas

Feel free to add 1-2 of the toppings below, but avoid overloading the bowl:

Cooked eggs: sunny side up, over-easy, scrambled, or soft-boiled.
Kimchi
Furikake seasoning
Avocado
Vegetables: sautéed carrots or spinach, boiled edamame, or steamed broccoli

Pairing Suggestions

This spicy tuna rice bowl pairs well with:

Starters: Miso Soup, Korokke, or Crab Corn Salad.
Seafood Dishes: Shrimp Tempura
Protein Dishes: Chicken Katsu or Enoki Beef Rolls.
Noodle Dishes: Yaki Udon or Creamy Mushroom Udon.

Storage & Reheating

Leftover spicy tuna rice bowls will keep for up to 2-3 days when stored in an airtight container in the fridge. Store the components separately to maintain the best texture. To serve, reheat in the microwave or on the stovetop until warmed through.
Freezer-friendly? Spicy tuna rice bowl is not ideal for freezing as the rice will turn hard.

FAQ

Can I make spicy tuna rice bowl in advance?

Spicy tuna rice bowl can be made up to 2-3 days in advance. For best results, store the components separately in airtight containers in the fridge. To serve, reheat the rice in the microwave or on the stovetop until heated through.

How can I make this spicy tuna rice bowl less spicy?

To make this spicy tuna rice bowl mild or non-spicy, reduce the sriracha or omit it entirely. For added flavour, replace it with teriyaki sauce or eel sauce.

What is the best way to cook rice?

For perfectly steamed rice, I prefer using a rice cooker (the exact model is linked in the Equipment section of the recipe card) rather than the stovetop.
To prepare, rinse the rice under cold running water several times until the water runs clear. Drain well, then transfer to the rice cooker. Add the appropriate amount of cold water and cook according to your rice cooker's settings or instructions.
