What Is Spicy Tuna?
Spicy tuna is a sushi-style mixture made with finely diced sushi-grade tuna, spicy mayo, sesame oil, and sriracha or chili sauce.
The best spicy tuna has a clean, fresh flavor, a creamy spicy sauce, and small pieces of tuna that hold their texture without becoming mushy.
While this recipe is commonly used for spicy tuna rolls and sushi appetizers, it can also be served poke-style over rice with fresh toppings and sauces.
Ways To Serve Spicy Tuna
Spicy ahi makes a light appetizer, easy lunch recipe, sushi roll filling, or quick seafood bowl. Serve the diced tuna over sushi rice for a filling meal, or spoon it onto crackers, cucumber slices, or crispy rice for a party-style appetizer.
You can also use this spicy tuna mixture as a filling for tuna rolls, hand rolls, crispy rice bites, or poke-style bowls. If you love spicy sushi rolls, try our Spicy Krab Roll.

Ingredients
This spicy tuna recipe uses a short list of simple ingredients. The most important part is starting with high-quality sushi-grade or sashimi-grade tuna.

- Sesame seeds, green onions, or other garnishes
Pro Tip: Keep the tuna very cold until right before serving. Cold tuna holds its texture better and gives spicy tuna the clean, restaurant-style texture you get at sushi bars.
How To Make Spicy Tuna
This recipe comes together in just 10 minutes with three simple steps: dice the tuna, fold in the sauce, and garnish before serving.

Expert Tips
- Place the tuna in the freezer for 10 minutes before cutting to make it easier to dice cleanly.
- Slice the tuna across the grain using one smooth swipe of a sharp knife instead of a back-and-forth sawing motion.
- Wipe and lightly wet the knife between cuts to help keep the fish from sticking.
- Cut the tuna into small, even pieces, about 1/8 to 1/4 inch thick, for the best texture.
- Mix the tuna gently instead of aggressively stirring it. Overmixing can break down the fish and create a mushy texture.
- Serve immediately after mixing for the freshest flavor and best texture.
- If serving for a party, prep the tuna in one bowl and the sauce in another. Toss them together right before serving.
- Plan on serving about 4 to 6 ounces of spicy tuna per person for bowls or appetizers.
- Use the freshest sushi-grade tuna you can find for the best flavor and texture. Look for fish labeled sushi-grade or sashimi-grade.
- Check your local Asian market or trusted fish market for sushi-grade ahi tuna. Frozen sushi-grade tuna can also work if fresh tuna is not available.
- Raw tuna is best enjoyed the same day it is purchased. The flavor becomes stronger and fishier the longer it sits.
Shortcut Tip: While sushi-grade ahi tuna delivers the best restaurant-style flavor and texture, you can use drained canned tuna for a quick budget-friendly version. The texture will be softer and less silky, but it still works well for spicy tuna bowls, wraps, and sushi-inspired appetizers.

Raw Fish
Always purchase sushi-grade or sashimi-grade tuna from a trusted fish market or grocery store with high seafood turnover. If you have questions about safely consuming raw fish, consult your fishmonger or healthcare provider.
Raw fish is not recommended for pregnant women, elderly individuals, immunocompromised individuals, or anyone advised to avoid raw seafood.
