Sushi is one of my favorite meals and I could eat this every day if I could. You’ll want to make your own sushi at home after you try this recipe. Tender pieces of tuna are coated in a spicy mixture that will have you craving more instantly after the first bite.

If you want to make your own sushi at home, try my homemade California roll! This roll pairs so perfectly together and makes the best meal. You could even add this spicy tuna on top of the roll if you want to get really creative ;).

I especially love tuna when it comes to sushi (I’m also obsessed with my Homemade Tuna Poke).  It’s just as easy to make and it can also be served on top of sliced cucumbers if you wanted an alternative that wasn’t spicy.

INGREDIENTS

Tuna: you can use any type of tuna as long as it’s sashimi grade. Make sure to ask your local fish market or fish department at the grocery store if you are not sure. 

Mayonnaise: to make the spicy mayo. You can also use plain nonfat Greek yogurt if you wanted a healthy alternative.

Sriracha sauce: the key ingredient that makes this tuna spicy.

Soy sauce: reduced-sodium is always preferred so you can control the salt intake. 

Sesame oil and chili oil: both can be found near the other Asain products at the grocery store. A little bit goes a long way. 

Green onions: use both green and white parts. Make sure they are thinly sliced.

Sesame seeds: you can use black seeds, white seeds, or both. The white sesame seeds are usually easier to find. 

Cucumber slices: a low-carb alternative. You can also top the tuna on lettuce, cauliflower rice, white rice, or add it to seaweed and rice to make a spicy tuna roll. 

HOW TO MAKE SPICY TUNA

RECIPE VARIATIONS

Add the spicy mayonnaise on the side. If you want your spicy tuna to be mild, or not too spicy, omit the spicy mayonnaise and serve it on the side. I do this when I make sushi bowls (see photo below). This will allow you to control the spiciness. 

If you prefer cooked fish, you could make this with cooked shrimp, canned or cooked tuna, canned or cooked salmon, cod, or crab. 

Add this spicy tuna to avocado halves to make stuffed avocados. 

Make the tuna spicer or milder by adding more or less of the sriracha sauce and sriracha mayonnaise. You can control the heat in this recipe. 

You can add this tuna mixture to seaweed wraps, lettuce wraps, salads, or enjoy it just as it is!

HOW TO MAKE SPICY CANNED TUNA

Not a fan of raw tuna? That’s ok! You can still make this delicious recipe by using canned tuna fish. To alter the recipe replace the raw tuna with 1 pound of canned tuna. Make sure to drain as much liquid as you can before. The other ingredients remain the same. 

SUSHI BOWL

Another way to enjoy this spicy is tuna is by making a Spicy Tuna Bowl! If you love sushi and don’t want to make or know how to make sushi rolls, a Sushi Bowl is the way to go. 

Simply add either white rice or brown rice to a bowl and top with spicy tuna. Add sliced cucumbers, avocados, and whatever else you love. Other topping ideas are crab meat, shrimp, shredded carrots, pickled ginger, edamame, microgreens, lettuce, seaweed, and cubed mango.

LEFTOVERS

Store any leftovers in an airtight container for up to 1 day. I don’t like keeping this around for too long because raw fish tends to go bad quicker than cooked fish so it’s better to be on the safe side.
