One of my go-to easy meals to eat is my Japanese Spicy Tuna Cucumber Roll because it’s low-carb. keto-friendly and is very similar to make. Not only are there only 4 ingredients to make this recipe, but you can make this dish relatively quickly. I love the fact that this savory dish has such a delicious cooling crunch from the cucumber, yet has a warm spicy flavor from the sriracha sauce. When it comes to our tastebuds, it’s a fun adventure when your mouth can taste different textures and flavors.

Just remember, you’ll want to use regular thick 6″- 8″ cucumber to make this Japanese Spicy Tuna Cucumber Roll. The reason is that English cucumbers also known as house cucumbers are long and very narrow. Persian and Japanese cucumbers are relatively short and thin. Because those cucumbers have slimmer in diameter, it will be harder to produce longer ribbon-like pieces to wrap your sushi with. And yes, we’re still talking about this vegetable, so don’t be took cheeky thinking otherwise.

In addition to this Japanese Spicy Tuna Cucumber Roll recipe, you may want to also try making my other refreshing Japanese-inspired sushi rolls like my Japanese Yellowtail and Cilantro Cucumber Roll and Japanese Salmon and Cream Cheese Philly Cucumber Roll. And if you love cucumbers, you will want to try my Easy Chinese Cucumber Salad Side Dish. It’s refreshing and light with a slight kick of heat if you include the chili flakes.

Japanese Spicy Tuna Cucumber Roll Recipe

Yield: 2
Prep Time: 20 minutes

This Japanese Spicy Tuna Cucumber Roll will satisfy your craving for sushi and it's low carb.


  • 10 oz of raw diced sushi grade bluefin tuna
  • 3 cups of ribbon sliced house cucumbers (2 or 3 cucumbers)
  • 2 tsp of sriracha sauce
  • 2 tsp of soy sauce


    1. Peel and remove the skin of the cucumber.
    2. To make the sushi roll wraps, peel the cucumber vertically from one end to the other to create thin ribbon-like cucumber slices. Repeat the process until you start to see the cucumber seeds, then stop because cucumber slices will break apart. So then peel from the opposite side of the cucumber.
    3. To make the spicy tuna, dice the tuna and mix in 2 tsp of sriracha sauce.
    4. Scoop a small spoonful of the spicy tuna on one end of the cucumber ribbon slice, roll up, and repeat until you’ve created about 10-15 spicy tuna cucumber rolls. Serve with soy sauce.
