These Cucumber Sushi Bites are a fun and fresh twist on sushi! With crunchy cucumber, flavorful fillings, and a touch of soy sauce, they’re perfect for a light snack or party treat.
Making these bites is super easy! I love how they look fancy but come together in no time. Plus, you can fill them with whatever you like—creativity is key here!
Key Ingredients & Substitutions
Cucumber: I recommend using English cucumber for its crispness and minimal seeds. If you can’t find it, Persian cucumbers are a great alternate with similar qualities.
Sushi-grade Salmon or Tuna: Freshness is key here! If you’re looking for a seafood alternative, diced avocado can provide a rich flavor and creamy texture, making it vegetarian-friendly.
Japanese Mayonnaise: Kewpie mayo adds a delightful umami flavor. However, regular mayonnaise works fine if you’re in a pinch. You might consider adding a bit of rice vinegar and sugar to replicate Kewpie’s taste.
Sriracha: This adds a nice kick. If you prefer milder flavors, a bit of sweet chili sauce can substitute well, offering sweetness along with a hint of heat.
Sesame Oil: This oil gives a nutty aroma. If you need a substitute, try using olive oil mixed with a few sesame seeds for flavor.
How Can I Make the Cucumber Cups?
Creating the perfect cucumber cups is easier than you think! Here’s how to do it smoothly:
- Start by cutting the cucumber into even rounds, right about ½ to ¾ inch thick. This size allows for good filling without being too bulky.
- Use a small spoon or melon baller to gently scoop out the center. Be cautious not to go all the way through to the bottom; you’re making a little cup.
- Take your time with this; a steady hand will help create a clean look. If you’re not comfortable with scooping, just leave the center as is for a more rustic approach!
These tips will ensure your cucumber bites look great and are ready to fill with delicious flavors!

Ingredients You’ll Need:
For the Cucumber Cups:
- 1 large English cucumber
For the Filling:
- 6 oz fresh sushi-grade salmon or tuna, finely diced
- 2 tablespoons mayonnaise (preferably Japanese mayo like Kewpie)
- 1 teaspoon Sriracha (or to taste)
- 1 teaspoon soy sauce
- 1 teaspoon sesame oil
- 2 green onions, finely chopped
For Garnish:
- 1 tablespoon toasted sesame seeds (mix of black and white)
- Optional: 1 teaspoon yuzu juice or lemon juice for brightness

How Much Time Will You Need?
This charming dish takes about 15 minutes to prepare. You’ll spend a few minutes chopping and mixing the filling, plus some time scooping the cucumber. You can serve these right away, so they’re perfect for a quick appetizer or snack!
Step-by-Step Instructions:
1. Prepare the Cucumber:
Wash the cucumber thoroughly to remove any dirt or wax. Cut it into approximately ½ to ¾ inch thick rounds. Using a small spoon or a melon baller, gently scoop out a small well in the center of each cucumber slice without piercing the bottom. This will create fun little cups for your filling!
2. Make the Filling:
In a medium bowl, mix together the diced sushi-grade salmon or tuna with mayonnaise, Sriracha, soy sauce, sesame oil, and yuzu or lemon juice if you’re using it. Stir until everything is well combined and creamy. This mixture is what will make your bites delicious!
3. Fill the Cucumber Cups:
Spoon a dollop of the fish mixture into the center of each cucumber cup, mounding it slightly on top. Don’t be shy; make them look tempting!
4. Add Toppings:
Sprinkle each filled cucumber bite generously with chopped green onions and toasted sesame seeds. If you like a little extra kick, sprinkle some crushed red pepper flakes or furikake seasoning on top as well.
5. Serve and Enjoy:
Arrange the cucumber sushi bites on a serving platter, and serve immediately. They are best enjoyed fresh, paired with some extra soy sauce or wasabi on the side. Enjoy your delightful and refreshing snack!
These fresh cucumber sushi bites are crunchy, creamy, and full of umami flavor—perfect for a light appetizer or a fun party treat!
Can I Use Other Fillings Besides Salmon or Tuna?
Absolutely! You can use diced avocado for a vegetarian option, or even cooked shrimp, crab, or tofu for variety. Just ensure whatever you choose is fresh and complements the flavors!
How to Store Leftovers?
If you have leftovers, store the cucumber cups and filling separately in airtight containers in the fridge. The cucumber will become soggy over time, so it’s best to fill them just before serving. Enjoy within a day for the best taste and texture!
Can I Make These Ahead of Time?
While the filling can be made a few hours in advance and stored in the fridge, it’s best to assemble the cucumber bites just before serving to keep them crunchy and fresh!
What’s the Best Way to Cut the Cucumber?
Make sure to cut the cucumber into even, thick rounds (about ½ to ¾ inch) for sturdy cups. Use a sharp knife and a steady hand to ensure clean edges, and take care not to pierce the bottom when scooping out the center!
