If you’re in the mood for something light, refreshing, and fun to make, I highly recommend trying these Cucumber Sushi Rolls! They’re a perfect combination of creamy mashed potatoes, flavorful tuna salad, and crunchy cucumber, making them a unique twist on traditional sushi.
Why This Cucumber Sushi Roll is Special
I absolutely love tuna in all its forms—whether it’s in a classic tuna sandwich, a refreshing tuna cucumber salad, or a tuna potato salad.
There’s just something about the combination of tuna and cucumber that feels like a match made in heaven!
After I make my tuna cucumber salad, I like to get a little creative with how I use it in different dishes.
While I’m a big fan of traditional sushi with rice, I wanted to try something different with this recipe.
This Cucumber Sushi Roll is a fun twist because it skips the rice entirely, making it much lighter and fresh. It’s a great option for anyone looking for a healthier sushi alternative or just something new to try!
For this recipe, I prefer to use large, straight cucumbers because they’re easier to slice evenly and they create beautiful, long strips for rolling.
I use a vegetable peeler to cut the cucumbers into thin, even slices.
The best part is that you can get as creative as you like with the fillings! I’ve chosen to add mashed potatoes to my roll because they’re soft and creamy, but if you’re looking for a quicker version or prefer not to cook, feel free to skip that step entirely.
Tips for Making the Perfect Cucumber Sushi Rolls
- Choose the Right Cucumbers: Use large, straight cucumbers for easier slicing and rolling.
- Slice Thin and Even: A vegetable peeler works best for creating thin, uniform cucumber strips.
- Get Creative with Fillings: Besides tuna and potatoes, you can add avocado, carrots, bell peppers, or even quinoa for extra flavor and texture.
- Season to Taste: Adjust the seasoning in the tuna salad to your preference. Add a squeeze of lemon juice or a dash of chili flakes for a zesty kick.
Ingredients
- 2-3 potatoes (about 300g)
- 1 cucumber
- 1 can of tuna (80g)
- Steamed corn kernels (50g)
- 1 tsp crushed black pepper
- 1/2 tsp salt
- 1 tbsp mayonnaise (or salad dressing as a substitute)
- A little chopped parsley (optional, for decoration)
Instructions
Prepare the Potatoes: Wash and peel the potatoes, then cut them into even small pieces. This will ensure they cook at the same time. Steam the potato pieces over high heat for 15-20 minutes, or until they’re soft and can be easily pierced with chopsticks. Once the potatoes are done, take them out of the steamer and mash them until smooth using a spoon or rolling pin. Stir in 1/4 tsp salt and 1/2 tsp crushed black pepper. Set the mashed potatoes aside.
Prepare the Cucumber: Wash the cucumber and use a vegetable peeler to slice it into long, even strips. Try to keep the slices intact and consistent in width. Once sliced, roll up each cucumber strip and set them aside.

Prepare the Tuna: In a bowl, add 50g of cooked corn kernels. Open the tuna can and drain out most of the olive oil. You can place the tuna in a sieve to let the excess oil drip out. Once drained, add the tuna to the bowl with the corn. Add 1/2 tsp crushed black pepper, 1/4 tsp salt, and 1 tbsp mayonnaise. Mix well until the tuna absorbs all the flavors.
Assemble the Sushi: Form the potato mixture into small balls. Carefully place each ball inside a cucumber roll and press them down to flatten. Top with the tuna salad mixture and sprinkle with chopped parsley for a little extra flavor and color.

Frequently Asked Questions
Can I make this ahead of time?
Yes! You can prepare the mashed potatoes and tuna salad in advance and refrigerate them. Just assemble the cucumber rolls when you’re ready to serve.
What other fillings can I use?
If you’re not a fan of tuna, you can substitute it with other fillings such as chicken salad, crab meat, or even a vegetarian option like avocado and pickled carrots.
Can I use store-bought mayonnaise?
Absolutely! If you’re in a pinch, store-bought mayonnaise works just fine.
