Cucumber Sushi Rolls offer a light, refreshing, and nutritious twist on classic sushi. This version replaces rice and nori with thin cucumber slices, creating a crisp, low-carb option that’s ideal for warm weather or when you want something fresh and satisfying. The recipe is quick to assemble and highlights clean flavors—seared ahi tuna tossed in a creamy spicy mayo, bright pickled carrots, and creamy avocado all wrapped in delicate cucumber.

The Best Cucumber Sushi Rolls
I love sushi, and while traditional rolls with rice are delicious, these cucumber sushi rolls are a fantastic low-carb alternative that still delivers great texture and flavor. Cucumber’s high water content makes these rolls particularly refreshing, so they’re perfect for hot days or when you want a lighter meal. They come together faster than conventional sushi since you skip cooking and seasoning sushi rice.
These rolls are great as an appetizer, light lunch, or party snack. Minimal ingredients and simple equipment—a sharp knife, a mandoline or peeler, and a sushi mat—are all you need to make attractive, satisfying rolls at home.

Kelley’s Tips
Tips Before You Get Started
- Choose the Right Cucumber: Pick large, firm cucumbers with smooth skin. English or seedless varieties work best because they have thinner skin and fewer seeds, which makes them easier to slice thinly and roll.
- Slice Evenly: Use a mandoline or a vegetable peeler to create uniform, thin strips. Even slices help the roll hold together and give a clean presentation.
- Use a Sharp Knife: A very sharp knife gives cleaner cuts when slicing the rolled cucumber. Wipe the blade between cuts to keep pieces neat and intact.
Ingredients Needed
- Ahi Tuna: Use fresh ahi tuna steaks and sear them quickly for a golden crust while keeping the center tender and pink.
- Mayonnaise: The base for the spicy mayo that dresses the seared tuna. Use your preferred mayonnaise for best results.
- Sesame Oil: Adds a pleasant nutty aroma to the spicy mayo and ties the ingredients together.
- Sriracha: Provides heat—adjust the amount to taste.
- Cucumber: Thinly sliced to replace the rice and seaweed, creating a crisp, low-carb wrapper.
- Pickled Carrots: Add tang and crunch; shredded raw carrots are an easy substitute if you prefer.
- Avocado: Sliced avocado adds creaminess and balances the spicy tuna.
- Soy Sauce: For dipping when serving.
How to Make Cucumber Sushi Rolls
- Prep the Cucumber: Wash and trim the ends. Using a mandoline or vegetable peeler, shave long thin strips from the cucumber. Overlap the strips slightly on a sushi mat lined with plastic wrap to form a long, even sheet of cucumber.
- Season the Tuna: Pat tuna fillets dry and season both sides with salt and pepper.
- Cook the Tuna: Heat a skillet over high heat with a little oil. When the pan is hot and seasoning begins to smoke lightly, sear the tuna for about 2 minutes per side until a golden crust forms. The center should remain pink. Transfer to a cutting board and let it rest a few minutes, then dice into bite-sized pieces.
- Make the Spicy Mayo: In a small bowl, mix mayonnaise, sesame oil, and sriracha until smooth. Taste and adjust the sriracha for your preferred heat level.
- Dress the Tuna: Toss the diced tuna with the spicy mayo until evenly coated.
- Assemble: Arrange spicy tuna, avocado slices, and pickled carrots along one edge of the cucumber sheet. Use the bamboo mat to roll the cucumber tightly, forming a compact roll.
- Cut & Serve: Transfer the roll to a cutting board and slice into eight pieces with a sharp knife. Serve with soy sauce for dipping and enjoy immediately for the best texture.







Frequently Asked Questions
What can I serve with cucumber tuna sushi rolls?
These rolls are excellent on their own, but you can pair them with light soups, steamed edamame, a simple cucumber avocado salad, or a small bowl of fried rice to create a fuller meal. A side of pickled vegetables also complements the flavors well.
Can I add other ingredients to the filling?
Absolutely. Avocado and pickled or shredded carrots are classics, but thinly sliced bell pepper, green onion, pickled ginger, cream cheese, or cubed tofu can all be great additions. This recipe is versatile and works well for using cooked seafood or leftover grilled fish.
