Spicy Tuna on Cucumber Rounds
This Spicy Tuna on Cucumber Rounds recipe offers a refreshing, low-carb take on a classic spicy tuna roll, perfect as a quick snack or elegant appetizer. It combines flaky tuna with a creamy, spicy dressing atop crisp cucumber slices for a burst of flavor and texture.
For 4 servings
Thoroughly drain the canned tuna. Press out as much liquid as possible using a fine-mesh sieve or by squeezing it in a paper towel. This prevents the tuna mixture from becoming watery.
In a medium bowl, combine the drained tuna, mayonnaise (or Greek yogurt), sriracha, toasted sesame oil, and low-sodium soy sauce. Add the thinly sliced green onion.
Using a fork, gently mix all the ingredients until well combined. Be careful not to overmix, as this can make the tuna mushy. The mixture should be creamy but still have some texture.
Taste the tuna mixture and adjust seasonings as needed. You might want to add more sriracha for extra heat, a touch more soy sauce for saltiness, or a pinch of salt and black pepper.
Prepare the cucumber by washing it thoroughly. Using a sharp knife or a mandoline, slice the English cucumber into uniform ¼-inch thick rounds. For best presentation, try to keep the slices consistent.
Arrange the cucumber rounds in a single layer on a serving platter. Using a small spoon or a piping bag, dollop about 1-2 tablespoons of the spicy tuna mixture onto the center of each cucumber slice.
Garnish each spicy tuna bite with a sprinkle of black sesame seeds, if desired, for added visual appeal and a subtle nutty crunch.
Serve immediately for optimal freshness and crispness. If preparing slightly ahead, keep the tuna mixture and cucumber slices separate and assemble just before serving.
What to keep in mind.
4 tips from the recipe — small details that make a real difference to the final dish.
- 1**Drain Tuna Thoroughly:** This is crucial for a non-soggy mixture. Excess moisture can dilute the flavor and make the texture unappealing.
- 2**Adjust Spice Level:** Sriracha can be increased or decreased to suit your preference. For more heat, add a pinch of red pepper flakes. For less, start with half the amount and add gradually.
- 3**Chill for Best Flavor:** While delicious immediately, chilling the tuna mixture for 15-20 minutes before serving allows the flavors to meld beautifully.
- 4**Uniform Cucumber Slices:** Using a mandoline ensures all cucumber slices are the same thickness, providing a consistent bite and a professional presentation.
