How to Make Seared Ahi Tuna Cucumber Bites
-
Slice cucumbers: Begin by cutting the English cucumbers into even rounds, about ¼-inch thick. This creates a satisfying, crunchy base. If desired, sprinkle a little salt on them to help release moisture, then rinse and pat dry.
-
Prepare wasabi mayo: In a medium bowl, mix together the mayo, wasabi (paste, powder, or fresh), rice wine vinegar, salt, and sugar until everything is beautifully combined. Set this delightful blend aside to let the flavors meld.
-
Coat the tuna: Drizzle sesame oil over the sushi-grade ahi tuna, ensuring all sides are covered. Then, roll the tuna in a mix of white and black sesame seeds, coating it evenly for that perfect crunchy texture.
-
Sear the tuna: Heat a skillet or grill over medium-high heat. Sear the coated tuna for 20-30 seconds on each side, until it develops a light brown crust while remaining medium rare inside. Once done, remove from heat, allow to cool slightly, and slice into thin bites.
-
Assemble the bites: Arrange the cucumber slices on a serving platter, place the sliced seared tuna on top, and finish with a dollop of the prepared wasabi mayo. Add garnishes of chives and edible flowers for an extra touch of elegance and flavor. Serve immediately to enjoy!

Seared Ahi Tuna Cucumber Bites with Wasabi Mayo Recipe FAQs
How do I select the best sushi-grade ahi tuna?
Absolutely! When choosing sushi-grade ahi tuna, look for a vibrant, deep red color and a fresh, ocean-like smell. Avoid any pieces that have dark spots or unpleasant odors. Freshness is key, so don’t hesitate to ask your fishmonger about the sourcing and storage of the fish.
How should I store leftover Seared Ahi Tuna Cucumber Bites?
Great question! Leftover bites should be stored in an airtight container in the refrigerator and consumed within 1 day for the best taste and texture. To retain the crunchiness of the cucumbers, keep the wasabi mayo separate and add it just before serving.
Can I freeze the ahi tuna leftovers?
Yes, you can freeze leftover ahi tuna, but not in its assembled bite form. Wrap it tightly in plastic wrap or aluminum foil, then place it in a freezer-safe container. It can be frozen for up to 1 month. To enjoy, thaw in the refrigerator overnight and gently reheat, ensuring the fish remains tender.
What should I do if my seared tuna becomes overcooked?
Very! If your tuna is overcooked and too dry, you can try slicing it thinly and mixing it into a salad with a light vinaigrette to mask the dryness. Alternatively, use it to make a savory tuna salad by combining it with mayo, diced celery, and seasonings.
Are there any dietary restrictions I should consider with wasabi mayo?
Absolutely! For those with allergies to seafood or eggs, the wasabi mayo won’t be suitable—substitute it with avocado or hummus for a creamy base. Also, those sensitive to wasabi might want to adjust the amount or skip it altogether for a milder sauce.
What are some visual cues to watch for when a tuna is perfectly seared?
Trust your senses! A perfectly seared tuna will have a light brown crust on the outside, while the inside should still be a vibrant pink. The texture should be firm yet yielding to the touch. If the outside is getting too dark, lower your heat and adjust cooking time accordingly.
