Ingredients for blue sushi cucumber salad
Crisp veggies meet vibrant blue magic for a salad that’s as stunning as it is delicious.
| Ingredient | Amount | Notes |
|---|---|---|
| Persian Cucumbers 🥒 | 2 whole | Thinly sliced, seeds removed |
| Celery Stalks 🧅 | 3 whole | Thinly sliced into crowns |
| Butterfly Pea Flower Tea 🌸 | 1 tbsp | For vibrant blue hue |
| Rice Vinegar 💧 | ⅓ cup | Unseasoned, mild flavor |
| Sesame Oil 🫒 | 2 tbsp | Toasted for nutty aroma |
| Raw Honey 🍯 | 1 tbsp | Substitute agave for vegan |
| Toasted Sesame Seeds 🌰 | 1 tbsp | For crunchy garnish |
| Pickled Ginger 🍶 | 2 tbsp | Finely chopped, optional |
| Fresh Mint Leaves 🌿 | ¼ cup | Chopped for brightness |

The Persian cucumbers are non-negotiable here—their thin skin and crisp texture hold up beautifully. Grab the organic variety at Whole Foods if you can, but any Persian cucumber works. For the celery crowns, look for stalks with vibrant green tops and firm, crisp stems—Trader Joe's usually carries perfect ones. Butterfly pea flower tea is the secret ingredient; you can find it at Asian markets or online. If you can't find it, blue spirulina powder works in a pinch, but the flavor won't be as delicate. The rice vinegar should be unseasoned—Kikkoman is my go-to, but any mild white vinegar will do if you're in a bind.
No sesame oil? Toasted sesame seeds plus a splash of neutral oil gets you close, though the flavor won't be as rich. Want to skip the honey? Agave nectar or maple syrup keeps it vegan-friendly without sacrificing sweetness. The pickled ginger adds a tangy kick—if you can't find it, substitute with extra lime juice and a pinch of ginger powder. For extra crunch, toast your sesame seeds in a dry pan for 2-3 minutes until fragrant. The red bell pepper is optional but adds a pop of color and a slight sweetness that balances the tangy dressing perfectly.
Store the cucumbers and celery crowns in airtight containers with a paper towel to absorb moisture—keeps them crisp for 3-4 days. The dressing should be made fresh and stored separately; it'll last 5 days in the fridge, but the butterfly pea tea's color fades over time. For a quick assembly, prep the veggies and dressing ahead, then toss just before serving. This salad is a showstopper, so wait until the last minute to garnish with sesame seeds and mint—they wilt fast once chopped. Perfect for meal prep, but the blue hue is best enjoyed fresh!

Step-by-step instructions for blue sushi cucumber salad
Here's how to create this vibrant, refreshing salad with perfect texture and balance.
Prepare the Vegetable Base
Start by thinly slicing the 2 whole Persian cucumbers lengthwise, removing seeds with a spoon to keep them crisp. I use a sharp mandoline for even slices—about ⅛-inch thick. Transfer to a large mixing bowl and set aside. Next, trim the ends from the 3 whole celery stalks and slice each into ¼-inch thick crowns using a sharp chef's knife. You're aiming for delicate, crisp pieces that won't overpower the salad.
Add the celery crowns to the cucumbers. If using the optional 0.25 cup red bell pepper, thinly slice it and add now. The vegetables should look fresh and vibrant—this is your foundation. I like to give them a gentle toss with my hands to distribute any juices that might release during slicing. This helps everything meld together perfectly when we add the dressing.
Create the Signature Blue Dressing
In a small saucepan, combine the 0.33 cup rice vinegar, 1 tbsp raw honey, 1 tbsp fresh lime juice, and 0.5 tsp Diamond Crystal kosher salt. Bring to a gentle simmer over medium-low heat for 2-3 minutes until the honey dissolves completely. Remove from heat and let cool for 5 minutes—this prevents shocking the delicate vegetables.
While the dressing cools, steep the 1 tbsp butterfly pea flower tea in ¼ cup hot water for 5 minutes until it develops a deep blue hue. Strain through a fine-mesh sieve to remove any plant matter. Once your vinegar mixture has cooled to room temperature, whisk in the blue tea and 2 tbsp sesame oil until fully emulsified. The dressing should be smooth with a vibrant blue tint—this is what makes this salad truly special.
Combine and Season
Pour the blue dressing over the cucumber and celery mixture in the mixing bowl. Add the 0.25 cup chopped fresh mint leaves and 2 tbsp finely chopped pickled ginger (if using). Gently fold everything together with a silicone spatula, being careful not to bruise the vegetables. The salad should look like a beautiful blue-green medley with bright pops of color from the mint and ginger.
Taste and adjust seasoning if needed—you might want to add a pinch more salt or a splash of lime juice to balance the flavors. I usually let it sit for 10 minutes at room temperature before serving. This allows the flavors to meld together perfectly while keeping the vegetables crisp. The blue color will intensify slightly as it sits, creating that stunning presentation.
Garnish and Serve
Transfer the salad to a serving platter or individual bowls. Sprinkle generously with 1 tbsp toasted sesame seeds for texture and visual appeal. The seeds should be evenly distributed—this adds a beautiful contrast to the smooth vegetables and vibrant blue dressing.
Serve immediately while the vegetables are at their peak crispness. This salad pairs beautifully with sushi, grilled fish, or as a refreshing appetizer. The balance of sweet, tangy, and umami flavors makes it incredibly satisfying. For extra presentation, I sometimes arrange the celery crowns artistically around the edge of the platter—it looks stunning and makes the dish feel special.
Pro Tips For Making Blue Sushi Cucumber Salad
- CHOP CELERY LENGTHWISE FIRST: Thin celery sticks take forever to cut crosswise, and they’ll get mushy if you force it. Slice the stalks lengthwise into ¼-inch strips first—then stack them and cut crosswise. You’ll save time and keep the texture crisp. (Yes, even if you’re impatient like me.)
- SALT CUCS BEFORE SLICING: Persian cucumbers bleed like crazy when sliced raw. Toss them with ½ teaspoon salt and let sit for 10 minutes in a colander—this draws out excess water so they stay firm and don’t turn into soup. Rinse just before slicing, or they’ll taste like a pickle.
- STEEP TEA COOL, NOT HOT: Butterfly pea tea needs to be ice-cold to work its magic—hot tea will cook the cucumbers into mush. Brew it, then dump the bags into a bowl of ice water for 5 minutes. Strain, and use the chilled liquid straight from the fridge. (No, room temp won’t cut it.)
- DRIZZLE SESAME OIL LAST: Sesame oil smells amazing but burns off fast. Add it after everything’s tossed and just before serving—about 1 teaspoon, swirled in gently. If you mix it in early, the heat will turn it bitter, and you’ll waste good oil. (Trust me, I’ve done it.)
Make-ahead tips for leftovers
Prep Components Separately
Slice the Persian cucumbers and celery crowns up to 2 days ahead—store them in airtight containers lined with paper towels to absorb moisture. The key is keeping them bone-dry to prevent sogginess. I like to portion them into quart-sized containers so they’re ready to toss with dressing in minutes.
The celery stays crisp for 3 days this way, while cucumbers hold up for 2 days before turning limp. 🥒
Dressing Prep Ahead
Make the blue dressing the night before and store it in a small sealed jar in the fridge. The butterfly pea flower tea will fade slightly but still delivers that magical blue tint. Whisk in the sesame oil fresh before tossing—this prevents separation.
The dressing keeps for 5 days, but I recommend using it within 3 days for maximum vibrancy. Pro tip: Label it clearly—this isn’t your average rice vinegar dressing! 💧
Garnish Last Minute
Toast the sesame seeds and chop the fresh mint just before serving—they lose their crispness and aroma when prepped ahead. I keep these components separate until the final moment to preserve their freshness.
The pickled ginger can be pre-chopped and stored in the fridge for 3 days, but its bright flavor peaks when added fresh. This ensures your salad looks and tastes restaurant-quality every time. ✨
Portion for Parties
For gatherings, assemble individual portions in clear glass bowls and store them in the fridge. The blue hue looks stunning through glass, and guests can customize their garnishes. Keep the toasted sesame seeds and mint leaves in small bowls nearby so everyone can add their own touch.
This method works perfectly for buffet-style serving—just arrange the bowls on a platter with fresh garnishes. 🍽️
Freezer-Friendly Base
While the full salad doesn’t freeze well, you can freeze the vegetable base (without dressing) for 1 month. Pack it tightly in a freezer bag, squeezing out all air to prevent ice crystals.
Thaw overnight in the fridge, then toss with fresh dressing. This is a lifesaver for busy weeks—just add the dressing and garnishes when ready to serve. The texture stays crisp when handled this way. ❄️
Color Preservation
To maintain the vibrant blue hue, avoid exposing the salad to metal utensils—they can react with the butterfly pea tea. Use silicon spatulas or wooden spoons when tossing. Also, store the dressing in amber or opaque containers to block light, which causes the color to fade faster.
If the blue dims, a splash of lemon juice can help restore it temporarily. Trust me, this little effort makes all the difference! 💫

Frequently asked questions
Can I make this salad without butterfly pea flower tea?
Yes! If you can't find butterfly pea flower tea, try blue spirulina powder (⅛ tsp dissolved in warm water) or a pinch of blue food coloring (use sparingly). For a natural alternative, lightly steam red cabbage until it turns blue-purple, then blend into the dressing. The flavor won't be identical, but you'll still get that stunning blue effect.
How do I keep the celery crowns extra crisp?
Soak the celery crowns in ice water for 10 minutes before slicing to maintain crispness. After slicing, pat them completely dry with paper towels and store in an airtight container with a paper towel to absorb moisture. For even more crunch, sprinkle with 1 tsp cornstarch before adding the dressing—it creates a light coating that preserves texture.
Is this salad safe for kids or picky eaters?
Skip the butterfly pea tea and use regular rice vinegar dressing instead. For extra appeal, serve the cucumbers and celery crowns separately with a small bowl of dressing on the side. Kids often prefer to dip their veggies rather than eat them mixed. You can also add mandarin orange segments for sweetness or crumbled feta cheese for a familiar flavor profile.
Can I use regular cucumbers instead of Persian cucumbers?
While Persian cucumbers are ideal for their thin skin and seedless flesh, you can use regular cucumbers by peeling them first and removing all seeds. For extra crispness, soak the slices in cold water for 30 minutes before draining and adding to the salad. The texture won't be quite as delicate, but it'll still work well. For a compromise, try English cucumbers—they're seedless and have slightly thicker skin.
Why did my blue dressing turn purple instead of blue?
The color change happens when the pH shifts—common causes include adding too much lime juice or using metal utensils. For a true blue, use lemon juice instead of lime (it's less acidic) and stir with a wooden or silicone spoon. If it's already purple, add a pinch of baking soda (⅛ tsp) to restore the blue hue. The flavor won't be affected, just the color.
