Ingredients for cucumber salad recipe with soy sauce and vinegar
Simple ingredients transform into a vibrant Asian-inspired salad with perfect crunch and umami balance.
| Ingredient | Amount | Notes |
|---|---|---|
| Persian Cucumbers 🥒 | 2 lb | Thinly sliced lengthwise, seeds removed |
| Rice Vinegar 🍶 | ½ cup | Seasoned preferred for depth |
| Low-Sodium Soy Sauce 🍶 | 2 tbsp | Kikkoman or San-J preferred |
| Toasted Sesame Oil 🫒 | 1 tbsp | High-quality, nutty aroma |
| Garlic Cloves 🧄 | 3 cloves | Finely minced, fresh preferred |
| Granulated Sugar 🍚 | 1 tbsp | Balances acidity perfectly |
| Toasted Sesame Seeds 🌾 | 1 tbsp | For garnish and texture |
| Red Onion 🧅 | ¼ cup | Thinly sliced, optional |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | Adjusts seasoning balance |
| Fresh Ginger 🌿 | 1 tsp | Grated, adds subtle warmth |
| Red Chili Flakes 🌶️ | ¼ tsp | Optional for heat |
| Extra-Firm Tofu 🍱 | ½ lb | Pressed and cubed, optional protein |
The quality of your cucumbers matters most—Persian cucumbers with thin skins and minimal seeds create the ideal texture. Whole Foods or local farms often carry the best varieties, but any firm, straight cucumbers work. Avoid those with soft spots or yellowing ends. For the dressing, seasoned rice vinegar adds subtle sweetness, but plain vinegar works with an extra half-teaspoon sugar. The soy sauce should be low-sodium to prevent over-salting, and Kikkoman or San-J brands deliver consistent flavor. Toast your sesame oil in a dry pan for 30 seconds before using—this deepens its nutty aroma without burning.
No sesame oil? Avocado oil or light olive oil works in a pinch, though the flavor won't be identical. Substitute maple syrup for sugar if you prefer a more refined sweetness, though granulated sugar dissolves more cleanly. Fresh ginger is ideal, but ground ginger at half the amount suffices. For the optional tofu, extra-firm holds shape best—press it for 15 minutes between paper towels to remove excess moisture. The red onion adds brightness; if you skip it, increase the garlic slightly for depth. All ingredients should be measured precisely except the cucumbers, which can be eyeballed for thickness—aim for paper-thin slices that won't overpower the dressing.
This salad stays crispest when refrigerated for 1-2 hours before serving, allowing flavors to meld without wilting. Store leftovers in an airtight container with parchment between layers to prevent sogginess—keeps for 3 days. For meal prep, assemble the dressing separately and toss with cucumbers just before serving to maintain texture. The tofu, if included, can be pressed and cubed a day ahead. Garnish with extra sesame seeds and chili flakes right before serving for maximum freshness and visual appeal.
Why You'll Love This Recipe
- Five-Ingredient Magic: I swear by this combo—Persian cucumbers sliced thin, a splash of rice vinegar, a dash of soy, sesame oil, and minced garlic. It’s the kind of recipe where you don’t even need a measuring cup.
- Umami Crunch Perfection: That first bite? The crisp cucumbers cut through the tangy-savory punch of soy and vinegar, while the garlic and sesame oil add depth. It’s refreshing, but it’s also weirdly satisfying—like a palate reset in salad form.
- Picnic to Potluck: This holds up everywhere. Pack it in a jar for lunch, bring it to a BBQ, or serve it alongside grilled fish. Honestly, I’ve had it at all three—no one’s ever questioned why it’s on the table.
- No-Waste Leftovers: The flavors actually improve after a day in the fridge. The cucumbers soften just enough to soak up the dressing, and it’s still crisp enough to eat cold. My go-to for lazy nights when I’ve got half a head of garlic left.
Step-by-step instructions for Asian-inspired cucumber salad
This quick, vibrant salad balances crisp cucumbers with bold Asian flavors in just minutes.
Prepare the Cucumber and Tofu
Start by thinly slicing the 2 lb Persian cucumbers lengthwise using a sharp mandoline or knife. Remove seeds if present—they can make the salad bitter. For the 0.5 lb extra-firm tofu, press it between paper towels for 15 minutes to remove excess moisture, then cube into ½-inch pieces and pat dry. This step ensures your tofu won't turn mushy in the dressing.
Place the cucumber slices and tofu cubes in a large mixing bowl. If using, thinly slice the 0.25 cup red onion and add it to the bowl. The onion adds a bright, sharp contrast that cuts through the richness of the dressing. Keep everything separate for now—we'll combine it all in the next step.
Make the Flavorful Dressing
In a small bowl, whisk together the 0.5 cup rice vinegar, 2 tbsp low-sodium soy sauce, 1 tbsp granulated sugar, 1 tbsp toasted sesame oil, 3 cloves finely minced garlic, 1 tsp grated fresh ginger, 0.5 tsp Diamond Crystal kosher salt, and 0.25 tsp red chili flakes (if using). The sugar balances the acidity of the vinegar, while the garlic and ginger add depth. Stir until the sugar fully dissolves—this ensures even distribution of flavor.
Taste the dressing and adjust seasoning if needed. If it's too sharp, add a pinch more sugar. If it lacks brightness, a splash of extra rice vinegar helps. The dressing should coat the back of a spoon with a glossy sheen, indicating it's ready to marinate the vegetables.
Combine and Marinate
Pour the dressing over the cucumbers, tofu, and onion in the mixing bowl. Use a pair of tongs or clean hands to gently toss everything until the vegetables are evenly coated. Avoid overmixing—the cucumbers should remain crisp, not bruised. Let the salad sit for 10 minutes at room temperature to allow the flavors to meld.
While it marinates, toast the 1 tbsp toasted sesame seeds in a dry skillet over low heat for 1-2 minutes until fragrant. This step enhances their nutty aroma, which will elevate the salad's final presentation. Sprinkle the seeds over the salad just before serving to keep them crisp.
Serve Immediately for Best Texture
Give the salad one final toss with tongs to redistribute the dressing. Serve it chilled or at room temperature, garnished with the toasted sesame seeds. The cucumbers should remain crisp with a slight bite, while the tofu absorbs the dressing without becoming soggy. For extra crunch, serve alongside warm rice or grilled proteins.
This salad keeps well in the refrigerator for up to 2 days, though the cucumbers may soften slightly over time. If storing, keep the tofu and cucumbers separate until ready to serve to maintain texture. The dressing can be made ahead and stored separately for up to 3 days.
Pro Tips For Making Cucumber Salad Recipe With Soy Sauce And Vinegar
- Slice Thin, Then Toss: Persian cucumbers have thick skins and watery centers—if you cut them into thick rounds, they’ll turn mushy fast. Grab a sharp knife, hold the cucumber at a 45-degree angle, and slice paper-thin (about ⅛-inch). Toss them immediately with the dressing so they soak up flavor instead of sitting in their own juices.
- Salt the Cucumbers First: I learned this the hard way—skipping the salt step means your salad gets soggy. Sprinkle the sliced cucumbers with ½ teaspoon of salt (yes, even low-sodium soy sauce counts) and let them sit for 10 minutes in a colander. This draws out excess water so the dressing clings instead of pooling.
- Toast the Garlic Separately: Raw garlic in this salad can taste harsh, especially if you’re not a fan of its bite. Instead of mincing it raw, lightly toast 1-2 cloves in a dry pan over medium heat until fragrant (about 2 minutes). Smash them with the flat of your knife, then mix into the dressing—it mellows the flavor and adds depth without overpowering.
- Dress It Just Before Serving: This isn’t a make-ahead dish unless you want a sad, wilted mess. Combine the rice vinegar, soy sauce, sesame oil, and toasted garlic right before tossing with the cucumbers. If you mix it too early, the cucumbers will turn limp, and the sesame oil will separate. Wait until the last 5 minutes—your taste buds will notice the difference.
Storing and reheating this dish
Refrigerator Storage
Store your cucumber salad in an airtight container with parchment paper between layers to preserve crispness. I always use glass containers (like Pyrex) because they keep the salad fresher longer than plastic.
Keep it refrigerated at 40°F or below for up to 3 days, though I find it’s best enjoyed within 2 days for peak texture. The cucumbers will soften slightly over time, but the flavors remain vibrant. 🥒
Freezing Considerations
This salad isn’t ideal for freezing because cucumbers release water and turn mushy. However, you can freeze the dressing separately for up to 3 months—just whisk it with fresh cucumbers when ready to serve.
For the tofu (if included), press and cube it ahead, then freeze in a single layer before transferring to a bag. Thaw overnight in the fridge before using. ❄️
Reheating for Texture
If your salad sits too long and loses crispness, revive it by tossing with 1 tsp fresh lime juice and a pinch of salt. For tofu, reheat it separately in a dry skillet over medium heat for 2-3 minutes until lightly crispy.
Never microwave the cucumbers—they’ll turn rubbery. A quick chilling in ice water for 5 minutes can also help restore crunch. 💡
Meal Prep Strategy
Prepare the dressing and chop the cucumbers separately, then combine just before serving. This keeps the cucumbers crisp for up to 4 days in the fridge. Store the tofu (if using) in a separate container with a paper towel to absorb moisture.
When ready to eat, toss everything together and garnish with toasted sesame seeds for that fresh-off-the-table look. 📅
Serving Leftovers
Leftovers make a fantastic next-day lunch or potluck side. Serve chilled over warm rice or alongside grilled proteins like chicken or fish. For extra flair, drizzle with a little extra sesame oil and sprinkle with red chili flakes to reignite the flavors.
The contrast of warm and cold makes it feel like a brand-new dish! 🍚

Frequently asked questions
Can I substitute white vinegar for rice vinegar?
Yes, but you'll need to adjust the flavor balance. Use the same amount of white vinegar, but add an extra ½ teaspoon of sugar to compensate for its sharper acidity. For best results, marinate the salad for 15 minutes instead of 10 to let the flavors meld. The salad will still taste great, but it'll have a slightly more tangy profile.
Why do my cucumbers turn soggy in the dressing?
This happens when cucumbers release too much moisture or sit too long. To prevent it, slice cucumbers thinly but remove all seeds first. Toss the salad just before serving and store components separately if prepping ahead. For extra crispness, chill the salad for 1 hour before eating—cold temperatures help maintain texture.
Is this recipe vegan-friendly?
Not as written, but it's easily adaptable! Replace soy sauce with tamari or coconut aminos for vegan umami. Use maple syrup instead of granulated sugar, and ensure your sesame oil is vegan-certified. The tofu can be omitted entirely for a fully plant-based version. The core flavors remain the same—just check each ingredient label.
How spicy should the red chili flakes be?
Start with ¼ teaspoon for mild heat, or use ½ teaspoon for noticeable spice. For extra kick, add 1 minced fresh chili (like jalapeño) to the dressing. Remove seeds before chopping to control heat intensity. The chili flakes add subtle warmth—adjust based on your spice tolerance!
Can I make this salad without tofu?
The tofu adds protein but isn't essential. For a lighter version, simply omit it and increase cucumber quantity to 2.5 lbs for the same serving size. Add ½ cup diced bell peppers or ¼ cup chopped cilantro for extra texture and freshness. The dressing-to-veggie ratio remains the same—just scale up slightly.
