This spicy Asian cucumber salad has been one of my go-to side dishes ever since I first tasted it at a neighborhood potluck hosted by a close friend. It arrived on the table cool, citrus-bright and with a surprising, lingering heat that made everyone reach for more. I recreated the combination at home using pantry staples and a few small adjustments, and the result quickly became my favorite way to brighten up weeknight dinners. The texture is what wins me over: thin, crisp cucumber slices that still retain crunch after a short salt soak, contrasted by a glossy, savory-sour-sweet dressing with a pleasant chili kick.

I first discovered this method during a particularly hot summer when heavy meals felt wrong and something light, spicy and fast was exactly what we needed. It’s become our summer staple at barbecues and a frequent accompaniment to fried rice, grilled fish, or simply a bowl of warm noodles. The salad is forgiving: it works with Persian cucumbers or mini cucumbers, and the dressing can be dialed up or down depending on how adventurous your guests are with heat. Every time I make it, someone asks for the recipe, and every time I watch the bowls returned empty.

Ingredients

• Mini cucumbers or Persian cucumbers: Use 6 small cucumbers for the crispest texture. Look for firm cucumbers with bright skin and no soft spots. Persian varieties are thin-skinned and less watery than supermarket slicing cucumbers, which helps prevent the salad from becoming soggy.
• Salt: 2 teaspoons coarse salt to draw out excess water quickly. Kosher or sea salt both work; this step firms the cucumbers and concentrates their flavor, but rinsing is essential afterward.
• Soy sauce: 1 tablespoon regular soy sauce provides savory umami. If you need a gluten-free option, swap for tamari and reduce by a small splash if you prefer less saltiness.
• Garlic: 2 cloves, minced very fine. Fresh garlic gives bright, pungent flavor—avoid pre-minced jars if you want the cleanest taste.
• Rice vinegar: 1 tablespoon for light, tangy acidity. White vinegar can be substituted if needed, but rice vinegar is milder and slightly sweeter.
• Chinese chili oil: 1 tablespoon for heat and chili flavor. Use a mild chili oil if you want warm heat or a fragrant, spicy chili crisp for texture and extra depth.
• Sugar: 1 tablespoon white granulated sugar to balance the acidity and salt.
• Sesame oil: 1 teaspoon toasted sesame oil for nutty aroma—add it last to preserve its fragrance.
• Sesame seeds: 1 teaspoon, toasted if possible to deepen flavor and add a slight crunch.
• Green onion: 2 tablespoons finely sliced for freshness and a mild oniony bite.

Instructions

Prepare cucumbers: Wash the cucumbers and trim the ends. For spiral-style slices, place a cucumber between two chopsticks and make thin diagonal cuts across the top without cutting through to the bottom; flip and repeat. Then cut each cucumber in half. If you prefer, slice thinly on a diagonal into half-moons. The chopstick trick helps create a decorative spiral while keeping pieces attached; do not angle your knife straight down or the spiral effect won’t form. Salt and rest: Sprinkle about 2 teaspoons of coarse salt over the sliced cucumbers and gently massage them for 20 to 30 seconds. Let them sit for 5 minutes but no longer than 10 to avoid breakdown. You’ll notice water pooling—this is the desired effect to firm the flesh and concentrate flavor. Rinse and drain: Rinse the cucumbers under cold running water three to four times to remove excess salt. Use a fine-mesh strainer or a slotted spoon to press out remaining water, then transfer to a large mixing bowl. Removing the salt prevents overly salty dressing and keeps the texture clean. Make dressing: In a small bowl combine 1 tablespoon soy sauce, 2 minced garlic cloves, 1 tablespoon rice vinegar, 1 tablespoon chili oil, 1 tablespoon sugar, 1 teaspoon sesame oil, 1 teaspoon sesame seeds and 2 tablespoons sliced green onion. Whisk until the sugar is dissolved and the flavors blend. Taste and adjust heat or acidity to preference. Dress and serve: Pour the dressing over the drained cucumbers and toss gently to coat without bruising. Let rest for 5 to 15 minutes to allow flavors to meld, then serve chilled. This salad is best eaten the same day for peak crispness.

Storage Tips

Store the salad in an airtight container in the refrigerator for up to 48 hours. To maintain the best texture, place a paper towel at the bottom of the container to absorb excess moisture. If you need to store longer, keep the cucumbers and dressing separate: refrigerate cucumbers in a sealed container and the dressing in a small jar; combine just before serving. Reheat is not recommended—this is a chilled side best served cold or at cool room temperature. When draining before serving, press gently with a spoon to remove pooled liquid.

Ingredient Substitutions

If you don’t have Chinese chili oil, substitute with a teaspoon or two of sambal oelek or a drizzle of sriracha mixed with a splash of neutral oil. For gluten-free needs, swap soy sauce for tamari. Omit sugar to reduce sweetness or replace with honey if you prefer a more floral note. If sesame oil is unavailable, use a small amount of walnut oil for a different nutty aroma, but add it sparingly since it is stronger. Freshly toasted sesame seeds elevate the finish; if using black sesame seeds, expect a slightly earthier look and taste.

Serving Suggestions

This salad pairs beautifully with grilled meats like chicken or shrimp, steamed rice bowls, or pan-fried fish. Serve it as a bright starter at a casual dinner or alongside heavier fried dishes to provide refreshing contrast. Garnish with extra sliced green onions, a few toasted sesame seeds, or a squeeze of lime for an added citrus lift. For a composed plate, serve the salad in small individual bowls so guests can nibble between bites of the main course.

Cultural Background

Light cucumber salads are common across East and Southeast Asia, where crunchy vegetables are often dressed with soy, vinegar, and sesame to create balanced accompaniments. The use of chili oil introduces Sichuan-style influence, while rice vinegar and sesame nod to broader regional tastes. These kinds of dressed vegetables are meant to be palate refreshers and are traditionally served with richer or spiced mains to cleanse the mouth between flavors.

Seasonal Adaptations

In summer, use the freshest local Persian cucumbers and increase the green onion to match bright garden flavors. In cooler months, add thinly sliced radish or blanched snap peas for texture. For a holiday twist, mix in finely julienned carrot and a touch more sugar to offset stronger meats. You can also swap rice vinegar for apple cider vinegar in colder months when pantry items vary.

Meal Prep Tips

For easy weekly sides, slice cucumbers and store them drained in a sealed container for up to a day, and keep the dressing in a small jar. Toss 10 to 15 minutes before serving to maintain crunch. Portion into individual containers for grab-and-go lunches. If taking it to a potluck, transport cucumbers and dressing separately and combine just before serving to avoid sogginess from travel.

With its quick preparation and big flavor, this salad is a reliable companion to many meals. Give it a try the next time you want something bright, spicy and effortless to serve—it's a small change that makes a big difference at the table.
