Pin to Board I discovered MSG wasn't a boogeyman but a gateway to something magical when a friend handed me a jar and said, "Just try it." That afternoon, I smashed cucumbers with the back of my knife—the satisfying crack of cold vegetables splitting under pressure—and sprinkled in a tiny pinch of that white powder. The taste transformed instantly: bright, salty, savory all at once, like someone had turned up the volume on flavor without adding a single loud ingredient. This cucumber salad became my go-to side, the one people always ask about, the one I make when I want something to taste effortlessly delicious.
My partner looked skeptical when I placed a tiny bowl of this beside grilled fish last summer, but by the end of dinner, the salad was nearly gone and he was asking for the recipe. There's something about cold, crunchy vegetables dressed in sesame oil and umami that just makes everything else taste better—it's the kind of side dish that quietly steals the show.
Ingredients
- 2 medium cucumbers, chilled: Cold cucumbers stay crunchier longer, so chill them before you start—this small step makes a real difference in texture.
- 2 spring onions, finely sliced: Their mild bite balances the umami, and slicing them thin lets them distribute evenly without overpowering the salad.
- 1 ½ teaspoons fine sea salt: This draws out the cucumber's water content and seasons them from within; don't skip the salting step.
- 2 teaspoons sugar: A tiny bit of sweetness rounds out the savory depth and keeps the salad from tasting flat.
- 1 tablespoon rice vinegar (unseasoned): The acidity brightens everything, and unseasoned vinegar gives you control over the final flavor.
- 1 tablespoon toasted sesame oil: Use the good stuff here—it's not just an ingredient, it's the backbone of the whole dish's warmth.
- 1 teaspoon MSG: This is your umami amplifier, making every other flavor pop without tasting salty or artificial.
- ½ teaspoon soy sauce: A small amount adds depth; use tamari if you need it gluten-free.
- 1 small garlic clove, finely minced: Garlic raw releases its sharpness slowly, so mince it fine so it blends in rather than attacking your palate.
- ¼ teaspoon white pepper (optional): It adds subtle heat without the color black pepper would leave behind.
- 1 teaspoon toasted sesame seeds (plus more for garnish): Toasted seeds have deeper flavor than raw ones and add a nutty complexity.
- 1–2 teaspoons chili crisp or chili oil (optional, to taste): This is for heat seekers; it also adds its own savory layer if you want it.
Instructions
- Prep and smash the cucumbers:
- Wash and dry them thoroughly, then slice off the ends and cut each in half lengthwise. Place the flat side of a chef's knife on the cucumber and press down firmly with the heel of your hand—you want them cracked but not pulverized. Cut the pieces into bite-sized chunks and put them in your bowl; this surface damage is what lets the seasoning really sink in.
- Draw out the water:
- Scatter the salt and sugar over the cucumbers and toss well, then walk away for 5 minutes. You'll see liquid pooling at the bottom—this is the cucumber releasing its excess moisture, which would dilute your dressing otherwise.
- Drain and season:
- Pour off the liquid (don't waste the flavor, just the excess water) and add the rice vinegar, sesame oil, MSG, soy sauce, minced garlic, white pepper if using, and sesame seeds. Toss everything together until each piece is coated and glistening.
- Optional heat and final touches:
- If you want chili crisp, add it now and fold it through, then stir in the spring onions right before serving so they stay fresh and bright. Taste as you go and adjust salt or vinegar if the balance feels off.
Pin to Board I served this at a casual weeknight dinner once, and a guest who'd always dismissed Asian flavors asked for my shopping list. Watching someone genuinely excited about a salad—reaching for another spoonful unbidden, tasting it slowly to understand why it was good—that's when I realized this wasn't just a side dish, it was a conversation starter.
The Magic of Umami
Umami is often explained in complicated ways, but really it's just savory depth—the flavor that makes you want another bite. In this salad, the MSG and sesame oil and soy sauce aren't competing; they're harmonizing, each one amplifying the others. Once you taste it this way, you understand why this particular combination has become viral: it's not a trend, it's just how food tastes best.
Why Smashing Matters
The smashing step isn't just for show—it's the difference between a salad that absorbs flavor and one that just sits there. When you crack the cucumber's surface, you're creating tiny valleys and crevices that hold onto oil and vinegar and salt. I learned this the hard way, making this salad the conventional way first, and the smashed version was leagues ahead in both texture and flavor absorption.
Serving and Storage
This salad is best served within an hour of assembly, when the cucumbers are still snappy and the aromatics haven't started to flatten. If you need to make it ahead, hold off on adding the spring onions and sesame seeds until the last moment—they stay fresher that way.
- Serve it cold or at room temperature, depending on what else is on the table.
- Leftovers keep for a day in the fridge, though the texture softens; they're still delicious over rice the next day.
- Double the recipe if you're feeding a crowd—it always disappears faster than you expect.
Pin to Board This salad taught me that cooking doesn't have to be complicated to be memorable. Sometimes the best food is just cold, crunchy, and deeply seasoned—the kind of dish you return to again and again because it never gets old.
Common Questions
- → How do I prepare the cucumbers for this dish?
Slice the cucumbers lengthwise and gently smash them with a rolling pin or knife flat side. Then cut into bite-sized pieces to help flavors absorb better.
- → Can I make this dish spicier?
Yes, you can add chili crisp or chili oil according to your taste for a spicy kick that complements the tangy flavors.

Chilling for about 10 to 15 minutes enhances the crunch and allows flavors to meld nicely before serving.
