Cambodian Salad Dressing Recipe: Lemongrass-Cilantro Zing for Fresh Spring Rolls

This Cambodian salad dressing recipe transforms simple greens into vibrant, tangy masterpieces—perfect for spring rolls, green papaya salad, or grilled meats. The secret lies in balancing bright lime juice, aromatic lemongrass, and fresh herbs with just the right touch of sweetness and umami from fish sauce.

I developed this version after years of testing, ensuring every spoonful delivers that signature Cambodian zing without overpowering delicate flavors.

The dressing comes together in minutes with simple ingredients you likely already have: lime juice, fish sauce (or vegan alternative), garlic, shallots, and a handful of cilantro and mint. The key is finely mincing the lemongrass and shallots—this creates a silky texture that coats every bite beautifully.

Unlike store-bought versions, this recipe stays fresh for days, making it ideal for meal prep or entertaining.

What makes this dressing truly special is its versatility. Drizzle it over fresh spring rolls for an authentic touch, toss it with shredded cabbage for a quick salad, or use it as a marinade for grilled shrimp.

The balance of tangy, sweet, and savory flavors elevates any dish while keeping the ingredients light and refreshing.

For best results, let the dressing sit for 15 minutes before using—this allows the flavors to meld and intensify. Store any leftovers in an airtight container in the fridge for up to 5 days, though I doubt it’ll last that long. Here’s how to make it perfectly every time.

Simple ingredients that pack bold Cambodian flavors for spring rolls and salads.

The fish sauce is non-negotiable for that signature umami punch—Red Boat is the gold standard, but any high-quality brand works. Look for one that’s aged at least 3 years for deeper flavor. Lemongrass can be tricky to find fresh, so Asian markets are your best bet. If you can only grab dried, it’s better than nothing, but fresh is worth the hunt. Shallots should be firm and pale—avoid any with green sprouts. For the herbs, Thai basil can substitute for cilantro if you’re feeling adventurous, but stick to regular cilantro for authenticity.

No fish sauce? Soy sauce or vegan fish sauce works in a pinch, though the flavor will differ slightly. Fresh herbs wilt fast, so chop them last minute if you’re not using the dressing immediately. The palm sugar adds just enough sweetness to balance the tang—brown sugar or coconut sugar are fine substitutes. For extra zing, add a pinch of chili flakes or a dash of Sriracha. The olive oil should be light and fruity; avoid heavy extra-virgin varieties that might overpower the delicate flavors. If the dressing seems too thick after blending, add water 1 tbsp at a time until it reaches your desired consistency.

This dressing keeps beautifully in an airtight container for 5-7 days in the fridge. The flavors actually deepen over time, so it’s perfect for meal prep. For longer storage, freeze in ice cube trays—just thaw and stir before using. If you make a big batch, portion it into small jars for easy grab-and-go use. The dressing works best when allowed to sit for 15-20 minutes before using, letting the flavors meld and intensify. Trust me, the wait is worth it for that restaurant-quality zing.

Step-by-step instructions for Cambodian salad dressing

This vibrant dressing balances bright citrus, fragrant herbs, and savory depth for spring rolls.

In a small bowl, combine the 3 cloves minced lemongrass, 3 cloves minced garlic, and 3 whole minced shallots. Let this mixture sit for 5 minutes at room temperature to release their essential oils. This step develops the foundational flavor that will carry through the dressing.

I like to use a mortar and pestle for this part—it creates a finer texture and helps release more of the aromatic compounds. If you don't have one, a small bowl with a fork works fine. The shallots should be finely minced so they dissolve completely into the dressing rather than remaining as distinct pieces.

Add the 0.5 cup fresh lime juice (strained to remove seeds), 0.5 cup fresh chopped cilantro, and 0.25 cup fresh chopped mint leaves to the lemongrass mixture. Stir thoroughly to combine all ingredients. The lime juice will immediately brighten the flavors, while the herbs add freshness and complexity.

Here's where it gets interesting—the combination of cilantro and mint creates that signature Cambodian flavor profile. Don't skip the stems on the cilantro; they contain concentrated flavor. If you're using particularly strong mint, you might want to reduce the amount slightly to avoid overpowering the other ingredients.

In a separate small bowl, whisk together the 2 tbsp fish sauce and 2 tsp palm sugar until the sugar dissolves completely. This mixture should taste balanced—salty from the fish sauce and sweet from the palm sugar. Add this to the herb mixture and stir well to combine.

The fish sauce is crucial here—it provides that umami depth that's characteristic of Southeast Asian dressings. I always use Red Boat brand for its clean, authentic flavor. If you're concerned about the dressing being too salty, you can taste as you go and adjust with a touch more sugar or a splash of lime juice.

With the motor running on low speed, slowly drizzle in the 0.25 cup extra-virgin olive oil while continuously blending. This gradual addition creates a stable emulsion. The dressing should thicken slightly but remain pourable. If it becomes too thick, add the 0.25 cup water one tablespoon at a time until you reach your desired consistency.

This is the moment that matters: the oil should blend smoothly without separating. If you're blending by hand, use a whisk and be patient—it takes about 2-3 minutes of vigorous whisking to achieve a proper emulsion. The final texture should coat the back of a spoon but still flow easily when drizzled.

Cover the dressing and let it rest at room temperature for 15-20 minutes. This resting period allows all the flavors to meld together. After resting, taste and adjust the seasoning if needed. You might want to add a bit more lime juice for brightness, a touch of sugar for sweetness, or a splash of water to thin it out.

I always find that the flavors develop more after resting. The dressing should be tangy from the lime, aromatic from the herbs, slightly sweet from the palm sugar, and savory from the fish sauce. This dressing keeps well in the refrigerator for up to 5 days, making it perfect for meal prep.

Creative variations of this dish

Spicy Chili Kick

For a fiery twist, add 1-2 teaspoons of sambal oelek or ½ teaspoon of chili flakes to the dressing after blending. This adds heat without overpowering the delicate balance of flavors.

I like to adjust the amount based on how spicy I want it—start with ½ teaspoon and taste before adding more. 🌶️

If you're using fresh chili peppers like Thai bird's eye, finely mince 1-2 peppers and add them to the lemongrass mixture at the beginning. This infuses the dressing with heat while keeping the texture smooth.

For a milder heat, use 1 teaspoon of Sriracha instead—it adds a touch of sweetness along with the spice.

Sweet and Tangy Twist

Swap the palm sugar for 1 teaspoon of honey or 1 teaspoon of coconut sugar to add a different depth of sweetness. The honey will create a smoother, more complex flavor profile that pairs beautifully with grilled meats or fresh spring rolls.

I find that honey works especially well if you're serving the dressing with fruit-based dishes like mango salad.

For extra tang, add 1 tablespoon of rice vinegar to the lime juice before blending. This adds a subtle sourness that cuts through the richness of the dressing, making it perfect for heartier dishes like grilled pork or beef.

The vinegar also helps balance the sweetness, creating a more nuanced flavor.

Herb Variations

Swap out the cilantro and mint for ½ cup of Thai basil to give the dressing a more aromatic, slightly peppery note. Thai basil works especially well if you're using this dressing with Vietnamese-inspired dishes.

For a more traditional Cambodian flavor, add 1 tablespoon of finely chopped galangal (also known as Thai ginger) to the lemongrass mixture—it adds a citrusy, piney aroma that's characteristic of Cambodian cuisine.

If you can't find fresh galangal, 1 teaspoon of grated fresh ginger works as a substitute, though it won't be quite as aromatic. Another great option is ½ cup of fresh perilla leaves (shiso), which add a unique, slightly minty flavor that pairs beautifully with the dressing.

These herb variations keep the dressing fresh and exciting while staying true to the Cambodian flavor profile.

Creamy Version

For a creamy twist, stir in 2 tablespoons of coconut milk or 1 tablespoon of Greek yogurt after blending. This adds a rich, velvety texture that works beautifully with dishes like grilled chicken or fresh spring rolls.

The coconut milk also enhances the tropical flavors, making it perfect for summer meals. 🥥

To keep the dressing light, use 1 tablespoon of coconut milk and thin it with an extra 1 tablespoon of water if needed. For a dairy-free option, coconut yogurt works just as well and adds a subtle sweetness that complements the dressing's tangy notes.

This creamy version is especially great for those who enjoy a balance of creamy and zesty flavors.
