Cilantro-Lime Sauce
This sauce lives in the space between a salsa and a vinaigrette—it's thicker than either, clings to food, and doesn't separate. The cilantro stays fresh because you're not cooking it, just pulsing it into submission with lime and fat. Make it right before you need it.
Cilantro amount matters more than you think
This sauce lives or dies on cilantro volume. Don't be timid. You need enough to actually taste the herb, not just catch a whisper of it. If you're using a food processor, pack the leaves loosely—they compress under the blade.

What goes in.
- 2 cupsfresh cilantro leaves, loosely packed
- 1lime, juiced
- 2 clovesgarlic, minced
- ½ cupneutral oil (vegetable, canola, or light olive oil)
- ¼ cupsour cream or Greek yogurt (optional, for creamier texture)
- ½ tspsalt
- ¼ tspground cumin (optional)
- pinchred pepper flakes (optional)
Don't overblend — emulsion matters
The sauce should be smooth but still have a slight body and texture. Overblending breaks the emulsion and turns it thin and watery. Pulse the cilantro and garlic first, then drizzle in the oil slowly while the processor runs. Stop as soon as you've reached your desired texture.
The method.
Remove cilantro leaves from stems
Discard the tough stems and rinse the leaves. Pat them dry with paper towels—water will dilute your sauce.
Add cilantro, garlic, lime juice, and salt to the food processor
Pulse 3 or 4 times until the cilantro is chopped fine but still has visible flecks. Don't fully process it yet.
With the processor running, add oil slowly
Start with a thin stream. Add about half the oil, let it incorporate fully (15–20 seconds), then add the rest. This creates emulsion instead of separation.
Add sour cream or yogurt if using
Pulse to combine. This adds body and softens the edge of the cilantro. Skip this if you want a thinner, oil-based sauce.
Taste and adjust
Add a pinch more salt if needed. If the cilantro taste is faint, you can add a small handful more of leaves and pulse again. Taste for balance between acid, salt, and herb.
Transfer to a bowl or jar
Use immediately or refrigerate for up to 3 days. The color will darken and the flavor will flatten slightly, so fresh is always better.
Other turns to take.
Creamy cilantro-lime
Use ¾ cup sour cream or Greek yogurt and reduce oil to ¼ cup. This makes a thicker, almost dressing-like sauce that works well on roasted vegetables or as a dip.
With jalapeño
Add 1 fresh jalapeño (seeds removed if you want less heat) to the processor with the cilantro. Pulse until incorporated. The chile adds depth without overwhelming the lime.
With avocado
Blend ½ ripe avocado into the finished sauce for a creamier, richer version. It dulls the brightness slightly, so increase the lime juice by a squeeze.
With cotija or feta
Fold in ¼ cup crumbled cotija cheese or feta after blending. This makes a chunkier, more substantial sauce for tacos or grilled meats.
Vietnamese-style (with mint)
Replace half the cilantro with fresh mint. Add a tablespoon of fish sauce instead of salt. This shifts the profile toward Southeast Asian flavor.
When it doesn't go to plan.
Make the sauce just before serving. The cilantro flavor fades and the color dulls after a few hours, even covered in the fridge.
If your sauce breaks and separates, pour it out, start fresh with a small amount of sour cream in the processor, then drizzle in the separated mixture slowly while it runs.
Taste the lime juice before adding it—store-bought limes vary wildly in acidity. You may need half a lime or a whole one depending on size and freshness.
For a silkier sauce without a food processor, mince the cilantro and garlic by hand on a cutting board as fine as you can, then whisk in the oil and lime juice slowly in a bowl.
The sauce will be brighter and more vivid if you use cilantro that's been chilled. Let it sit in the fridge for an hour before processing if you have time.
The ones that keep coming up.
Can I make this ahead?
You can prep the cilantro and lime juice several hours in advance, but blend them only right before serving. The cilantro oxidizes and loses its fresh flavor within a few hours of blending.
What if I don't have a food processor?
Mince the cilantro and garlic as finely as possible by hand, then whisk the lime juice, salt, and garlic together in a bowl. Slowly whisk in the oil until it emulsifies into a loose sauce. It won't be perfectly smooth, but the flavor is just as good.
How much sauce do I need per serving?
Figure on about 2 to 3 tablespoons per person as a condiment. If you're using it as a dressing for a grain bowl or salad, you'll want closer to ¼ cup per serving.
Can I use dried cilantro?
No. Dried cilantro tastes dusty and bitter. If fresh cilantro isn't available, substitute fresh parsley and a small amount of ground coriander, or skip the sauce entirely.
What pairs well with this sauce?
Fish tacos, grilled chicken, roasted shrimp, grain bowls, roasted root vegetables, quesadillas, and ceviche all benefit from it. Anywhere you'd use salsa or a bright dressing works.
