This vibrant Mexican-inspired sauce comes together in just 10 minutes with no cooking required. The creamy base combines sour cream and mayonnaise with fresh cilantro, zesty lime juice, garlic, and a hint of cumin. Perfect for drizzling over tacos, grilled meats, salads, or using as a dip.
The sauce is easily customizable—add jalapeño for heat or adjust the consistency with water or milk. It stores well in the refrigerator for up to 4 days, making it perfect for meal prep. Vegan-friendly substitutions are simple using plant-based yogurt and mayonnaise.
The smell of cilantro has always divided people in my kitchen, but this sauce converted even the most skeptical friend at my table during a chaotic taco Tuesday that involved a broken blender lid and sauce on the ceiling.
I started making double batches after my neighbor wandered over asking what smelled so good and ended up eating half the bowl with tortilla chips before dinner was even ready.
Ingredients
- Sour cream (or Greek yogurt): The backbone of creaminess, and Greek yogurt swaps in beautifully if you want something lighter with extra tang.
- Mayonnaise: Adds richness and body that sour cream alone cannot quite achieve.
- Fresh cilantro leaves: Use a full loosely packed cup because it wilts down dramatically during blending.
- Fresh lime juice: One lime usually does it, but taste as you go since limes vary wildly in acidity.
- Garlic clove: Keep it to one small clove so it does not overpower the delicate herb flavor.
- Jalapeño (optional): Seed it for gentle warmth or leave some seeds in if you like a kick.
- Ground cumin: A quarter teaspoon adds earthy depth without screaming cumin.
- Sea salt and black pepper: Essential for waking up every other flavor in the blend.
- Water or milk: Added gradually to thin the sauce to whatever consistency suits your dish.
Instructions
- Load everything in:
- Toss the sour cream, mayonnaise, cilantro, lime juice, garlic, jalapeño, cumin, salt, and pepper straight into your blender or food processor without overthinking it.
- Blend until silky:
- Run the machine until you see a smooth, uniformly green sauce, stopping to scrape down the sides once or twice so nothing escapes the blades.
- Thin it out:
- Add water or milk one tablespoon at a time and blend briefly after each addition until the sauce pours the way you want it to.
- Taste and tweak:
- Give it a sample on a spoon and adjust salt, lime, or cumin before you commit to serving it.
- Chill before serving:
- Transfer to a jar, cover it tight, and let it rest in the fridge for at least thirty minutes so the flavors settle into something greater than their parts.
The night I served this drizzled over grilled street corn at a backyard gathering, three people asked for the recipe before they even finished eating.
Making It Your Own
Swap the sour cream for coconut cream and use vegan mayo to make a fully plant based version that tastes nearly identical to the original.
Storing Leftovers
Kept in an airtight jar in the refrigerator, this sauce holds up beautifully for up to four days, though the color may darken slightly on top.
Ways To Use It All Week
Beyond tacos, I have spooned it over grain bowls, used it as a salad dressing, and dunked roasted sweet potato fries into it with zero regrets.
- Thin it further with a splash of buttermilk for an incredible salad dressing.
- Dot it onto scrambled eggs for a breakfast upgrade that feels almost too easy.
- Always stir gently before serving since separation is natural and harmless.
Once you have a jar of this sitting in your fridge, you will start looking for excuses to put it on everything.
