Costco Cilantro Lime Crema (Easy Copycat Recipe)
Costco’s cilantro lime crema is one of those refrigerated section finds that quietly becomes a staple in your fridge. This copycat version takes about 10 minutes and uses ingredients you probably already have, so there’s no reason to wait until your next warehouse run.
It’s cool, tangy, and bright from the lime, with fresh cilantro running through every bite. Make a batch tonight and it’ll be ready before dinner is even on the table.
Why I Love This Recipe
This is the version I keep coming back to because the ratio of sour cream to mayonnaise keeps it rich without feeling heavy. The lime zest does a lot of quiet work here, adding a sharper citrus note than juice alone can manage.
It holds together beautifully as a drizzle, a dip, or a dollop, because the consistency lands right between a sauce and a spread.
Recipe Ingredients
- ½ cup sour cream – Full-fat gives the best body; light sour cream works but thins the texture slightly
- ¼ cup mayonnaise – Use a good-quality brand; it balances the tartness and adds richness
- ¼ cup fresh cilantro, loosely packed – Fresh only; dried cilantro will not give the same bright flavor
- 2 tbsp fresh lime juice – About 1 large lime; bottled lime juice is noticeably flatter here
- 1 tsp lime zest – Zest before juicing; this adds a sharper, more aromatic citrus layer
- 1 small garlic clove – Raw garlic gives a clean bite; use half a clove if you prefer something milder
- ¼ tsp kosher salt – Start here and adjust at the end after blending
- ¼ tsp ground cumin – Adds a subtle earthiness that rounds the brightness of the lime
- 1 tbsp water – Just enough to loosen the sauce to a drizzleable consistency
Variations / Substitutions
- Greek yogurt instead of sour cream – The crema stays tangy but gets a little thinner and slightly more tart, which works well if you want a lighter result.
- Avocado oil mayo instead of regular mayo – The flavor is cleaner and a bit more neutral, which lets the cilantro come forward more.
- Add 1 jalapeño (seeds removed) – Blending in half a seeded jalapeño adds a gentle heat without overwhelming the lime.
- Swap the garlic for ¼ tsp garlic powder – Garlic powder blends in more smoothly and gives a softer, less sharp background note.
- Dairy-free – Replace the sour cream with full-fat coconut cream and use a vegan mayo; the flavor shifts slightly tropical but still works well as a taco drizzle.
- Add more lime juice for extra acid – Up to 3 tbsp total if you want something noticeably more tart to cut through rich dishes.

How To Make Cilantro Lime Crema
Step 1: Blend the Herb Base
Add the ¼ cup fresh cilantro, 1 small garlic clove, 2 tbsp fresh lime juice, and 1 tsp lime zest to a small blender or food processor. Pulse 8 to 10 times until the cilantro is broken down into small flecks and the garlic is fully incorporated, about 20 seconds total.
You’re not looking for a smooth green paste yet. Small visible pieces of cilantro are fine at this stage, and the mixture will smell very sharp and herby, which is exactly right.
Step 2: Whisk in the Dairy
Add the ½ cup sour cream, ¼ cup mayonnaise, ¼ tsp kosher salt, and ¼ tsp ground cumin directly to the blender. Blend on low for 15 to 20 seconds, just until everything is combined and the color is a uniform pale green.
Don’t over-blend at this point. Running the blender too long at high speed can make the sour cream slightly gluey and over-aerate the mayo. A quick low-speed blitz is all you need.
Step 3: Adjust and Finish the Sauce
Add the 1 tbsp water and blend for another 5 seconds on low. Taste the crema and adjust salt or lime juice if needed, then blend one final time for 3 to 4 seconds to incorporate any additions.
The finished crema should fall off a spoon in a slow, ribbon-like stream. If it still feels too thick to drizzle, add water half a teaspoon at a time until it reaches the consistency you want.
Step 4: Pour and Garnish for Serving
Transfer the crema to a small serving bowl. Drizzle a few drops of fresh lime juice across the top, scatter a pinch of fresh cilantro leaves over the surface, and add a light dusting of cumin for color.
Recipe Tips
- Chill it for at least 30 minutes if you have the time. The flavors tighten up noticeably as it sits, and the garlic mellows from sharp to rounded.
- Zest the lime over the blender, not a cutting board. You lose less of the fragrant oil that way, and those oils are most of what the zest is contributing.
- The most common mistake is under-salting. Dairy mutes salt, so taste right after blending, then again after a minute. It often needs a small second pinch.
- Leftover crema is excellent as a salad dressing. Thin it with an extra teaspoon of water and a squeeze of lime and it pours beautifully over shredded cabbage.
This is a no-cook sauce, so a timing table doesn’t apply. Here’s how to scale the batch instead:
| Batch Size | Sour Cream | Mayonnaise | Cilantro | Lime Juice | Water |
|---|---|---|---|---|---|
| Half batch | ¼ cup | 2 tbsp | 2 tbsp | 1 tbsp | ½ tbsp |
| Standard (this recipe) | ½ cup | ¼ cup | ¼ cup | 2 tbsp | 1 tbsp |
| Double batch | 1 cup | ½ cup | ½ cup | 4 tbsp | 2 tbsp |
How To Store
- Refrigerate – Keep in an airtight jar or container for up to 5 days. Press a small piece of plastic wrap directly onto the surface before sealing to slow any browning from the lime.
- Serve Cold – This crema is meant to be served cold or at room temperature. It doesn’t need reheating and actually loses its fresh character if warmed.
What To Serve With Cilantro Lime Crema
Fish tacos are the most natural landing spot because the cool, tangy crema cuts right through the richness of fried or pan-seared fish. It also works well over a black bean and rice bowl, where the lime brightens up what can otherwise be a pretty flat, starchy base. Grilled corn on the cob is another strong pairing since the crema clings to the kernels and the cumin in the sauce echoes the char from the grill.
Frequently Asked Questions
Can I make this without a blender?
Yes. Mince the garlic and cilantro very finely by hand, then whisk everything together in a bowl. The texture will have more visible herb pieces, which some people actually prefer.
Can I freeze cilantro lime crema?
No. Sour cream and mayo both separate and turn grainy after freezing and thawing. Stick to refrigerator storage only.
How far ahead can I make this for a party?
Up to 2 days ahead is ideal. Beyond that it’s still safe to eat through day 5, but the lime flavor softens and the cilantro color can dull slightly.
Is this very garlicky?
With 1 small raw clove it has a noticeable but not aggressive garlic presence. If you’re serving guests who are sensitive to raw garlic, use just half a clove.
