Peruvian Green Sauce Aji Verde

My neighbor Luisa brought over a bottle of this green sauce at a backyard cookout three summers ago and I stood by the cooler spooning it onto everything from potato chips to grilled corn until she physically took the jar away from me.

I went home that night and blitzed together my first batch at midnight, overheating my blender and waking up my roommate, completely unrepentant.

Ingredients

• 1 cup fresh cilantro leaves, packed: This is the backbone so do not skimp and use the leaves mostly, stems are fine in small amounts.
• 2 green onions, roughly chopped: They add a milder onion bite that keeps the sauce from tasting flat.
• 1 to 2 fresh jalapeno or aji amarillo peppers, seeded and chopped: Aji amarillo is the authentic choice but jalapenos work beautifully and are easier to find.
• 2 cloves garlic, peeled: Raw garlic gives it a sharp kick so stick with two unless you are feeling brave.
• 1 tablespoon fresh lime juice: Brightens everything and cuts through the richness of the dairy.
• 1/3 cup mayonnaise: Creates the creamy base that carries all the flavors together.
• 1/4 cup sour cream or Greek yogurt: Adds tang and lightens the texture nicely.
• 2 tablespoons grated Parmesan cheese: A salty umami boost that most people never expect in a green sauce.
• 2 tablespoons olive oil: Helps the blender run smoothly and adds body.
• 1 teaspoon white vinegar: An extra layer of acidity that makes the flavors pop.
• 1/4 teaspoon kosher salt and 1/4 teaspoon black pepper: Season to taste at the end because the cheese adds salt too.

Instructions

Load the blender:

Toss in the cilantro, green onions, peppers, and garlic first so the blades catch everything evenly.

Add the creamy ingredients:

Pour in the lime juice, mayonnaise, sour cream, Parmesan, olive oil, vinegar, salt, and pepper right on top.

Blend until silky:

Run on high for about a minute, stopping once to scrape down the sides, until you see a vivid green smooth sauce.

Taste and adjust:

Sample it and add more salt or another pepper if you want it fiercer, then blend again briefly.

Chill if you can wait:

Transfer to a bowl and let it rest in the fridge for thirty minutes so the flavors settle into something magical.

I once caught my friend David eating this sauce with a spoon straight from the container and he looked at me and said he was not sorry.

How to Serve It

Drizzle it over roasted chicken thighs, swipe it onto sandwiches, or use it as a dip for sweet potato fries and it will never be the wrong answer.

Swaps and Adjustments

Use all Greek yogurt instead of sour cream for a lighter version or leave out the cheese entirely if dairy is an issue.

Storing Leftovers

Keep it in an airtight jar in the fridge for up to five days and stir before serving since it may separate slightly.

• A mason jar with a tight lid works better than a bowl covered with plastic wrap.
• The color will darken a bit overnight but a quick stir brings back the bright green.
• Do not freeze it because the texture breaks when it thaws.

Pin It

Make a double batch because sharing one jar is harder than you think and you will want your own.

Recipe Questions & Answers

→ What makes aji verde sauce authentic?

Authentic Peruvian aji verde traditionally uses aji amarillo peppers, which provide a distinctive fruity heat. When unavailable, jalapeños make an excellent substitute. The combination of fresh herbs, creamy dairy elements, and acidic lime juice creates the characteristic flavor profile that defines this beloved Peruvian condiment.

→ Can I make this sauce dairy-free?

Yes, simply substitute the mayonnaise with a vegan alternative, use dairy-free yogurt or coconut yogurt instead of sour cream, and omit the Parmesan cheese. The sauce will still be creamy and flavorful, with the herbs and peppers providing the signature taste.

→ How spicy is this green sauce?

The heat level is moderate and adjustable. Removing all seeds from the jalapeños yields a milder sauce, while keeping some seeds or adding an extra pepper increases the spiciness. Aji amarillo peppers tend to be slightly fruitier and less fiery than jalapeños, offering a more nuanced heat.

→ How long can I store this sauce?

Store in an airtight container in the refrigerator for up to one week. The flavors actually improve after sitting for a few hours, so making it ahead of time is recommended. The sauce may thicken slightly when chilled—thin with a little water or olive oil if needed.

→ What dishes pair well with aji verde?

This versatile sauce excels with roasted or rotisserie chicken, grilled steak, pork, or fish. It's also delicious drizzled over roasted vegetables, potatoes, or sweet potatoes. Use it as a dip for fries, quesadillas, or empanadas. Its bright acidity and herbal notes complement rich, savory dishes perfectly.

→ Can I freeze this sauce?

While possible, freezing may affect the creamy texture and cause separation. The sauce is quick enough to prepare fresh that freezing isn't usually necessary. If you must freeze it, expect to re-blend or whisk vigorously after thawing to restore consistency.
