Peruvian Green Sauce Aji Verde

The blender screamed when I dumped a whole cup of cilantro stems and all into it, and my roommate came running thinking something had gone terribly wrong in the kitchen. That was a Tuesday night in my tiny apartment, and I was attempting to recreate the impossibly green sauce from a Peruvian rotisserie spot that had recently stolen my lunch budget. The smell hit me before the taste, bright and sharp and alive, and I knew right then this sauce was going to be a permanent fixture in my fridge.

I brought a jar of this to a backyard cookout last summer and watched three grown adults fight over the last spoonful, wiping it onto tortilla chips like it was the main event. One friend literally licked the jar lid and nobody judged her.

Ingredients

• Fresh cilantro leaves, 1 cup packed: Do not skimp on this, pack it down like you mean it, and do not bother stripping every leaf from the stems because the stems add flavor and the blender does the work.
• Green jalapeño peppers, 2 to 3 stemmed and seeded: Seeding tames the heat enough for most people, but if you like it fiery, leave some seeds in and brace yourself.
• Garlic cloves, 2: Raw garlic is the backbone here, so use fresh cloves, not the jarred kind sitting in water.
• Green onions, 2 roughly chopped: These add a mild onion sweetness that regular onions would overpower.
• Fresh lime juice, 1 tablespoon: Squeeze it fresh, the bottled stuff tastes flat and this sauce deserves brightness.
• Mayonnaise, 1 tablespoon: Just a spoonful for body and richness, it is not the star but it holds everything together.
• Greek yogurt or sour cream, 2 tablespoons: This is where the creaminess comes from, and Greek yogurt adds a pleasant tang.
• Grated parmesan cheese, 2 tablespoons: A trick I learned from a Peruvian cook who said the cheese deepens the flavor without making it taste Italian.
• Dijon or yellow mustard, 1 teaspoon: A tiny amount that most people cannot identify but would miss if it were gone.
• Olive oil, 1 tablespoon: Helps the sauce blend silky smooth.
• Kosher salt, 1/2 teaspoon: Start here and adjust later after tasting.
• Black pepper, 1/4 teaspoon: Freshly cracked if you have it.

Instructions

Load the greens:

Toss the cilantro, jalapeños, garlic, and green onions into your blender or food processor and let the machine tear through them until you see bright green chunks bouncing around.

Add the creamy crew:

Pour in the lime juice, mayo, yogurt, parmesan, mustard, olive oil, salt, and pepper, then watch everything transform from a chunky mess into something uniformly vibrant.

Blend until silky:

Run the blender on high, stop to scrape down the sides once or twice, and keep going until not a single fleck of green remains chunky.

Taste and tweak:

Stick a spoon in, taste it, and trust your instincts because this is where you decide if it needs more salt, more lime, or more heat.

Serve or stash:

Scoop it into a bowl and drizzle it over everything in sight, or seal it in a jar and tuck it into the fridge where it will keep beautifully for up to three days.

Save

There is something about a bright green sauce sitting on the table that makes everyone curious, and watching people dip cautiously and then go back for a third scoop never gets old.

What to Serve It With

Spoon it over grilled chicken thighs, roasted potatoes fresh from the oven, or a plain bowl of white rice that needs a reason to exist. I have also been known to spread it on turkey sandwiches and dip raw carrots straight into the jar while standing at the open fridge.

Making It Vegan

Swap the mayo for a good vegan alternative, replace the yogurt with a dairy free version, and either skip the parmesan or use a nutritional yeast based substitute. The sauce loses none of its personality and honestly most people cannot tell the difference.

Storage and Leftovers

Keep it in a sealed container in the refrigerator and stir it before using because settling is natural. The color may darken slightly by day three but the flavor holds up.

• A film of olive oil on top helps preserve the bright green color overnight.
• Do not freeze it because the dairy separates and the texture never recovers.
• Always make a double batch because one cup disappears faster than you expect.

Save

Keep a jar of this in your fridge and you will never have a boring meal again. It is the kind of recipe that makes you wonder how you ever ate without it.

Stored in an airtight container, the sauce keeps well for up to 3 days in the refrigerator. The flavors may even develop and meld together better after a day of chilling.

→ Can I freeze this green sauce?

While you can freeze it, the creamy texture may change slightly upon thawing. For best results, make fresh batches and refrigerate. If freezing, expect some separation that can be blended again after thawing.
