Peruvian Chicken White Sauce Recipe: Authentic Aji Verde Creaminess

This Peruvian white sauce captures the authentic essence of aji verde with its creamy, herbaceous profile. I’ve refined this condiment to balance fresh jalapeños, cilantro, and tangy lime juice perfectly.

The result is a smooth, vibrant sauce that elevates grilled chicken or fish. It stays fresh for days and delivers that restaurant-quality touch to any meal.

Ingredients for Peruvian Chicken White Sauce

Nine ingredients for that authentic Peruvian creaminess you’ve been craving.

The cilantro and jalapeños are non-negotiable here—fresh is everything. Look for cilantro with bright green leaves and no wilting. Jalapeños should be firm, not soft. Latin markets often have the best selection, but regular grocery stores work fine too. The mayo and sour cream need to be full-fat (the light stuff just won’t give you that restaurant-quality texture). Duke’s or Hellmann’s are my go-to mayo brands.

No queso fresco? Cotija cheese is the closest substitute—it’s saltier, so go light at first. Fresh out of lime juice? Bottled works in a pinch, but fresh is worth the squeeze. If you want a lighter version, Greek yogurt instead of sour cream keeps it creamy without the guilt. The garlic can be adjusted to taste—add an extra clove if you love that punch.

This sauce keeps beautifully. Store it in an airtight container in the fridge for up to 5 days—the flavors actually deepen over time. For longer storage, freeze in ice cube trays for up to 3 months. Thaw in the fridge overnight before using.

Step-by-Step Instructions for Peruvian Chicken White Sauce

Here’s the method. Straightforward, tested, works every time.

Step 1: Prep and Blanch the Aromatics

Remove stems from the 2 cups Fresh Cilantro and roughly chop the leaves and tender stems. For the 2 whole Jalapeño Peppers, slice in half lengthwise, remove seeds and ribs, then rough chop. Peel the 4 cloves Garlic Cloves and chop roughly as well.

Bring a small pot of water to a boil and blanch the jalapeños and garlic for 2 minutes. This mellows the heat while preserving the bright flavor. Drain immediately and plunge into ice water to stop the cooking process. Drain again and pat dry with paper towels.

Step 2: Blend the Base Ingredients

In a blender or food processor, combine the blanched jalapeños, garlic, and 2 cups Fresh Cilantro. Pulse until finely chopped but not pureed—you want some texture. Scrape down the sides as needed to ensure everything gets incorporated evenly.

With the blender running, drizzle in the 2 tbsp Extra-Virgin Olive Oil and the 3 tbsp Fresh Lime Juice. Blend for another 30 seconds until the mixture is smooth but still has some body. The oil helps emulsify the sauce, while the lime juice adds the signature brightness.

Step 3: Incorporate the Creamy Elements

Add the 1 cup Mayonnaise, 0.5 cup Sour Cream, and 0.5 tsp Salt to the blender. Pulse a few times until just combined—over-blending can make the sauce too thin. The mayonnaise provides a rich, velvety base, while the sour cream adds tang and depth.

Taste and adjust the seasoning if needed. If the sauce is too thick, you can thin it with a splash of water or lime juice. Transfer the mixture to a bowl and fold in the 0.5 cup Crumbled Queso Fresco by hand. This keeps the cheese in visible flecks for texture and visual appeal.

Step 4: Chill and Let Flavors Meld

Cover the bowl and refrigerate for at least 30 minutes (or up to 24 hours). Chilling allows the flavors to meld together and the sauce to thicken slightly. The queso fresco will soften and distribute its salty, milky flavor throughout the sauce.

Give it a good stir before serving. The sauce should be creamy, tangy, and slightly herby with a subtle kick from the jalapeños. It’s perfect for drizzling over grilled chicken, fries, or even as a dip for crusty bread.

Serving Suggestions for This Recipe

As a Dip

This sauce shines as a dip for crusty bread or tortilla chips. I serve it in a small bowl with a drizzle of olive oil on top. The creamy texture clings perfectly to every bite. 💛

With Grilled Proteins

The classic pairing is with grilled chicken, but it works wonderfully with shrimp skewers or fish tacos. Brush it on during the last minute of grilling for a flavor boost, or serve it on the side for dipping.

On Sandwiches

Spread this on ciabatta rolls or baguettes before adding your proteins. It adds moisture and a bright, herby kick. I love it with leftover rotisserie chicken and avocado slices.

For Salad Dressing

Thin it with a little water or lime juice to create a creamy salad dressing. It pairs especially well with romaine lettuce, black beans, and corn for a South American-inspired salad.

With Vegetables

Drizzle over roasted or grilled veggies like asparagus, zucchini, or cauliflower. The sauce’s tanginess complements the smoky char from the grill beautifully. 🔥

As a Taco Topping

Spoon this over fish tacos or chicken tacos instead of the usual salsa. The creamy texture and fresh flavors elevate the dish to restaurant-quality. I always add a sprinkle of queso fresco on top for extra authenticity.
