Peruvian Chicken Sauce Recipe: Aji Amarillo Creamy Spice Blend

This Peruvian sauce transforms ordinary chicken into a restaurant-worthy dish with its creamy texture and vibrant flavor. The secret lies in aji amarillo peppers, which bring a unique fruity heat that defines this condiment.

Easy to prepare and versatile, this blend enhances grilled meats, roasted vegetables, or even as a dipping sauce. A small batch keeps well, so you can enjoy its bold taste anytime.

Ingredients for Peruvian Chicken Sauce

Nine ingredients blend into that signature creamy, fruity Peruvian sauce you’ll crave every time.

The aji amarillo peppers are non-negotiable here—they’re the soul of this sauce. Fresh peppers (found at Latin markets or online) give the brightest flavor, but jarred paste from Goya works in a pinch. I order mine from Melissa’s when I can’t find them locally. The mayo and sour cream combo creates that restaurant-quality creaminess, so don’t swap in low-fat versions (trust me, it’s worth the calories).

No aji amarillo paste? Habanero peppers at half the amount get you close to the heat level, though the fruity note won’t be the same. Out of sour cream? Full-fat Greek yogurt is a perfect sub. Fresh cilantro hater? Skip it or use parsley instead. The lime juice is key for brightness—bottled works, but fresh tastes noticeably better. Want it thicker? Reduce the onion slightly.

This keeps for up to 1 week in the fridge, stored in an airtight container. The flavors actually deepen after a day, so make it ahead if you can. Freezes beautifully for 3 months—portion into ice cube trays for easy serving. Always give it a good stir before using, as it separates a bit.

Step-by-Step Instructions for Peruvian Chicken Sauce

This creamy sauce comes together quickly with just a blender and a few fresh ingredients.

Step 1: Prepare the Fresh Ingredients

Start by finely chopping the 0.25 whole White Onion until you have about ¼ cup of small, even pieces. I like to dice it as fine as possible so it blends smoothly into the sauce without any chunky bits.

Peel and mince the 3 cloves Garlic Cloves until they’re almost paste-like. Remove the stems and seeds from the 1 whole Jalapeño Pepper (unless you want extra heat), then roughly chop it. Finally, measure out 0.25 cup Fresh Cilantro—just the leaves, no stems—as this will add that bright, fresh finish.

Step 2: Process the Aji Amarillo Peppers

If you’re using fresh 4 whole Aji Amarillo Peppers, remove the seeds and stems, then roughly chop them. For jarred paste, simply measure out the equivalent of 4 peppers (about ½ cup).

Add the prepared peppers to a blender or food processor. Pulse until they’re broken down into a coarse puree. You want some texture at this stage—it’ll smooth out completely once combined with the other ingredients. The color should be a vibrant yellow-orange, which is the signature of this Peruvian sauce.

Step 3: Blend All Ingredients Until Smooth

To the blender with the peppers, add the 0.75 cup Mayonnaise, 0.5 cup Sour Cream, minced garlic, chopped onion, jalapeño, and fresh cilantro. Pour in the 2 tbsp Lime Juice and add 0.5 tsp Salt and 0.25 tsp Black Pepper.

Blend everything on high for 30-45 seconds until completely smooth. Stop and scrape down the sides as needed. The sauce should be thick but pourable—if it seems too stiff, add a teaspoon of water and blend again. Taste and adjust the salt if needed; the flavors should be bright, creamy, and slightly tangy with a gentle kick from the peppers.

Step 4: Chill and Let Flavors Meld

Transfer the sauce to a clean jar or bowl and cover it tightly. Refrigerate for at least 30 minutes to let the flavors meld together. This resting time is key—it allows the garlic and lime to mellow slightly, creating a more balanced taste.

I like to give it a good stir before using, as the ingredients may separate slightly during chilling. The sauce will keep in the refrigerator for up to 5 days, and the flavors actually deepen over time. For the creamiest texture, serve it slightly cool rather than straight from the fridge.

Common Mistakes When Making peruvian chicken sauce

Skipping the Chill Time

I know it’s tempting to dive right in, but skipping the 30-minute resting period in the fridge means the flavors won’t fully meld. The garlic and lime need time to soften their sharpness, creating that balanced taste. Trust me, it’s worth the wait. 🌡️

Using Low-Fat Dairy

Swapping full-fat mayo or sour cream for low-fat versions will leave your sauce thin and lacking that signature creaminess. The fat is what gives it that rich, velvety texture. Stick to full-fat ingredients for the best results.

Overloading the Blender

Adding all ingredients at once can strain your blender and leave chunks behind. I blend the aji amarillo peppers first, then add the rest in stages. This ensures a smooth, lump-free consistency every time.

Ignoring the Pepper Seeds

Forgetting to remove the seeds from your jalapeño pepper or aji amarillo peppers can make the sauce uncomfortably spicy. Unless you want extra heat, always take a moment to seed them properly.

Skipping the Taste Test

Every pepper and lime varies, so always taste before serving. You might need an extra pinch of salt or a squeeze of lime juice to balance the flavors. I adjust mine every time.

Storing Improperly

Leaving the sauce in an uncovered container or at room temperature will shorten its life. Use an airtight container and refrigerate it promptly. It stays fresh for up to 5 days this way. ❄️
