Huacatay Sauce Recipe: Peruvian Herb-Infused Creamy Delight

This Peruvian sauce transforms any dish with its creamy, herbaceous depth. The black mint leaves deliver a unique flavor that’s earthy with a subtle citrus note.

I developed this version to pair perfectly with grilled meats and potatoes. It keeps for 5 days in the fridge, making it a versatile addition to your culinary repertoire.

Ingredients for Huacatay Sauce

Ten ingredients come together for this creamy, herb-packed Peruvian sauce with earthy depth.

Huacatay is the star here—look for it at Latin markets or online (it’s also called black mint). Fresh is non-negotiable; dried loses that vibrant, citrusy punch. The cilantro and mint should be bright green, not wilted. Whole Foods often has fresh huacatay in their herb section. If you’re struggling to find it, ask for Peruvian black mint. Garlic and jalapeño add the backbone, so don’t skimp on freshness.

No huacatay? Double the mint and cilantro plus a pinch of dried mint won’t be the same but gets you close. For heat, serrano peppers work instead of jalapeño (they’re hotter, so use half). Vegan mayo is key—Hellmann’s Vegan or Just Mayo blend smoothly. Out of lime juice? Lemon juice at the same amount works, but lime’s brightness is ideal. Olive oil can be swapped for avocado oil if that’s what you’ve got.

This sauce keeps 5 days in the fridge in an airtight container. The flavors deepen overnight, so make it ahead if you can. Freeze in ice cube trays for up to 3 months—perfect for adding to soups or marinades later. Always give it a stir before using, as the herbs settle.

Step-by-Step Instructions for Huacatay Sauce

This method delivers a vibrant, creamy herb sauce that highlights the unique black mint flavor of huacatay.

Step 1: Prepare and Blanch the Herbs

First, I remove all stems from the 1 cup Huacatay Leaves, 0.5 cup Fresh Cilantro, and 0.25 cup Fresh Mint Leaves. This step ensures a smooth texture in the final sauce without fibrous bits. Rinse them thoroughly under cold water to remove any grit.

Bring a small pot of water to a boil. I blanch the herb leaves for 30 seconds to soften them and remove any bitterness. Immediately shock them in ice water to preserve their bright green color and fresh flavor. Drain well and gently squeeze out excess water with your hands.

Step 2: Process the Aromatics

In a food processor, combine the blanched herbs with the 4 cloves Garlic Cloves and 1 whole Jalapeño Pepper. Pulse until finely chopped, scraping down the sides as needed. The mixture should look like a coarse green paste with no large pieces remaining.

Here’s the thing—you want to process these first to break down the fibrous herbs before adding the liquids. This creates a more uniform texture in your sauce. The jalapeño adds just enough heat to balance the herbal notes without overpowering them.

Step 3: Emulsify with Fats and Acids

Add the 0.75 cup Vegan Mayonnaise and 0.25 cup Extra-Virgin Olive Oil to the herb mixture. Process continuously for 1-2 minutes until completely smooth. The sauce will thicken and become creamy as the oils emulsify with the herb purée.

Pour in the 2 tbsp Lime Juice while the processor is running. The acid brightens all the flavors and helps preserve the vibrant green color. Stop and scrape down the sides once or twice to ensure everything is fully incorporated.

Step 4: Season and Adjust Consistency

Transfer the sauce to a bowl and stir in the 0.5 tsp Salt and 0.25 tsp Black Pepper. Taste and adjust the seasoning if needed—I sometimes add a pinch more salt if the herbs were particularly mild.

If the sauce is too thick, thin it with a tablespoon or two of cold water until it reaches your desired consistency. For serving as a dip, I like it slightly thicker. For drizzling over dishes, a looser consistency works better. The sauce should be smooth, creamy, and vibrant green with specks of herbs visible.

Let it rest for 10 minutes before serving to allow the flavors to meld together. The sauce will keep in the refrigerator for up to 5 days in an airtight container.

Dietary Considerations for This huacatay sauce

Vegan and Dairy-Free

This sauce is naturally 100% plant-based, thanks to the vegan mayonnaise base. I use Hellmann’s Vegan or Just Mayo for the creamiest texture. No dairy means it’s perfect for vegan diets or anyone with lactose intolerance. 💪

Gluten-Free Friendly

All ingredients in this recipe are inherently gluten-free. Just verify your vegan mayo brand is certified gluten-free—most are, including the ones I mentioned. No risk of cross-contamination here, making it safe for celiac disease or gluten sensitivity.

Nut-Free Option

While the base recipe is nut-free, some vegan mayos contain almond or cashew ingredients. For nut allergies, stick with soy-based vegan mayo brands like Hellmann’s Vegan. Always check labels to be absolutely certain.

Low-Carb and Keto

With only 2g net carbs per 2-tbsp serving (mostly from herbs and lime), this fits perfectly into low-carb and keto diets. The fat from olive oil and mayo provides that satisfying richness keto followers crave.

Allium Sensitivity

For those avoiding garlic, simply omit the 4 cloves and add ½ tsp asafoetida powder (hing) for a similar depth. The jalapeño can also be reduced or omitted if nightshades are an issue.

Sodium Control

To reduce sodium, use low-sodium vegan mayo and cut the salt to ¼ tsp. The herbs provide plenty of flavor, so you won’t miss the extra salt. 🌱
