Peruvian Ají Verde (Green Chili Sauce)

Description

Ají verde is one of Peru's most beloved sauces — vibrant green, herbaceous, creamy, and gently spicy. Centered on ají amarillo (Peru's signature yellow chili pepper), it blends roasted peppers with fresh cilantro, scallions, garlic, and lime, then thickens everything with mayonnaise and queso fresco. Use it as a marinade for pork lomo saltado, a dipping sauce for anticuchos (beef heart skewers), or a finishing drizzle on ceviche bowls.

Ingredients

• 6–8 whole ají amarillo peppers (or substitute 4–5 ripe yellow banana peppers plus 1 serrano pepper for heat)
• 1 large bunch fresh cilantro (about ¾ cup packed leaves and tender stems)
• 3 scallions, whites and greens separated; whites included here, reserved green tops for garnish
• 3 garlic cloves
• ½ cup mayonnaise (preferably a good-quality brand with mild flavor — it acts as an emulsifier more than a flavor driver here)
• 2 oz queso fresco or farmer's cheese, crumbled (about ¼ cup packed), optional but traditional for creaminess
• 3 tbsp fresh lime juice (about 1–1½ limes), plus more to taste
• 1 tsp ground cumin (optional — some households use it, others don't)
• ½ tsp kosher salt, plus more to taste

Instructions

1. Toast the peppers: Preheat a broiler to high or set out a comal/cast-iron skillet over medium heat. Place the ají amarillo peppers directly on the hot surface (or broiling rack), turning frequently with tongs. You want them blistered, charred, and soft all around — about 8–10 minutes total. They are done when you can easily squeeze them lightly and they yield like a ripe avocado.
2. Peel and clean: Transfer the charred peppers to a bowl and cover loosely with plastic for 3 minutes to steam (this loosens skins). Peel off the blackened skins, then slit each pepper open lengthwise. Slice in half crosswise, remove all seeds and white membrane with a spoon — this controls heat level significantly. Keep everything seed-free if you prefer moderate spice; leave some seeds for more fire.
3. Blend the sauce: Place the cleaned peppers, cilantro leaves and stems, scallion whites, garlic cloves, mayonnaise, queso fresco, lime juice, cumin (if using), and salt into a blender or food processor. Blend on high until completely smooth and bright green, about 45–60 seconds, stopping once to scrape down the sides.
4. Taste and adjust: The flavor should be herbal first, then creamy, with gentle heat blooming behind. Add more lime juice if it needs brightness, more salt for depth, or an extra serrano pepper blended in if you want a hotter kick. Consistency-wise, ají verde should pour slowly like a thick dressing — thin with 1 tbsp water if needed but not necessary.
5. Transfer to a serving bowl or squeeze bottle. The sauce works great immediately, but letting it rest at room temperature for 30–60 minutes allows the herbs and chili flavors to bloom further before serving.

Notes

• Ají amarillo substitutes: If you truly can't find ají amarillo fresh or jarred (it's widely available in Latin grocery stores), yellow banana peppers give the closest mild color and body, then add a serrano or jalapeño for that signature gentle heat. Some people use half habanero + half jalapeño if they have them — very close to authentic flavor when you can source them.
• Queso fresco matters: It adds creaminess and tang without overpowering the fresh herbs. Substitute crumbled feta in a pinch, but reduce salt slightly since feta is saltier. Vegan alternative: extra mayonnaise plus 1 tbsp nutritional yeast.
• Uses beyond dipping: Brush ají verde on pork loin or flank steak before grilling (it makes an incredible marinade), swirl it into pasta for a quick cream sauce without dairy, or dollop it over fried plantains (tostones) for contrast. Keeps refrigerated in an airtight container for up to 5–6 days — the color may darken slightly at room temp but flavor stays great.
• Heat control: Removing all seeds and inner white ribs from the peppers cuts most of the capsaicin. If you're feeding a crowd with different spice tolerances, make one batch without seeds (mild) and reserve pepper skins/seeds; blend them separately and offer a "hot version" on the side.
