A vibrant herb paste marinade inspired by Peruvian cuisine, combining the distinctive anise-like flavor of huacatay with bright lime juice, aromatic garlic, warm cumin, and a hint of aji amarillo's fruity heat.

Steps

Before you start

Pat chicken breasts dry before marinating so they absorb flavors better
If using fresh huacatay, remove tough stems and use only tender leaves and thin stems
Have lime juice freshly squeezed if possible—bottled juice lacks the brightness this marinade needs

1
Prep the huacatay and garlic
- On a cutting board, roughly chop the fresh huacatay leaves (removing any tough stems as you go).
- Chop the peeled garlic cloves into smaller pieces.
- This rough prep makes processing easier and helps release the aromatic oils.

Ready when: Huacatay and garlic are roughly chopped into ¼-inch (6 mm) pieces
Tip: Chop huacatay just before processing so it doesn't oxidize and lose its bright green color and fresh aroma.
2
Make the herb paste
- Combine the chopped huacatay, garlic, aji amarillo paste, and ground cumin in a small food processor (or mortar and pestle).
- Pulse until the mixture becomes a coarse, fragrant paste, about 1–2 minutes.
- The garlic and huacatay should be finely minced but retain some texture—do not overprocess into a completely smooth purée.

Ready when: Mixture is coarse and fragrant with visible herb flecks and no large chunks of garlic
Tip: If processing by hand, mince the garlic first, then add huacatay and smash together with a pinch of salt to help break down the leaves.
3
Build the marinade
- Transfer the herb paste to a medium bowl.
- Whisk in lime juice, olive oil, kosher salt, and black pepper until well combined.
- The marinade should be cohesive with a loose paste consistency—not too thin or runny.
- Taste and adjust salt or lime juice if needed to balance the herbaceous flavor with citrus brightness and gentle heat.

Ready when: Marinade is well blended with no streaks of oil and uniform pale green color
Tip: Reserve 2 tablespoons of the marinade in a separate container if you plan to use it as a finishing sauce on cooked chicken—this keeps it food-safe since it won't have contacted raw poultry.
4
Coat and marinate the chicken
- Place the 4 patted-dry chicken breasts in a zip-top plastic bag or shallow dish.
- Pour the entire marinade over the chicken, turning each breast to coat evenly on all sides.
- Use your hands to press the paste gently into the meat so it adheres well, paying special attention to the thicker sections.
- Seal the bag or cover the dish tightly with plastic wrap.
- Refrigerate for at least 30 minutes to allow the huacatay, lime, and spices to penetrate.
- For deeper, more complex Peruvian flavors, marinate up to 12 hours, turning the chicken halfway through if marinating longer than 2 hours.

Ready when: Chicken is thoroughly coated with green herb paste, and a fragrant herbaceous and citrus aroma is noticeable when the container is opened
Tip: If marinating longer than 2 hours, flip the chicken halfway through to ensure even flavor distribution, especially in thick sections near the center.

Tips

Huacatay is the soul of this marinade—source it from a Latin market or specialty grocer if possible; fresh herbs make a brighter, more authentic result than dried
For a more intense marinade, add 1 tablespoon of red wine vinegar or additional lime juice to the paste, then reduce the olive oil slightly to maintain balance
After cooking, brush the warm chicken with a small amount of reserved fresh marinade (made separately, not the raw poultry version) or a quick chimichurri-style drizzle of fresh cilantro, lime, and olive oil for an extra flavor boost
This marinade works equally well on grilled chicken, pan-seared breasts, or oven-roasted chicken at 400°F (200°C) for 20–24 minutes—adjust cooking time based on thickness and your chosen method

Make ahead

Make the marinade up to 2 days ahead; store in an airtight container in the refrigerator. Marinate chicken up to 12 hours ahead for maximum flavor development.

Storage & reheating

Unused marinade keeps in a sealed container in the refrigerator for up to 3 days. Once raw chicken has been marinated, do not reuse the marinade unless it has been boiled for at least 1 minute first. Marinated chicken will keep refrigerated for up to 2 days before cooking. Reserved cooked-chicken finishing sauce (made with fresh herbs, not raw-chicken marinade) keeps refrigerated for up to 1 day.

Substitutions

fresh huacatay leaves, loosely packed → ½ cup (12 g) fresh cilantro plus 1 tablespoon fresh mint leaves. Cilantro and mint capture huacatay's bright, herbaceous quality with a slight anise undertone, though the result will be less distinctly Peruvian.
aji amarillo paste → ½ teaspoon smoked paprika mixed with ½ teaspoon hot paprika. Paprika won't replicate aji amarillo's fruity heat exactly, but provides warmth and subtle smokiness. Start with less and taste before adding more.
fresh lime juice → 3 tablespoons fresh lemon juice plus 1 tablespoon white vinegar. Lemon is less sharp than lime; the vinegar bridges the gap and maintains the acidic balance needed to tenderize the chicken.
boneless, skinless chicken breasts → 1.5 lbs (680 g) boneless, skinless chicken thighs or 2 lbs (900 g) bone-in, skin-on chicken thighs. Thighs are more forgiving and juicier than breasts. Increase marinating time by 10–15 minutes and adjust cooking time as thighs take longer to cook through.
