Hello, fellow food lovers! Chef Andrew here.

Let’s be honest. We’ve all been stuck in a chicken rut. You buy it, you cook it, you eat it… and then you forget it. It’s nourishing, sure, but is it memorable? Is it the kind of meal that has your family and friends asking, “Wow, what is in this?”

For years, I’ve been chasing the ghost of the perfect roasted chicken I had at a tiny little restaurant in Lima. It had unbelievably crispy skin, impossibly juicy meat, and a vibrant, spicy, creamy green sauce that I could have eaten with a spoon. Today, we’re not just going to replicate that meal. We’re going to master it.

So, what’s the #1 secret? It’s not one single ingredient. The secret is a three-part harmony: a potent, flavor-packed marinade that works its magic deep in the meat; a specific grilling technique that guarantees crispy skin and juicy flesh; and the most addictively creamy green sauce you’ll ever make.

Ingredients

  

For the Aji Verde (Creamy Green Sauce)

• 3 whole jalapeño chiles roughly chopped, remove seeds for less heat
• 1 tbsp ají amarillo pepper paste highly recommended
• 1 cup fresh cilantro leaves packed
• 2 medium cloves garlic
• 1/2 cup good-quality mayonnaise
• 1/4 cup sour cream
• 2 tsp fresh lime juice
• 1 tsp distilled white vinegar
• 2 tbsp extra-virgin olive oil
• Kosher salt and freshly ground black pepper to taste

For the Peruvian Grilled Chicken

• 1 whole chicken about 3.5 to 4 pounds
• 4 tsp kosher salt
• 2 tbsp ground cumin
• 2 tbsp paprika sweet, not smoked
• 1 tsp freshly ground black pepper
• 3 medium cloves garlic minced
• 2 tbsp white vinegar
• 2 tbsp vegetable or canola oil

Instructions

 

• Step 1: Make the Creamy Green SauceCombine the jalapeños, ají amarillo paste, cilantro, garlic, mayonnaise, sour cream, lime juice, and vinegar in your blender. Blend on high speed until completely smooth. With the blender running on low, slowly drizzle in the olive oil to emulsify. Season generously with salt and pepper. Transfer to an airtight container and refrigerate for at least 30 minutes to thicken.
• Step 2: Prepare the ChickenSpatchcock the chicken: place it breast-side down and use kitchen shears to cut out the backbone. Flip the chicken over and press firmly on the breastbone to flatten it. Pat the entire chicken completely dry with paper towels.
• Step 3: Marinate the ChickenIn a small bowl, mix salt, cumin, paprika, pepper, minced garlic, vinegar, and oil into a paste. Rub about a third of the marinade under the skin of the breasts and thighs. Rub the remaining marinade all over the outside.
• Step 4: Grill the Chicken to PerfectionSet up a two-zone grill (one hot side, one cool side). Place the chicken skin-side up on the cooler side and cook, covered, until an instant-read thermometer in the breast registers 110°F (43°C).
• Step 5: Crisp the SkinMove the chicken skin-side down to the hotter side of the grill. Cover and cook until the skin is deep golden brown and crisp, and the breast temperature reaches 145-150°F (63-66°C). Watch closely to prevent burning.
• Step 6: Rest and ServeTransfer the chicken to a cutting board and let it rest for 10 minutes. Carve and serve immediately with the chilled creamy green sauce.

Notes

Chef Andrew’s Pro-Tips

• Don’t Skip the Rest: Resting the chicken is just as important as cooking it to keep it juicy.
• Thermometer is King: Cooking to temperature, not time, is the only way to guarantee perfectly cooked chicken.
• Serving Suggestions: This dish is traditionally served with thick-cut French fries and a simple salad. It’s also fantastic with roasted potatoes or rice.

Why This Recipe is Truly Unforgettable

Most recipes give you a list of instructions. I want to give you the understanding behind them. This isn’t just about mixing and grilling; it’s about creating layers of flavor.

1. The Marinade is a Flavor Bomb: We’re using a powerful combination of earthy cumin, smoky paprika, pungent garlic, and sharp vinegar. This isn’t just a surface-level rub; it’s a marinade that tenderizes the meat while infusing it with classic Peruvian flavor.
2. The Grill Technique is a Game-Changer: Forget just throwing the chicken on the fire. We’ll be using a two-zone grilling method. This is the professional’s technique for perfectly cooked poultry. It allows us to gently cook the chicken through with indirect heat before crisping the skin to a beautiful, crackling finish over direct heat. No more burnt skin and undercooked meat!
3. The Sauce is Liquid Gold: This isn’t just any sauce. This is Aji Verde—a vibrant blend of jalapeño, cilantro, garlic, and a touch of ají amarillo paste. It’s spicy, herbaceous, tangy, and creamy all at once. It’s the perfect, cooling counterpoint to the smoky, savory chicken. Making an incredible creamy green sauce is half the battle.

Part 1: The Soul of the Dish – The Marinade

The foundation of our Peruvian grilled chicken is this simple but potent marinade. Each ingredient plays a crucial role.

• Cumin & Paprika: These form the earthy, smoky backbone of the flavor profile. Don’t be shy with them!
• Garlic: Provides a pungent, aromatic kick that permeates the meat.
• White Vinegar: This is key! The acid not only adds a tangy brightness but also helps to tenderize the chicken, allowing the flavors to penetrate more deeply.
• Oil: This acts as a binder, helping the spices and aromatics cling to every part of the chicken.

When you massage this mixture into the chicken, you’re not just seasoning it; you’re starting a chemical reaction that will result in a more flavorful, tender bird.

Part 2: Mastering the Grill – Spatchcock & Two-Zone Fire

If the word “spatchcock” intimidates you, don’t let it! It’s simply the process of removing the backbone so the chicken can lie flat.

Why do we do this?
A flat chicken cooks dramatically more evenly than a whole, round one. The legs and breasts finish cooking at roughly the same time. It also exposes more skin, leading to a crispier result. This is a non-negotiable step for a truly great Peruvian grilled chicken.

The Two-Zone Fire:
This is your best friend for grilling. You’ll have one side of the grill with hot coals (or high-heat gas burners) and one side with no coals (or turned-off burners).

• The Cool Zone: We start the chicken here, skin-side up. This allows the chicken to cook through gently with indirect heat, like an oven. The internal temperature will rise without the skin burning.
• The Hot Zone: We finish the chicken here, skin-side down. This is a quick, high-heat step designed to do one thing: get that skin incredibly crispy.

Part 3: The Crown Jewel – That Creamy Green Sauce (Aji Verde)

I cannot overstate this: this sauce will change your life. It’s the perfect companion for your Peruvian grilled chicken, but you’ll soon find yourself putting it on tacos, salads, fish, and French fries.

The key to a balanced creamy green sauce is hitting all the right notes:

• Spice (Jalapeños): We use whole jalapeños for a good kick. If you’re shy about heat, remove the seeds and ribs first.
• Authenticity (Ají Amarillo Paste): This Peruvian yellow pepper paste adds a unique, fruity heat. You can find it in Latin markets or online, and it’s worth seeking out!
• Freshness (Cilantro & Lime): These provide the bright, herbaceous, and tangy lift that cuts through the richness.
• Creaminess (Mayonnaise & Sour Cream): This is what gives the sauce its luscious body and cools down the heat just enough.

Now, let’s bring it all together.

The #1 Secret to Unforgettable Peruvian Grilled Chicken & Creamy Green Sauce

This recipe delivers a restaurant-quality meal at home. The secret is in the synergy of the marinade, the precise grilling technique, and the vibrant sauce.

Yields: 4 servings
Prep time: 20 minutes
Cook time: 45 minutes

Ingredients

For the Aji Verde (Creamy Green Sauce):

• 3 whole jalapeño chiles, roughly chopped (remove seeds for less heat)
• 1 tablespoon (15 ml) ají amarillo pepper paste (highly recommended, but optional)
• 1 cup fresh cilantro leaves (packed)
• 2 medium cloves garlic
• 1/2 cup (120 ml) good-quality mayonnaise
• 1/4 cup (60 ml) sour cream
• 2 teaspoons (10 ml) fresh lime juice
• 1 teaspoon (5 ml) distilled white vinegar
• 2 tablespoons (30 ml) extra-virgin olive oil
• Kosher salt and freshly ground black pepper to taste

For the Peruvian Grilled Chicken:

• 1 whole chicken (about 3.5 to 4 pounds)
• 4 teaspoons kosher salt
• 2 tablespoons ground cumin
• 2 tablespoons paprika (sweet, not smoked)
• 1 teaspoon freshly ground black pepper
• 3 medium cloves garlic, minced
• 2 tablespoons white vinegar
• 2 tablespoons vegetable or canola oil

Special Equipment

• Grill (charcoal or gas)
• Blender
• Instant-read thermometer (this is essential!)
• Kitchen shears

Instructions

Step 1: Make the Creamy Green Sauce

1. Combine the jalapeños, ají amarillo paste, cilantro, garlic, mayonnaise, sour cream, lime juice, and vinegar in your blender.
2. Blend on high speed until the mixture is completely smooth. You may need to scrape down the sides once or twice.
3. With the blender running on low, slowly drizzle in the olive oil. This emulsifies the sauce, making it extra creamy.
4. Season generously with salt and pepper to taste. The sauce will seem a little loose at first—don’t worry! It will thicken up perfectly in the fridge. Transfer to an airtight container and refrigerate for at least 30 minutes.

Step 2: Prepare the Chicken

1. Spatchcock the Chicken: Place the chicken on a cutting board, breast-side down. Using sturdy kitchen shears, cut along both sides of the backbone from the tail to the neck. Remove the backbone (save it for stock!).
2. Flip the chicken over. Using the heel of your hand, press down firmly on the center of the breastbone until you hear a crack. The chicken should now lie flat.
3. Pat the entire chicken, especially the skin, completely dry with paper towels. This is a critical step for crispy skin.

Step 3: Marinate the Chicken

1. In a small bowl, combine the salt, cumin, paprika, black pepper, minced garlic, vinegar, and oil. Mix with your fingers until it forms a uniform, thick paste.
2. Gently loosen the skin over the breasts and thighs. Rub about one-third of the marinade directly onto the meat under the skin.
3. Rub the remaining marinade all over the outside of the chicken, covering every surface. Let it sit for at least 15 minutes at room temperature, or ideally, refrigerate for 4 to 6 hours for maximum flavor.

Step 4: Grill the Chicken to Perfection

1. Set Up a Two-Zone Grill:
   • Charcoal: Light a chimney of charcoal. Once lit, pour the coals over one half of the grill grate, leaving the other half empty.
   • Gas: Set half of your burners to high heat and leave the other half off.
2. Place the cooking grate on, cover the grill, and preheat for 5 minutes. Clean and oil the grates.
3. Indirect Cooking: Place the chicken skin-side up on the cooler side of the grill, with the legs pointing toward the hot side (as they take longer to cook). Cover the grill.
4. Cook until an instant-read thermometer inserted into the thickest part of the breast registers 110°F (43°C), about 25-30 minutes.
5. Direct Searing for Crispy Skin: Carefully flip the chicken and move it to the hotter side of the grill, skin-side down. Press down with a spatula for good contact.
6. Cover and cook, checking frequently, until the skin is deep golden brown and crisp, and the breast temperature reaches 145-150°F (63-66°C). This will take about 8-12 minutes. Be vigilant here to prevent burning!

Step 5: Rest and Serve

1. Transfer the chicken to a clean cutting board and let it rest for 10 minutes. This allows the juices to redistribute for a moister bird.
2. Carve the rested Peruvian grilled chicken and serve immediately with generous amounts of the chilled creamy green sauce.

Chef Andrew’s Pro-Tips & Serving Suggestions

• Don’t Skip the Rest: Resting the chicken is just as important as cooking it. Cutting into it too early will result in a dry bird and a puddle of lost juices.
• Thermometer is King: Cooking to temperature, not time, is the only way to guarantee perfectly cooked chicken.
• Serving: This dish is traditionally served with thick-cut French fries and a simple lettuce and tomato salad. It’s also fantastic with roasted potatoes or rice.

Enjoy the process, and get ready for the compliments to roll in!
