Peruvian-Style Roast Chicken with Creamy Green Sauce

Peruvian-style roast chicken takes its cues from pollo a la brasa, pairing garlic, cumin, lime, and soy with juicy roasted chicken and a bright cilantro green sauce. Regional and family versions vary, but this practical home version brings together savory, citrusy chicken and a tangy, gently spicy sauce for spooning over every slice.

Ingredients

1 whole chicken, about 4 lb (1.8 kg), giblets removed
2 tsp fine salt (12 g)
½ tsp freshly ground black pepper (1 g)
5 garlic cloves, finely grated or minced (about 15 g)
2 tbsp fresh lime juice (30 ml)
2 tbsp soy sauce (30 ml)
1 tbsp neutral oil, such as canola (15 ml)
1½ tsp ground cumin (3 g)
1 tsp sweet paprika (2 g)
1 tsp dried oregano (1 g)
½ tsp finely grated lime zest (about 1 g)
1 packed cup fresh cilantro leaves and tender stems (about 30 g), rinsed and dried
½ cup mayonnaise (120 g)
⅓ cup sour cream (80 g)
1 medium jalapeño, stem removed and roughly chopped (about 15 g); remove the seeds for a milder sauce
1 small garlic clove, roughly chopped (about 3 g)
2 tbsp fresh lime juice for the sauce (30 ml)
1 tbsp olive oil (15 ml)
1 tsp white wine vinegar (5 ml)
1 tbsp ají amarillo paste, optional (15 g)
¼ tsp fine salt for the sauce (1.5 g), plus more to taste
1–3 tbsp cold water, as needed (15–45 ml)

Instructions

Make the chicken marinade. In a small bowl, mix the salt, black pepper, grated garlic, lime juice, soy sauce, neutral oil, cumin, paprika, oregano, and lime zest. Pat the chicken dry with paper towels. If you have time, gently loosen the skin over the breast and thighs with your fingers so some seasoning can reach the meat without tearing the skin. Rub the mixture over the whole chicken and underneath the loosened skin. Set the chicken in a covered dish or a food-safe bag and refrigerate for 4 hours. Keep it refrigerated throughout marinating; do not leave raw poultry on the counter.
Prepare the sauce. Add the cilantro, mayonnaise, sour cream, jalapeño, garlic, lime juice, olive oil, vinegar, ají amarillo paste if using, and ¼ teaspoon salt to a blender or food processor. Blend until smooth, stopping to scrape down the sides as needed. Add cold water a tablespoon at a time until the sauce is thick but easy to drizzle. Taste and adjust the salt, lime, or jalapeño. Transfer it to a clean covered container and refrigerate while the chicken roasts. The sauce can be made while the chicken marinates; keep it separate from anything that has touched raw poultry.
Heat the oven and set up the chicken. About 30 minutes before roasting, take the chicken out of the refrigerator so it loses some of its chill while the oven heats; do not leave it out longer than 2 hours. Heat the oven to 425°F (220°C). Set a rack in a roasting pan or sturdy oven-safe skillet. Tie the legs loosely with kitchen twine if you like, and tuck the wing tips behind the shoulders to help them cook evenly. Place the chicken breast-side up on the rack. If the skin looks wet from the marinade, blot it gently with a clean paper towel without wiping away the seasoning.
Roast until safely cooked. Roast at 425°F (220°C) for 15 minutes to start browning the skin. Without removing the chicken from the oven for long, lower the temperature to 375°F (190°C) and roast for about 55 minutes more. Begin checking the temperature then; a 4-pound chicken may need another 10–20 minutes depending on its shape, starting temperature, and oven. Insert an instant-read food thermometer into the thickest part of the breast and the innermost part of the thigh, avoiding bone. USDA FSIS safe minimum temperature for poultry is 165°F (74°C); check that both areas reach at least that temperature before removing the chicken. If the skin browns too quickly before the meat is done, loosely tent the browned areas with foil.
Rest, carve, and serve. Move the cooked chicken to a clean cutting board and let it rest for 15 minutes before carving. Resting gives the juices time to settle and makes the bird easier to carve; it is not a substitute for reaching the safe temperature in the previous step. Pour any pan juices into a small serving bowl, if desired. Carve the chicken into breast pieces, thighs, drumsticks, and wings, then serve with the chilled green sauce at the table.

Tips

Use a thermometer, not color alone. Roast times are a useful guide, but ovens and chickens vary. Check both the breast and thigh in their thickest areas, taking care not to touch bone, which can give a misleading reading. If either spot is below 165°F (74°C), return the chicken to the oven and check again after 5–10 minutes.
Dry skin browns better. Patting the chicken dry before seasoning helps the skin roast rather than steam. A rack lets hot air circulate underneath; if you do not have one, place thick onion slices in the pan and set the chicken on top. The vegetables may soften and catch flavorful drippings, though they will not lift the bird as evenly as a rack.
Adjust the heat thoughtfully. Jalapeños vary in strength, so start with half a pepper if you prefer mild sauce, then blend in more if needed. Ají amarillo paste adds a distinctive fruity, warm chile flavor; if it is unavailable, leave it out or add a little extra jalapeño. The result will still be delicious, but will not have quite the same flavor.
Keep raw and ready-to-eat foods separate. Use a clean plate and utensils for the cooked chicken, and wash your hands, cutting board, and tools after handling raw poultry. Do not reuse marinade that touched raw chicken as a finishing sauce unless it is brought to a full boil.

Serving Suggestions

Serve the carved chicken on a platter with the green sauce in a bowl so everyone can add as much as they like. For a familiar, satisfying plate, pair it with roasted potatoes, French fries, or rice, plus a simple green salad or sliced tomatoes and red onion. The sauce is rich and lively, so plain starches and crisp vegetables make especially good companions. Spoon a little sauce beside the chicken rather than over all of the crisp skin if you want the skin to stay crunchy.

For a casual meal, set out warm rolls or tortillas, shredded lettuce, and extra lime wedges so guests can make sandwiches or wraps with leftover slices. The pan juices can be served separately for anyone who wants a savory spoonful over potatoes or rice. If serving the sauce as a dip, keep it chilled until mealtime and put out a clean spoon rather than dipping utensils used for chicken into the bowl.

Variations

Use chicken pieces. Bone-in, skin-on thighs or drumsticks are convenient when you do not want to carve a whole bird. Coat them with the same marinade and arrange them in one layer, leaving space between pieces. They may cook faster than a whole chicken, so start checking early and use the thermometer rather than relying only on a set time. Each piece of poultry must reach 165°F (74°C).

Make the sauce more traditional in flavor. If you can find huacatay, a Peruvian herb with a minty, anise-like aroma, blend a small amount into the green sauce in place of some of the cilantro. It has a distinctive taste, so start with a teaspoon of paste or a few leaves and adjust. If it is not available, cilantro is a practical, fresh-tasting base; ají amarillo contributes fruity chile notes when you can find the paste.

Choose a different creamy base. Use plain Greek yogurt in place of some or all of the sour cream for a tangier sauce. For a dairy-free version, use a suitable plant-based mayonnaise and replace the sour cream with more of that mayonnaise or an unsweetened dairy-free yogurt. The texture and flavor will shift slightly, so thin with water gradually and rebalance with lime and salt.

Give the chicken a smoky edge. Replace the sweet paprika with smoked paprika, keeping the quantity the same. This adds a noticeable smoky aroma without changing the method. Avoid adding extra salt through a seasoning blend, since the soy sauce and measured salt already season the chicken.

Storage and Reheating

Refrigerate cooked chicken and sauce within 2 hours of cooking, storing them in separate airtight containers. Carved chicken keeps for 3–4 days in the refrigerator. The green sauce is best within about 3 days; its color may darken as the cilantro oxidizes, even when it has been stored cold. Discard either item if it has been left at room temperature for more than 2 hours, or 1 hour in temperatures above 90°F (32°C).

For the juiciest reheated chicken, place portions in a covered oven-safe dish with a spoonful of broth or pan juices and warm at 325°F (165°C) until the center reaches 165°F (74°C), checking with a food thermometer. Smaller portions can be reheated in the microwave in short bursts, turning or rearranging them for even heating; they must also reach 165°F (74°C). Reheat only the amount you plan to eat, and keep the green sauce chilled until serving rather than heating it with the chicken.

Frequently Asked Questions

Can I marinate the chicken overnight?

Yes. Keep it covered in the refrigerator and use it within 12 hours for this lime-and-soy marinade. Longer marinating is not necessary, and the acidic lime can affect the texture of the surface if left on for an extended period. If your schedule changes, cook the chicken within a day of seasoning it.

Can I make the green sauce ahead?

Yes. Blend it up to 2 days ahead, cover it, and refrigerate it. The cilantro may lose some of its vivid green color over time, but the flavor remains useful for serving. Stir before using, then add a teaspoon of water or lime juice if it has thickened in the refrigerator.

What can I use instead of ají amarillo?

It is fine to omit it. Ají amarillo is a yellow Peruvian chile with fruity flavor and moderate heat, and it can be difficult to find outside specialty shops. A little extra jalapeño brings heat but tastes greener and sharper; a pinch of mild chile powder can add warmth without recreating ají amarillo’s particular flavor.

How do I know when the whole chicken is done?

Use an instant-read thermometer, not the color of the juices or the clock alone. Check the thickest breast area and the innermost thigh without touching bone; both should reach at least 165°F (74°C), the USDA FSIS safe minimum for poultry. If one area is not there yet, continue roasting and check again after a few minutes.

Can I cook this chicken on a grill?

Yes, if your grill can maintain indirect heat. Set up a cooler zone, place the chicken over it with the lid closed, and cook until the thickest breast and innermost thigh each reach 165°F (74°C). Grill temperatures and cooking times vary, so use a thermometer and watch for flare-ups from dripping fat. The skin may brown differently from oven-roasted skin, but the marinade and green sauce still work well.

Can I freeze leftovers?

Freeze cooled carved chicken in airtight freezer-safe packaging for up to about 3 months for best quality, then thaw it in the refrigerator and reheat it to 165°F (74°C). The creamy cilantro sauce may separate or lose its fresh texture after freezing, so it is better made fresh or kept refrigerated for a few days.
