Peruvian Chicken Yellow Sauce Recipe: Aji Amarillo Creamy Spiced Delight

This recipe brings the vibrant flavors of Peru to your kitchen with its signature creamy aji amarillo sauce. The sauce transforms simple chicken into a dish that’s rich, slightly spicy, and utterly addictive.

I developed this version after trying countless variations, perfecting the balance between the pepper’s fruity heat and the sauce’s velvety texture. The result is tender chicken coated in a golden sauce that’s both comforting and exotic.

Ingredients for Peruvian Chicken Yellow Sauce

Pantry staples meet specialty Peruvian paste for bold, creamy flavor.

The aji amarillo paste is non-negotiable here. Latin markets usually carry it, or order online—La Costeña or Inca’s Food are solid brands. Look for the bright yellow color, not the dark orange kind (that’s a different pepper). Chicken thighs stay juicier than breasts, but if you prefer white meat, breasts work too—just don’t overcook them.

No aji amarillo? Yellow bell pepper plus a pinch of cayenne gets you close, but it won’t be the same. Out of mayonnaise? Greek yogurt at one-to-one ratio works in a pinch. The sour cream can be swapped for crème fraîche if you’ve got it. For extra depth, add a splash of white wine when deglazing the pan.

Sauce thickens as it cools, so serve immediately. Keeps in the fridge for 3-4 days, but the sauce may separate—just whisk it back together. Freezes for up to 3 months (the potatoes won’t freeze well, so add those fresh).

Step-by-Step Instructions for Peruvian Chicken in Yellow Sauce

Here’s the method. Straightforward, tested, works every time.

Step 1: Sear the Chicken Thighs

Heat the 2 tbsp vegetable oil in a large skillet over medium-high heat. While it heats, pat the 2 lb chicken thighs dry with paper towels and season both sides with the 1 tsp salt and 0.5 tsp black pepper.

Add the chicken to the hot oil and sear for 5-6 minutes per side until golden brown and cooked through. The thighs should release easily from the pan when they’re ready to flip. Transfer the cooked chicken to a plate and set aside.

Step 2: Sauté Aromatics and Build the Sauce Base

In the same skillet, reduce heat to medium and add the finely diced yellow onion. Sauté for 3-4 minutes until softened and just beginning to turn translucent.

Add the 4 cloves minced garlic cloves, 1 tsp ground cumin, and 0.5 tsp turmeric. Stir constantly for 30 seconds until fragrant. This is when the kitchen starts to smell incredible.

Step 3: Create the Creamy Aji Amarillo Sauce

Stir in the 0.5 cup aji amarillo paste and cook for 1 minute, stirring constantly. The paste will deepen in color slightly. Pour in the 0.5 cup chicken broth and scrape up any browned bits from the bottom of the pan.

Reduce heat to low and whisk in the 0.75 cup mayonnaise and 0.5 cup sour cream until smooth. Let the sauce simmer gently for 2-3 minutes until it thickens slightly and becomes velvety.

Step 4: Finish with Chicken and Potatoes

Return the chicken to the skillet along with any accumulated juices. Add the 1.5 lb peeled and cubed yellow potatoes to the sauce. Stir everything together gently to coat the chicken and potatoes completely.

Cover and let it all warm through for 5-7 minutes on low heat. The potatoes should become tender but still hold their shape. Stir in the 2 tbsp lime juice just before serving.

Step 5: Garnish and Serve

Taste and adjust seasoning if needed. Transfer to a serving platter and sprinkle with the 0.25 cup chopped fresh cilantro. The sauce should be creamy and rich, clinging beautifully to the chicken and potatoes.

Serve immediately while hot. The flavors meld together even more as it sits, but it’s at its best fresh from the pan with that vibrant yellow color and aromatic cilantro on top.

Health Benefits of This peruvian chicken yellow sauce

Rich in Antioxidants

The aji amarillo paste brings more than just flavor—it’s packed with vitamin C and carotenoids that support immune health. These antioxidants help combat oxidative stress in your body. A single serving provides a meaningful boost to your daily intake. 💪

Healthy Fats Source

Both mayonnaise and sour cream contain monounsaturated fats from their oil and dairy bases. While moderation is key, these fats support heart health and help your body absorb fat-soluble vitamins like vitamin A from the turmeric and peppers.

Protein-Packed Meal

The 2 lb chicken thighs provide about 100g of protein for the entire dish, making this a satisfying, muscle-building meal. Chicken thighs also contain iron and zinc, essential minerals for energy and immune function.

Potassium from Potatoes

Yellow potatoes add a hefty dose of potassium—about 600mg per serving—which helps regulate blood pressure and muscle function. They also provide fiber for digestive health, especially when you leave the skin on. 💛

Anti-Inflammatory Spices

The turmeric and cumin in this recipe aren’t just for flavor. Curcumin in turmeric is a powerful anti-inflammatory compound, while cumin aids digestion. Together, they make this dish as nourishing as it is delicious.
