Mix the Magic: In a large bowl, whisk together all marinade ingredients until smooth and glossy.
Save Some Shine: Set aside 2–3 tbsp of the marinade in a small bowl for basting later.
Rub with Love: Coat the chicken thoroughly in the remaining marinade, making sure to get under the skin for max flavor.
Let It Soak: Cover and marinate for 8–12 hours (overnight is best—trust me).
Preheat Like a Pro: When ready to cook, preheat oven to 400°F (200°C).
Set the Stage: Place a wire rack over a foil-lined baking sheet and arrange chicken in a single layer.
Bake to Glory: Roast 40–50 minutes, basting halfway with reserved marinade.
Gloss It Up: Brush with remaining marinade in the last 5 minutes for that shiny, rotisserie-style finish.
Grill Option: Fire up a medium-high grill, flipping often and brushing with reserved marinade until caramelized and golden.
Blend the Sauce: Add cilantro, jalapeños, green onions, garlic, and ají amarillo paste to a blender. Blend until finely chopped.
Cream It Out: Add mayonnaise, Greek yogurt, lime juice, vinegar, olive oil, salt, and pepper. Blend until smooth and luscious. Add water, 1 tbsp at a time, until it’s creamy but pourable.
Let It Chill: Refrigerate for at least 30 minutes so flavors can mingle and the color deepens.
Serve Like You Mean It: Plate the chicken hot with roasted potatoes, fries, or rice. Drizzle that green sauce like it’s liquid gold. Garnish with lime wedges and serve extra sauce on the side—because one spoonful will never be enough.
