01 - Preheat your oven to 425°F.
02 - In a small bowl, whisk together olive oil, lime juice, soy sauce, white vinegar, paprika, cumin, garlic powder, oregano, pepper, and salt until well combined.
03 - Pat the chicken completely dry with paper towels. Rub the marinade thoroughly over the entire chicken, working it under the skin and inside the cavity for maximum flavor penetration.
04 - Place the chicken breast side up on a rack in a roasting pan. Let it marinate at room temperature for 20 minutes, or refrigerate for up to 12 hours for deeper flavor development.
05 - Roast for 1 hour to 1 hour 10 minutes, until the thickest part of the thigh reaches 165°F and juices run clear when pierced.
06 - Remove from the oven and let the chicken rest for 10 minutes before carving. This allows the juices to redistribute throughout the meat.
07 - While the chicken rests, combine cilantro, jalapeños, garlic, mayonnaise, sour cream, lime juice, olive oil, salt, and pepper in a blender or food processor. Blend until completely smooth and vibrant green.
08 - Carve the rested chicken into serving pieces. Serve immediately with the creamy green sauce on the side for drizzling or dipping.
