01 - Preheat oven to 425°F.
02 - Whisk together olive oil, lime juice, soy sauce, white vinegar, paprika, cumin, garlic powder, oregano, pepper, and salt in a small bowl until well combined.
03 - Pat chicken completely dry with paper towels. Rub marinade thoroughly over entire chicken, working under the skin and inside the cavity for maximum flavor penetration.
04 - Place chicken breast side up on a rack in a roasting pan. Let stand at room temperature for 20 minutes to allow marinade to penetrate.
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 - Transfer chicken to a cutting board and rest for 10 minutes before carving to allow juices to redistribute throughout the meat.
07 - Combine cilantro, jalapeños, garlic, mayonnaise, sour cream, lime juice, olive oil, salt, and pepper in a blender. Process until completely smooth and vibrant green.
08 - Carve chicken into portions and arrange on serving plates. Drizzle with creamy green sauce or serve alongside for dipping.
