1. Place the chicken in a roasting pan. Add the garlic, fennel, parsley, wine, lemon juice, salt, and pepper and use your hands to mix well. Marinate at room temperature for 10 minutes or cover and marinate in the fridge for up to 24 hours.
2. Preheat the oven to 400°F (200°C).
3. Roast the chicken for 20 minutes. Reduce the oven temperature to 300°F (150°C) and continue to roast for 1 hour and 40 minutes longer, basting with the pan juices twice during cooking. Sprinkle the peas into the pan and continue to roast until the chicken is golden and crisp, about 20 minutes longer. Serve right away.
