01 - Preheat the oven to 400°F. Lightly grease a baking dish with cooking spray or oil.
02 - Season both sides of each chicken breast generously with salt and freshly ground black pepper.
03 - In a medium bowl, whisk together the orange zest and juice, lemon zest and juice, olive oil, minced garlic, chopped rosemary, chopped thyme, and honey until well combined.
04 - Place chicken breasts in a resealable plastic bag or shallow dish. Pour the marinade over the chicken, ensuring all pieces are evenly coated. Marinate for at least 15 minutes, up to 2 hours for deeper flavor penetration.
05 - In a separate bowl, combine the finely chopped mixed nuts, breadcrumbs, chopped parsley, and smoked paprika. Mix thoroughly to distribute spices evenly.
06 - Remove chicken from the marinade and discard the used marinade. Press each chicken breast firmly into the nut mixture, coating well on all sides and pressing gently to adhere the crust.
07 - Place the coated chicken breasts in the prepared baking dish, ensuring they are not overcrowded for even cooking.
08 - Bake for 25–30 minutes, or until chicken is cooked through and the nut crust is golden brown. The internal temperature should reach 165°F when measured with a meat thermometer.
09 - Let the chicken rest for 5 minutes before serving to allow juices to redistribute. Garnish with additional fresh herbs and citrus zest if desired.
