01 - In a bowl, whisk together lemon juice, lemon zest, vanilla extract, honey, fresh basil, and minced garlic until combined.
02 - Place chicken breasts in a resealable bag or shallow dish. Pour marinade over chicken, seal, and refrigerate for at least 30 minutes, up to 2 hours for enhanced flavor.
03 - Preheat the oven to 400°F. Line a baking sheet with parchment paper.
04 - In a shallow dish, combine finely chopped mixed nuts, grated Parmesan, chopped basil, and lemon zest.
05 - Remove chicken from marinade, discarding excess liquid. Pat dry with paper towels. Lightly brush with olive oil, then press each breast into the nut mixture, coating evenly on both sides.
06 - Place coated chicken breasts on the prepared baking sheet. Season with kosher salt and freshly ground black pepper.
07 - Bake for 20 to 25 minutes until the nut crust is golden and the internal temperature of the chicken reaches 165°F.
08 - Allow chicken to rest for 5 minutes before serving. Garnish with extra lemon wedges and fresh basil leaves.
