01 - Preheat oven to 400°F (200°C). Line a baking dish with parchment paper or lightly grease with oil.
02 - Pat chicken breasts dry. Coat both sides evenly with olive oil, Italian herbs, garlic powder, salt, and pepper.
03 - Heat a large skillet over medium-high. Sear chicken breasts for 2 to 3 minutes per side until golden but not fully cooked through.
04 - Transfer seared chicken to prepared baking dish. Arrange tomato and mozzarella slices over each breast.
05 - Bake for 15 to 18 minutes until chicken is cooked through (internal temperature 165°F/74°C) and cheese has melted.
06 - Meanwhile, in a small saucepan, combine balsamic vinegar and honey. Bring to a simmer over medium heat and cook, stirring frequently, until reduced by half and syrupy, about 8 to 10 minutes. Remove from heat.
07 - Remove chicken from oven. Rest for 2 to 3 minutes. Top with fresh basil leaves and drizzle generously with balsamic glaze. Serve immediately, spooning extra glaze over each portion.
