Step 3

Preheat oven to 400 degrees F.

Step 4

Heat oil over medium-high heat in a large oven-safe skillet. Season the chicken all over with salt and pepper, to taste. When the pan is hot and oil is shimmering, add the chicken to the skillet in a single layer. Cook for 1-2 minutes on each side or until lightly golden brown. Add the balsamic sauce mixture. It should quickly come to a simmer. Use a wooden spoon to scrape up any brown bits from the bottom of the pan.

Step 5

Immediately remove the pan from the heat and add the tomato mozzarella mixture over the chicken.

Step 6

Bake uncovered for 18-23 minutes or until chicken is fully cooked through. Internal temperature should register at 165F. Remove from the oven and rest for 5 minutes before serving.
