Season the chicken breasts with salt and pepper. Place them in a greased baking dish.
Spoon the pesto evenly over each chicken breast, ensuring they’re well-coated.
Arrange slices of fresh mozzarella over the pesto-covered chicken, then layer the tomato slices on top.
Drizzle a tablespoon of olive oil over the assembled dish for extra flavor.
Cover the dish with aluminum foil and bake in the preheated oven for 25-30 minutes. After that, remove the foil and bake for an additional 10-15 minutes or until the chicken is cooked through (internal temperature should reach 165°F/75°C) and the cheese is bubbly and slightly golden.
Once cooked, remove from the oven and let it rest for a few minutes. Garnish with fresh basil leaves before slicing and serving.
Notes
Let the dish rest before serving for better flavor.
