Heat the oven to 200°C / 400°F. Lightly coat a 23 × 33 cm baking dish with the olive oil.

Pat the chicken dry. If one end is much thicker, gently flatten it to an even thickness of about 2 cm. Arrange in one layer with a little space between the breasts.

Spread the pesto over the chicken. Halve the cherry tomatoes and scatter them around the chicken. Sprinkle with black pepper.

Bake uncovered for 20 minutes. Scatter mozzarella over the chicken and bake for another 5–10 minutes, until the cheese melts and the thickest part of each breast reaches 74°C / 165°F. Larger pieces may need longer.
05 -
Rest for five minutes. Spoon the tomato and pesto juices over the chicken before serving. Slice one breast across the grain to show the juicy interior.

Refrigerate leftovers within two hours and use within three days. Reheat covered with the pan juices until the chicken reaches 74°C / 165°F.
