01 - Pat chicken breasts dry with paper towels. Season both sides generously with salt, pepper, and Italian herbs, pressing the seasoning into the meat.
02 - Heat 1 tablespoon olive oil in a large skillet over medium-high heat until shimmering. Add chicken breasts and cook for 5–6 minutes per side until golden brown and internal temperature reaches 165°F. Transfer to a plate and tent with foil to keep warm.
03 - Add the remaining tablespoon of olive oil to the same skillet. Add minced garlic and sauté for 30 seconds until fragrant, being careful not to burn it.
04 - Add zucchini rounds to the skillet. Cook for 3–4 minutes, stirring occasionally, until just tender and beginning to show golden edges.
05 - Add cherry tomatoes and red pepper flakes. Cook for another 2–3 minutes until tomatoes start to blister and soften, releasing some juices.
06 - Return chicken to the skillet, nestling it among the vegetables. Arrange sliced mozzarella over each chicken breast. Cover with lid and cook for 2–3 minutes until cheese is melted and bubbly.
07 - Remove from heat. Drizzle balsamic glaze over the skillet, sprinkle with torn fresh basil leaves, and serve immediately while hot.
