01 - Pat chicken breasts dry with paper towels. Season both sides generously with salt, pepper, and Italian herbs, pressing the seasoning into the meat to adhere.
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 cover loosely with foil to keep warm.
03 - In the same skillet, add remaining tablespoon of olive oil. Add minced garlic and sauté for 30 seconds until fragrant, being careful not to burn it.
04 - Add zucchini slices to the skillet and cook for 3–4 minutes, stirring occasionally, until just tender but still holding their shape.
05 - Add cherry tomatoes and red pepper flakes. Cook for another 2–3 minutes, stirring gently, until tomatoes begin to soften and release their 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 with balsamic glaze and sprinkle with torn fresh basil leaves. Serve immediately while hot.
