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 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 olive oil. Sauté minced garlic for 30 seconds until fragrant, being careful not to burn it.
04 - Add zucchini slices to the skillet. Cook for 3–4 minutes, stirring occasionally, until just tender and lightly golden.
05 - Stir in cherry tomatoes and red pepper flakes. Cook for another 2–3 minutes until tomatoes begin to soften and release their juices.
06 - Return chicken to the skillet, nestling it among the vegetables. Top each chicken breast with sliced mozzarella. Cover the skillet 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.
