01 - Pat chicken breasts dry with paper towels and season both sides generously with salt and black pepper.
02 - Heat olive oil in a large skillet over medium-high heat. Add chicken breasts and sear for 3–4 minutes per side until golden brown. Remove from pan and set aside.
03 - In the same pan, add red onion and sauté for 2 minutes until slightly softened. Add garlic and cook for 30 seconds until fragrant.
04 - Stir in cherry tomatoes and cook for 3–4 minutes until they start to release juices and soften.
05 - In a small bowl, whisk together balsamic vinegar, chicken broth, and honey. Pour mixture into the pan, scraping up any browned bits from the bottom.
06 - Return the chicken breasts to the skillet, nestling them among the vegetables. Sprinkle with thyme and chopped basil. Reduce heat to low, cover, and simmer for 12–15 minutes, or until chicken is cooked through (internal temperature reaches 165°F).
07 - Remove lid and simmer uncovered for 2–3 minutes to allow the sauce to reduce and thicken slightly.
08 - Plate the chicken topped with the pan sauce and vegetables, garnished with extra fresh basil leaves.
