Preheat your oven to 375°F (190°C) and grease a 9×13-inch baking dish with olive oil or cooking spray.
Season the chicken breasts with salt, pepper, and half of the oregano, basil, and thyme. Pound the chicken breasts to an even thickness if desired.
Slice the zucchini into rounds or half-moons. Toss the zucchini with olive oil, garlic, lemon juice, lemon zest, and the remaining herbs. Season with salt and pepper.
Place the seasoned chicken breasts in the center of the baking dish and arrange the zucchini around the chicken in an even layer.
Bake in the preheated oven for 25-30 minutes or until the chicken reaches an internal temperature of 165°F (75°C). Sprinkle cheese over during the last 5 minutes of baking.
Remove from oven and let rest for 5-10 minutes before slicing. Serve with roasted zucchini garnished with additional herbs or a drizzle of olive oil if desired.
