• Swap in boneless, skinless chicken thighs for a juicier result.
• Yellow squash can replace some or all of the zucchini; thin-sliced eggplant also works.
• Tomatoes release liquid as they bake—leave the dish uncovered for the last 10 minutes if you want it less saucy.
• For fresh herbs, use about 3x the amount of dried.
• Store leftovers covered in the refrigerator for up to 4 days; reheat gently.
• To prep ahead, chop chicken and vegetables the night before and store separately, then toss and bake when ready.
• Optional add-ins: bell peppers, olives, or artichoke hearts.
