Store leftovers in an airtight container in the refrigerator for up to 5 days, or freeze for up to 3 months. Using chicken breasts of similar size ensures even cooking. Flipping the chicken halfway through reinforces browning and prevents uneven cooking. A meat thermometer will help you monitor the cooking, pulling the chicken at 165 degrees F to avoid dryness. If the chicken looks pale after cooking, consider adding extra olive oil or adjusting the cooking time for better browning.
