• Prepare caramelized onions and chicken up to two days in advance, storing separately in refrigerator to streamline meal preparation and reduce day-of cooking stress.
• Use a cast-iron skillet or oven-safe pan to minimize dishes and transfer seamlessly from stovetop to oven, ensuring maximum flavor retention and easier cleanup.
