• Store leftover chicken in an airtight container in the refrigerator for up to 3-4 days. The caramelized onion sauce keeps the meat super tender when reheated.
• Freeze individual portions wrapped tightly in plastic wrap and sealed in a freezer bag. Thaw overnight in the refrigerator before gently reheating to maintain the chicken’s moisture.
• When reheating, cover your dish with foil to prevent the cheese from burning and keep the chicken from drying out. Warm at 325°F for about 15 minutes.
• If the sauce separates after refrigeration, simply whisk it gently when reheating to restore its creamy texture and help the flavors blend back together smoothly.
