Chicken marsala may be stored in the refrigerator for three to four days. Store it in an airtight container, once it has reached room temperature.
I recommend refrigerating the dish within two hours of cooking.
Chicken marsala can be frozen for up to 3 months.
To freeze, Place the cooled Chicken Marsala in a freezer-safe container or bag. Make sure to remove any excess air to prevent freezer burn.
I recommend dividing the Chicken Marsala into individual portions before storing it. This way, you can thaw and reheat only the amount you need without having to defrost the entire batch.
When you're ready to enjoy the Chicken Marsala, thaw it in the refrigerator overnight if it is frozen.
To reheat the chicken marsala, place it in a small pot and set it over low heat. Add a splash of chicken stock or water to thin out the sauce if necessary. Stir while it’s heating up so that it doesn’t burn.
Heat it till its internal temperature reaches 165 degrees Fahrenheit (74 degrees Celsius).
