Can this be made gluten free?
Yes, you can make this a gluten free dish if you substitute corn starch for the flour in the sauce. Start with 1 1/2 Tablespoons corn starch for 3 Tablespoons of flour. I also recommend checking labels for your French onion soup and chicken broth to ensure both products are gluten free.

Pro Tips
- This is a great meal to cook if you happen to have leftover French onion soup in your refrigerator.
- Gruyere cheese or Swiss cheese would be great substitutions for mozzarella.
- It is recommended that cooked chicken reaches an internal temperature of 165 degrees Fahrenheit to be safe to consume.
How do i know when the chicken is cooked through?
Chicken is safe to eat when juices run clear and it reaches an internal temperature of 165 degrees Fahrenheit. Use a meat thermometer to help you determine whether your French onion chicken is ready to eat or not.
how to store leftovers
FRIDGE: Store cooked and cooled baked French onion chicken in an airtight container 3-4 days.
FREEZER: If you want to freeze leftovers, I recommend putting chicken, onion and sauce in freezer safe individual containers and wrap them well with plastic wrap before putting on the lid.
how to reheat leftovers
Reheat leftover French onion chicken in the oven at 350 degrees Fahrenheit for about 15 minutes or until hot throughout.
If you are only reheating one or two servings, you can reheat covered on the stovetop or even in the microwave.
French Onion Chicken is such a great meal idea based on such a comforting soup. It is quite simple and not too time consuming. Everyone will love soaking up all of the extra gravy with their potatoes or bread.
