Preheat the oven to 400 degrees Fahrenheit.
Gather your ingredients.
Mix all ingredients together. (Sorry I didn't have photos for adding everything in)
Put the chicken breast in a pan. I sliced the breast in half since they were on the larger side.
Add the mixture into the pan over the chicken. If you like onions, you can add them here (I was out of them :( )
Cover the chicken with tin foil.
Set the timer for 25 minutes.
Ta-da! French onion style chicken. Serve with your favorite side dish and enjoy!
