Y’all know I love a quick and easy recipe. And Southerners love onions and chicken. My husband would eat caramelized onions every night of the week if he could.

This chicken is so good and stays juicy (if you don’t overcook it—use that thermometer!). If your kids don’t want the onion, you can just leave it off their piece.

Testing results for French onion chicken

  1. We tested this recipe with boneless, skinless chicken breasts, but chicken thighs would work perfectly. You would need to adjust the cooking time accordingly — again, use a thermometer for best results!

Ingredient notes

Here are a few things to know about the ingredients in this recipe.

Boneless skinless chicken breasts: You can substitute with chicken thighs.

Red wine: A good dry wine, something you would drink. I like a Pinot Noir in this recipe. If you don’t drink alcohol, it does cook off and just adds a little flavor. But you can also just use additional beef broth if you prefer.

Gruyere cheese: We like the distinct nutty flavor of Gruyere, but provolone or mozzarella would be fine.

How to make French onion chicken

  1. Cook the chicken on both sides in an oven-proof skillet.
  2. Remove the chicken, then add the butter and onions to the skillet. Cook the onions until caramelized to the extent that you want, then place the chicken back in the skillet.
  3. Cover the chicken with onions, sauce, and cheese, then broil until the cheese melts.
