What is in French Onion Chicken?

bowls with chicken, onion, butter, garlic, garlic powder, cheese, beef broth, oil, flour, paprika, salt, pepper and rosemary. the ingredients to make French onion chicken
  • Chicken Breast – for this recipe we recommend boneless skinless chicken breast. The chicken is incredibly tender and moist. If preferred you can use boneless skinless chicken thighs.
    • Chicken Seasoning – garlic powder, paprika, salt and pepper
  • Onions – we can’t have a French onion gravy without onions! Thinly sliced onions are the base of the gravy. We recommend using regular white or yellow cooking onions for this recipe. Try to avoid using an overly sweet onion like Vidalia as the gravy will be too sweet.
  • Garlic – cooked into the gravy… and in our books everything is better with garlic!
  • Butter and Flour – this combination creates a roux and thickens the gravy.
  • Beef Broth – we love the deep colour and flavor that beef broth adds to the gravy. You can also use chicken or vegetable broth if you prefer. For added nutrients use bone both!
  • Cheese – French onion soup is traditionally made with Gruyere cheese, however, it is often difficult to find in grocery stores. You can swap the Gruyere for Swiss cheese, provolone or even mozzarella.

Tips for the Best French Onion Chicken

  • One Pan – the great thing about this recipe is that is a one pan meal! To make this recipe using only one pan be sure to use an oven-safe frying pan (for example a cast iron skillet). This way you can make the gravy and chicken in the pan, top the chicken with the cheese and then transfer the pan right to the oven to finish cooking. If you do not have an oven-safe frying pan that is no problem. Use a regular frying pan to prepare the recipe and then you can transfer everything to a casserole dish or baking pan for the baking portion of the recipe.
  • Chicken – for the most tender and moist chicken, when pan frying the chicken do not completely cook as it will continue to cook during the braising time. All you need is a nice sear to seal in the juices.
  • Onions – caramelized onions are something so special. To achieve the best caramelized onions you need to be patient and cook the onions low and slow until they start to brown. Trust us when we say your patience will pay off and you will be left with the most amazing French onion gravy!
  • Cheese – traditional French onion soup is made with Gruyere cheese. However, you can really use any white cheese for this recipe. Get creative and try mozzarella, jalapeno Monterrey Jack for some heat, Havarti for extra creaminess, Swiss or Gouda are also great choices.
