Ingredients Needed

Labeled ingredients for french onion chicken bake.
  • Chicken Breasts: You can also use chicken thighs if you prefer, but my go-to for this recipe is boneless skinless chicken breasts.
  • Seasonings: Use a blend of Italian seasoning, garlic powder, cloves, and thyme.
  • Cheese: For a nice melted cheese, I like to use something mild like provolone as well as Parmesan cheese for salty flavor.
  • Onions: I like to use sweet onions here, but feel free to substitute vidalia onions, white onions, or yellow onions.
  • Olive Oil
  • Butter
  • Sherry Wine: Deepens the flavors and helps to deglaze the skillet. White wine works as well.
  • Soy Sauce: Gives the dish a more complex umami flavor--use low sodium soy sauce to avoid adding to much saltiness.
  • Beef Stock: You can also use a low sodium beef broth to keep things light, or even substitute chicken broth or vegetable broth instead.

How to Make this French Onion Chicken Bake

Steps 3 through 6 for making a french onion chicken bake.

  • Step 3: To the onions, add garlic and thyme and cook until fragrant.
  • Step 4: Add sherry wine and scrape the bottom of the pan. Add soy sauce and beef stock and simmer until slightly thickened.

Recipe Tips

  • If you don't have an oven-safe skillet, you can bake your chicken in a casserole dish or another baking dish. After you've made the onion mixture with the savory broth, add it to the casserole dish with the chicken, bake for 8 minutes, then add cheese and bake another 10-15 minutes.
  • If you choose to use chicken thighs, they may need an extra minute or two. Chicken is fully cooked when it reaches an internal temperature of 165 degrees, so use an instant-read thermometer to check on it.
  • Feel free to substitute other cheeses like Swiss cheese, Gruyere cheese, or mozzarella.
  • Allow leftovers to cool and transfer to an airtight container in the fridge for 3 to 4 days.
  • To reheat leftovers, return to a pan over medium heat or pop back in the oven at 350 degrees F until everything is properly heated through.

Recipe FAQ's

Why is it called French Onion?

French onion soup is named for its origins in France, where it became a staple dish in the 17th century. It features caramelized onions, provolone cheese, Gruyere cheese, and thyme. The classic presentation with toasted bread and melted cheese on top further ties the dish to French culinary tradition.

Is it better to bake chicken at 350 or 400 degrees F?

Because the baking is just to finish off the chicken and melt the cheese, I actually go for 450 degrees in this dish. Ideally, your onion chicken bake will only be in the oven for 10 minutes, so the high heat won't be enough to dry it out.
