  • 2 Tablespoons Olive Oil
  • 4 Chicken Breast, Boneless, Skinless
  • Salt
  • Black Pepper
  • 1 Teaspoon Italian Seasoning
  • 2 Large Yellow Onions, Cut Into 1/4 Inch Slices
  • 2 Tablespoons Butter
  • 3 Tablespoons Flour
  • 1 Cup Beef Broth
  • 1 Cup Chicken Broth
  • 2 Tablespoons Sherry
  • 1/4 Teaspoon Thyme Leaves
  • 1 Cup Gruyere cheese, Shredded


  1. Preheat oven to 350 degrees.

  2. Pat chicken breast dry with paper towels to remove any moisture from packing. Generously season both sides with salt, pepper, and Italian seasoning.

  3. Heat oil over medium heat in a high sided, oven-safe skillet. When oil begins to shimmer, add chicken breast. Brown on each side, 4-6 minutes. Remove to a plate and set aside. 

  4. Add 2 tablespoons of butter to the same skillet and melt. Add the onions to the melted butter and cook, stirring until the onions begin to soften. Add 1/4 teaspoon salt.

  5. Reduce heat to medium-low (lower heat as needed so onions don't burn) and continue to cook, stirring often, until the onions are soft but not mushy. Sprinkle the onions with flour and toss to coat.

  6. Add the beef and chicken broth, sherry and thyme to the onions. Bring to a boil, scraping up any brown bits on the bottom of the pan. Boil for 1-2 minutes or until sauce is thick.

  7. Add chicken back to pan and nestle into onion mixture. Spoon some sauce over the chicken. Top with Gruyere. 

  8. Place skillet in preheated oven and cook until the cheese is melted and bubbly. It's better not to brown the cheese, just allow it to melt. Adjust seasoning if need. Spoon a little onion mixture and sauce over chicken, top with fresh thyme or chopped parsley(optional) and Serve.

Recipe Notes For French Onion Chicken:

Cheese: The cheese in this dish plays a starring role. Like authentic French Onion soup, our recipe calls for Gruyere cheese but you can substitute the Gruyere with Swiss and still have great flavor.

  • Gruyere cheese: If you aren’t familiar with this cheese, it’s a fairly dense, semi-soft cheese that originated in Switzerland. It has a brownish rind that I remove. Because it’s on the firmer side, I find it’s easiest to shred it, rather than slice it. The flavor is really wonderful and adds fabulous complexity to the flavor of this recipe. This is the brand I use most often.
  • Swiss Cheese: I love the flavor of Swiss, and I can buy it pre-sliced at the supermarket. Using sliced cheese rather than shredded produces a neater appearance to the finished dish.

Oven: If you’d like to try a french onion chicken bake in the oven, this is a great recipe version to try it with. Preheat the oven to 350, and make the sauce in a skillet on the stove top as directed. Pour it over the seasoned chicken breast and bake until cooked through. Top with cheese and put back in the oven until bubbly.

Crunchy French Onion Chicken: You can make a crispy, crunchy version of this chicken that is super fun and really yummy. Before you put the chicken in the skillet to brown it, crunch up a bowl full of store-bought fried onions. Beat an egg. Dip the chicken into the egg and then into the onions. Coat it well and place it in the pan. Follow the rest of the recipe as is. So good!

French Onion Chicken Thighs:A wonderful option. Simply sub the chicken breasts for the thighs and PRESTO! The flavor is great, and the thighs add a different consistency to the meal. Boneless thighs are better, and the cook time will not vary as much.

Can You Make French Onion Chicken Ahead Of Time?

This tasty onion chicken is definitely one that you can throw together ahead of time. You’ll want to follow every step of the recipe right up until you’re supposed to put it all in the oven. Cover it tightly and place it in the refrigerator until you’re ready to bake it. Take it out, top with cheese and pop it in a preheated oven. Using all the food blogger honesty I can muster, this is really a recipe that tastes best when it’s all made at once. If you’re in a pinch, and simply must make it ahead, this is the best method.

How Do You Freeze French Onion Chicken?

The best way to freeze French onion chicken is to wrap up your leftovers and toss them in the freezer. I like to portion them out into freezer safe containers! Take one out, heat it through and poof, you have dinner. Of all chicken and onions recipes, this one freezes rather well. Just be sure to follow those trusty food safety guidelines!

What Do You Serve With French Onion Chicken?

French onion chicken is packed with flavor, and bathed in a delicious sauce. I like to serve plain white rice, buttered egg noodles, or fresh crusty bread to make sure I have a side that will soak up all of that sauce. Save your table manners for another meal. Other than that I generally add a simple salad or easy Roasted Broccoli.
