French Onion Baked Chicken ingredients

  • chicken – boneless, skinless chicken breasts are the lean protein of choice for this recipe.
  • salt and pepper – for seasoning everything to perfection.
  • olive oil – for searing the chicken breasts and sauteeing the onions.
  • onions – two yellow onions are the foundation of this dish. Caramelization brings out their natural sweetness.
  • garlic – enhances the depth of flavor of the onion mixture.
  • butter – adds richness and flavor to the onion mixture.
  • granulated sugar – just a small spoonful of sugar is my trick to getting onions to caramelize perfectly.
  • all-purpose flour – helps thicken the onion mixture into a nice sauce.
  • dry white wine – adds acidity to the sauce and deglazes the pan.
  • Worcestershire sauce – adds a savory, umami-filled kick.
  • thyme – fresh thyme leaves add an herbaceous note. You can also use half the amount of dried thyme.
  • beef broth – beef stock or broth is what is traditionally used in French onion soup, so that’s what I’ve used for this recipe. If you’d prefer to use chicken stock, you can, but the dish won’t taste as rich.
  • cheese – Grueyere is my cheese of choice to make the gooey, irresistible topping, but Swiss cheese also works great.

How to make French Onion Chicken

  2. Sear the chicken in a skillet until it’s golden brown on both sides, then transfer it to a plate.
  3. Cook the onions and garlic with butter, sugar and a bit more oil until the onions are dark golden brown.
  4. Stir the flour into the onions.
  5. Add the wine, Worcestershire sauce, thyme, and the rest of the salt and pepper and cook until most of the wine evaporates.
  6. Stir in the broth, then add the chicken back to the skillet.
  7. Sprinkle the cheese over the chicken and transfer the skillet to the oven to bake until the chicken is cooked through and the cheese is melted.

Home Chef Tips for this French Onion Chicken Recipe

  • Use an instant read thermometer to check the internal temperature of the chicken. Make sure it reaches 165 degrees F and no higher.
  • If you don’t have an ovenproof skillet, you can transfer the chicken and onion mixture to a baking dish before baking.

How to serve French Onion Soup Chicken

My favorite way to serve this French onion baked chicken is over basmati rice. I usually just use a microwave pouch because it’s so easy.

If I’m feeling motivated, I’ll also make a side of balsamic green beans or my recipe for glazed carrots, too.

Serving this dish with big hunks of crusty bread is never a bad idea, either.
