How Do I Make French Onion Chicken?

  1. To have the chicken breasts cooked evenly, we need to pound them thin to the same thickness. Cover them with plastic wrap and pound them to ¾-inch thick.
  2. Season the chicken with salt, pepper, and dried thyme.
  3. Heat 1 ½ tbsp olive oil in a large skillet over medium-high heat and brown the chicken breasts for about 5 minutes on each side. The skillet has to be very hot before placing the chicken in it.
  4. Transfer the browned chicken breasts to a plate and wipe the skillet clean with a paper towel.
  5. Heat the skillet over medium heat and melt the butter along with the remaining 1 ½ tbsp olive oil. Add the sliced onions and cook them for about 20 minutes or until golden brown and caramelized. Add the minced garlic and cook 30 seconds more.
  6. Mix in the flour until well combined and pour in the beef broth and Worcestershire sauce. Mix well.
  7. Return the chicken breasts to the skillet, place two fresh thyme sprigs on top, and simmer for about 20 minutes or until the sauce is thick and the chicken is cooked through.
  8. Top each breast with two slices of mozzarella cheese, place the lid on top, and cook until the cheese has melted.

Why Is It Called French Onion Chicken?

This recipe is reminiscent of the famous French Onion Soup. Both are made with caramelized onions and a hearty beef sauce. Thyme is the herb of choice in both recipes, and melted cheese is the signature topping for the soup as well!

Ingredients

  • 4 skinless, boneless chicken breasts
  • 1 tsp dried thyme
  • Salt and pepper to taste
  • 3 tbsp olive oil
  • 1 ½ tbsp butter
  • 2 yellow onions, thinly sliced
  • 2 garlic cloves, minced
  • 2 tbsp all-purpose flour
  • 1 cup beef broth
  • 1 tbsp Worcestershire sauce
  • 2 sprigs fresh thyme
  • 8 slices mozzarella cheese

Instructions

  • To have the chicken breasts cooked evenly, we need to pound them thin to the same thickness. Cover them with plastic wrap and pound them to ¾-inch thick.
  • Season the chicken with salt, pepper, and dried thyme.
  • Heat 1 ½ tbsp olive oil in a large skillet over medium-high heat and brown the chicken breasts for about 5 minutes on each side. The skillet has to be very hot before placing the chicken in it.
  • Transfer the browned chicken breasts to a plate and wipe the skillet clean with a paper towel.
  • Heat the skillet over medium heat and melt the butter along with the remaining 1 ½ tbsp olive oil. Add the sliced onions and cook them for about 20 minutes or until golden brown and caramelized. Add the minced garlic and cook 30 seconds more.
  • Mix in the flour until well combined and pour in the beef broth and Worcestershire sauce. Mix well.
  • Return the chicken breasts to the skillet, place two fresh thyme sprigs on top and simmer for about 20 minutes or until the sauce is thick and the chicken is cooked through.
  • Top each breast with two slices of mozzarella cheese, place the lid on top and cook until the cheese has melted.

Notes

  1. To properly brown the chicken breasts, the skillet should be hot and the oil should be hot too prior to cooking the chicken.
  2. To properly caramelize the onions, cook them on medium-low heat, not high heat.
  3. The mozzarella cheese melts just by placing the lid on top. The steam alone melts the cheese.
