Instructions

Caramelize the Onions: Heat the butter and olive oil in a large skillet over medium heat. Add the thinly sliced onions and cook slowly, stirring often, for 20 to 25 minutes until they are deeply caramelized and golden brown, developing their natural sweetness and rich flavor.
Add Garlic and Simmer Sauce: Stir in the minced garlic and cook for 1 minute until fragrant. Then add the beef broth, white wine (or additional broth), Worcestershire sauce, thyme, salt, and pepper. Let the mixture simmer for 5 minutes to meld the flavors together.
Cook the Chicken: Season the chicken breasts with salt and pepper. Push the caramelized onions to one side of the skillet, and add the chicken breasts to the pan. Cook for 5 to 6 minutes on each side, or until the chicken is browned and cooked through.
Add Cheese and Melt: Spoon the caramelized onions over the cooked chicken. Sprinkle shredded Gruyère or Swiss cheese evenly on top. Cover the skillet and cook for another 2 to 3 minutes, or until the cheese is melted and bubbly.
Serve: Serve the French Onion Chicken hot, spooning the savory onion sauce over each piece. This dish pairs wonderfully with mashed potatoes or crusty bread to soak up the delicious juices.

Notes

For extra flavor and a lightly browned cheese topping, finish the dish under the broiler for 1 to 2 minutes—watch carefully to prevent burning.
Substitute chicken thighs instead of breasts for a juicier and more flavorful option.
Serve with mashed potatoes, rice, or crusty bread to enjoy every bit of the onion and cheese sauce.
