Ingredients
(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)
Chicken Breasts – Boneless, skinless chicken breasts provide the protein base and soak up the onion flavors beautifully.
Onions – Thinly sliced onions are slowly caramelized to bring out their natural sweetness and depth.
Beef Broth – Adds richness and a classic French onion soup flavor to the dish.
Garlic – Provides an aromatic, savory backbone that enhances the onion flavor.
Olive Oil or Butter – Used for sautéing onions until golden brown and flavorful.
Worcestershire Sauce – Deepens the broth with a tangy, umami note.
Salt and Black Pepper – Essential seasonings to enhance the overall flavor.
Thyme – A fragrant herb that complements the onion and broth.
Mozzarella Cheese – Melts into a gooey, stretchy topping.
Provolone or Swiss Cheese – Adds a nutty, slightly sharp flavor that balances the sweetness of onions.
Fresh Parsley – Used as a garnish for freshness and color.
Directions
Start by preheating the oven. In a large skillet, heat olive oil or butter and sauté sliced onions with garlic over medium-low heat. Stir occasionally until the onions become golden and caramelized. This process may take 20–25 minutes but is essential for developing deep flavor.
Once caramelized, add Worcestershire sauce, thyme, and beef broth. Simmer for a few minutes to blend the flavors, then remove from heat.
Arrange chicken breasts in a greased baking dish. Season with salt and pepper, then pour the onion and broth mixture over the chicken. Cover the dish with foil and bake until the chicken is nearly cooked through.
Uncover, top each chicken breast with slices of provolone or Swiss cheese, followed by mozzarella. Return to the oven and bake until the cheese is melted, bubbly, and golden. Garnish with fresh parsley and serve warm.
