Ingredients

Scale

Chicken and Seasonings

  • 4 boneless, skinless chicken breasts
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon dried thyme
  • 1 teaspoon salt
  • ½ teaspoon black pepper

Onions and Sauce

  • 2 tablespoons olive oil
  • 2 large yellow onions, thinly sliced
  • 1 tablespoon balsamic vinegar
  • 1 cup beef broth
  • 1 tablespoon all-purpose flour (optional, for thickening)

Cheese Toppings

  • 1 cup shredded mozzarella cheese
  • ½ cup shredded Gruyère or Swiss cheese

Garnish

  • Chopped fresh parsley


Instructions

  1. Caramelize Onions: Preheat the oven to 375°F (190°C). Heat olive oil in a large skillet over medium heat. Add the thinly sliced onions and cook, stirring frequently, for 15 to 20 minutes until they are golden and caramelized. Stir in the balsamic vinegar and cook for an additional minute to enhance the flavor.
  2. Season Chicken: While the onions caramelize, season both sides of the chicken breasts evenly with garlic powder, onion powder, dried thyme, salt, and black pepper to build a flavorful base.
  3. Arrange in Baking Dish: Lightly grease a 9×13-inch baking dish and place the seasoned chicken breasts inside in a single layer. Evenly spread the caramelized onions over the top of the chicken.
  4. Prepare Sauce: In the same skillet used for the onions, add the beef broth and sprinkle in the optional flour to thicken the sauce slightly. Simmer for 2 to 3 minutes, stirring to combine and develop a rich savory sauce.
  5. Assemble and Bake: Pour the beef broth mixture over the chicken and onions in the baking dish. Sprinkle the shredded mozzarella and Gruyère cheeses evenly on top. Bake uncovered for 25 to 30 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the cheese is melted and bubbly.
  6. Garnish and Serve: Remove from the oven and sprinkle with chopped fresh parsley for a burst of color and fresh flavor. Serve immediately, ideally over mashed potatoes, rice, or with crusty bread to enjoy the delicious sauce.

Notes

  • Use homemade beef broth and freshly shredded cheese for the richest flavor.
  • Chicken thighs can be substituted for chicken breasts for more juiciness.
  • For a gluten-free version, omit the all-purpose flour or use a gluten-free alternative.
  • Serve with mashed potatoes, rice, or crusty bread to soak up the flavorful sauce.
