How to Make French Onion Chicken

  1. Heat the Oil: Pour 1/4 cup of olive oil into a large oven-safe skillet and heat it over medium heat. This will create the perfect environment for caramelizing your fragrant onions.

  2. Caramelize Onions: Add the sliced Vidalia onions, sprinkle with salt, and saut until they are tender and caramelized, about 20 minutes, stirring occasionally. Aim for a lovely golden color.

  3. Add Balsamic Vinegar: Stir in balsamic vinegar and cook for another minute to enhance the flavor, then carefully remove the onions from the skillet and set aside.

  4. Cook the Chicken: In the same skillet, add the remaining olive oil and place your seasoned chicken breasts in. Cook until they are browned, about 5-7 minutes on each side, ensuring they are cooked through.

  5. Deglaze the Pan: Remove the chicken from the skillet and increase the heat to high. Pour in the beef broth to deglaze the skillet, scraping up any tasty bits stuck to the bottom.

  6. Thicken the Gravy: Reduce heat to medium, whisk in the all-purpose flour, and stir until the gravy thickens, about 3-4 minutes. Season with salt, pepper, and dried thyme.

  7. Combine Ingredients: Return the cooked chicken and caramelized onions to the skillet, stirring gently to coat them in the rich gravy. Sprinkle the shredded Swiss cheese evenly on top.

  8. Bake to Perfection: Preheat your oven to 350 °F and bake the dish for approximately 10 minutes, until the cheese is melted and bubbly, inviting everyone to the table!

  9. Serve Warm: Present your scrumptious French Onion Chicken over baguette slices or alongside fluffy egg noodles or rice, ensuring a satisfying meal for all.
