Ingredients Quantity
Boneless, skinless chicken breasts 4
Olive oil 2 tablespoons
Large onions, thinly sliced 3
Cloves garlic, minced 2
All-purpose flour 2 tablespoons
Beef broth 1 cup
Shredded Gruyere or Swiss cheese 1 cup
Shredded mozzarella cheese 1/2 cup
Salt and black pepper To taste
Fresh thyme or parsley for garnish (optional) As needed


  1. Preparation: Preheat your oven to 375°F (190°C).
  2. Season Chicken: Season 4 boneless, skinless chicken breasts with salt and black pepper. Set aside.
  3. Sear Chicken: In a large oven-safe skillet, heat 2 tablespoons of olive oil. Sear chicken for 3-4 minutes on each side until golden brown. Remove and set aside.
  4. Caramelize Onions: In the same pan, cook 3 thinly sliced onions until caramelized (15-20 minutes). Add 2 minced cloves of garlic and cook for an additional 1-2 minutes.
  5. Create Sauce: Sprinkle 2 tablespoons of all-purpose flour over onions, stir, and cook for 1-2 minutes. Slowly pour in 1 cup of beef broth, stirring until the sauce thickens (2-3 minutes).
  6. Combine Ingredients: Return chicken to the pan, spoon onion sauce over them. Top with 1 cup of shredded Gruyere or Swiss cheese and 1/2 cup of shredded mozzarella cheese.
  7. Bake: Transfer the pan to the preheated oven and bake for 20-25 minutes or until the chicken is cooked through, and the cheese is melted and bubbly.
  8. Optional Broiling: For a golden finish, place the skillet under the broiler for 1-2 minutes.
  9. Garnish and Serve: Garnish with fresh thyme or parsley before serving.
