Directions to follow
Now, let’s get into the nitty-gritty of preparing this delightful dish. Just follow these simple steps:
Sauté the onions: In a large skillet, heat the butter and olive oil over medium heat. Add the sliced onions, salt, pepper, and thyme. Cook, stirring frequently, until the onions are soft and caramelized – about 20 to 25 minutes. Stir in the garlic during the final minute. Pour in the beef broth and balsamic vinegar, simmer for 3 to 4 minutes, then remove from heat.
Prep the oven: Preheat your oven to 400°F (205°C).
Season the chicken: Rub the chicken breasts with olive oil, then season with paprika, onion powder, salt, and pepper. For a bit of extra flavor, sear the chicken in a hot pan for 2 to 3 minutes per side (this step is optional but recommended for added depth).
Assemble the dish: Spread the caramelized onions in a baking dish. Place the seasoned chicken on top, spoon the onion mixture over the chicken, and finally, cover everything generously with cheese.
Bake to perfection: Bake uncovered for 25 to 30 minutes until the chicken reaches an internal temperature of 165°F and the cheese is melted and bubbly.
Garnish and serve: Sprinkle with fresh parsley or thyme before serving, and enjoy your masterpiece with your choice of sides!

Pro chef tips
Here are some handy tips to elevate your cooking:
- Caramelizing is key: Don’t rush this process! Low and slow cooking allows the onions to develop that deep, rich flavor.
- Experiment with cheese: While mozzarella or Gruyere is traditional, feel free to mix it up with smoked Gouda or a sharp cheddar for a different flavor profile.
- Marinate the chicken: If time allows, marinate your chicken in the spices and oil for a couple of hours prior. This will enhance the flavor even more.
Creative twists
Feel free to customize this recipe to suit your taste:
- Add mushrooms: Sauté some chopped mushrooms along with the onions for added texture and earthy flavors.
- Spice it up: Introduce a pinch of cayenne pepper or red pepper flakes for a touch of heat.
- Vegetarian version: Substitute the chicken with hearty vegetables like eggplant or portobello mushrooms for a satisfying vegetarian bake.
