Kitchen Equipment Needed

• Large skillet
• Baking dish (9×13-inch recommended)
• Tongs
• Measuring cups and spoons

Ingredients

4 boneless, skinless chicken breasts
1 tbsp olive oil
2 large onions, thinly sliced
1 tsp sugar
2 cups beef broth
1 tsp Worcestershire sauce
1/2 tsp garlic powder
1/2 tsp thyme
Salt and pepper to taste
1 1/2 cups shredded mozzarella cheese
1/2 cup grated Parmesan cheese
1 tbsp chopped parsley (optional, for garnish)

Directions

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Caramelize the Onions: Heat olive oil in a large skillet over medium heat. Add the sliced onions and sugar, stirring occasionally, until the onions are golden and caramelized, about 20-25 minutes.
3. Add Broth and Seasoning: Stir in beef broth, Worcestershire sauce, garlic powder, thyme, salt, and pepper. Simmer for 5 minutes, then remove from heat.
4. Sear the Chicken: Season the chicken breasts with salt and pepper. Heat a bit of olive oil in the same skillet over medium-high heat. Sear the chicken for 2-3 minutes on each side until golden (but not fully cooked).
5. Assemble the Bake: Transfer the chicken breasts to a baking dish. Pour the caramelized onions and broth mixture over the chicken, ensuring they’re evenly coated.
6. Add Cheese: Sprinkle mozzarella and Parmesan cheese evenly over the top.
7. Bake: Bake in the preheated oven for 20-25 minutes, or until the chicken is cooked through and the cheese is bubbly and golden.
8. Garnish and Serve: Let the dish rest for 5 minutes before garnishing with parsley and serving.

Expert Tips

Caramelizing Onions: Be patient and cook the onions over medium heat for the best flavor. Stir occasionally to prevent burning.

Cheese Variations: Gruyère or Swiss cheese can be substituted for mozzarella for a more traditional French onion flavor.

Broil for Extra Color: For a golden, bubbly cheese topping, broil the dish for 2-3 minutes after baking.
