Making French Onion Chicken and Rice is easy if you follow these steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Sauté Onions: In a large oven-safe skillet, heat olive oil and butter over medium heat. Add the sliced onions and cook until they are caramelized, approximately 15-20 minutes.
3. Season Chicken: Season the chicken breasts with salt, pepper, garlic powder, and thyme.
4. Brown Chicken: Push the caramelized onions to the side of the skillet and add the chicken breasts. Sear the chicken for about 4-5 minutes on each side until golden brown.
5. Add Rice: Stir in the rice, allowing it to toast for a minute with the onions and chicken.
6. Pour Broth: Pour in the chicken broth, mixing well to combine. Bring the mixture to a simmer.
7. Cover and Bake: Cover the skillet with a lid or aluminum foil and transfer it to the preheated oven. Bake for 25-30 minutes, or until the rice is cooked and the chicken is tender.
8. Add Cheese: Remove the skillet from the oven and sprinkle the Gruyère cheese on top. Return it to the oven for an additional 5-10 minutes until the cheese is melted and bubbly.
9. Rest: Remove from the oven and let it rest for about 10 minutes before serving.
10. Garnish: Sprinkle freshly chopped parsley on top for an added pop of color and flavor.

By following these steps, you’ll create an incredible dish that is sure to become a favorite in your home.
