Creating French Onion Chicken and Rice can be a delightful experience if you follow these simple steps:

1. Sauté Onions: In a large skillet, heat olive oil and butter over medium heat. Add the sliced onions and cook until they are caramelized, about 10-15 minutes, stirring occasionally.

2. Season Chicken: While the onions are cooking, season the chicken breasts with garlic powder, salt, and pepper.

3. Brown Chicken: Push the caramelized onions to the side of the skillet and add the seasoned chicken breasts. Sear them for 3-4 minutes on each side until browned.

4. Add Broth and Rice: Pour in the chicken broth and Worcestershire sauce. Bring the mixture to a boil, then add the rice.

5. Simmer: Cover the skillet and reduce the heat to low. Let it simmer for about 20 minutes or until the rice is tender and the chicken is fully cooked.

6. Add Cheese: Once the rice is cooked, sprinkle the shredded Swiss cheese over the top of the chicken and cover again. Let it sit for another 5 minutes until the cheese is melted.

7. Garnish: Remove from heat and garnish with fresh thyme or parsley, if desired.

8. Serve: Dish out the chicken and rice onto plates, ensuring to include plenty of the caramelized onions and melted cheese.

These steps will guide you in creating this incredible dish effortlessly.
