Ingredients:
- 4 boneless, skinless chicken breasts
- 2 large onions, thinly sliced
- 3 tablespoons olive oil
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 teaspoon garlic powder
- 1 teaspoon dried thyme
- 1 cup beef broth
- 1 cup heavy cream
- 1 cup shredded Gruyère cheese
- 1 cup French bread crumbs
- 2 tablespoons fresh parsley, chopped (for garnish)
Preparing the Chicken
1. Start by preheating your oven to 375°F (190°C). This will ensure that your casserole cooks evenly and thoroughly. 2. While the oven is heating, take your boneless, skinless chicken breasts and season them with salt, black pepper, garlic powder, and dried thyme. I like to rub the seasonings into the chicken to ensure they are well-coated. 3. In a large skillet, heat 2 tablespoons of olive oil over medium-high heat. Once the oil is hot, add the seasoned chicken breasts. Sear them for about 5-7 minutes on each side until they are golden brown. This step adds a lovely depth of flavor to the chicken. 4. Once the chicken is browned, remove it from the skillet and set it aside on a plate. Dont worry about cooking it all the way through at this point; it will finish cooking in the oven.Caramelizing the Onions
5. In the same skillet, add the remaining tablespoon of olive oil. Toss in the thinly sliced onions. Stir them occasionally, allowing them to cook down and caramelize. This process usually takes about 15-20 minutes. You want them to be soft and golden brown, which brings out their natural sweetness. 6. Once the onions are caramelized, pour in the beef broth. Scrape the bottom of the skillet with a wooden spoon to deglaze it, incorporating all those flavorful bits stuck to the pan. Let the mixture simmer for about 5 minutes, allowing the broth to reduce slightly. 7. After simmering, stir in the heavy cream. This will create a rich and creamy sauce that will coat the chicken and onions beautifully. Allow the mixture to simmer for another 2-3 minutes, then remove it from the heat.Assembling the Casserole
8. In a large casserole dish, place the seared chicken breasts in a single layer. Make sure they are evenly spaced out. 9. Pour the caramelized onion and cream mixture over the chicken, ensuring that each piece is well-covered. The creamy sauce will seep into the chicken, making it incredibly tender and flavorful. 10. Now, its time to add the cheese! Sprinkle the shredded Gruyère cheese evenly over the top of the casserole. This cheese melts beautifully and adds a wonderful nutty flavor. 11. Finally, sprinkle the French bread crumbs over the cheese layer. This will create a delightful crunchy topping once baked. If you want an extra crispy topping, you can drizzle a little olive oil over the bread crumbs.Baking the Casserole
12. Cover the casserole dish with aluminum foil to prevent the top from browning too quickly. Place it in the preheated oven and bake for 25 minutes. 13. After 25 minutes, remove the foil and continue baking for an additional 15-20 minutes, or until the cheese is bubbly and golden brown, and the chicken is cooked through (internal temperature should reach 165°F or 74°C). 14. Once done, remove the casserole from the oven and let it sit for about 5-10 minutes. This resting time allows the sauce to thicken slightly and makes it easier to serve.Serving the Casserole
15. To serve, use a large spoon to scoop out portions of the casserole. I like to garnish each serving with a sprinkle of fresh parsley for a pop of color and freshness. 16. This French Onion Chicken Casserole pairs wonderfully with a simple green salad or some steamed vegetables. The creamy, savory flavors of the casserole are sure to impress your family and friends. 17. Enjoy your delicious creation! I love how this dish combines the comforting flavors of French onion soup with tender chicken, making it a perfect meal for any occasion.
