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
• 1 tablespoon 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. Make sure to rub the seasonings into the chicken for maximum flavor. 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. You don’t need to cook them all the way through, as they will finish cooking in the oven. 4. Once the chicken is browned, remove it from the skillet and set it aside on a plate. Cover it with aluminum foil to keep it warm.

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 should take about 15-20 minutes. You want them to be soft and golden brown, which will add a rich flavor to your casserole. 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 delicious brown bits into the broth. Let it simmer for about 5 minutes, allowing the flavors to meld together. 7. After simmering, stir in the heavy cream. Mix well and let it cook for an additional 2-3 minutes until the sauce thickens slightly. Remove the skillet from 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-coated. The creamy sauce will keep the chicken moist and flavorful. 10. Now, sprinkle the shredded Gruyère cheese evenly over the top of the casserole. This cheese will melt beautifully and create a deliciously gooey topping. 11. Finally, add the French bread crumbs on top of the cheese. This will create a lovely crunchy texture once baked. If you want an extra layer of flavor, you can mix a little bit of melted butter into the bread crumbs before sprinkling them on top.

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 (the 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 a bit more and makes it easier to serve.

Serving the Casserole

15. To serve, use a large spoon to scoop out portions of the casserole. Make sure to get a bit of chicken, sauce, and the crunchy topping in each serving. 16. Garnish with freshly chopped parsley for a pop of color and added freshness. This will not only enhance the presentation but also add a nice herbal note to the dish. 17. Pair your French Onion Chicken Casserole with a simple green salad or some steamed vegetables for a complete meal. The creamy, savory flavors of the casserole are sure to be a hit with family and friends! Enjoy your delicious French Onion Chicken Casserole!
