Step‑by‑Step Instructions for French Chicken Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 325°F (165°C). This step is crucial for ensuring your French Chicken Casserole bakes evenly, allowing the flavors to meld together beautifully. While the oven warms up, get your ingredients organized for a seamless cooking experience.
Step 2: Season the Chicken
Generously season the bone-in, skin-on chicken thighs with kosher salt and freshly ground black pepper. This seasoning enhances the flavor of the chicken, which will be the star of your casserole. Once seasoned, set the chicken aside as you prepare to sauté it.
Step 3: Sear the Chicken
In a heavy-bottomed Dutch oven, melt a couple of tablespoons of unsalted butter over medium heat. When the butter is nice and hot, add the chicken thighs skin-side down, searing them for about 2-3 minutes until they develop a golden brown crust. Once browned, remove the chicken from the pot and set it aside.
Step 4: Sauté the Vegetables
In the same pot, add the chopped cremini mushrooms, thinly sliced shallots, and chopped celery. Sauté the mixture for about 5-7 minutes until the vegetables are tender and fragrant. Be sure to season them with salt to enhance their natural flavors, which will form a savory base for your casserole.
Step 5: Add Garlic
Add the minced garlic to the pot and cook for about 1 minute, stirring frequently until fragrant. This step is key to developing the aromatic depth of your French Chicken Casserole. The garlic should be lightly golden but not burnt to retain its vibrant flavor.
Step 6: Incorporate Flour
Sprinkle the all-purpose flour over the sautéed vegetables, stirring constantly for about 1 minute until the flour is lightly browned. This will create a roux that thickens your sauce as it cooks and adds a lovely, creamy texture to your casserole.
Step 7: Deglaze the Pot
Carefully pour in the dry white wine while scraping up any browned bits from the bottom of the pot, which adds layers of flavor to your dish. Allow the wine to simmer for a couple of minutes to reduce slightly before adding in the chicken stock, baby gold potatoes, fresh thyme, rosemary, and the bay leaf.
Step 8: Combine and Return Chicken
Return the seared chicken thighs to the pot, nestling them among the vegetables and potatoes. This will allow the chicken to soak up all the delicious flavors. Bring the mixture to a gentle simmer before placing the pot in the preheated oven.
Step 9: Bake the Casserole
Bake the casserole uncovered for 40-45 minutes. After this time, check that the chicken is cooked through and reaches an internal temperature of 175°F, and that the potatoes are tender. The top should look beautifully golden-brown, inviting you to enjoy the dish.
Step 10: Add Cream and Serve
Once baked, remove the pot from the oven and stir in the heavy cream, adjusting the seasoning as needed with additional salt and pepper. This final touch transforms your French Chicken Casserole into a creamy, comforting dish ready to be served hot to your family or guests.

Don’t worry! If you find that your chicken is overcooked, you can revive some moisture by stirring in a bit of chicken stock or heavy cream to have a creamier texture.
