How to Make French Chicken Casserole Recipe

Step 1: Preheat and Prepare the Chicken

Begin by preheating your oven to 375°F (190°C). Meanwhile, season the chicken thighs generously with salt and pepper. This initial seasoning is crucial for flavor as it penetrates the meat during cooking.

Step 2: Sear the Chicken

Heat the olive oil in a large ovenproof skillet or Dutch oven over medium-high heat. Place the chicken thighs skin-side down and sear for 4 to 5 minutes until the skin is beautifully golden and crispy. Flip and cook the other side for an additional 4 to 5 minutes before setting the chicken aside. Searing locks in juices and forms a delicious crust, which will become a highlight of the dish.

Step 3: Sauté the Aromatics

In the same skillet, add diced onions and cook for about 5 minutes until they soften and become translucent. Add minced garlic and cook for one more minute until fragrant. This step releases the base flavors that are essential to building your sauce.

Step 4: Cook the Mushrooms

Add the sliced mushrooms to the skillet and cook until they release their juices and begin to turn a golden brown, around 6 to 8 minutes. This process intensifies their earthy flavor and adds a wonderful savory complexity to the casserole.

Step 5: Thicken the Sauce

Sprinkle the flour evenly over the vegetables, stirring to ensure every piece is coated. The flour acts as a thickening agent that will help create that creamy texture characteristic of a classic French Chicken Casserole Recipe.

Step 6: Deglaze and Simmer

Pour in the dry white wine and use a wooden spoon to scrape all those delicious browned bits off the bottom of the skillet. Then stir in chicken broth, Dijon mustard, fresh thyme leaves, and bay leaves. Bring the mixture to a gentle simmer. This combination creates a deeply flavored sauce that ties everything together.

Step 7: Bake the Casserole

Return the chicken to the skillet, placing it skin-side up, and spoon some of the sauce over the top. This keeps the chicken moist and flavorful during baking. Place the skillet in the oven and bake uncovered for 30 minutes, allowing the flavors to meld and the chicken to cook through.

Step 8: Finish with Cream and Bake More

Remove the skillet briefly from the oven and stir in the heavy cream. This addition creates a velvety smooth sauce that elevates the entire dish. Return the casserole to the oven and bake for another 10 minutes, or until the sauce thickens slightly and becomes luscious.

Step 9: Garnish and Serve

Before serving, sprinkle freshly chopped parsley over the casserole. This simple touch adds a burst of color and fresh, herbaceous brightness to each mouthwatering bite.

Freezing

This French Chicken Casserole Recipe freezes beautifully. Cool it completely, then transfer portions to freezer-safe containers or bags. It will keep well for up to 2 months, perfect for quick meals on busy days.

Reheating

To reheat, thaw overnight in the fridge if frozen, then warm gently in a covered skillet over medium-low heat or in the oven at 325°F (160°C) until heated through. Stir occasionally to maintain sauce consistency and avoid drying out the chicken.

FAQs

Can I use chicken breasts instead of thighs for this casserole?

Absolutely, though chicken thighs tend to stay juicier and more flavorful after baking. If using breasts, consider adjusting cooking time to avoid drying them out and maybe brining them briefly beforehand for extra moisture.

Is it necessary to use white wine in the recipe?

While white wine adds an important layer of acidity and depth, you can substitute it with additional chicken broth and a splash of lemon juice if you prefer or do not have wine on hand. The sauce will still be delicious.

Can I prepare parts of this casserole in advance?

Yes, you can sauté the chicken and vegetables the day before, then combine and bake just before serving. This saves time and allows flavors to meld even more beautifully.

What type of mushrooms work best in this recipe?

Cremini or button mushrooms are ideal since they cook nicely and offer a mild earthy flavor, but feel free to mix in shiitake or maitake for unique textures and a deeper mushroom taste.

How can I make this casserole gluten-free?

Simply substitute the all-purpose flour with a gluten-free flour blend or cornstarch to thicken the sauce. Just be sure to mix well to avoid lumps and adjust amounts if needed for the right sauce consistency.
