How to Make French Chicken Casserole Recipe
Step 1: Prepare and Sear the Chicken
Begin by preheating your oven to 375°F (190°C). Season the chicken thighs generously with salt and pepper. Heating olive oil in a large ovenproof skillet or Dutch oven, sear the chicken skin-side down for 4 to 5 minutes on each side until golden and crispy. This step locks in the juices and builds flavor. Once seared, set the chicken aside – don’t worry, the magic is just getting started.
Step 2: Sauté the Aromatics
Using the same pan, toss in the diced onion first. Cooking it for about 5 minutes softens it perfectly, giving the casserole a subtle sweetness. Then add the minced garlic and cook just for a minute until fragrant. This layering of flavors forms the base that will carry the entire dish forward.
Step 3: Cook the Mushrooms
Next up, mushrooms go in. Stir them occasionally until they release their juices and turn beautifully golden, which should take around 6 to 8 minutes. This step adds a fantastic umami depth that melds perfectly with the chicken and herbs.
Step 4: Make the Sauce Base
Sprinkle the flour over the vegetables and stir well to make sure everything is coated evenly. This will help thicken the sauce later. Slowly pour in the white wine, making sure to scrape the bottom of the pan to deglaze it – all those browned bits are pure flavor gold. Follow that with the chicken broth, Dijon mustard, fresh thyme leaves, and bay leaves. Bring this mixture to a gentle simmer and let those flavors mingle elegantly.
Step 5: Combine and Bake
Return the chicken thighs to the skillet, placing them skin-side up so they stay crispy. Spoon some of the sauce over each piece, then place the skillet uncovered into the oven. Bake for 30 minutes, allowing the chicken to tenderize and soak up all those lovely herbs and aromatics.
Step 6: Finish with Cream and Bake Again
After the initial baking, stir in the heavy cream to give the sauce a rich, silky texture. Pop the casserole back into the oven for another 10 minutes, just enough time for the sauce to thicken slightly and coat the chicken in velvety goodness.
How to Serve French Chicken Casserole Recipe
Garnishes
Just before serving, sprinkle freshly chopped parsley over the casserole. This simple garnish brings a burst of fresh color and a slight herbal brightness that balances the creamy sauce perfectly. It’s the little touches like this that elevate the entire experience at the table.
Side Dishes
This casserole pairs wonderfully with buttery mashed potatoes or fluffy rice to soak up every drop of that delicious sauce. For a lighter option, serve it alongside a crisp green salad or roasted seasonal vegetables. No matter your choice, the sides will help round out the meal beautifully.
Creative Ways to Present
For a rustic presentation, serve the casserole directly from the skillet at the center of the table – it adds a warm, communal vibe to your meal. Alternatively, plate individual portions and drizzle extra sauce over the top, garnishing with parsley and a lemon wedge for a bright contrast. Serving it in colorful casserole dishes also makes the meal feel extra inviting.
Make Ahead and Storage
Storing Leftovers
This French Chicken Casserole Recipe keeps really well in the refrigerator for up to 3 days. Be sure to let it cool completely before transferring to an airtight container. The flavors actually deepen overnight, making leftovers taste even better the next day.
Freezing
If you want to enjoy this casserole later, freezing is a great option. Freeze it in portions or as a whole, well-wrapped in freezer-safe containers for up to 2 months. When frozen, the texture and flavor hold up wonderfully, making it an easy and delicious meal to pull out on busy nights.
Reheating
Gently reheat leftovers in the oven at 325°F (160°C) until warmed through, or use the stovetop to avoid drying out the chicken. If reheating from frozen, thaw overnight in the fridge first for even warming and to preserve that creamy sauce consistency.
FAQs
Can I use chicken breasts instead of thighs?
Absolutely! While thighs stay juicier and more flavorful, chicken breasts can be used if you prefer a leaner option. Just be careful not to overcook them as they tend to dry out faster.
Is it necessary to use white wine in the recipe?
White wine adds acidity and complexity to the sauce, but if you prefer, you can substitute it with additional chicken broth or a splash of white grape juice for a non-alcoholic version.
Can I make this recipe gluten-free?
Yes! Replace the all-purpose flour with a gluten-free flour blend or cornstarch for thickening the sauce. The rest of the ingredients are naturally gluten-free.
How do I get the chicken skin crispy after baking?
If you want extra crispy skin, you can broil the casserole for the last 2-3 minutes, watching carefully to avoid burning. This step crisps up the skin beautifully without drying out the meat.
Can this recipe be doubled to serve a larger group?
Definitely! Just increase the ingredients accordingly and use a larger ovenproof dish. Bake times might be a bit longer depending on the size and depth of your casserole, so keep an eye on the chicken’s internal temperature.

Instructions
- Preheat Oven: Preheat your oven to 375°F (190°C) to prepare for baking the casserole.
- Season Chicken: Pat the chicken thighs dry and season them generously with salt and pepper on both sides.
- Sear Chicken: Heat olive oil in a large ovenproof skillet or Dutch oven over medium-high heat. Place the chicken thighs skin-side down and sear for 4-5 minutes or until the skin is golden and crisp. Flip and sear the other side for 4-5 minutes. Remove chicken and set aside.
- Sauté Onion and Garlic: In the same skillet, reduce heat to medium and add diced onion. Cook for about 5 minutes until soft and translucent. Add minced garlic and sauté for an additional 1 minute, stirring to prevent burning.
- Cook Mushrooms: Add sliced mushrooms to the skillet and cook until they release their juices and become golden brown, about 6-8 minutes.
- Add Flour: Sprinkle flour over the cooked vegetables and stir well for about 1-2 minutes to cook the flour and make a roux, which will thicken the sauce.

- Garnish and Serve: Remove bay leaves from the casserole. Sprinkle chopped fresh parsley over the top for a bright, fresh finish and serve hot.
Notes
- Use bone-in, skin-on chicken thighs for maximum flavor and moisture retention.
- If you don’t have a Dutch oven, an ovenproof skillet works well; otherwise transfer to a casserole dish before baking.
- Dry white wine is best for deglazing; substitute with additional chicken broth if needed.
- Make sure not to overcook the chicken during searing, as it will finish baking in the oven.
- Adjust seasoning with salt and pepper at the end as needed, depending on broth saltiness.
- For a healthier alternative, substitute heavy cream with half-and-half or a light cream.
