Ingredients You’ll Need
The beauty of French Chicken Casserole comes from its humble, wholesome ingredients. Each one plays a role—adding richness, depth, or a pop of color to the final dish. Gather these essentials for a meal that’s as impressive as it is comforting.
- Chicken Thighs: Bone-in, skin-on thighs stay juicy and flavorful, plus the crispy skin is irresistible.
- Olive Oil: Adds a subtle fruitiness and helps brown the chicken beautifully.
- Unsalted Butter: Lends richness and a silky texture to the sauce.
- Onion: Chopped onion gives sweetness and depth as the base of your casserole.
- Garlic: Fresh minced garlic infuses the dish with classic French flavor.
- Carrots: Sliced carrots add color, gentle sweetness, and a tender bite.
- Mushrooms: Cremini or white mushrooms soak up the sauce and add earthy notes.
- Tomato Paste: Just a spoonful gives the sauce body and a subtle tang.
- Dried Thyme: Essential for a true French flavor profile—earthy and aromatic.
- Dried Rosemary: A little goes a long way to add piney, herbal notes.
- Dry White Wine: Deglazes the pan, lifts all those savory bits, and brightens the sauce.
- Chicken Broth: Creates depth and brings everything together in a savory embrace.
- Heavy Cream: Adds luxurious creaminess and a soft finish to the sauce.
- Salt and Black Pepper: Simple seasoning is key—taste and adjust as you go.
- Fresh Parsley: Chopped parsley brings freshness and a splash of green on top.
How to Make French Chicken Casserole
Step 1: Sear the Chicken
Start by preheating your oven to 375°F (190°C). Pat the chicken thighs dry and season generously with salt and pepper. In a large oven-safe skillet or Dutch oven, heat olive oil and butter over medium-high heat until the butter foams. Lay in the chicken, skin side down, and let it sizzle until the skin turns deeply golden and crisp, about 5–6 minutes. Flip and sear the other side for another 2–3 minutes. Remove the chicken to a plate—you’re already building layers of flavor.
Step 2: Sauté the Vegetables
In the same skillet (don’t wipe it out!), add the chopped onion and sliced carrots. Cook for 3–4 minutes, stirring occasionally, until the onion turns translucent and the carrots start to soften. Toss in the garlic and mushrooms, stirring for another 3–4 minutes as the mushrooms release their juices and start to brown. This is where the kitchen starts smelling incredible.
Step 3: Build the Sauce
Stir in the tomato paste, thyme, and rosemary, letting the tomato paste cook for a minute to deepen its flavor. Pour in the white wine, using a wooden spoon to scrape up any browned bits stuck to the pan—these are pure gold for your sauce. Let it simmer for two minutes, then add the chicken broth and heavy cream, stirring to combine everything into a rich, velvety sauce.
Step 4: Assemble and Bake
Nestle the seared chicken thighs back into the pan, skin side up, making sure each piece gets a spoonful of that glorious sauce. Transfer the skillet, uncovered, to the preheated oven and bake for 30–35 minutes. The chicken will finish cooking gently, soaking up all the flavors, while the sauce bubbles and thickens. Your French Chicken Casserole is almost ready!
Step 5: Rest and Garnish
Carefully remove the pan from the oven and let your casserole rest for about five minutes. This short wait lets the juices redistribute and the sauce settle. Finish with a generous sprinkle of fresh parsley for color and an herby lift.
How to Serve French Chicken Casserole

Garnishes
A shower of freshly chopped parsley is classic, but you can also add a touch of lemon zest or a few extra sprigs of thyme for a pop of color and brightness. The fresh herbs awaken the rich, creamy sauce and add a pretty flourish that makes each plate feel special.
Side Dishes
Serve your French Chicken Casserole with something that soaks up all that dreamy sauce—think crusty French bread, creamy mashed potatoes, or a fluffy bed of white rice. For a lighter touch, a crisp green salad with a mustardy vinaigrette balances the richness perfectly.
Creative Ways to Present
For a rustic look, bring the skillet straight from oven to table for family-style serving. For individual portions, plate a chicken thigh over a scoop of mashed potatoes and ladle sauce over the top. Or, for a dinner party twist, serve in mini cocottes for each guest—a chic nod to French bistro style.
Make Ahead and Storage
Storing Leftovers
Let the casserole cool completely before transferring it to an airtight container. Refrigerate for up to 3 days. The flavors deepen and meld as it rests, making the leftovers even more irresistible.
Freezing
French Chicken Casserole freezes surprisingly well. Cool the casserole, then portion into freezer-safe containers. Freeze for up to 2 months. When you’re ready to enjoy, thaw in the refrigerator overnight for best texture.
Reheating
To reheat, gently warm the casserole in a covered ovenproof dish at 325°F (163°C) until hot, or microwave individual portions, stirring halfway through. Add a splash of broth or cream if the sauce has thickened too much in the fridge.
FAQs
Can I use boneless chicken thighs instead of bone-in?
Absolutely! Boneless thighs work well and make serving a breeze. Just reduce the baking time by about 5–8 minutes, as they cook more quickly than bone-in pieces.
What wine is best for French Chicken Casserole?
A dry white wine like Sauvignon Blanc, Pinot Grigio, or Chardonnay works beautifully. Choose something you’d enjoy drinking—a good wine makes all the difference in the sauce.
Can I make this casserole dairy-free?
Yes! Swap the butter for olive oil and use a dairy-free cream substitute, such as coconut cream (unsweetened). The sauce will still be luscious, though the flavor will change slightly.
How do I make this gluten-free?
This French Chicken Casserole is naturally gluten-free as long as you use gluten-free chicken broth. Double-check all your ingredients, and you’re set for a safe, hearty meal.
Can I add more vegetables to the casserole?
Definitely! Feel free to toss in diced potatoes, parsnips, or even a handful of spinach just before baking for extra color and nutrition. Just keep in mind that extra veggies may need a little more seasoning.
Final Thoughts
If you’re craving a comforting dinner that feels both special and effortless, give this French Chicken Casserole a try. It’s a dish that brings warmth and joy to any table, and I promise—after one bite, you’ll want to make it again and again.

For Cooking
- 1 tablespoon olive oil

- 1 cup dry white wine
- 1 cup chicken broth

Instructions
- Preheat and Season: Preheat your oven to 375°F (190°C). Season the chicken thighs generously with salt and black pepper on both sides to enhance flavor.
- Sear the Chicken: Heat olive oil and unsalted butter in a large oven-safe skillet or Dutch oven over medium-high heat. Place the chicken thighs skin side down and sear until the skin is golden brown and crisp, about 5 to 6 minutes. Flip and cook for an additional 2 to 3 minutes, then remove the chicken from the pan and set aside.
- Sauté Vegetables: In the same skillet, add the chopped onion and sliced carrots. Cook for 3 to 4 minutes until they soften. Add minced garlic and sliced mushrooms, cooking an additional 3 to 4 minutes until the mushrooms begin to brown and release their moisture.
- Add Flavorings and Deglaze: Stir in the tomato paste, dried thyme, and dried rosemary to coat the vegetables. Pour in the dry white wine, scraping the bottom of the pan to loosen any browned bits, then simmer the mixture for 2 minutes to reduce slightly.

- Return Chicken and Bake: Place the chicken thighs back into the skillet with the skin side up. Spoon some of the sauce over the chicken to keep it moist.
