Step‑by‑Step Instructions for Creamy French Chicken Casserole
Step 1: Prepare the Chicken
Begin by seasoning the bone-in skin-on chicken thighs generously with kosher salt and black pepper on all sides. This initial step ensures that your chicken is flavorful throughout the cooking process. Set the seasoned chicken aside as you prepare for the next step, allowing the spices to infuse a bit while you work.
Step 2: Sear the Chicken
In a large Dutch oven, melt 2 tablespoons of unsalted butter over medium-high heat until bubbling. Carefully add the chicken thighs, skin-side down, and brown them for 5-7 minutes on each side until golden brown and crisp. This step builds rich flavor; once browned, transfer the chicken to a plate and set aside.
Step 3: Sauté Vegetables
In the same Dutch oven, add 1 cup of diced shallots and 1 cup of chopped celery. Sauté for 3-4 minutes until the vegetables are softened and fragrant. Then, incorporate 8 ounces of sliced cremini mushrooms and 3 minced garlic cloves. Continue to cook for an additional minute, stirring occasionally until the mushrooms release their juices and the garlic is aromatic.
Step 4: Create the Roux
Sprinkle in ¼ cup of all-purpose flour and stir vigorously for about 2 minutes, allowing the flour to cook and absorb the moisture from the vegetables. This roux will help thicken your creamy sauce later. Be sure to keep stirring to prevent burning, creating a smooth mixture for the next step.
Step 5: Deglaze
Pour in 1 cup of dry white wine, stirring constantly to deglaze the pot. Scrape up any brown bits stuck to the bottom, and let the wine reduce by half, about 3-4 minutes. This process intensifies the flavors, adding depth to your Creamy French Chicken Casserole.
Step 6: Add Potatoes and Herbs
Once the wine has reduced, add 2 cups of chicken stock, stirring to combine. Then, toss in 1 pound of baby gold potatoes, cut in half, along with a handful each of fresh thyme and rosemary, plus 1 bay leaf. Nestle the seared chicken thighs back into the pot, partially submerging them in the mixture.
Step 7: Braise
Cover the Dutch oven with a lid and reduce the heat to low. Let everything simmer for about 30 minutes or until the chicken is cooked through and the potatoes are tender. During this time, the flavors will meld beautifully, culminating in a savory sauce for your casserole.
Step 8: Finish with Cream
After 30 minutes, remove the lid and stir in 1 cup of heavy cream. Allow the mixture to simmer uncovered for an additional 5 minutes, which thickens and enriches the sauce. Now’s the time to taste and adjust the seasoning with more salt and pepper to ensure your Creamy French Chicken Casserole is just right before serving.

Creamy French Chicken Casserole Recipe FAQs
How do I choose the best chicken for this casserole?
Absolutely! For the best results, select bone-in skin-on chicken thighs, as they provide both flavor and moisture. Look for firm, fresh meat without signs of discoloration or a strong odor. If you prefer, chicken breasts can also be used for a leaner option, but they’ll be less juicy.
What’s the best way to store leftovers of this casserole?
Very simply! Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove or in the oven to maintain creaminess. Just remember to add a splash of water or cream if the sauce thickens too much during storage.
Can I freeze the Creamy French Chicken Casserole?
Absolutely! You can freeze this casserole for up to 2 months. To do so, cool the assembled casserole completely, then cover it tightly with plastic wrap and foil or transfer it to a freezer-safe container. When you’re ready to enjoy, thaw it overnight in the fridge and reheat in a 350°F (175°C) oven until warmed through—about 20 to 30 minutes.
What should I do if my sauce is too thick?
No worries! If your sauce ends up thicker than you’d like, simply stir in a little chicken stock, cream, or even water until you reach your desired consistency. Start with a tablespoon at a time and mix well before adding more, so you can control the final texture.
Can I adjust the recipe for dietary restrictions or allergies?
Certainly! If you’re cooking for someone with dietary restrictions, consider these swaps: use gluten-free flour instead of all-purpose flour, replace heavy cream with low-fat milk or a dairy-free alternative, and ensure your chicken stock is low-sodium or vegetable-based for vegetarians. Always double-check ingredient labels for potential allergens!
How do I know when the chicken is fully cooked?
You’re in good hands! The chicken should reach an internal temperature of 165°F (75°C) to be safely consumed. Use a meat thermometer for the best accuracy. If you don’t have one, make sure that juices run clear when you pierce the chicken with a fork; there should be no pink meat remaining.
