Ingredients
- 6 bone-in, skin-on chicken thighs
- Kosher salt and freshly ground black pepper, to taste
- 2 tablespoons unsalted butter
- 8 ounces cremini mushrooms, halved
- 3 large shallots, diced
- 2 ribs celery, diced
- 3 cloves garlic, minced
- 3 tablespoons all-purpose flour
- ½ cup dry white wine
- 2 cups chicken stock
- 1 pound baby gold potatoes, halved
- 4 sprigs fresh thyme
- 1 sprig fresh rosemary
- 1 bay leaf
- ¼ cup heavy cream
Instructions
1. Preheat the Oven
Preheat your oven to 325°F (160°C).
Season the chicken thighs with salt and freshly ground black pepper.
2. Sear the Chicken
Melt the butter in a large Dutch oven or heavy pot over medium heat.
Place the chicken skin-side down and sear until golden brown, about 2–3 minutes per side.
Work in batches if necessary so the chicken browns properly. Remove the chicken from the pot and set aside.
3. Cook the Vegetables
In the same pot, add:
- Mushrooms
- Shallots
- Celery
Cook for 5–7 minutes, stirring occasionally, until the mushrooms soften and begin to brown.
Season lightly with salt and pepper.
Add the garlic and cook for about 1 minute until fragrant.
4. Build the Sauce
Sprinkle the flour over the vegetables and stir well, cooking for about 1 minute to remove the raw flour taste.
Slowly pour in the white wine, scraping the bottom of the pot to release all the flavorful browned bits.
Stir in the chicken stock, then add:
- Baby potatoes
- Thyme
- Rosemary
- Bay leaf
Return the seared chicken thighs to the pot.
5. Bake the Casserole
Transfer the Dutch oven to the oven and bake uncovered for 40–45 minutes.
The chicken should be fully cooked and the potatoes tender. The internal temperature of the chicken should reach 175°F (80°C).
6. Finish the Dish
Stir in the heavy cream, allowing the sauce to become slightly richer and smoother.
Taste and adjust seasoning with additional salt and pepper if needed.
Serve immediately.
Tips for the Best French Chicken Casserole
Use a heavy pot
A Dutch oven distributes heat evenly and works perfectly for this slow oven cooking.
Bone-in chicken is best
It provides more flavor and keeps the meat juicy.
Choose a drinkable wine
A dry white wine such as Pinot Grigio or Sauvignon Blanc works beautifully.
Don’t cover the pot
Cooking uncovered allows the chicken skin to stay crisp while the sauce reduces.
Substitutions and Variations
No mushrooms?
You can replace them with zucchini or eggplant, which absorb the sauce well.
No white wine?
Simply substitute with extra chicken stock.
Use dried herbs instead
If fresh herbs aren’t available, use 1 teaspoon dried herbs for every tablespoon of fresh herbs.
Use chicken breasts
Chicken breasts can be used, but cooking time may need adjustment since they cook faster.
What to Serve with French Chicken Casserole
This dish pairs beautifully with:
- Crusty artisan bread
- Buttered egg noodles
- Creamy mashed potatoes
- Roasted vegetables
- Fresh green salad
The bread is especially perfect for soaking up the rich sauce.
Storage and Reheating
Leftovers store very well and the flavors become even better the next day.
- Store in an airtight container in the refrigerator for up to 4 days
- Reheat gently on the stovetop or in the microwave
