FRENCH CHICKEN CASSEROLE Ingredients

• Everything you need to create this cozy delight.

For the Chicken

Bone-in, skin-on chicken thighs – Main protein source that provides rich flavor and moisture; can substitute with boneless thighs or chicken breasts.
Kosher salt and freshly ground black pepper – Essential for enhancing all flavors; adjust to your taste.

For the Sauce and Vegetables

Unsalted butter – Adds richness and helps brown the chicken for a golden color.
Cremini mushrooms – Contribute umami and delightful texture; swap with zucchini or eggplant if desired.
Large shallots – Provide a sweet and deep flavor; regular onions can be used if shallots aren’t available.
Celery – Adds a pleasant crunch and balances flavors within the casserole.
Garlic – Imparts aromatic depth; a must for enhancing the overall flavor.
All-purpose flour – Thickens the sauce for a hearty, gravy-like consistency; can be replaced with gluten-free flour.
Dry white wine (e.g., Pinot Grigio or Sauvignon Blanc) – Introduces acidity and flavor complexity; choose one you enjoy drinking.
Chicken stock – Forms the base liquid for the sauce, infusing it with flavor; vegetable stock can replace for a non-meat version.

For the Potatoes and Herbs

Baby gold potatoes – Hearty and tender; their small size reduces prep time while adding comfort to the dish.
Fresh thyme, rosemary, and bay leaf – These aromatic herbs elevate the flavors, making your dish more delightful.
Heavy cream – Adds a luxurious richness to the sauce; can substitute with half-and-half or whole milk for a lighter option.

This French Chicken Casserole is not just a dish; it’s a heartwarming experience waiting to be savored!

How to Make French Chicken Casserole

Preheat oven: Begin by setting your oven to 325°F (163°C). This gentle heat ensures the chicken cooks evenly and the flavors meld beautifully during baking.
Prepare chicken: Season the chicken thighs generously with kosher salt and freshly ground black pepper. In a Dutch oven, sear the chicken skin-side down until golden brown – about 2-3 minutes on each side. Once they’re perfectly browned, remove them and set aside.
Cook vegetables: In the same pot, add unsalted butter and let it melt. Toss in the cremini mushrooms, large shallots, and celery. Sauté for 5-7 minutes until everything is tender, and then add minced garlic, cooking until fragrant.
Thicken the sauce: Sprinkle all-purpose flour over the sautéed veggies, stirring well. Pour in the dry white wine, scraping up any tasty browned bits from the bottom of the pot to build depth in flavor.
Add remaining ingredients: Slowly pour in chicken stock while stirring, then add the baby gold potatoes and fresh herbs. Finally, return the seared chicken to the pot, nestling it among the vegetables.
Bake: Cover your Dutch oven and let it bake in the preheated oven for 40-45 minutes. The chicken should reach an internal temperature of 175°F (79°C), and the potatoes will be tender when poked with a fork.
Finish sauce: Carefully stir in heavy cream, tasting the sauce and adjusting seasoning if needed. Serve the casserole hot, letting the aroma fill your kitchen!

Optional: Garnish with extra fresh herbs for a pop of color and flavor.

To maintain its wonderful flavor, allow your casserole to cool completely, then transfer it to an airtight container.
